Muscle, Smooth, Vascular
Muscle, Smooth, Vascular

The nonstriated, involuntary muscle tissue of blood vessels.

Tunica Media
Tunica Media

The middle coat of blood vessel walls, composed principally of thin, cylindrical, smooth muscle cells and elastic tissue. It accounts for the bulk of the wall of most arteries. The smooth muscle cells are arranged in circular layers around the vessel, and the thickness of the coat varies with the size of the vessel.

Myocardium
Myocardium

The muscle tissue of the HEART. It is composed of striated, involuntary muscle cells (MYOCYTES, CARDIAC) connected to form the contractile pump to generate blood flow.

Papillary Muscles
Papillary Muscles

Conical muscular projections from the walls of the cardiac ventricles, attached to the cusps of the atrioventricular valves by the chordae tendineae.

Myocytes, Cardiac
Myocytes, Cardiac

Striated muscle cells found in the heart. They are derived from cardiac myoblasts (MYOBLASTS, CARDIAC). Myoblasts, Cardiac; Myofibrils;

Blood-Air Barrier
Blood-Air Barrier

The barrier between capillary blood and alveolar air comprising the alveolar EPITHELIUM and capillary ENDOTHELIUM with their adherent BASEMENT MEMBRANE and EPITHELIAL CELL cytoplasm. PULMONARY GAS EXCHANGE occurs across this membrane.

Blood-Nerve Barrier
Blood-Nerve Barrier

The barrier between the perineurium of PERIPHERAL NERVES and the endothelium (ENDOTHELIUM, VASCULAR) of endoneurial CAPILLARIES. The perineurium acts as a diffusion barrier, but ion permeability at the blood-nerve barrier is still higher than at the BLOOD-BRAIN BARRIER. Capillary Permeability;

Blood Vessels
Blood Vessels

Any of the tubular vessels conveying the blood (arteries, arterioles, capillaries, venules, and veins).

Arteries
Arteries

The vessels carrying blood away from the heart.

Bronchial Arteries
Bronchial Arteries

Left bronchial arteries arise from the thoracic aorta, the right from the first aortic intercostal or the upper left bronchial artery; they supply the bronchi and the lower trachea.

Carotid Artery, Common
Carotid Artery, Common

The two principal arteries supplying the structures of the head and neck. They ascend in the neck, one on each side, and at the level of the upper border of the thyroid cartilage, each divides into two branches, the external (CAROTID ARTERY, EXTERNAL) and internal (CAROTID ARTERY, INTERNAL) carotid arteries.

Carotid Artery, External
Carotid Artery, External

Branch of the common carotid artery which supplies the exterior of the head, the face, and the greater part of the neck.

Carotid Artery, Internal
Carotid Artery, Internal

Branch of the common carotid artery which supplies the anterior part of the brain, the eye and its appendages, the forehead and nose.

Cerebral Arteries
Cerebral Arteries

The arterial blood vessels supplying the CEREBRUM.

Circle of Willis
Circle of Willis

A polygonal anastomosis at the base of the brain formed by the internal carotid (CAROTID ARTERY, INTERNAL), proximal parts of the anterior, middle, and posterior cerebral arteries (ANTERIOR CEREBRAL ARTERY; MIDDLE CEREBRAL ARTERY; POSTERIOR CEREBRAL ARTERY), the anterior communicating artery and the posterior communicating arteries.

Temporal Arteries
Temporal Arteries

Arteries arising from the external carotid or the maxillary artery and distributing to the temporal region.

Anterior Cerebral Artery
Anterior Cerebral Artery

Artery formed by the bifurcation of the internal carotid artery (CAROTID ARTERY, INTERNAL). Branches of the anterior cerebral artery supply the CAUDATE NUCLEUS; INTERNAL CAPSULE; PUTAMEN; SEPTAL NUCLEI; GYRUS CINGULI; and surfaces of the FRONTAL LOBE and PARIETAL LOBE.

Middle Cerebral Artery
Middle Cerebral Artery

The largest of the cerebral arteries. It trifurcates into temporal, frontal, and parietal branches supplying blood to most of the parenchyma of these lobes in the CEREBRAL CORTEX. These are the areas involved in motor, sensory, and speech activities.

Posterior Cerebral Artery
Posterior Cerebral Artery

Artery formed by the bifurcation of the BASILAR ARTERY. Branches of the posterior cerebral artery supply portions of the OCCIPITAL LOBE; PARIETAL LOBE; inferior temporal gyrus, brainstem, and CHOROID PLEXUS.

Ciliary Arteries
Ciliary Arteries

Three groups of arteries found in the eye which supply the iris, pupil, sclera, conjunctiva, and the muscles of the iris.
