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 and motor ...
Posterior segment of the diencephalon. [ 1] The epithalamus includes the habenular nuclei, the stria medullaris, the anterior and posterior paraventricular nuclei, the posterior commissure, and the pineal gland. [ 2] The epithalamus ( pl.: epithalami) is a posterior (dorsal) segment of the diencephalon. [ 3]
Subthalamus. Coronal slices of human brain showing the basal ganglia, subthalamic nucleus (STN) and substantia nigra (SN). STN is in subthalamus; SN is not. The subthalamus or prethalamus is a part of the diencephalon. [ 1] Its most prominent structure is the subthalamic nucleus. The subthalamus connects to the globus pallidus, a basal nucleus ...
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.
In the anatomy of the brain of vertebrates, the forebrain or prosencephalon is the rostral (forward-most) portion of the brain. The forebrain controls body temperature, reproductive functions, eating, sleeping, and the display of emotions. Vesicles of the forebrain (prosencephalon), the midbrain (mesencephalon), and hindbrain (rhombencephalon ...
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 ...
The brainstem (or brain stem) is the stalk-like part of the brain that connects the forebrain (the cerebrum and diencephalon) with the spinal cord. [ 1] In the human brain, the brainstem is composed of the midbrain, the pons, and the medulla oblongata. [ 1][ 2] The midbrain is continuous with the thalamus of the diencephalon through the ...
Mammillary body. Sagittal section, "Corpus mamillare" highlighted. [ 1] Coronal section of brain through intermediate mass of third ventricle. (Label "Corpora mamillaria" at bottom.) The mammillary bodies are a pair of small round bodies, located on the undersurface of the brain that, as part of the diencephalon, form part of the limbic system.
