artery,

blood vessel that conveys blood away from the heartheart,
muscular organ that pumps blood to all parts of the body. The rhythmic beating of the heart is a ceaseless activity, lasting from before birth to the end of life. Anatomy and Function

The human heart is a pear-shaped structure about the size of a fist.

. Except for the pulmonary artery, which carries deoxygenated blood from the heart to the lungs, arteries carry oxygenated blood from the heart to the tissues. The largest arterial trunk is the aortaaorta
, primary artery of the circulatory system in mammals, delivering oxygenated blood to all other arteries except those of the lungs. The human aorta, c.1 in. (2.54 cm) in diameter, originates at the left ventricle of the heart.

, microscopic blood vessel, smallest unit of the circulatory system. Capillaries form a network of tiny tubes throughout the body, connecting arterioles (smallest arteries) and venules (smallest veins).

, the latter connecting with the veinsvein,
blood vessel that returns blood to the heart. Except for the pulmonary vein, which carries oxygenated blood from the lungs to the heart, veins carry deoxygenated blood. The oxygen-depleted blood passes from the capillaries to the venules (small veins).

). Other important arteries are the subclavian and brachial arteries of the shoulder and arm, the carotid arteries that lead to the head, the coronary arteries that nourish the heart itself, and the iliac and femoral arteries of the abdomen and lower extremities. The walls of the large arteries have three layers: a tough elastic outer coat, a layer of muscular tissue, and a smooth, thin inner coat. Arterial walls expand and contract with each heartbeat, pumping blood throughout the body. The pulsating movement of blood, or pulsepulse,
alternate expansion and contraction of artery walls as heart action varies blood volume within the arteries. Artery walls are elastic. Hence they become distended by increased blood volume during systole, or contraction of the heart.

In the present study, middle meningeal artery and its branches were chosen due to the relevance for the generation of headaches (1,6), therefore the change in diameter of middle meningeal artery and its branches in response to mast cell degranulation in the dura mater has demonstrated that mast cells in the dura mater play a key role in the pathophysiology of migraine.
For instance, in an experimental study, it was shown that while AS19, selective 5-HT7 receptor agonist, increased blood flows of the middle meningeal artery following electrical stimulation of dura mater, 5-HT1B/1D receptor agonist sumatriptan decreased it (2).
In the present study, this vasodilation of middle meningeal artery and its anterior and posterior branches may be caused by vasodilator molecules released from mast cells such as histamine, NO, VIP, CGRP, and vascular endothelial growth factor.
Panoramic view of the dissection of the left infratemporal fossa showing the origin of the accessory meningeal artery (AMA) from the middle meningeal artery (MMA).
Closer view of the dissection of the left infratemporal fossa showing the origin of the accessory meningeal artery (AMA) from the middle meningeal artery (MMA) Note the two roots of auriculotemporal nerve (ATN) looping around it.
The supraorbital part of the stapedial artery forms in addition extraocular intraorbital arteries, the intracranial part of the middle meningeal artery. After the intraorbital branches of the stapedial artery are assimilated by the ophthalmic artery its proximal intra and retro orbital branches involute and become reabsorbed by the intracranial segment of the middle meningeal artery.
The middle meningeal artery may partially (only the anterior division) or completely arise from ophthalmic artery.
Ramus superior persists into adulthood as the intracranial part of middle meningeal artery. Wible (1987) recognized anterior and posterior divisions of the ramus superior.
GROSS ANATOMY AND CLINICAL CORELATION: The vessels passing through the superior orbital fissure and the cranioorbital foramen contribute to arterial supply of anterior part of dura of middle cranial fossa and form anastomoses between ophthalmic artery and middle meningeal artery or dural branches of internal carotid artery.
Orbital branches of middle meningeal artery passing through cranioorbital foramen is thought to be main vascular supply to meningiomas in the anterior cranial fossa as indicated by Kuru (1967).
An anastomosis between middle meningeal artery and recurrent meningeal branch of lacrimal artery was found to be usual.
