Anatomy Q3
Veins
| Definition | Term |
|---|---|
| brain drainage | dural sinuses |
| digestive system drainage | hepatic portal system |
| returns blood from body regions superior to the diaphragm | superior vena cava |
| returns blood from body regions inferior to the diaphragm | inferior vena cava |
| empty into the right atrium | superior & inferior vena cava |
| superior & inferior sagittal sinuses, straight sinus, transverse sinuses, sigmoid sinus | dural sinuses |
| drain most of the blood of the brain | dural sinuses |
| empty into the internal jugular veins | dural sinuses |
| s-shaped sigmoid sinuses become the ____ ____ veins | internal jugular |
| located between the layers of cranial dura mater | dural sinuses |
| veins of the head & neck | internal jugular veins, external jugular veins, vertebral veins |
| superiorly, lies lateral to the internal carotids, and inferiorly, lies lateral to the common carotids | internal jugular veins |
| at the base of the neck, the internal jugular veins joins with the ____ vein to from the ____ vein | subclavian; brachiocephalic |
| descends through the neck on the surface of the SCM | external jugular veins |
| superiorly, its tributaries drain the posterior scalp, lateral scalp, and some of the face | external jugular veins |
| are not accompanied by any corresponding artery | external jugular veins |
| empty into the subclavian vein | external jugular veins |
| unlike the ___ arteries, the ____ veins do not serve much of the brain | vertebral |
| draining the cervical vertebrae, cervical spinal cord, and muscle in the superior neck region | vertebral veins |
| originating inferior to the occipital condyle, each vertebral vein descends through the transverse foramina of vertebrae C1-C6 in the form of s venous plexus | vertebral veins |
| exit from C6 as a single vein, continue inferiorly to join the brachiocephalic vein in the root of the neck | vertebral veins |
| follow the paths of companion arteries; have the same names as the companion arteries | deep veins of the upper limbs |
| superficial veins are larger than the deep veins | upper limbs |
| visible beneath skin, frequent anastomoses | superficial veins of the upper limbs |
| superficial veins of the upper limbs | cephalic, basilic, median cubital, median vein of the forearm |
| starts at lateral side of the dorsal venous network, bends around the distal radius to enter the anterior forearm. then, this vein ascends through the anterolateral side of the entire limb & ends inferior to the clavicle, where it joins the axillary vein | cephalic vein |
| arises from the medial aspect of the hand's dorsal venous network, then ascends along the posteromedial forearm and the anteromedial surface of the arm. in the axillary region, this vein joins the brachial vein to become the axillary vein | basilic vein |
| on the anterior aspect of the elbow joint, in the region called the antecubital fossa, this vein connects the basilic & cephalic veins | median cubital vein |
| often used for a blood draw or IV line | median cubital vein |
| ascends in the center of the forearm; its termination point at the elbow is highly variable | median vein of the forearm |
| blood draining from the first few intercostal spaces empties into the ___ veins | brachiocephalic |
| blood draining from the other intercostal spaces drains into a group of veins called the ____ ____ | azygos system |
| drains intercostal spaces; empties into the superior vena cava; comprised of azygos vein, hemiazygos vein, & accessory hemiazygos vein | azygos sytem |
| name means unpaired | azygos vein |
| ascends along the right or the center of the thoracic vertebral bodies | azygos vein |
| receives all of the right posterior intercostal veins, plus the subcostal vein | azygos vein |
| at about the level of T4, the ____ arches over the great vessels that run into the root of the right lung and joins the superior vena cava | azygos vein |
| ascends on the left side of the vertebral column, corresponds to the inferior half of the azygos on the right | hemiazygos vein |
| at about midthorax, the ___ runs horizontally across the vertebrae and joins the azygos vein | hemiazygos vein |
| superior continuation of the hemiazygos; course along the right to join the azygos vein | accessory hemiazygos vein |
| blood returning from the _____ _____ and the ____ wall reaches the heart via the inferior vena cava | abdominopelvic viscera; abdominal |
| most venous tributaries of this great vein share the names of the corresponding arteries | inferior vena cava |
| the right & left ___ veins exit the liver superiorly and empty into the most superior part of the inferior vena cava | hepatic |
| these veins carry all the blood that originated in the digestive organs in the abdominopelvic caivty and arrived via the ____ portal system | hepatic |
| a specialized part of the vascular circuit | hepatic portal system |
| picks up digested nutrients from the stomach and intestines and delivers these nutrients to the liver for processing and storage (ditto for toxins) | hepatic portal system |
| series of vessels in which two separate capillary beds lie between the arterial supply and the final venous drainage | hepatic portal system |
| share the same name of the accompanying artery | deep veins of the pelvis & lower limbs |
| empties into the femoral vein | great saphenous vein |
| superficial veins of the pelvis & lower limbs | great saphenous vein & small saphenous vein |
| longest vein in the body | great saphenous vein |
| ascends along the medial side to empty into the femoral vein just distal to the inguinal ligament | great saphenous vein |
| empties into the popliteal vein | small saphenous vein |
| runs along the lateral side of the foot and then along the posterior calf | small saphenous vein |
| posterior to the knee, it empties into the popliteal vein | small saphenous vein |
| multivein bundles | venous plexuses |
