Trace the path of sperm from its formation in the seminiferous tubules up to ejaculation.

Releasing of sperms from seminiferous tubules is known as.

The process of release of spermatozoa from Sertoli cells into cavity of the seminiferous tubules is called

Release of sperms from seminiferous tubules is called

Trace the path of sperm during ejaculation and mention the gland and their functions associated with the male reproductive system.

Assertion : Formation of sperm takes place in seminiferous tubules of testes . Reason : Seminiferous tubules lined with male germ cells and sertoli cells (a) If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion . (b) If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion. (c) If Assertion is True but the Reason is False . (d) If both Assertion & Reason are False. .

Which is the correct pathway of sperms. (i) Epididymis (ii) Seminiferous tubules (iii) Vas - efferentia (iv) Rete-testis

Go through the following statements:- (i). Primary spermatocytes undergo mitotic divisions to produce secondary spermatocytes (ii). Sperms released from the seminiferous tubules are fuly mature and motile (iii) The head of sperm possesses may mitochondria which produce energy for the movement of tail (iv) The human male ejaculates about 20-30 million sperms during a coitus which of these are correct?

Read the following statements about male reproductive system and identify the correct ones. I . The scrotum helps in maintaining the temperature ideal for spermatogenesis . II. The male germ cells present in the seminiferous tubules undergo mitotic division and lead to the formation of sperms . III . The bulbourethral glands secrete substances which help in lubricating the penis and these glands also help in formation of the ejaculatory duct. IV. The site of spermatogenesis are highly compartments of the testis .

A right-angle crown glass prism with critical angle 41^(@) is placed berore an object, PQ , in two position as shown in the figure (i) and (ii) . Trace the paths of the rays from P and Q passing through the prism in the two cases.
