Dissection 8 Ids

Front 1

Abdominal Sympathetic Trunk

Back 1

Lateral to Abdominal Aorta, Medial to Psosas Major, lines the vertebral bodies.

Front 2

Celiac Ganglion

Back 2

Located above the celiac trunk.

Front 3

celiac plexus

Back 3

efferent fibers of celiac ganglion (post-ganglionic fibers).

Front 4

central tendon of the diaphragm

Back 4

aponeuosis of posterior abdominal wall muscles (including diaphragm) that converge at the posterior surface of the diaphragm.

Front 5

cortex of the kidney

Back 5

the perforated outer surface of the kidney. The perforations represent the corpuscles.

Front 6

Crura of the diaphragm (left and right crus of diaphragm)

Back 6

Medial portions of the diaphragm muscle through which the abdomdinal aorta and thoracic duct emerge. Their tendons seem to emerge from the anterior longitudinal ligament of the vertebral bodies.

Front 7

greater thoracic splanchnic nerve

Back 7

Sympathetic fibers originating from T5-T9 of the sympathetic trunk. They emerge superior and lateral to the celiac trunk through the crura of the diaphragm. They synapse with the pre-vertebral celiac ganglion.

Front 8

Hiatuses in diaphragm for the inferior vena cava, esophogus
and aorta.

Back 8

Venal hiatus is in the right portion of the diaphragm central tendon. esophagus hiatus defines the superior portion of the diaphragm cura and the aortic hiatus emerges at the inferior portion of the crura.

Front 9

inferior phrenic artery

Back 9

Branches superior to the celiac trunk.

Front 10

Lumbar arteries

Back 10

Arteries that branch laterally from the aorta. These would be intercostal arteries but since there are no ribs, they are lumbar arteries.

Front 11

Lumbar splanchnic nerves

Back 11

unable to find

Front 12

major calyces

Back 12

Part of the collecting system of the kidney once the urine has been produced. They form from the joining of the minor calyces that are at the tips of the renal pyramids.

Front 13

Medulla of Kidney

Back 13

Deep the denser interior region of the kidney. The other and inner medulla compose the renal pyramids.

Front 14

Minor Calyces

Back 14

Initial connection to the tips of the renal pyramids of the medulla.

Front 15

Ovarian Arteries

Back 15

Lateral and inferior to the superor mesenteric artery but superior to the inferior mesenteric artery.

Front 16

psoas major muscle

Back 16

Interior most muscle that flank the lumbar vertebral column. Ligaments appear to be attached to the lateral sides of the vertebral bodies.

Front 17

psoas minor muscle

Back 17

sits anteriorly on the psoas major muscle. Has a tendon that extends inferiorly to the end of the posterior endge pecten pubis (where the pectineal ligament runs)

Front 18

quadratus lumborum muscle

Back 18

lateral to the psoas major muscle on the posterior abdominal wall.

Front 19

renal artery and its segmented branches

Back 19

renal arteries and veins branch directly from the abdominal aorta at the level of the superior mesenteric artery.

The renal artery branches to a superior anterior and inferior branch. The anterior branch bifurcates into a superior and inferior branch. These branches then become interlobar arteries, then arcuate arteries, and finally interlobular arteries. arcuate (structure have a bow or curved like outline).

Front 20

Renal papilla

Back 20

The tip of the renal pyramid that interfaces with the minor calyx. (calyx is a cup shaped organ or cavity).

Front 21

Renal Pelvis

Back 21

The final and largest part of the collecting system of the kidney before the urine enters the ureter for excretion. The major calices flow into the renal pelvis.

Front 22

Renal Pyramids

Back 22

These are the substructures of the medulla that contain the ascending and descending thick and thin limbs of the nephron as well as the collecting duct and loops of henle.

Front 23

Renal Sinus

Back 23

Sinus posterior to the renal pelvis and major calices. Usually filled with fat.

Front 24

Renal Vein

Back 24

Branches off the inferior vena cava. The left renal vein is longer than the right because the inferior vena cava is to the right of the aorta.

Front 25

Suprarenal arteries (superior, middle, and inferior).

Back 25

Suior and middle branches come directly from the abdominal aorta. The superior branches as soon as the abdominal aorta emerges from its hiatus and the middle branches at the level of the celiac trunk. The inferior artery branches from the renal artery at a proximal location.

Front 26

Suprarenal vein

Back 26

The renal vein branches supriorly into the phrenic vein and suprarenal vein. The suprarenal vein terminates at the suprarenal gland (adrenal).

Front 27

Testicualar/Ovarian Artery and Vein

Back 27

The left vein branches inferiorly from the renal vein while the right vein branches from the IVC inferior to the renal vein.

The right and left artery branch lateral and inferior to the superior mesenteric artery with the right artery more inferior.

Front 28

Ureter

Back 28

The The renal pelvis flows into the ureter which extends inferiorly to the bladder.

Front 29

Vagus nerves along the lesser curvature of the stomach

Back 29

Follows both the anterior and posterior sides of the lesser curvature.
