VBSC 421 Lab 17: Urogenital and
Endocrine Systems
Kidney (shark) - ANS-elongate, brownish, straplike organs lying against the dorsal body
wall
Pancreas (shark) - ANS-consists of two distinct lobes connected by an isthmus
- ventral lobes and dorsal lobe
- major mass of tissue in this gland is exocrine and concerned with production of
digestive enzymes and buffering fluid, released into the SI
- Clusters of endocrine tissue secrete hormones associated with carbohydrate
metabolism
Ovaries (shark) - ANS-female primary sex organs
- located dorsal to the liver
- produce hormones that stimulate and maintain sexual maturity and promote
reproductive behavior
Mesovarium (shark) - ANS-supporting mesentary for the ovaries
Oviduct (shark) - ANS-enable transport of ova or oocytes from the peritoneal cavity to
outside
Uterus (shark) - ANS-
Falciform ligament (shark) - ANS-attaches the cranial liver to the body wall
Cloaca (shark) - ANS-terminal opening of the reproductive tract
Testes (shark) - ANS-primary sex organs, occur dorsal to the liver, supported by the
*mesorchium*
- produce hormones that stimulate and maintain sexual maturity and promote
reproductive behavior
Mesorchium (shark) - ANS-supportive mesentary of the testes
Ductus deferens (vas deferens) (shark) - ANS-on ventral surface of the kidneys
, Claspers (shark) - ANS-male copulatory organs, also modified pelvic fins
Spine (shark) - ANS-holds clasper in place during copulation, on distal lateral surface
Siphon (shark) - ANS-saclike organs overlying the ventral surface of the pelvic fins,
water is pumped into these through the muscular movement of the fins
Dorsal groove (shark) - ANS-dorsal surface of the clasper- permits transfer of sperm
Kidneys (cat) - ANS-paired, *retroperitoneal*, surrounded by fat deposits in the dorsal
portion of the lumbar region
- right kidney is located slightly more posterior than the left because of the posterior
extension of the caudate lobe of the liver on the right side
Cortex (cat) - ANS-outer narrow band of lighter tissue
Medulla (cat) - ANS-central darker region (striated)
Papilla (cat) - ANS-vertex of the renal medulla
Renal pelvis (cat) - ANS-the expanded proximal end of the ureter (papilla opens into
this)
Ureter (cat) - ANS-tubes with muscular walls leading from the kidney to the urinary
bladder
- begins as the renal pelvis, courses posteriorly, and passes through lateral ligament of
the urinary bladder to enter the bladder
Urinary bladder (cat) - ANS-stores urine
Urethra (cat) - ANS-passage for urine to leave the bladder
Ovaries (cat) - ANS-primary reproductive organs of the female
Suspensory ovarian ligament - ANS-suspends ovaries *anteriorly* from dorsal body wall
