...ciliary muscle. The ciliary muscle is attached to the lens via suspensory ligaments. Accommodation of the eye refers to the ability to adjust the strength of the lens. The strength of the lens depends on the shape of the lens. The shape of the lens is controlled by the ciliary muscle, which is attatched to the lens via suspensory ligaments. Accommodation refers to the ability to adjust the strength of the lens. The strength of the lens depends on the shape of the lens. The shape of the lens is controlled by ciliary muscles, which are attatched to the lens via suspensory ligaments. Accommodation refers to the ability of the eye to adjust the strength of the lens. The strength of the lens depends on the shape of the lens. The ciliary muscle controls the shape of the lens. The ciliary muscle attaches to the lens via the suspensory ligaments. When a person is focusing on something far in the distance, the ciliary muscle is relaxed. When the ciliary muscle is relaxed, the suspensory ligaments are taut, thus tension is placed on lens and it is pulled flat and is weak. This shape enables the person to accommodate more light rays, thus enable the image that is far away to be formed. When the person is looking at something near by, the ciliary muscle contracts. The contraction of the ciliary muscle results in the relaxation of the suspensory ligaments. This decreases the tension on the lens, thus the lens takes on a more rounded and stronger shape. The ciliary muscle is......

Frog Muscle Disection

...As you increase voltage to the muscle describe how it responds to the increased stimulus. As the voltage was increased from threshold to maximum voltage, there was a greater force in the muscle contraction. Once the maximum voltage (2500 mv) was reached, even if there was an increase in voltage, the force of the muscle contraction remained the same. 2. What was the smallest voltage required to produce a contraction (the threshold voltage)? What proportion of the fibers in the muscle do you think were contracting to produce this small response? 0.2500V , a small contraction of all the muscle fibers 3. What was the smallest voltage required to produce the maximum (largest) contraction? What proportion of the fibers in the muscle do you think were contracting to produce this maximal response? 0.6500V, all muscle fibers contracted maximally. 4. What do you conclude happened to the number of fibers contracting as the voltage was raised from threshold to that required to produce a maximal contraction? As the stimulus voltage is increased past the muscle’s threshold voltage, the amount of force in the entire muscle increases. Each time the voltage was increased the force generated from the muscle also increased. This occurs because, as the voltage increases, and is delivered to the whole muscle, more fibers are activated. This causes the total force produced by the muscle to increase. 5. In light of the all or none law of muscle contraction, how can you......

...Ashley Weiss Chapter 9 / 10 quiz 1. The thick filament which contain myosin are located in the H zone, M line and part of the A zone which is what is used for muscle contraction. The thin filaments consist of two strands of actin subunits twisted into a helix plus to types of regulatory proteins; troponin and tropomyosin. The sarcomere is the contractile unit, which is composed of myofilaments which also contain the A band, I band, H zone, Z disk and M line. Myofibrils are rod like contractile elements that occupy most if the muscle cell volume. Composed of saromeres arranged end to end they appear banded. The muscle fiber which is composed of many microfibrils is enclosed in endomysium and under that is the sarcolemma which houses the nuclei. Tendons connect muscles to their bony origins and insertions. Aponeuroses are layers of flat connective tissue (fascia) separating muscles from each other. The SR contain mitochondria and glycogen granules stored in the sarcoplasm which are involved in producing the energy for contraction. The fascicle is composed of many muscle fibers and is enclosed in the perimysium; the muscle is composed of many fascicles and is enclosed in the epimysium. The tubules of the sarcoplasmic reticulum have sac like terminal cisterns and the T tubules run between those. Spots that contain a t tubule and 2 terminal cisterns are called a triad. An action potential is carried down the sarcolemma to the neuromuscular junction . There are very......

Cardiac Muscle

...Cardiac Muscle Tissue and It’s Function There are different types of muscle tissue in the body. I will be focusing on cardiac muscle tissue and its functions. Cardiac muscle is located in the heart wall and its major function is to pump blood throughout the body. If you were to put cardiac muscle and skeletal side by side you would see that cardiac muscle fibers are shorter in length and less circular. They are described as: “Branched striated fibers with usually only one centrally located nucleus (occasionally two). (Jenkins&Tortora,(2012) p. 132) Cardiac muscle fibers connect to each other by intercalated discs. Intercalated disc are “Transverse thickenings of plasma membrane called intercalated disc which contain desmosomes and gap junctions.” (Jenkins&Tortora,(2012) p. 132) Desmosomes are the glue of the cardiac muscle they hold it together even through constant athletic movement. For example exercise, if there were no desmosomes in the cardiac muscle it would simple fall apart then minute you jumped on a treadmill or began and exercise routine. “Desmsomes strengthen tissues and hold fibers together during vigorous contractions.” (Jenkins&Tortora,(2012) p. 132) Gap junctions make it possible for action potentials to move through one muscle fiber to the next. “Gap junctions provide route for quick conduction of electrical signals throughout heart.” (Jenkins&Tortora,(2012) p. 132) We don’t have to tell our cardiac muscle to contract it does this all...

...Paper Review In life we have to make decision short term and long term decisions. Ever decision you make in life will always affect your future and can affect your well being. This is the same view that you can look at when dealing with financial situation which it is personal use, business, or organization. The decision that we make financially can be economic decisions and not always have to be personal in nature. When making decision for a company or organization you have to sometimes be transparent and look from every view and aspect, because this decision is not only going to affect you it can affect a small or large group of people and even a community just depending on what type of business and services are being offered. In this stimulation review paper I will be review the Cardiac’s Care Hospital’s financial accounting account. The hospital is experiencing some difficulties with accounting matters, capital shortage, capital expansion and funding options. During this review we will discuss some of there methods of accounting and see if it is some ideas or other tools that can be used to help them to better there financial issues. Capital shortage is a huge factor when running any type of business. Capital is the amount of current assets minus the amount of current liability as of a specific date. These amounts are obtained from the company’s balance sheet reports that. To give you a better understanding so that they hospital balance sheet is reporting that the......

