Question 10

why are testes located in the scrotum

Answer 10

outside of the body because lower temp in required for sperm production , 34C

b. )primary spermatocytes
c. ) secondary spermatocytes
d. ) spermatids

Question 14

spermatozoa move from seminiferous tubules to

Question 15

intratesticular ducts are;

__;short straight tubules, lined only with sertoli cells, at very end switch to cuboidal epithelium with underlying dense connective tissue

Answer 15

straight tubules

Question 16

intratesticular ducts are;

interconnected network of channels lined with cuboidal epithelium or low columnar epithelium with underlying dense connective tissue, epithelial cells have a single apical cilium and a few short apical microvilli

Answer 16

rete testis

Question 17

leave the testes and enter head of epididymis, lined with pseudostratified columnar epithelium with groups of nonciliated cuboidal cells with microvilli alternating with groups of taller ciliated cells

Answer 17

efferent ductules

Question 18

highly coiled, lined with pseudostratified columnar epithelium composed of rounded basal cells and columnar cells with stereocilia (known as principal cells) surrounded by smooth muscle, 4-5 meters in length, storage and completion of maturation process occurs here

Answer 18

ductus epididymis

Answer 23

spongy/penile urthrea

Question 24

2 highly tortuous tubular glands lined with simple columnar epi or pseudostratified columnar and outer longitudinal arrangement. thin folds seen in lumen to increase secretory surface area, joins with ampulla of ducts deferens to form ejac duct

Answer 24
