The acrosome is an organelle that develops over the anterior (front) half of the head in the spermatozoa (sperm cells) of humans and many other animals. It is a cap-like structure derived from the Golgi apparatus. In placental mammals, the acrosome contains degradative enzymes (including hyaluronidase and acrosin). [1]

Definition: What is an Acrosome? The acrosome is one of the main components of a sperm cell overlying the nucleus. It's located on the anterior part of the sperm head where it serves a number of important roles related to fertilization. * Introduced in 1898 by Lenhossek, the term translates to apical body or tip body.

The acrosome is a membrane-bound organelle of Golgi apparatus origin, commonly located at the tip of the head of the mature spermatozoon, which contains a variety of enzymes and antigens required for fertilization.

The acrosome is a special kind of organelle with a cap-like structure that covers the anterior portion of the head of the spermatozoon. The acrosome is derived from the Golgi apparatus and contains digestive enzymes.

…a cap known as the acrosome, which contains enzymes that help sperm to enter an egg. Only one sperm fertilizes each egg, even though 300,000,000 to 400,000,000 sperm are contained in an average ejaculation. Each egg and sperm produced has slightly different genetic information carried in the chromosomes; this accounts… Read More

The acrosome is a structure attached to the nucleus of a mature spermatozoon (Fig. 2). The acrosome contains proteolytic enzymes which are released to dissolve zona pellucida proteins during fertilization.

acrosome A tiny sac or double membrane in the head of a SPERMATOZOON that contains the digestive enzymes needed to break down the protective cell membrane of the egg and allow penetration. Release of these enzymes is called the acrosome reaction.

The acrosome is a unique membranous organelle located over the anterior part of the sperm nucleus that is highly conserved throughout evolution. This acidic vacuole contains a number of hydrolytic enzymes that, when secreted, help the sperm penetrate the egg's coats.

The acrosome is a single exocytotic vesicle overlying the nucleus of most animal sperm.

The acrosome is the term used for the area of the sperm head that occupies the first two thirds of the total volume. The morphology of the acrosome consists of a vesicle derived from the Golgi complex, which is synthesized and assembled during the early stages of spermiogenesis, i.e., sperm formation.
