Structure of human spermatozoon, Biology

Structure of human spermatozoon:

Nature: Human sperms are minute, microscopic and motile.
Structure: Each sperm have an oval shaped head piece, a neck, a middle piece and a long tail.
Head piece : An oval head piece consists of a large haploid nucleus. In addition to this, a sac like structure called acrosome is present in the head piece which helps in fertilization.
Neck: The neck is short and connects the head with the middle piece.
Middle piece: It lies between head and tail middle piece is large and tubular and has several mitochondria, which produce energy required for movements of sperms.
Tail piece: Tail piece is long and helps in swimming of sperms to reach ovum during fertilization.
Life span - Sperms live for a period of 24 to 72 hours.
