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 .
The pontine tegmentum contains nuclei of several cranial nerves and consequently has a role in several groups of sensory and motor processes. The principal sensory nucleus of the trigeminal nerve represents touch and position information of the head and face, but not the neck or back of the head, which are innervated by the cervical nerves.
Trochlear nerve nucleus: This is the fourth cranial nerve. Red nucleus : This is a motor nucleus that sends a descending tract to the lower motor neurons . Substantia nigra pars compacta : This is a concentration of neurons in the ventral portion of the midbrain that uses dopamine as its neurotransmitter and is involved in both motor function ...
Cranial nerves are the nerves that emerge directly from the brain (including the brainstem), of which there are conventionally considered twelve pairs.Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head and neck, including the special senses of vision, taste, smell, and hearing.
The solitary nucleus (SN) (nucleus of the solitary tract, nucleus solitarius, or nucleus tractus solitarii) is a series of neurons whose cell bodies form a roughly vertical column of grey matter in the medulla oblongata of the brainstem. Their axons form the bulk of the enclosed solitary tract. The solitary nucleus can be divided into different ...
The sensory trigeminal nerve nuclei are the largest of the cranial nerve nuclei, and extend through the whole of the midbrain, pons and medulla, and into the upper cervical spinal cord. The nucleus is divided into three parts, from rostral to caudal (top to bottom in humans): The mesencephalic nucleus; The principal sensory nucleus
The superior salivatory nucleus (or nucleus salivatorius superior) is a visceral motor cranial nerve nucleus of the facial nerve (CN VII). It is located in the pontine tegmentum . [ citation needed ] It projects pre-ganglionic visceral motor parasympathetic efferents (via CN VII ) to the pterygopalatine ganglion , and submandibular ganglion .
The abducens nucleus is the originating nucleus from which the abducens nerve (VI) emerges—a cranial nerve nucleus. This nucleus is located beneath the fourth ventricle in the caudal portion of the pons near the midline, [ 1 ] medial to the sulcus limitans .
