Cerebral cortex The cerebral cortex is gray matter, consisting mainly of cell bodies (with astrocytes being the most abundant cell type in the cortex as well as the human brain as a whole) and capillaries.It contrasts with the underlying white matter, consisting mainly of the white myelinated sheaths of neuronal axons.he layered structure of the mature cerebral cortex is formed during development. The first pyramidal neurons generated migrate out of the ventricular zone and subventricular zone, together with reelin producing Cajal–Retzius neurons, from the preplate.

Arteries of the Brain The basilar artery is so-named because of its close relationship to the base of the skull. Arteries of the brain supply blood to the brainstem, cerebellum, and cerebrum, and those arteries will be discussed in relation to these brain regions after describing the circle of Willis. Recommended video: Meninges of the brain. Meninges and superficial vessels of the brain.

Overview The vertebrobasilar arterial system perfuses the medulla, cerebellum, pons, midbrain, thalamus, and occipital cortex. Occlusion of large vessels in this system usually leads to major disability or death. Vertebrobasilar stroke carries a mortality rate of more than 85%.

- Vertebral artery. The vertebral arteries are among the major arteries of the neck. Part of the vertebrobasilar system, these arteries are responsible for supplying blood to the brain stem portion of the human brain, which helps control basic functions such as breathing, heart rate, and sleeping. The vertebral artery can be divided into four parts.

Blood Vessels of the Brain At the base of the brain, the carotid and vertebrobasilar arteries form a circle of communicating arteries known as the Circle of Willis. From this circle, other arteries—the anterior cerebral artery (ACA), the middle cerebral artery (MCA), the posterior cerebral artery (PCA)—arise and travel to all parts of the brain.Posterior Inferior Cerebellar Arteries (PICA), which branch from the vertebral arteries, are not shown.he vertebrobasilar arteries supply the posterior two-fifths of the cerebrum, part of the cerebellum, and the brain stem. Any decrease in the flow of blood through one of the internal carotid arteries brings about some impairment in the function of the frontal lobes.

Chapter 12 - The Nutrition of the Brain Chapter 12 - The Nutrition of the Brain. Circulation of the brain. There are four arteries supplying the brain (figure 35). The two carotid arteries and their branches comprise the anterior circulation and the two vertebral arteries comprise the posterior circulation. There are small penetrating blood vessels that come off the larger vessels.

- Inside the brain, there are four cavities, called ventricles. The right and left lateral ventricles and the third and fourth ventricles compose the ventricular system. The fourth ventricle contains cerebrospinal fluid. It has a diamond shape and is located in the upper portion of the medulla.

Blood Vessels of the Brain At the base of the brain, the carotid and vertebrobasilar arteries form a circle of communicating arteries known as the Circle of Willis. From this circle, other arteries—the anterior cerebral artery (ACA), the middle cerebral artery (MCA), the posterior cerebral artery (PCA)—arise and travel to all parts of the brain.ormal function of the brain’s control centers is dependent upon adequate supply of oxygen and nutrients through a dense network of blood vessels. Blood is supplied to the brain, face, and scalp via two major sets of vessels: the right and left common carotid arteries and the right and left vertebral arteries.

What is the Circle of Willis? The Circle of Willis is a ring or circle of arteries located at the base of the brain. The arteries in the Circle of Willis may be enough to preserve blood flow to the brain even if one artery is constricted or blocked.he Circle of Willis is a ring or circle of arteries located at the base of the brain.

All the output of blood from the left side of the heart goes into the aorta, the body’s largest artery. Other arteries branch from the aorta to supply blood to the head, limbs, and internal organs. The blood is drained from all these parts by veins into two large vessels, the inferior and superior venae cava, which deliver the blood back to the right side of the heart.

Heart Anatomy set 1 The heart, a hollow muscular organ, is located in the center of the chest. The right and left sides of the heart each have an upper chamber (atrium), which collects blood and pumps it into a lower chamber (ventricle), which pumps blood out. To ensure that blood flows in only one direction, each ventricle has an in (inlet) valve and an out (outlet) valve.

- Anatomy of the Heart. Your heart is located under your ribcage in the center of your chest between your right and left lungs. Its muscular walls beat, or contract, pumping blood to all parts of your body. The size of your heart can vary depending on your age, size, and the condition of your heart.

brain parts of the brain The human brain is hugely interconnected but three major components can be identified: the cerebrum, the cerebellum and the brain stem. The brainstem which includes the medulla, the pons and the midbrain, controls breathing, digestion, heart rate and other autonomic processes, as well as connecting the brain with the spinal cord and the rest of the body.

The cardiovascular centre is a part of the human brain responsible for the regulation of the rate at which the The efferent control of the cardiovascular system is exerted through the autonomic nerves. The main parasympathetic influence on the cardiovascular system is a slowing of the heart rate by vagal impulses. The sympathetic adrenergic system, on the other hand, has a much wider variety of actions.

Cardiovascular System of the Head and Neck Cardiovascular System of the Head and Neck. The cardiovascular system of the head and neck includes the vital arteries that provide oxygenated blood to the brain and organs of the head, including the mouth and eyes. It also includes the veins that return deoxygenated blood from these organs to the heart. Among these blood vessels are several unique and important structures that have evolved to help maintain the continuous flow of blood to the brain.

A Tour of the Brain The brain stem contains the midbrain, pons and medulla oblongata. The midbrain — the uppermost part — has fibers that connect the brain stem to the cerebrum and cerebellum; this area is very important in the control of skeletal movements.

Picture of the Heart © 2014 WebMD, LLC. All rights reserved. The heart is a muscular organ about the size of a fist, located just behind and slightly left of the breastbone. The heart pumps blood through the network of arteries and veins called the cardiovascular system. The heart has four chambers: 1  The right atrium receives blood from the veins and pumps it to the right ventricle. 2  The right ventricle receives blood from the right atrium and pumps it to the lungs, where it is loaded with oxygen. 3  The left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle.

The Central Nervous System The brain stem is the region between the diencephalon (thalamus and hypothalamus) and the spinal cord. It consists of three parts: midbrain, pons, and medulla oblongata. The midbrain is the most superior portion of the brain stem. The pons is the bulging middle portion of the brain stem.

Which Brainstem Centers are Involved in CardioÂVascular Regulation? The brain centers involved in cardiovascular regulation are the medullary sympathetic center (vasomotor center), the medullary parasympathetic center (cardio inhibitory center) and the medullary relay station for cardio respiratory afferents. The spinal sympathetic center is located in the intermediolateral horn of the spinal cord (T1 - L2). It has two parts: the pressor area, containing the intermediolateral (IML) cells from which the.
