Which of the following statements are correct about the structure of a sperm?

• [A.] It is composed of head, thorax, neck and tail.
• [B.] The neck region contains a lot of mitochondria.
• [C.] The mitochondria produce energy for the movement of the tail.

Select the correct sequence of events in human spermatogenesis:

• [(A)] Spermatid
• [(B)] Spermatogonia
• [(C)] Spermatozoa
• [(D)] Secondary Spermatocytes
• [(E)] Primary Spermatocytes

Spermatogenesis starts at the age of puberty due to a significant increase in secretion of Gonadotropin Releasing Hormone (GnRH). Increased levels of GnRH stimulate the secretion of two gonadotropins which are:

A pregnant female was admitted to the labour room. Mild uterine contractions started, but further strong uterine contractions were not taking place. Which of these could a doctor inject to induce delivery?

A primary spermatocyte after first meiotic division leads to the formation of secondary spermatocytes. These are:

Which among the following hormones is not produced by placenta?

Arrange the following events in correct sequence:

• [A.] Formation of zygote
• [B.] Formation of blastocyst
• [C.] Implantation
• [D.] Formation of morula

Select the correct statement/s from the following:

• [A.] Spermatogonia always undergo meiotic cell division.
• [B.] Primary spermatocytes divide by mitotic cell division.
• [C.] Secondary spermatocytes have 23 chromosomes and undergo second meiotic division.
• [D.] Spermatozoa are transformed into spermatids.

In the following statements, identify the stages of oogenesis in the order in which they occur:

• [(A)] During fertilisation, formation of egg and second polar body.
• [(B)] Meiosis II commences but stops at metaphase II.
• [(C)] Meiosis I commences but stops at prophase I.
• [(D)] Formation of primary oocyte from oogonia.
• [(E)] Meiosis I completes and results in formation of secondary oocyte and first polar body.

Which of the following hormones is not produced by the placenta?
