Spermiation and Spermiogenesis

Q.

What is spermatogenesis? Briefly describe the process of spermatogenesis.

Q.

Define spermiogenesis and spermiation.

Q.

Spermiation is the process of the release of sperms from:

1. Epididymis

2. Vas deferens

3. Prostate gland

4. Seminiferous tubules

Q.

Why does spermatogenesis result in four spermatids but oogenesis only in one ovum?

Q. Choose the incorrect statement with respect to physiology of mature sperms.

1. Sperms present in epididymis for 18-24 hours develop capacity of motility
2. Average velocity of sperms through the fluid may be 1-4mm/minute
3. Strong acidic medium can cause rapid death of sperms
4. Most of the energy for sperm motility is derived from the lipids present in the seminal fluid

Q.

Spermiation is the process of the release of sperms from______

1. vas deferens

2. seminiferous tubules

3. epididymis

4. prostate gland

Q. The difference between spermiogenesis and spermiation is

1. In spermiogenesis spermatozoa from sertoli cells are released into the cavity of the seminiferous tubules, while in spermiation spermatozoa are formed
2. In spermiogenesis spermatozoa are formed, while in spermiation spermatids are formed
3. In spermiogenesis spermatids are formed, while in spermiation spermatozoa are formed
4. In spermiogenesis spermatozoa are formed, while in spermiation spermatozoa are formed released from sertoli cells in to the cavity of seminiferous tubules

Q. ‘Spermiogenesis’ refers to–

1. Formation of spermatids
2. Metamorphosis of spermatids into sperms
3. Phase of multiplication of spermatogenesis
4. Growth phase of spermatogenesis

1. Head Region: Caput epididymis
   Body region: Corpus epididymis
   Tail region: Cauda epididymis

2. Head Region: Caput epididymis
   Body region: Cauda epididymis
   Tail region: Corpus epididymis

3. Head Region: Cauda epididymis
   Body region: Caput epididymis
   Tail region: Corpus epididymis
4. Head Region: Corpus epididymis
   Body region: Cauda epididymis
   Tail region: Caput epididymis

Q. What is spermiogenesis?

1. Spermiogenesis is another name for the process of puberty.
2. Spermiogenesis is the sequence of events that leads to the production of spermatids.
3. Spermiogenesis is the reabsorbing of sperms that are not ejaculated.
4. Spermiogenesis is the conversion of spermatids to spermatozoa.

Q. Spermiogenesis is induced by factors released by:

1. Sertoli cells
2. Spermatogonia
3. Primordial germ cell
4. Gonadotroph cells

Q.

Spermiation is the process of the release of sperms from______

1. seminiferous tubules

2. vas deferens

3. epididymis

4. prostate gland

Q.

In the testes, the sperms are formed by

1. Nephrons

2. Graafian follicles

3. Seminiferous tubules

4. Interstitial cells

Q.

How do spermiogenesis differ from spermiation?

Q. Which of the following is true for spermiogenesis?

1. Spermatids are transformed into sperms in this process
2. Sperms are released from the seminiferous tubules in this process
3. Spermatogenesis is one of the steps in spermiogenesis
4. It is the process of formation of male germ cells

Q. What is the correct sequence of sperm formation?

1. Spermatid - spermatocyte - spermatogonia - spermatozoa
2. Spermatogonia - spermatocyte - spermatozoa - spermatid
3. Spermatogonia - spermatozoa - spermatocyte - spermatid
4. Spermatogonia - spermatocyte - spermatid - spermatozoa

Q.

WHAT IS THE SIGNIFICANCE OF SPERMATOGENESIS & OOGENESIS?

Q. In spermatogenesis, the phase of maturation involves

1. The formation of spermatogonia from genocytes through mitosis.
