Q. What is the function of anal sphincter?
Q. Why do we get muscle cramp after vigorous exercise?​

Answer 1

Answer:

Definition of 'periodicity'

1. the tendency, quality, or fact of recurring at regular intervals. 2. Chemistry. the occurrence of similar properties in elements occupying similar positions in the periodic table.

(2)The external anal sphincter is composed of skeletal muscle that functions like other postural muscles in the body. It is a voluntary muscle that responds to volitional commands to contract and maintain continence when feces are propelled through a relaxed internal anal sphincter into the rectum.

(3)Muscle cramps occur when there is anaerobic respiration taking place in our muscles. During anaerobic respiration, glucose gets converted into lactic acid which leads to lack of oxygen. A hot water bath or a massage can help in getting relief from the muscle cramps
