• Muscle atrophy is when muscles waste away.

• The main reason for muscle wasting is a lack of physical activity. This can happen when a disease or injury makes it difficult or impossible for you to move an arm or leg.

• Capacitation is an activation process that involves both enhancement of flagellar activity and the biochemical and structural changes in the plasma membrane of the sperm head that prepares sperm to undergo the acrosomal reaction.

• Spermatozoa are first activated by capacitation when they enter the uterus to permit better swimming.

• As they approach the egg or ovum they then undergo the acrosome reaction to permit penetration of the zona pellucida, the shell of the ovum.
