NAME Rachel Brockhuis LAB TIME/DATE _______________________ 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. Motor unit- single α-motor neuron and all of the corresponding muscle fibers it innervates; all of these fibers will be of the same type Skeletal muscle fiber- long and narrow cells that often span the entire length of a muscle Skeletal muscle

Russian Sport Protocol April 8‚ 2010 Dysfunctions: - Stress fractures in right and left tibia bones . Client has tenderness and pain (usually in the lower 1/3 quadrant of the tibia) if pressure is applied. The stress fracture is probably caused by long‚ tough workouts‚ without much rest‚(soccer) causing the muscles ( Tibialis Anterior)to fatigue. My goal of this session is to increase blood flow‚ circulation‚ tissue/muscle regeneration and decrease muscle tension‚ fatigue and pain in that

Exercise 2: Skeletal Muscle Physiology: Activity 3: The Effect of Stimulus Frequency on Skeletal Muscle Contraction Lab Report Pre-lab Quiz Results You scored 100% by answering 4 out of 4 questions correctly. 1. During a single twitch of a skeletal muscle You correctly answered: b. maximal force is never achieved. 2. When a skeletal muscle is repetitively stimulated‚ twitches can overlap each other and result in a stronger muscle contraction than a stand-alone twitch. This phenomenon is known as

Muscle tissue Muscle tissue has a ability to relax and contrast and so bring about movement and mechanical work in various parts of the body. There are other movements in the body too which are necessary for the survival of the organism such as the heart beat and the movements of the alimentary canal. Muscles can be divided into three main groups according to their structure * Smooth muscle tissue. * Skeletal muscle tissue. * Cardiac (heart) muscle tissue.

During an isometric contraction You correctly answered: d. the skeletal muscle is generating force‚ but it remains at a fixed length. 2. The force that results from muscles being stretched is You correctly answered: a. passive force. 3. Active force You correctly answered: b. is

Lab 3 – Skeletal Muscle Physiology Introduction Skeletal muscles are composed of hundreds to thousands of individual cells‚ each doing their share of work in the production of force. As their name suggests‚ skeletal muscles move the skeleton. Skeletal muscles are remarkable machines; while allowing us the manual dexterity to create magnificent works of art‚ they are also capable of generating the brute force needed to lift a 100-lb. sack of concrete. When a skeletal muscle from an experimental

THOMPSON‚ a 60 year old marathon runner and chief of cardiology at Hartford Hospital‚ stood in front of a medical audience recently and began his talk with a story about himself. Hes had been lifting weights since he was 12 years old. Dr. Thompson is now a small and wiry with not a bulging muscle on him. He was speculated that he must have a genetic inability to build muscles‚ no matter how hard he works at it. But
