Acrosome

Definition of the noun acrosome

What does acrosome mean as a name of something?

noun - plural: acrosomes

  1. a process at the anterior end of a sperm cell that produces enzymes to facilitate penetration of the egg

Alternative definition of the noun acrosome

noun

  1. A structure forming the end of the head of a spermatozoon.

Explanation

  1. The acrosome is an organelle that develops over the anterior half of the head in the spermatozoa of many animals. It is a cap-like structure derived from the Golgi apparatus. Acrosome formation is completed during testicular maturation. In Eutherian mammals the acrosome contains digestive enzymes. These enzymes break down the outer membrane of the ovum, called the zona pellucida, allowing the haploid nucleus in the sperm cell to join with the haploid nucleus in the ovum.
    • also known as 顶体
  2. acrosome is a gene ontology group, gene group.
