The cranial cavity houses the Brain, Meninges, and the Cerebrospinal Fluid. The primary function of the brain is supplying information to the rest of the body and to help it function as whole. It helps supply some of the cranial nerves from the face to the feet and also to help get the body performing critical bodily functions.
The skull is a bone protective cavity for the brain. [1] The skull is composed of three types of bone: cranial bones, facial bones, and ear ossicles. Two parts are more prominent: the cranium (pl.: craniums or crania) and the mandible. [2] In humans, these two parts are the neurocranium (braincase) and the viscerocranium (facial skeleton) that ...
Brain size. The size of the brain is a frequent topic of study within the fields of anatomy, biological anthropology, animal science and evolution. Measuring brain size and cranial capacity is relevant both to humans and other animals, and can be done by weight or volume via MRI scans, by skull volume, or by neuroimaging intelligence testing.
242787. Anatomical terms of neuroanatomy. [ edit on Wikidata] In neuroanatomy, the ventricular system is a set of four interconnected cavities known as cerebral ventricles in the brain. [ 1 ][ 2 ] Within each ventricle is a region of choroid plexus which produces the circulating cerebrospinal fluid (CSF).
In human anatomy, the neurocranium, also known as the braincase, brainpan, or brain-pan, [ 1 ][ 2 ] is the upper and back part of the skull, which forms a protective case around the brain. [ 3 ] In the human skull, the neurocranium includes the calvaria or skullcap. The remainder of the skull is the facial skeleton.
The cerebrospinal fluid circulates in the subarachnoid space around the brain and spinal cord, and in the ventricles of the brain. Cerebrospinal fluid (CSF) is a clear, colorless body fluid found within the tissue that surrounds the brain and spinal cord of all vertebrates. CSF is produced by specialised ependymal cells in the choroid plexus of ...
The Posterior cranial fossa is colored in blue, yellow, and red. The posterior cranial fossa is the part of the cranial cavity located between the foramen magnum, and tentorium cerebelli. It is formed by the sphenoid bones, temporal bones, and occipital bone. It lodges the cerebellum, and parts of the brainstem.
Pia mater (/ ˈpaɪ.ə ˈmeɪtər / or / ˈpiːə ˈmɑːtər /), [1] often referred to as simply the pia, is the delicate innermost layer of the meninges, the membranes surrounding the brain and spinal cord. Pia mater is medieval Latin meaning "tender mother". [1] The other two meningeal membranes are the dura mater and the arachnoid mater.
