Male Histology

Question 1

List the order of spermatogenesis

Answer 1

Spermatogoinium–>primary spermatocyte–>secondary spermatocyte–>spermatids

Question 2

What is the tunica albunginea

Answer 2

Dense fibrous capsule that surrounds the testis. Its interlobular septa divides the testes into 250 pyramidal compartments/testicular lobules

Question 3

What is the pathway of sperm?

Answer 3

Testis (seminiferous tubules)–>rete testis–>efferent ducts–>epididymis–>vas deferens–>ejaculatory duct (joins with seminal vesc–>prostate–>urethra

Question 4

Myoid cells

Answer 4

Smooth muscle-like cells that adhere to the basal lamina and help propel the sperm from the seminiferous tubules to the rete testis

Question 5

Rete testes

Answer 5

Where the seminiferous tubules converge

Question 6

TEX14

Answer 6

Must be present in order for developing spermatogonia to remain connected to each other by cytoplasmic bridges.

Question 7

Spermatogonia

Answer 7

Stem cells committed to meiosis

Question 8

Primary spermatocytes

Answer 8

Diploid, 4C

Question 9

Secondary spermatocytes

Answer 9

Primary undergo meiosis I to produce secondary (haploid, 2C)

Question 10

Spermatids

Answer 10

Secondary undergo meiosis 2 to produce spermatids (haploid, 1C)

Question 11

Spermatozoa

Answer 11

Early spermatids undergo spermiogenesis to become spermatozoa
