brachiocephalic artery
The brachiocephalic artery is the first major branch off of the aortic arch, it gives rise to the right internal carotid artery and the right subclavian artery. The brachiocephalic artery is also sometimes called the brachiocephalic trunk, and may also be called the innominate artery.

Right arm: right subclavian artery --> rt. brachial A --> rt radial or ulnar A --> palmar digital A Rt. head can be divided into brain, skull, facial structures Which is very complex As a rule, the carotid supplies all the head and neck region The internal branch supplies the brain tissue: e.g. middle cerebral artery. The vertebral branch of the subclavian a. supplies the bain as well via the basillar A. The external branch gives off 7 main branches, supplying the neck and head organs, bones EXCEPT the brain
The are two paired arteries that supply the head. You have the carotid arteries (where you take your pulse in the neck). There are also paired vertebral arteries that run up through the transverse foramen in the cervical vertebrae.
The aortic arch is the area in which the aorta bends in order to descend into the body. It also gives way to three major blood vessels. Thus, the "functions" of the aortic arch are:To bend back the main vessel in order to reach the part of the body below the heart itself;To give off 3 major arteries: the brachiocephalic artery, left common carotid artery, left subclavian artery.
The Brachial artery on the inside of the elbow is most commonly used because it can be accessed easily and compressed with a cuff. However it does depend on what method you are using. With use of sphygmomanometer (inflated cuff compresses artery) you can use the brachial or the radial (at the wrist - the same as commonly used for taking the pulse). This gives less reliable results. (Some monitors even use the digital arteries in the finger). Invasive methods in which the pressure is measured directly by passing a sensor into directly the artery are often used during surgical or invasive procedures. In such cases larger deeper seated arteries are used (eg Subclavian - behind the collarbone or femoral - in the groin) as well as the brachial or radial arteries.
The subclavian passes below the clavicle, becoming the axillary artery. The axillary artery gives rise to the brachial artery. The brachial is the largest artery in the arm, and spits into three major branches the profunda brachii in the arm , and the radial and ulna arteries in the forearms. Other arteries include the interosseous, circumflex, and humeral nutrient arteries.
Temporal artery has twocomponents. One is a superficial temporal artery is a terminal branch of external carotid. It divides into two parts and it's pulsations can be felt on Temporal bone above the Zygomatic arch.. It divides into anterior and posterior branches. They supply the temple and scalp. Anterior branch anastomoses with the supra-orbital branch of ophthalmic artery, which is a branch of Internal carotid. It also gives the transverse facial branchsupplying the face. Deep temporal is a branch of second part of maxillary artery. It supply the temporal muscle, a muscle of mastication.

They branch off from the right coronary artery which arises from the aorta.
There are three places in the body to get an accurate pulse. The femoral artery in the thigh, the radial artery in the wrist, or the carotid artery in the neck. The radial and carotid arteries are closer to the surface of the skin and thus are easier to get a pulse from.
The small intestine has 3 parts: duodenum, jejunum, and ileum. The large intestine starts on the right with the ascending colon proceeds across the body as the transverse colon and then goes down on the left side of the body as the descending colon. The descending colon becomes the sigmoid colon. The rectum and anal canal follow. The celiac trunk gives off the common hepatic artery, which branches into the proper hepatic artery and the gastroduodenal artery. The gastroduodenal artery gives off the supraduodenal, retroduodenal, anterior and posterior superior pancreaticoduodenal arteries. These 4 arteries supply the duodenum. The superior mesenteric artery branches into several different arteries. The anterior and posterior pancreaticoduodenal arteries supply the duodenum. Intestinal arteries have a complex network of arcades that feed the jejunum and ileum. The ileocecal artery off the SMA gives off branches to the terminal ileum and the cecum. The right colic artery supplies the ascending colon. The inferior mesenteric artery branches into the middle colic artery, which supplies the transverse colon; the left colic artery, which supplies the descending colon; the sigmoid artery, to the sigmoid colon; rectosigmoid artery, in between the rectum and the sigmoid colon; superior rectal artery, to the uppermost part of the rectum.
