Anatomy II: Lesson 13 FEMALE UROGENITAL SYSTEM

OBJECTIVE: STUDENTS WILL INVESTIGATE THE FEMALE UROGENITAL SYSTEM IN

ORDER IDENTIFY THE ANATOMICAL STRUCTURES AND VARIANTS AMONGST SPECIES.

Warm Up:

Which specie does

this penis belong to?

Hint: It has a very

large ampulla gland

Which species have a

fibroelastic penis?

Infundibulum (Funnel around)

Fimbrae (diverging processes)

Abdominal Ostium

Uterine tube (oviduct or salpinx)

Suspended by mesosalpinx

Uterine Horn

Ligaments and Bursa

Broad Ligament:

Ovaries and uterine tubes are suspended within the mesovarium and mesosalpinx which are the cranial parts of this ligament

Suspensory Ligament:

Forms the cranial portion of the free border of the broad ligament

Proper Ligament:

Continuation of the suspensory ligament caudally which attaches to the apex of the uterine horn

Ovarian Bursa:

Mesovarium, mesosalpinx and proper ligament of the ovary enclose a small peritoneal cavity
