Seminiferous Tubules function

Site of germ cell development

Leidig Cells function

AKA Interstitial cells. Secrete Testosterone

Sertoli Cells function

AKA Sustentacular cells. Supplies nutrients to developing sperm. Secrete inhibin

Spermatids function

Immature derivatives of germ cells. Develop and mature to become sperm

Testes features

Seminiferous tubules, Leidig cells, Sertoli cells, Spermatids

Ovary features

Primordial follicles, developing (primary and secondary) follicles, Tertiary (Grafian) follicle, corpus luteum

Primordial follicles function

Ova paused in meiosis, surrounded by a single layer of support cells.

Developing (primary and secondary) follicles function

Support cells become cuboidal and multiply as the ova continues through meiosis and the follicle gets larger

Tertiary (Grafian) follicle function

Largest developed follicle capable of undergoing ovulation

Corpus luteum function

Remnant of a follicle shortly after ovulation

Seminiferous tubules

Leidig cells

Sertoli cells

Spermatids

Primordial follicles

Developing (primary and secondary) follicles

Tertiary (Grafian) follicles

Corpus luteum

Testis function

Sperm production; secretes androgen hormones

Seminiferous Tubules function

within testis, site of sperm production

Epididymis function

site of sperm maturation between seminiferous tubules and ductus deferens

Ductus (vas) deferens function

transports sperm

cremaster muscle function

elevates the scrotum

Penis features

glans penis, prepuce, corpora cavernosa, corpus spongiosum

male urethra

Scrotum features

testis, seminiferous tubules, epididymis

Spermatic cord features

ductus (vas) deferens, cremaster muscle

accessory glands features

seminal gland, prostate gland, bulbourethral gland

seminal gland function

secretes 60% of semen volume

prostate gland function

secretes 30 % of semen volume

bulbourethral gland function

secretes alkaline lubricating fluid

site of implantation of fertilized ovum

cervix

vagina function

muscular tube (birth canal)

ovaries

corpora cavernosa

bulbs of the vestibule

Testes and ovaries

Homologous structures that produce gametes

Skin of the scrotum and labia majora

Homologous structures that often develop coarse hair during puberty

Skin of penis shaft and labia minora

Homologous structures that do not develop coarse hair

Glans penis and glans clitoris

Homologous structures that is the tip of structure containing nerve endings

Prepuce and prepuce

Homologous structures that is the skin covering glans organ

Corpora cavernosa and corpora cavernosa

Homologous structures that are the two cylinders of erectile tissue

Corpus spongiosum and bulbs of vestibule

Homologous structures that are one tube of erectile tissue, divided in two for females