Muscle Contraction

...Conor Harris 11/9/2015 In the experiment we performed in lab last week, our group’s objective was to measure the force output in the unit of Newtons (N) and Electromyography (EMG) output of an isometric hand contraction squeezing a ball in four varying wrist angles. This experiment was created with the intention to help us better understand how muscle force varies when muscle length varies. The title of the experiment is the “Length-Tension Experiment”. The Length-Tension relationship in anatomy refers to how the number of crossbridges depends on the amount of overlap between thick and thin fibers. Optimum amount of overlap will result in the greatest amount of tension. The optimum amount of overlap can be determined by the length of the sacromeres when the muscle is contracted. If the muscles are too stretched when contraction occurs, myosin will pull away from the actin and prevent cross bridge formation. Conversely, if muscles/sacromeres are too short at contraction cannot conduct signal efficiently because the crowded thin filaments disrupt the t-tubule’s arrangement in the myofibers. It is also essential to comprehend the relationship between myosin and actin. Myosin (thick filaments in sacromere) grabs onto actin (thin filaments in sacromere) and pulls, creating tension in the muscle. The contraction is caused by the previously described interaction between actin and myosin, resulting in the thin filaments being pulled closer to the M line of the sacromere,......

Lab 7

...Physiology Lab Dr. Xu 2 March 2016 Frog Skeletal Muscle Lab Introduction A biologist by the name Jan Swammerdam performed the first experiments on muscle physiology between 1661 and 1665. Swammerdam demonstrated that an isolated frog muscle can contract if the sciatic nerve is irritated with a metal object. Almost a century later, a physician by the name Luigi Galvani demonstrated that frog muscle responds to electrical currents. In the late 1840s, either Carlo Matteucci or Carl Ludwig attributed to the invention of the kymograph, which is illustrated as a rotating drum powered by a clockwork motor. The invention of the kymograph changed experimental physiology by allowing muscle contractions, and other actions, to be recorded and analyzed for the first time ever. Muscle cells, or muscle fibers, are defined as the basic unit of a muscle. Therefore, complete muscles are constructed from bundles of muscle fibers, but there are no gap junctions between adjacent cells so each fiber performs independently. Myofibrils establish an ordered structure for single muscle fibers. Every myofibril is comprised of actin and myosin. Actin and myosin are contractile proteins that can slide past each other when Ca2+ and ATP are present. A motor unit is described as a single motor neuron and all of its innervating muscle fibers. Like nerve tissue, muscle fibers produce an all-or-none response to a stimulus, generating a twitch. A single motor neuron supplies numerous muscle fibers to......

Electrical Stimulation

...INTRODUCTION: The skeletal muscle is an important organ in the human body that allows for movement and support of the skeleton, helping the body execute various tasks from precise control movements (writing a letter or picking up a chalk) to more abrupt, powerful movements (lifting weights or running). The skeletal muscle is one of the main types of muscle in the body (the other two being cardiac and smooth muscles) that allows movement by contraction of the muscles. When a motor unit, a single nerve that innervates all the muscle fibers, activates these muscles fiber, it causes a muscle contraction. These muscle contraction occurs when motor neurons from the spinal cord leaves and activates multiple muscle fibers, the number of muscle fibers depend on the type of muscle. According to the Hennemen size principle, muscles that react rapidly and exert fine control have smaller motor units than those with larger, weight-involving muscles, whose movements are less precise, will require larger motor units. The means of movement and force generation is based on the skeletal muscles contraction. Contractile units of the skeletal muscles include thick myosin and thin actin myofillaments or fillaments. Sarcomere is the smallest contractile unit of a muscle fiber. The repetition of the sarcomere structure make up myofibrils and hundreds to thousands of these myofibrils make up a single muscle fiber (Sherwood 258). Contraction is initiated by an increased in the intracellular......

Muscle Fatigue

...Muscle Fatigue: An Athletes Worst Nightmare Aschton Pitts English 101, Section 101 Ms. Kate Lavia-Bagley November 3, 2011 Muscle Fatigue: Chunks of bright green grass fly through the air. A man named Jimmy continuously digs his cleats into the ground. Jimmy is a professional soccer player who continuously strains his body to the max. He runs down a one-hundred-twenty yard field for ninety minutes straight-with little to no downtime. Blood, sweat and tears continuously drain from Jimmy as he constantly thrusts forward and accelerates to where he needs to be. Dribbling a ball down the field past defenders, while trying to focus on proper motion and footwork can be crazy. As he drives onward with dreams of a hatched white nylon in his future he keeps pushing. This starts to take a toll on Jimmy’s muscle groups. Lactic acid continues to build up in his abdominals and legs. Jimmy’s mind starts to wander as he thinks about his current exhaustion and fatigue. His rationale and decision making come into question by not only his coach but by his teammates as well. As the game wears on, Jimmy keeps pushing exerting energy with all his might. There then comes a point where his muscular frame cannot take the stress of physical activity anymore and he collapses. What is there to be done about the fatigue an endurance sport like this takes on his muscles, especially the brain? What elements fight against muscle fatigue, and what happens in their......
