Histology of the Male Reproductive System

Question 1

Male role of reproductions

Answer 1

Produce sperm and deliver to female

Question 2

Whats the role of male gonads?

Answer 2

Endocrine - produce testosterone

Exocrine - produce sperm

Question 3

What are the gonads outside the body?

Answer 3

Temperature of the scotum is 34 C, which is more efficient for sperm
Sperm are nonfuncitonal at 37 C (body temp)

Question 4

What are the steps of Spermatogeneis

Answer 4

Spermatocytogenesis

Spermigenesis

Question 5

Spermatocytogenesis

Answer 5

Formation of spermatogonia to spermatocytes to spermatids

Question 6

Spermigenesis

Answer 6

Maturation process - spermatids to spermazoa

Question 7

What are the intersticular ducts?

Answer 7

Straight tubules
Rete testis
Efferent ductules

Question 8

What are the Straight tubules?

Answer 8

Short, straight tubules
Lined only with Sertoli cells
At the very end, switch to cuboidal epithelium with underlying dense connective tissue

Question 9

Rete Testis

Answer 9

Interconnected network of channels lined with cuboidal epithelium or low columnar epithelium with underlying dense CT

Question 10

Efferent ductules

Answer 10

Lined with pseudostratified columnar epithelium with groups of nonciliated cuboidal cells with microvilli alternating with groups of taller ciliated cells, some circularly oritented smooth muscle cells can be found around these

Question 11

Female role in reproductions

Answer 11

Production of eggs

Providing locations for fertilization and embryonic development

Question 12

Role of Female gonads

Answer 12

Endocrine - produce estrogens and progestogens

Exocrine - Produce female gamete (ovum), and produce and ovulate a secondary oocyte

Question 13

Estrogen

Answer 13

Growth
maturation of reproduction organs
cyclic changes in uterine mucosa

Question 14

Uterine tube cell type

Answer 14

Simple Columnar epithelium

Question 15

What are the 3 layers of the Uterus

Answer 15

Perimetrium
Myometrium
Endometrium

Question 16

Perimetrium

Answer 16

Outer connective tissue layer of uteru

Question 17

Myometrium

Answer 17

Middle and thickest layer of uterus

Bundles of smooth muscle connected by connective tissue containing blood vessels

Question 18

Endometrium

Answer 18

Inner layer of Uterus

2 parts: basal layer, functional layer

Question 19

Seminal vesicles

Answer 19

Highly torturous glands rich in secretory granules

Joins with ampulla of ductus defrens to form ejaculatory duct

Question 20

Prostate gland

Answer 20

Collection of 30-50 tubuloalveolar glands embedded in a dense fibromuscular stroma
Empties into prostatic urethra

Question 21

Bulbourethral glands

Answer 21

Compound tubuloalveolar glands

Empty into the proximal part of the penile urethra

Question 22

Corpus Cavernosa

Answer 24

Primordial Follicles
Growing Follicles
Mature follicles

Question 25

What are the 2 parts of the Theca folliculi

Answer 26

Theca interna

Theca externa

Question 27

Theca interna

Answer 27

Suboidal secretory cells that act in response to LH

Synthesize and excrete andorgens

Question 28
