How to draw the structure of sperm | labelled diagram of sperm -abhishek educare
In this video I'm going to draw the structure of sperm labelled diagram which is an important diagram for the class 12
Hope this will help you...
structure of sperm :
Sperm is the male gamete. It is a motile,
microscopic elongated cell. It is divisible into
three parts- head, middle piece and tail.
contains hydrolytic enzymes; hyaluronidase
and proteolytic enzymes like zona lysins and
corona penetrating enzymes.
Neck: It is a very short region having two
centrioles i.e. proximal centriole and distal
centriole.
Middle piece: It has an axial filament
surrounded by 10-14 spiral turns of
mitochondria (nebenkern). It produces energy
necessary for the movement of sperm.
Tail: It is a long, slender and tapering part
containing cytoplasm and fine thread- axial
filament. The axial filament arises from the
distal centriole and travels through out the
length of tail. It is partly surrounded by plasma
membrane (main piece). The part without
plasma membrane is called end piece.
