Question
muscles of the thigh exhibit gross movements for walking. Therefore, you would find (large or small) The units in the thigh. How is muscle tone maintained in the muscle? If the nerve to a muscle is cut, what will happen to the musele? The Muscular System: Contraction of Whole Musele 1. Which of the following contract in an all or none fashion? a. Whole muscle b. Single muscle fiber of tension in a muscle, in response to a stimulus above threshold, is called a 3. Identify the three phases of a muscle twitch from the following definitions: a. Sarcomeres shorten b. Sarcomeres return to resting length c. Sarcomeres at resting length a. Temporal summation results from: b. In temporal summation, you must ( stimuli. Below is a list of the five phases of temporal summation. Put in the correct order and describe each stage. 4. Tor4) the time interval between Description Order S Sta Fatigue Incomplete tetanus Treppe Complete tetanusExplanation / Answer
Answer 6:
Muscle tone is maintained by the impulses sent from Brain through cranial nerves and also impulses sent from Spinal nerves.
If the nerve to a muscle is cut then it will lead to Paralysis and muscle atrophy would occur.
Answer 1: The choice is:
b) Single Muscle fibre contract in an all or none fashion.
Answer 2:
The development of tension in a muscle, in response to stimulus above threshold is called a Muscle Twitch.
Answer 3:
a) Sarcomeres shorten in contraction phase.
b) Sarcomeres return to resting length in Relaxation Phase.
c ) Sarcomeres is at resting length at Latent Phase.
Answer 4:
a) Temporal summation results from second stimulus which is applied before complete relaxation.
b) In Temporal summation, you must decrease the time interval between stimuli.
Answer 5:
There is rapid cycles but some relaxation are also seen
Correct Order Stage Description 4 Fatigue Due to decrease in ATP, Tension is decreased. There is increase of Lactic acid. 2 Incomplete TetanusThere is rapid cycles but some relaxation are also seen
1 Treppe Due to warming there is increased tension and there is increase in enzyme efficiency. 3 Complete Tetanus There is sustained smooth contraction.Related Questions
