Nucleus (neuroanatomy) In neuroanatomy, a nucleus (pl.: nuclei) is a cluster of neurons in the central nervous system, [1] located deep within the cerebral hemispheres and brainstem. [2] The neurons in one nucleus usually have roughly similar connections and functions. [3] Nuclei are connected to other nuclei by tracts, the bundles (fascicles ...
Nuclear bodies (also known as nuclear domains or nuclear dots) are biomolecular condensates, membraneless structures found in the cell nuclei of eukaryotic cells. [1] Nuclear bodies include Cajal bodies , the nucleolus , nuclear speckles (also called splicing speckles), histone locus bodies, and promyelocytic leukemia protein (PML) nuclear ...
Central nucleus (autonomic nervous system) Medial nucleus (accessory olfactory system) Cortical and basomedial nuclei (main olfactory system) Lateral and basolateral nuclei (frontotemporal cortical system) Extended amygdala. Stria terminalis. Bed nucleus of the stria terminalis. Claustrum. Basal ganglia.
Pulvinar nuclei. Hind- and mid-brains; postero-lateral view. (Pulvinar visible near top.) The pulvinar nuclei or nuclei of the pulvinar (nuclei pulvinares) are the nuclei (cell bodies of neurons) located in the thalamus (a part of the vertebrate brain). [ 1 ] As a group they make up the collection called the pulvinar of the thalamus (pulvinar ...
62209. Anatomical terms of neuroanatomy. [edit on Wikidata] In neuroanatomy, the lateral geniculate nucleus (LGN; also called the lateral geniculate body or lateral geniculate complex) is a structure in the thalamus and a key component of the mammalian visual pathway. It is a small, ovoid, ventral projection of the thalamus where the thalamus ...
Trochlear nerve (cranial nerve 4) – eye rotation. Trigeminal nerve (cranial nerve 5) – sensation from the face and certain motor functions such as biting and chewing. Abducens nerve (cranial nerve 6) – certain eye rotation. Facial nerve (cranial nerve 7) – facial expression and taste sensations from the tongue.
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.
Motor nuclei in red; sensory in blue. (The olfactory and optic centers are not represented.) A cranial nerve nucleus is a collection of neurons (gray matter) in the brain stem that is associated with one or more of the cranial nerves. Axons carrying information to and from the cranial nerves form a synapse first at these nuclei.
