Figure 7. Diagram of the human spermatozoon
The spermatozoon (spermatozoid) is a man’s gamete which produced in testis
The spermatozoid consists of 3 main components:
-the head
-the neck
-the tail
The tail is subdivided into three segments:
-the middle piece
-the principal piece
-the end piece
There is a nucleus in the head. The nucleus involves a very condensed chromatin. The acrosomal cap surrounds the anterior two-thirds of the nucleus.
Acrosome contains different hydrolytic and mucolytic enzymes. The enzymes disaggregate the cells of the corona radiata and dissolve the zona pellucida during fertilization.
There are two centrioles in the neck. The tail consists of axoneme and a lot of mitochondrias.
