Q

Excitation Definition for Muscle Contraction

A

Neurotransmitters bind to receptor sites on the motor end plate to cause an impulse that travelers through the T tubules into the Sarcoplasmic Reticulum (SR) that releases calcium ions that travel through the sarcoplasm into the sarcomeres.

Q

Contraction Definition for Muscle Contraction

A

Calcium ions come into contact with the actin within the sarcomeres that stimulates the proponents and tropomyosin to expose myosin binding. Myosin attaches to the actin (cross bridging) and creates a power stroke. This action is continually repeated as long as ATP and calcium ions are present.

Q

Anaerobic glycosis

A

During muscle fatigue, the body can convert glycogen to glucose
First Stage:
- Oxygen is not used
- Starts really quick and ends within 30-60 sec
- Produces lactic acid
- lactic acid can be converted to glucose
- oxygen is used (heavy breathing) to process lactic acid

Q

Aerobic Glycosis

A

During muscle fatigue, the body can convert glycogen to glucose
Second Stage:
- uses oxygen to produce the same as 36 ATP molecules
- expels carbon dioxide through mitochondrial cellular respiration
- continues as long as oxygen is available.

Q

All-or-none Response

A
  • after a nerve impulse begins, it will be conducted at maximum capacity, without fluctuations in membrane potential and without any decrease in magnitude
  • if the stimulus is sufficient, the muscle fibers associated with the motor unit will contract to their fullest extent

Q

Pain Spasm Pain Cycle

A
  • The cycle of responses in the muscle fibers that continues unless intervened on my external force such as massage or ice bath
  • Cycle:

    > increase tissue damage by decreased blood and oxygen supply
    > Tissue Injury
    > Nociceptor Activation
    > Pain stimulus to spinal cord
    > stimulus to brain
