is taken into actual muscle contraction with the interaction of two types of proteins‚ actin and myosin. Different steps of activities are involved in muscle contraction. The sequence of contraction process is originated in the central nervous system. It can be either a voluntary activity from the brain or a reflex activity from the spinal cord. An action potential passes outward in a ventral root of the spinal cord as a motor neuron in the ventral horn is stimulated. The axon branch to supply

muscles are used to move bones‚ though some‚ such as the muscles in the face‚ are used to create movements below the skin. Unlike cardiac or smooth muscle‚ voluntary muscle can be controlled by the conscious mind. As a part of the musculoskeletal system‚ each voluntary muscle is used to help a person move around. Most are connected to bones by connective tissue called tendons. The muscle is attached to a bone at a location called its origin. It then runs along the length of the entire bone and is

cause of Polymyositis is unknown‚ but the disease shares many chareteristies with autoimmune disorders‚ in which your immune system attacks normal body components. Normally‚ your immune system works to protect your healthy cells from attacks by foreign substances‚ such as bacteria and viruses. If you have Polymyositis‚ an unknown cause may act as a trigger for your immune system to begin producing autoimmune antibodies that attack your on tissues. Many people with Polymyositis show a detectable level

Christopher Couchell Muscle Physiology Purpose: The Purpose of this exercise is to understand how muscle twitch‚ contract and react to different activities. Exercise 1: Muscle Twitch A. What is a muscle twitch? A muscle twitch is the fasciculation ‚ or "muscle twitch"‚ is a small‚ local‚ involuntary muscle contraction and relaxation visible under the skin. B. According to the graphs‚ which muscle has the fastest twitch? Why? The lateral rectus eye muscle has the fastest twitch.

IMPLICATIONS OF PHYSICAL DISABILTY Cerebral Palsy Cerebral Palsy affects people in different ways - some people experience minor motor skill problems‚ while others may be totally physically dependent. Messages from the brain can be distorted or mistimed causing increased muscle tension. Messages from the brain may also be mistimed‚ sent to the wrong muscle‚ or not sent at all. This affects the timing‚ quality and synchronisation of messages‚ generally resulting in erratic movement of the muscles
