Question

In the given cross section of testis, identify the labelled parts and match them with their relative description given alongside.
i. Storage area for the sperm

ii. Carry the sperm from the testes to the epididymis

iii. Has germinal and sertoli cells

• A. 1 - iii, 2 - i, 3 - ii
• B. 1 - iii, 2 - ii, 3 - iii
• C. 1 - ii, 2 - i, 3 - iii
• D. 1 - i, 2 - ii, 3 - iii

Answer 1

The correct option is D 1 - i, 2 - ii, 3 - iii

1- Epididymis
2- Efferent ducts
3- Seminiferous tubules

Each testicular lobule houses 2 to 3 coiled tubules running through each of these lobules known as the seminiferous tubules. These tubules have 2 kinds of cells - sertoli cells and cuboidal germinal cells which undergo various stages of differentiation to form sperm. The sperm formed here leaves the lobule through the rete testis which opens into ductules called the efferent ducts (vasa efferentia). The efferent ducts lead to the epididymis where sperms are stored.
