What is the first branch of the internal carotid artery?

How do I trace blood from the ascending aorta to the lower right first molar?

The first thing is to determine what artery provides blood to the lower right first molar. The lower teeth sit in the mandible and are supplied by branches of the The major artery in the mandible supplying the teeth is the inferior alveolar artery, which sends branches to supply the roots of each tooth (including the first molar) in the lower jaw. Next is to find the origin of the inferior alveolar artery and work backwards until we get to the ascending aorta. The inferior alveolar artery is a branch of the internal maxillary artery, which itself is a branch of the external carotid artery. The external carotid artery is a branch of the common carotid artery. So far everything has been symmetrical, so it hasn't mattered whether we specified that the artery was on the right or the left side. But the common carotid arteries behave a little differently. The right common carotid is a branch of the innominate artery, which branches from the aortic arch. The left common carotid artery branches directly from the aortic arch. Since we're concerned with the lower right first molar, we'll work backwards from the right common carotid, innominate artery, and aortic arch. The last bit is just to know that the aortic arch is an extension of the ascending aorta. With that, we're done. Now we just sew the whole thing together, artery by artery, in the reverse order: Ascending aorta -> aortic arch -> innominate artery -> right common carotid artery -> right external carotid artery -> right internal maxillary artery -> right inferior alveolar artery -> branch to lower right first molar.

What is the vessel called that branches to form a right common carotid and right subclavian?

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.

What is the correct sequence of the branching of the aortic arch?

The first branch of the Aortc Arch is the BRACHIOCEPHALIC ARTERY, which divides into the right common catotid artery, which transports blood to the right side of the head and neck, and the right subclavian artery, which transports blood to upper right limb. The second branch of the Aortic Arch is the left common carotid artery, which divides intothe left internal carotid artery that supplies the brain and the left external carotid artery that supplies muscles and the skin of the neck and head. the third branch of the Aortic Arch Is the Left subclavian artery, which branches in to the vertebral artery that supplies parts of the brain. In the axillary are of the body, the subclavian artey is know as the axillary artery, which continues down the arm as the brachial artery. Near the elbow joint divides into the radial and ulnar arteries, which supply the forearm.

What artery flows into right subclavian?

The brachiocephalic trunk is the first artery to branch off from the aorta. This then bifurcates (splits into two) creating the right subclavian and right common carotid arteries

Which arteries originates as the first branch of the subclavian artery?

The first branch of the subclavian artery is the vertebral artery. It arises from the posterior aspect of the subclavian artery and ascends through the cervical vertebrae to supply blood to the brain and spinal cord. Other important branches of the subclavian artery include the internal thoracic artery and the thyrocervical trunk, but these originate after the vertebral artery.

Is the pedis artery the first major branch of the femoral artery?

No

What is the first major branch of renal artery?

The first major branch of the renal artery is the Renal hilius The answer is actually interlobar

First blood vessels to branch from aorta?

That would be the Carotid arteries.

Is there an ileum artery?

No, but there is are two common iliac arteries (branches of the abdominal aorta). The common iliac arteries then divide into internal and external iliac arteries.

What is the first arteries to branch off from the aorta?

Well um.... there are a few more than just one I'll list them all.... coronary Arteries; the brachiocephalic artery; left common carotid artery; left subclavian artery; oesophageal artery; right and left bronchial artery; mediastinal artery; poterior intercostal arteries; subcostal arteries; inferior phrenic artery, celiac trunk artery, middle suprarenal artery; superior mesenteric artery; renal artery; 1st through 4th lumbar arteries; and finally the artery bifurcates.
