PATHOLOGY

Detailed explanation-1: -The acrosome is present at the anterior end of the elongated nucleus in the sperm head as the cap-like structure. It contains proteolytic enzymes such as hyaluronidase and acrosin that help the sperm in penetrating the ovum through the zona pellucida layer around the ovum and enter the cytoplasm of the ovum.

Detailed explanation-2: -It is a cap-like structure derived from the Golgi apparatus. 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.
