1

List the order of spermatogenesis

Spermatogoinium-->primary spermatocyte-->secondary spermatocyte-->spermatids

2

What is the tunica albunginea

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

3

What is the pathway of sperm?

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

4

Myoid cells

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

5

Rete testes

Where the seminiferous tubules converge

6

TEX14

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

7

Spermatogonia

Stem cells committed to meiosis

8

Primary spermatocytes

Diploid, 4C

9

Secondary spermatocytes

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

10

Spermatids

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

11

Spermatozoa

Early spermatids undergo spermiogenesis to become spermatozoa
