LAST AP1 LAB PRACTICUM

gonads

testes and ovary

seminiferous tubules

site of germ cell development

Leidig cells

AKA Interstitial cells. Secrete testosterone

Sertoli Cells

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

Spermatids

immature derivatives of germ cells, develop and mature to become sperm

Features of Testes

seminiferous tubules, leidig cells, sertoli cells, spermatids

ovary features

primordial follicles, developing (primary and secondary) follicles, tertiary (grafian) follicle, corpus luteum

primordial follicles

ova paused in meiosis, surrounds by a single layer of support cells

developing (primary and secondary) follicles

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

tertiary (grafian) follicle

largest developed follicle capable of undergoing ovulation

corpus luteum

remnant of a follicle shortly after ovulation

scrotum

testis, seminiferous tubules, epididymis

Testis (testes)

sperm production; secretes androgen hormones

seminiferous tubules

within testis; site of sperm production

epididymis

site of sperm maturation between seminiferous tubules and ductus deferens

spermatic cord

ductus (vas) deferens and cremaster muscle

ductus (vas) deferens

transports sperm

cremaster muscle

elevates the scrotum

penis

glans penis, prepuce, corpora cavernosa, corpus spongiosum

glans penis

rounded head (tip) of the penis, containing many sensory neurons

prepuce

commonly called the foreskin

corpora cavernosa

two erectile tissue

corpus spongiosum

single erectile tissue that surrounds urethra

accessory glands

seminal gland, prostate gland, bulbourethral gland

seminal gland

secretes 60% of semen volume

prostate gland

secretes 30% of semen volume

bulbourethral gland

secretes alkaline lubricating fluid

ovaries

production of ova (eggs) and estrogens

uterine (Fallopian) tubes

connect ovary with uterus

fimbriae

finger-like projections, distal end

uterus

site of implantation of fertilized ovum

cervix

narrow, inferior region that secretes mucus vagi

vagina

muscular tube (birth canal)

vulva

external genitalia

vulva

labia majora, labia minora, external urethral orfice, prepuce, greater vestibular glands, hymen

labia majora

singular: labium major

labia minora

singular: labium minus

external urethral orifice

opening of the urethra to the external world (where urine leaves the body)

prepuce

skin covering the glans clitoris, often called the “clitoral hood”

greater vestibular glands

secrete lubricating fluid into the vagina

hymen

epithelial tissue that may temporarily obstruct the vagina in some individuals

clitoris

erectile tissue with sensory nerves

clitoris

glans clitoris, corpora cavernosa, bulbs of the vestibule

glans clitoris

anterior-most tip of the clitoris, containing nerve endings

corpora cavernosa

two erectile tissues, can be up to 7 cm long in an adult

bulbs of the vestibule

two bodies of erectile tissue, homologous to the corpus spongiosum split in two

homologous structure that produce gametes

testes, ovaries

homologous structure that often develop coarse hair during puberty

skin of scrotum, labia majora

homologous structure that do not develop coarse hair

skin of penis shaft, labia minora

homologous structure; tip of structure containing nerve endings

glans penis, glans clitoris

homologous structure, skin covering glans organ

prepuce, prepuce

homologous structure; two cylinders of erectile tissue

corpora cavernosa, corpora cavernosa

homologous structure that, one tube of erectile tissue, divided in two for females

corpus spongiosum, bulbs of vestibule

scrotum

testis (testes)

epididymis

spermatic cord

ductus (vans) deferens

cremaster muscle

penis

glans penis

corpora cavernosa

corpus spongiosum

prostate gland

seminal gland

ovaries

uterine (fallopian) tubes

fimbriae

uterus

cervix

vagina

labia majora

labia minora

external urethral orifice

clitoris

bulbs of vestibule

glans clitoris

corpora cavernosa
