Absence of the great cerebral vein is a congenital disorder.The deep cerebral veins of the brain normally drain through the great cerebral vein. In its absence, the veins from the diencephalon and the basal ganglia drain laterally into the transverse sinus instead of conjoining in the midline through the Galenic drainage system. [7]
The brain is the central organ of the human nervous system, and with the spinal cord makes up the central nervous system. The brain consists of the cerebrum, the brainstem and the cerebellum. It controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sense organs, and making ...
A magma chamber is a large pool of liquid rock beneath the surface of the Earth. The molten rock, or magma, in such a chamber is less dense than the surrounding country rock, which produces buoyant forces on the magma that tend to drive it upwards. [1] If the magma finds a path to the surface, then the result will be a volcanic eruption ...
Next up, the team behind the project aims to create a full map of the brain of a mouse, which would require between 500 and 1,000 times the amount of data of the human brain sample.
Cerebral veins. Sagittal section of the skull, showing the sinuses of the dura. (Cerebral veins labeled at center left.) In human anatomy, the cerebral veins are blood vessels in the cerebral circulation which drain blood from the cerebrum of the human brain. They are divisible into external (superficial cerebral veins) and internal (internal ...
Anatomical terms of neuroanatomy. [edit on Wikidata] The longitudinal fissure (or cerebral fissure, great longitudinal fissure, median longitudinal fissure, interhemispheric fissure) is the deep groove that separates the two cerebral hemispheres of the vertebrate brain. Lying within it is a continuation of the dura mater (one of the meninges ...
The adult human brain weighs on average about 1.5 kg (3.3 lb). [1] In men the average weight is about 1370 g and in women about 1200 g. [2][contradictory] The volume is around 1260 cm 3 in men and 1130 cm 3 in women, although there is substantial individual variation. [3] Yet another study argued that adult human brain weight is 1300-1400 g for ...
Thalamus. The thalamus (pl.: thalami; from Greek θάλαμος, "chamber") [1] is a large mass of gray matter on the lateral walls of the third ventricle forming the dorsal part of the diencephalon (a division of the forebrain). Nerve fibers project out of the thalamus to the cerebral cortex in all directions, known as the thalamocortical ...
