The dorsal nucleus of vagus nerve (or posterior nucleus of vagus nerve or dorsal vagal nucleus or nucleus dorsalis nervi vagi or nucleus posterior nervi vagi) [1] is a cranial nerve nucleus of the vagus nerve (CN X) situated in the medulla oblongata of the brainstem ventral to the floor of the fourth ventricle.
Grossman and Taylor (2007) argue that there is no evidence that the dorsal motor nucleus (DMN) is an evolutionarily more primitive center of the brainstem parasympathetic system than the nucleus ambiguus (NA), and review evidence to the contrary. [3]
Micrograph of the posterior portion of the open part of the medulla oblongata, showing the fourth ventricle (top of image) and the hypoglossal nucleus (medial - left of image) and the dorsal motor nucleus of the vagus nerve (lateral - right of image). H&E-LFB stain. Hypoglossal nucleus (XII) - motor; Dorsal motor nucleus of vagus nerve (X ...
With the abducens nucleus it makes up the horizontal gaze centre. [1] It is situated in the pons adjacent to the abducens nucleus. [2] It projects to the ipsilateral abducens (cranial nerve VI) nucleus, and contralateral oculomotor (cranial nerve III) nucleus [note 1] to mediate conjugate horizontal gaze and saccades.
Dorsal cochlear nucleus, a cortex-like structure on the dorso-lateral surface of the brainstem; Dorsal nucleus of vagus nerve, a cranial nerve nucleus for the vagus nerve; Dorsal raphe nucleus; Lateral dorsal nucleus of thalamus; Medial dorsal nucleus of thalamus; Posterior thoracic nucleus (or dorsal nucleus), is a group of interneurons found ...
The posterior thoracic nucleus is a major relay center for unconscious proprioception. Sensory information from muscle spindles and tendon organs is carried by axons of larger neurons in dorsal root ganglia, which synapse onto neurons in the spinal cord including the posterior thoracic nucleus.
The dorsal column–medial lemniscus pathway (DCML) (also known as the posterior column-medial lemniscus pathway (PCML) is the major sensory pathway of the central nervous system that conveys sensations of fine touch, vibration, two-point discrimination, and proprioception (body position) from the skin and joints.
The dorsal trigeminal tract (also dorsal trigeminothalamic tract, or posterior trigeminothalamic tract) are uncrossed second-order sensory fibers conveying fine (discriminative) touch and pressure information from the dorsomedial division of principal sensory nucleus of trigeminal nerve to the ipsilateral ventral posteromedial nucleus of thalamus.
