Question

List the structures of a sperm. (Module 26.3C) List the structures of a sperm. (Module 26.3C) acrosome, head, cilia, and flagella acrosome, head, neck, middle piece, and tail nucleus, lysosomes, peroxisomes, and Golgi apparatus acrosome, spermatid, and spermiogenic head head, neck, and tail

Answer 1

Answer:

head,acrosome, neck, middle piece, and tail

Explanation:

The sperm cells are sex cells that are produced in the testicular organ (gonad) of male human beings and animals.

The basic structure of the sperm includes;

1) The Sperm Head

A normal sperm head is smooth and oval shape, and measures 2.5 to 3.5 um in diameter and 4.0 to 5.5 um in length.

The head is the most important part of the cell given that it contains the nucleus which takes about 65% of the head and consist of the 23 chromosomes. Other materials too like the acrosomal region is found in the head which comprises of the acrosome and the acrosomal cap ( the acrosome is involved in the recognition of the oocyte (egg) to be fertilized).

2) The centriole is part of the sperm cell located between the head and the midpiece (the neck). In a centriole-centrosome complex, the centriole is involved in the formation of sperm aster and zygote aster.

3) Middle piece

The midpiece is the central part of the sperm cell between the head and the tail. They contain tightly packed mitochondria that provide the energy requires for swimming of the sperm towards the oocytes.

4)Tail

The sperm tail is a thin, elongated structure that makes up about 80 percent of the entire length of the sperm. It consists of several parts;

a) Connecting piece – it connects the flagellum to the sperm head

b) Midpiece - In some books, the midpiece is described as part of the tail. It contains mitochondria and thus provided the energy required for movement as explained above

c) Principal piece (axial filament) and

d) End piece

principal piece and the end piece of the tail help generate the waveform that allows for movement of the sperm cells.

Answer 2

Answer:

I think your question is poorly worded, just like all the parts are: a head and its flagellum, but within them we can distinguish several structures, which, in cephalad-caudal order (from head to tail, that is, from top down), son: acrosome, nucleus, membrane, neck, middle piece, tail and end piece.

Explanation:

Sperm are zygote cells that have half the genetic load, which is why when they join the ovum in fertilization, they form the complete genetics of the human.

In turn, the sperm has very efficient mechanisms for obtaining rapid energy, since they consume many ATP molecules when inoculating the ovum during fertilization.

They are formed by with the help of the sertoli cell, which sets the physiological state so that in the human testicle they are formed releasing in the male semen.
