The pathways mentioned above belong to the somatic motor and somatic sensory systems.
Somatic sensory fibers innervate predominantly the skin, muscle and tissues other than the viscera.
Visceral (autonomic) motor nuclei are located in between the somatic sensory and motor areas of the spinal cord grey matter.
This occurs gradually (elongated nuclei in medulla, rounder in pons and midbrain), b) The sensory nucleus of CN5 does not break up but is continuous from spinal cord through midbrain, c) The motor nucleus of CN5 is confined to the pons, d) There are three sensory nuclei in the brain stem - the vestibulocochlear complex (CN8), sensory nucleus of CN5, and nucleus solitarius. e) Solitarius is a visceral sensory nucleus (CNs 7, 9, 10). 0 The sensory nucleus of CN5 is somatic sensory (CNs 5, 7, 9, 10 and possibly others - but the predominant input is from CN5). g) aMbiguus is Motor (CNs 9, 10) h) Nucleus solitarius is solitarily confined to the medulla as are nucleus ambiguus, the nucleus of CN12, the dorsal motor nucleus of CN10 and the salivatory nuclei, i) Nuc. 8 overlaps the medulla and pons.
The rostral medulla (Fig. 22D) has 3 bumps posterolaterally and 3 bumps anterolaterally-very convenient, for dotted lines between the bumps divide the medulla into the somatic motor, autonomic, and somatic sensory zones.
