A
17
Q

What is the function of the cremaster muscle?

A

Elevate the testes; derivative of the internal oblique

18
Q

What is the function of the dartos muscle?

A

Smooth muscle that wrinkles scrotal skin

19
Q

Label the following parts of the testes:

seminiferous tubules, epididymis, efferent ductules, rete testis, tubulus rectus

A
20
Q

Label the following cell types of spermatogenesis:

Spermatogonia, primary spermatocyte, early spermatid, intermediate spermatid, late spermatid, Sertoli cells, myoid cell, fibroblast

A
21
Q

Describe the seminal vesicles. Size? Location? Product?

A

Shape and size of little finger

attached to posterior bladder

produces viscous seminal fluid (70% of semen volume)

Duct empties into vas deferens (forms ejaculatory duct)

22
Q

Describe the prostate. Size and shape? Secretions? Function?

A

Size and shape of peach pit

Secretes a milky fluid that activates sperm; 1/3 of semen volume

23
Q

Describe the bulbourethral gland. Size and shape? Location? Function?

A

Pea-sized glands inferior to the prostate

Prior to ejaculation, produces thick, clear mucus that lubricates glans penis and neutralizes traces of urine

24
Q

Label the following parts of the penis:

Corpora cavernosa, corpora spongiosum, tunica albuginea, urethra, superficial dorsal vein, deep dorsal vein, dorsal artery, urethral glands, erectile tissue

A
25
Q

A
26
Q

Label the following aspects of the ovary:

Primordial follicle, oocyte, germinal epithelium, cuboidal follicle cells, zona pellucida

A
27
Q

What is this structure?

A
29
Q

What is the stratum functionalis?

A

Functional layer of the endometrium; changes in response to hormone cycles; shed during menstration

30
Q

What is the stratum basalis?

A

Basal layer of the endometrium; forms new functionalis layer after menstruation

31
Q
