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.
The disease begins in structures of the lower brainstem and the olfactory system. In particular, the dorsal motor nucleus of the vagus nerve in the medulla oblongata and anterior olfactory nucleus are affected. [6] Lewy neurites, thread-like alpha-synuclein aggregates, are more prevalent than globular Lewy bodies in this stage. [4]
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 ...
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. [29]
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 ...
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.
