In medicine, the pulse is the rhythmic throbbing of each artery in response to the cardiac cycle (heartbeat). [1] The pulse may be palpated in any place that allows an artery to be compressed near the surface of the body, such as at the neck (carotid artery), wrist (radial artery or ulnar artery), at the groin (femoral artery), behind the knee (popliteal artery), near the ankle joint ...
The cerebral arteries describe three main pairs of arteries and their branches, which perfuse the cerebrum of the brain. The three main arteries are the: Anterior cerebral artery (ACA), which supplies blood to the medial portion of the brain, including the superior parts of the frontal and anterior parietal lobes [1]
The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals.It consists of nervous tissue and is typically located in the head (cephalization), usually near organs for special senses such as vision, hearing and olfaction.
The cardiovascular centre, or cardiovascular center, is part of the medulla oblongata of the brainstem. [1] [2] Normally, the heart beats without nervous control.In some situations, such as exercise, and major trauma, the cardiovascular centre is responsible for altering heart rate.
The human brain is the central organ of the nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system ...
Near the superior frontal gyrus these arteries anastomose with branches from the pericallosal artery of the anterior cerebral artery. Pre-Rolandic artery (precentral): The artery extends out on the medial surface of the operculum and supplies the posterior parts of the middle and inferior frontal gyri as well as the lower parts of the pre ...
The arbor vitae / ˌ ɑːr b ɔːr ˈ v aɪ t iː / (Latin for "tree of life") is the cerebellar white matter, so called for its branched, tree-like appearance.In some ways it more resembles a fern and is present in both cerebellar hemispheres. [1]
The area postrema is a paired protuberance found at the inferoposterior limit of the fourth ventricle. [ 1 ] [ 5 ] Specialized ependymal cells are found within the area postrema. These cells differ slightly from the majority of ependymal cells (ependymocytes), forming a unicellular epithelial lining of the ventricles and central canal .
