The cranial cavity, also known as intracranial space, is the space within the skull that accommodates the brain.The skull is also known as the cranium. [1] The cranial cavity is formed by eight cranial bones known as the neurocranium that in humans includes the skull cap and forms the protective case around the brain.
The cerebrum (pl.: cerebra), telencephalon or endbrain [1] is the largest part of the brain, containing the cerebral cortex (of the two cerebral hemispheres) as well as several subcortical structures, including the hippocampus, basal ganglia, and olfactory bulb. In the human brain, the cerebrum is the uppermost region of the central nervous system.
The brain is the central organ of the human 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 ...
The intercostal space (ICS) is the anatomic space between two ribs (Lat. costa). Since there are 12 ribs on each side, there are 11 intercostal spaces, each numbered for the rib superior to it. Since there are 12 ribs on each side, there are 11 intercostal spaces, each numbered for the rib superior to it.
The supratentorial region contains the cerebrum, while the infratentorial region contains the cerebellum. Although the Roman era anatomist Galen commented upon it, the functional significance of this neuroanatomical division was first described using ‘modern’ terminology by John Hughlings Jackson, founding editor of the medical journal Brain.
In anatomy, the infratentorial region of the brain is the area located below the tentorium cerebelli. The area of the brain above the tentorium cerebelli is the supratentorial region. The infratentorial region contains the cerebellum, while the supratentorial region contains the cerebrum. The infratentorial dura is innervated by nerves from C1-C3.
The cisterna magna (posterior cerebellomedullary cistern, [1] or cerebellomedullary cistern [2] [3]) is the largest of the subarachnoid cisterns.It occupies the space created by the angle between the caudal/inferior surface of the cerebellum, and the dorsal/posterior surface of the medulla oblongata (it is created by the arachnoidea that bridges this angle [3]).
Cisterna magna also called cerebellomedullary cistern - the largest of the subarachnoid cisterns. It lies between the cerebellum and the medulla oblongata. It receives CSF from the fourth ventricle via the median aperture (foramen of Magendie). The cisterna magna contains: The vertebral artery and the origin of the posterior inferior cerebellar ...
