Function. The diencephalon is the region of the embryonic vertebrate neural tube that gives rise to anterior forebrain structures including the thalamus, hypothalamus, posterior portion of the pituitary gland, and the pineal gland. The diencephalon encloses a cavity called the third ventricle. The thalamus serves as a relay centre for sensory ...
Diencephalic syndrome, or Russell's syndrome, is a rare neurological disorder seen in infants and children and characterised by failure to thrive and severe emaciation despite normal or slightly decreased caloric intake. Classically there is also locomotor hyperactivity and euphoria. Less commonly diencephalic syndrome may involve skin pallor ...
The cerebrum is the largest part of the brain. Depending upon the position of the animal, it lies either in front or on top of the brainstem. In humans, the cerebrum is the largest and best-developed of the five major divisions of the brain. The cerebrum is made up of the two cerebral hemispheres and their cerebral cortices (the outer layers of ...
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).
The midbrain or mesencephalon is the rostral -most portion of the brainstem [ 2 ] connecting the diencephalon and cerebrum with the pons. [ 3 ] It consists of the cerebral peduncles, tegmentum, and tectum. It is functionally associated with vision, hearing, motor control, sleep and wakefulness, arousal (alertness), and temperature regulation.
The brainstem (or brain stem) is the posterior stalk-like part of the brain that connects the cerebrum with the spinal cord. [ 1 ] In the human brain the brainstem is composed of the midbrain, the pons, and the medulla oblongata. [ 1 ] The midbrain is continuous with the thalamus of the diencephalon through the tentorial notch, and sometimes ...
Anatomy. The thalamus is a paired structure of gray matter about four centimetres long, located in the forebrain which is superior to the midbrain, near the center of the brain with nerve fibers projecting out to the cerebral cortex in all directions. Each of the thalami may be subdivided into at least 30 nuclei, giving a total of at least 60 ...
