Lab #3: Isotonic contraction and the effect of load on skeletal muscles Abstract The job of the motor nervous system is to control certain elements in muscles simultaneously to ultimately produce movement. Movement of the body is the result of specialized cells directly associated with skeletal muscle. Skeletal muscles are voluntary muscle and must contract before movement can occur. We know the muscle team moving the arm is formed at the biceps and triceps. Biceps can bend the elbow‚ but

When the stimulus is delivered‚ the ermeability of the membrane at that point is changed; and c ‚ initiating the depolarization of the membrane. Almost as soon as the depolarization wave has begun‚ a repolarization wave follows it across the membrane. This occurs as b . Repolarization restores the h of the resting cell membrane

Write a review on the processes involved‚ emphasizing the role of satellite cells.” Muscle Cell Regeneration and the Impact of Ageing Introduction: Throughout normal life‚ skeletal muscles undergo repair and regeneration in response to injury through a process involving several sequential steps. A very important role in this regeneration

body is made up of a number of systems that all interlink and produce everything we need in order to survive. Within the body there is the digestive system; the circulatory system‚ the nervous system‚ the muscular system‚ the skeletal system and the reproductive system. These systems are all part of one another and they share organs‚ tissues and cells and that is how they interlink. The diagram above shows each system and where they are located in the body. Each system is shown in a different image

Principles of Anatomy and Physiology Functions of the skeletal system There are five main functions of the skeletal system. To protect‚ to support‚ movement‚ cell production and storage. The skeletal system protects delicate and important organs from harm. An example of this is the ribcage. This protects your heart and lungs from anything that tries to harm it. Another example is the brain. The brain is protected by the skull. The skeletal system also provides support for the body as it acts as a
