To define these terms used in describing muscle physiology: multiple motor unit summation‚ maximal stimulus‚ treppe‚ wave summation‚ and tetanus. 2. To identify two ways that the mode of stimulation can affect muscle force production. 3. To plot a graph relating stimulus strength and twitch force to illustrate graded muscle response. 4. To explain how slow‚ smooth‚ sustained contraction is possible in

Earthworm Smooth Muscle In this experiment‚ contractions of the earthworm gut are measured in an organ bath with a force transducer. The effect of neurotransmitters and ionic concentrations on contraction strength and rate will be investigated. Written by staff of ADInstruments With acknowledgement to: Dr. Stuart I.

4) Rehabilitation Plan Days 1 to 5 | RICE protocol - rest‚ ice‚ compression and elevation (as said before never apply ice directly to the skin). The Hamstring should be rested in an elevated position with an Ice Pack applied for twenty minutes every two hours‚ if practical (never apply ice directly to the skin). A Compression Bandage should be applied to limit bleeding and swelling in the tissues. After the early stages have been spent resting‚ more active rehabilitation can be started. |

UNIT 2 As soon as you begin to exercise changes begin to happen within your body. Body systems work together‚ to make sure that you have enough energy to perform. Body systems respond both in the Short and Long-term in response to exercise. It is important to understand the changes that happen to the body as a result of physical activity. You will understand the: Muscoskeletal‚ Cardiovascular and Respiratory responses to exercise through this unit As soon as you begin to exercise changes begin

What .is the role of acetylcholine in a skeletal muscle contraction? Skeletal muscle fiber-Skeletal muscle fibers are the individual cells that are bound together in fascicles. Many fascicles are bound together to make a muscle Motor unit-A motor unit consists of a motor neuron and all of the muscle

Aerobic Exercises During Pregnancy Each workout or exercise session should consist of three parts: a warm-up period‚ the aerobic workout‚ and a cool-down period. The Warm-Up Don’t neglect this. No aerobic workout should be started on a "cold" body. Warm-up moves signal your body that more vigorous activity is coming and prevent injury by releasing muscle tension and making the body more flexible. Spend a minimum of five minutes (ten minutes is much better) stretching and limbering up. Stretch
