Where is the inferior mesenteric vein located?
The inferior mesenteric vein arises in the lower abdomen as a continuation of the superior rectal vein that drains the rectal (hemorrhoidal) venous plexus. The inferior mesenteric vein runs retroperitoneally, ascending from its origin to the left side.
What forms the inferior mesenteric vein?
The inferior mesenteric vein merges with the splenic vein, posterior to the middle of the body of the pancreas. The splenic vein then merges with the superior mesenteric vein to form the portal vein.
Where does the inferior mesenteric carry blood to?
The IMA supplies blood to the distal one-third of the transverse colon, descending colon and proximal two-thirds of the rectum.
Why is the cephalic vein in the arm?
The cephalic vein is a superficial vein of the upper limb and it’s one of the two main veins of the arm. Its name derives from ‘cephalic’ meaning head, as the vein runs up to the shoulder.

What does inferior mesenteric supply?
It supplies the distal third of the transverse colon, the splenic flexure, the descending colon, the sigmoid colon and the rectum, as well as the superior part of the anal canal down to the dentate line.
Where does the inferior mesenteric vein drain blood from?

What is the function of the inferior mesenteric?
The inferior mesenteric artery (IMA) brings oxygen-rich blood to the large intestine, specifically to the upper region of the rectum and the left colic flexure, a bend at the intestine’s left side.
What happens if inferior mesenteric artery is blocked?
In mesenteric ischemia, a blockage in an artery cuts off blood flow to a portion of the intestine. Mesenteric ischemia (mez-un-TER-ik is-KEE-me-uh) occurs when narrowed or blocked arteries restrict blood flow to your small intestine. Decreased blood flow can permanently damage the small intestine.
What’s the big vein in your arm called?
The cephalic vein stays at a superficial level as it runs up the arm over the biceps. At the top of the arm it lies between the deltoid and pectoralis major. The large vein crossing the front of the elbow is the antecubital vein. It crosses from the cephalic, to the basilic vein.
What vein is located in the arm?
The deep veins of the upper extremity include the paired ulnar, radial, and interosseous veins in the forearm; paired brachial veins of the upper arm; and axillary vein. The axillary vein originates at the lower border of the teres major muscle in continuity with the brachial veins.
What is the difference between superior and inferior mesenteric artery?
These organs are part of the digestive system. The artery branches off of the aorta, which is the body’s largest blood vessel. Superior refers to the artery’s location above other arteries that supply the intestines. A related artery, the inferior mesenteric artery, supplies the lower gastrointestinal (GI) tract.
What drains into inferior mesenteric vein?
The inferior mesenteric vein drains the mesenteric arcade of the hindgut (comprising of distal transverse, descending, and sigmoid colon). Specifically, it drains the tributaries of sigmoid veins, middle and left colic veins, as well as the superior rectal vein.
What are the symptoms of a blocked mesenteric artery?
Mesenteric artery ischemia occurs when there is a narrowing or blockage of one or more of the three major arteries that supply the small and large intestines. These are called the mesenteric arteries.
- Sudden severe abdominal pain or bloating.
What does SMAS pain feel like?
Symptoms may include abdominal pain, fullness, nausea, vomiting, and/or weight loss. SMAS typically is due to loss of the mesenteric fat pad (fatty tissue that surrounds the superior mesenteric artery). The most common cause is significant weight loss caused by medical disorders, psychological disorders, or surgery.
What are the 3 veins in the arm?
The most site for venipuncture is the antecubital fossa located in the anterior elbow at the fold. This area houses three veins: the cephalic, median cubital, and basilic veins (Figure 1).

What organs are supplied by the inferior mesenteric artery?
The inferior mesenteric artery, also a branch of the abdominal aorta, supplies the distal third of the transverse colon, the descending colon and sigmoid colon, and the superior portion of the rectum as the superior hemorrhoidal artery.
What does the mesenteric vein drain?
The superior mesenteric vein (SMV) is a large blood vessel in the abdomen. Its function is to drain blood from the small intestine as well as the first sections of the large intestine and other digestive organs. This large vein receives blood from several other veins (tributaries) in the digestive tract.
What does mesenteric ischemia pain feel like?
What are the symptoms of mesenteric ischemia? The main symptom of this condition is severe abdominal pain. The pain is usually in the middle or upper part of the abdomen at first, and then generalizes. If chronic, the pain usually starts within an hour after eating.
What is nutcracker syndrome?
Nutcracker syndrome is a rare vein compression disorder. It occurs when arteries, most often the abdomen’s aorta and superior mesenteric artery, squeeze the left renal (kidney) vein. It can cause many symptoms in both children and adults, such as flank pain and blood in the urine.
Which body part of the patient is at risk for superior mesenteric artery syndrome?
Superior mesenteric artery (SMA) syndrome is a condition that affects the duodenum — the section of the small intestine that joins the stomach.
Why is it hard to find a vein in my arm?
Veins can be difficult for a variety of reasons. Some people are genetically predisposed to having problematic veins, or their age causes the veins to be smaller or hidden. In most instances, however, it is a matter of the patient being dehydrated.
