Explanation / Answer
1) The given statement is true.
The four behavioural characteristics of skeletal muscle tissue include:
Irritability.
Extensibility.
Elasticity.
Contractility.
2) The given statement is true.
Muscle contractions produce heat approx. 70% of body heat. It is produced by energy generated in skeletal muscle tissue.
3) The given statement is false.
The fixator in a movement is the muscle. They provide an essential support to assist to hold the rest of the body.
4) The given statement is true.
A muscle with several central tendons toward which the muscle fibers converge known as multipennate muscle. Deltoid muscle is an example of multipennate muscle.
