Explanation / Answer

Question 1

Answer E (Elasticity)

Elasticity indicates the ability of the muscle to recoil after being stretched.

contractility is the ability of the muscle to generate force to cause contraction.

conductivity is the ability of the muscle to transmit the electrical stimulus through the muscle.

extensibility is the ability of the muscle to stretch.

Question 2

Answer E (all of the above)

i. blood circulation

ii. preventing the body from falling over

iii. urination

iv. maintenance of body at 37 degrees centigrade

Question 3

Answer C (cardiac muscle)

These are involuntary, mononucleated and striated muscles

Question 4

answer C (Endomysium)

The connective tissue covering each muscle fiber is called endomysium.

Question 5

Answer C (Dystrophin)

The contractile proteins of muscle are Actin, myosin, troponin, and tropomyosin.
