Acrosome
Acrosome
Acrosome (/ˈækrəˌsoʊm/) is a cap-like structure present on the head of a spermatozoon. It is derived from the Golgi apparatus in the spermatid (the immature sperm cell during the process of spermatogenesis).
Etymology
The term "acrosome" is derived from the Greek words "akros" meaning "at the top" and "soma" meaning "body".
Function
The acrosome contains enzymes (such as hyaluronidase and acrosin) that help the sperm cell to penetrate the outer layers of the egg cell during fertilization.
