Pig Dissection 4-7 Flashcards
In the mediastinum enclosed by the pericardium
Heart
An oval, reddish organ (gland) at the base of the throat
Thyroid
A large, brownish elongated mass of tissue extending over the heart and superior thoracic organs
Thymus
Flank the heart
Lungs
Abdominal cavity organs include:
Liver, stomach, spleen, small intestine, large intestine, and urinary bladder
A large, brown multilobed organ posterior to the diaphragm that dominates the abdominal cavity
Liver
To the left of and nearly covered by the liver
Stomach
A brown organ curving around the lateral aspect of the stomach
Spleen
Continues posteriorly from the stomach
Small intestine
Also called the spiral colon, a large compact mass of dark coils lying within the coils of the small intestine
Large intestine
The large saclike structure seen attached to and entering the umbilical cord in the lower abdominal wall
Urinary bladder
The first abdominal branch of the aorta diverging from the aorta immediately as it enter the abdominal cavity. It’s branches supply the stomach, liver, gallbladder, pancreas, and spleen
Celiac trunk (artery)
Emerges from the central surface of the abdominal aorta; supplies the small intestine and most of the large intestine
Superior mesenteric artery
Paired arteries diverging from the aorta slightly posterior to the anterior mesenteric artery; supply the muscles of the body wall and the adrenal glands
Adrenolumbar arteries
Large paired arteries arising from the aorta posterior to the adrenolumbar arteries and coursing to the kidneys, which they supply
Renal arteries
Slender paired arteries serving the gonads
Gonadal arteries (testicular/ovarian)
Thin unpaired vessel arising from the ventral surface of the aorta posterior to the gonadal arteries; supplies the 2nd half of the large intestine and rectum
Inferior mesenteric artery
Large arteries that issue from the lateral surface of the aorta and continue through the body wall, passing under the inguinal ligament to enter the thigh
External iliac arteries
Veins of the thorax and upper limb include:
Costocervical trunks, internal thoracic veins, right/left brachiocephalic veins, internal jugular vein, external jugular vein, and subclavian vein
Paired veins entering the superior vena cava just before it enters the heart, receive blood from 3 veins.
Costcocervical trunks
Enters the superior vena cava at the level of the 3rd rib, drains the ribs and mammary glands
Internal thoracic veins
Form the superior vena cava by their union
Right and left brachiocephalic veins
Drains the deeper regions of head
Internal jugular vein
Lateral to the internal jugular vein; drains the superficial tissues of the head
External jugular vein
