Reproductive system

Bordered by the ischial tuberosities & coccyx

Anal triangle

Serous-fluid filled cavity surrounding an oocyte

Antrum

Small external female erectile tissue, abundant nerves & blood supply

Clitoris

If no pregnancy, white scar tissue remnant of an ovarian follicle forms

Corpus albicans

Secretes estrogen & progesterones; yellow body follicle remnant after ovulation

Corpus luteum

Skeletal muscle of the spermatic cord that elevates the testes

Cremaster

Superficial smooth muscle that can wrinkle the scrotal skin

Dartos

Tip of the penis, very sensitive, may be covered by a foreskin

Glans

Incomplete, thin partition of the distal vaginal mucosa

Hymen

Hole in anterior abdominal wall to allow passage of spermatic cord

Inguinal canal

Collections of alveoli in the breast produce milk (lactation)

Lactiferous lobule

Milk leaves this structure and then the nipple while nursing

Lactiferous sinus

Stratum functionalis breaks down and is shed during menstruation

Menstrual phase

Venous network of the testes, makes up part of the spermatic cord

Pampiniform plexus

Follicle with an oocyte surrounded by cuboidal epithelium

Primary follicle

Follicle with an oocyte surrounded by simple squamous epithelium

Primordial follicle

Occurs with secondary & vesicular follicles; endometrium thickens

Proliferative phase

Abnormal (and often asymptomatic) uterine position within the pelvis

Retroverted

Follicle with an oocyte and new zona pellucida and corona radiata

Secondary follicle

Endometrium is at its thickest; corpus luteum & albicans

Secretory phase

Spermatocytes + testicular fluid + accessory gland secretions

Semen

Cylindrical region of the penis connecting the glans to the root

Shaft

Runs through the inguinal canal carrying vessels, nerves, muscles

Spermatic cord

Deeper layer of the endometrium, does not change through uterine cycle

Stratum basalis

Superficial layer of the endometrium, changes over the uterine cycle

Stratum functionalis

Oxygenated blood is delivered through these via the spermatic cord

Testicular artery

Bordered by the ischial tuberosities & pubic symphysis

Urogenital triangle

Oocyte with large antrum immediately prior to ovulation

Vesicular follicle

**most primitive follicle type**

\
\n **primodial follicle**

**single layer of cuboidal cells (follicle)**

**primary follicle**

**oocyte with small antrum**

secondary follicle

**secondary oocyte, many layers of follicular cells, large antrum**

vesicular follicle
