Describe the role of calcium in muscle contraction‚ where it is stored‚ and how it is released and recycled. Calcium storage‚ release‚ and recycling Muscles need to be malleable or have plasticity in order to function correctly. This is where calcium comes into the picture. All muscles use calcium molecules for regulatory and signaling purposes. Contraction control and relaxation control by calcium is achieved first by the activation of troponin-tropomyosin with the actin filaments. The second

Your answer : d. An increase in muscle length will decrease the total force. Stop & Think Questions: Note
Premium Skeletal muscle Myosin Muscle
four (4) functional characteristics of all muscle tissues -Excitability or Responsiveness- The ability to receive and respond to a stimulus that is any change in the environment whether inside or outside the body. In the case of muscle ‚the stimulus is usually a chemical for example - a neurotransmitter released by a nerve cell‚ or a local change in ph. The response is generation of of an electrical impulse that passes along the sarcolemma of the muscle cell and causes the cell to contract. Contractility-

Kathleen thomason October 2‚ 2012 Skeletal Muscle physiology exercise Electrical Stimulation name each phase of a typical muscle twitch and on the following line. Describe what is happening in each phase. a) latent- is a short period between the time of stimulation and the beginning of contraction b). Contraction – at this stage the muscle reaches its peak in contraction. Relaxation -Muscle is shortened‚ returns to zero and back initial length.

TIME/DATE ___10/24/13__ Exercise 2 Skeletal Muscle Physiology The Muscle Twitch and the Latent Period 1. Define the terms skeletal muscle fiber‚ motor unit‚ skeletal muscle twitch‚ electrical stimulus‚ and latent period. Skeletal muscle fiber-fibers attached to the skeleton that produce muscle tension. Motor unit-consists of the motor neuron and all of the muscle fibers. Skeletal muscle twitch-mechanical response to a single action potential. Electrical stimulus-muscle contractions. Latent period-
