Human Nerves

Home -> BiologicalLifeResearch -> HumanNerves

This page is intended to list all nerves of biological human, which connect mind to human limbs and visceral organs. Related findings are structured by other research themes.

Coverage verified by:

FUNCTIONAL CLASSIFICATION OF INNERVATION

General Innervation - like spinal cord:

  • GSE (General Somatic Efferent) - motor to somatic voluntary skeletal muscles (derived from somites)
  • GSA (General Somatic Afferent) - sensory to skin, joints, muscle and tendon receptor endings, nasal and oral cavity
  • GVE (General Visceral Efferent) = Autonomic Efferents - motor to smooth muscles in general and smooth muscles of skin (arrector pilae muscles) and blood vessels, secretomotor to glands
  • GVA (General Visceral Afferent) - sensory to gut and its derivatives, pharynx, blood vessels, glands and internal organs

Special Innervation - only found in head:

  • SSA (Special Somatic Afferent) - special senses of vision, auditory sensation and vestibular apparatus
  • SVA (Special Visceral Afferents) - chemical senses of taste and by analogy smell
  • SVE (Special Visceral Efferents) - motor to voluntary skeletal muscles derived from branchial arches (these muscles develop in association with pharynx, which is rostral end of gut and therefore visceral)

CRANIAL NERVES

MULTI-CATEGORY NERVES

  • nerve of pterygoid canal (MA:[OF THE PTERYGOID CANAL]; vidian nerve) ORIGIN={union of deep petrosal nerve and greater petrosal nerve}; DISTRIBUTION={pterygopalatine ganglion and branches}; MODALITY={parasympathetic and sympathetic}; FIBERS={sympathetic:see deep petrosal nerve (carotid nerve); parasympathetic: see greater petrosal nerve (facial nerve)}
  • pterygopalatine nerves (MA:[BRANCHES OF PTERYGOPALATINE GANGLION]; sphenopalatine nerves) DISTRIBUTION={the two nerves which connect the maxillary nerve to the pterygopalatine GANGLION}; MODALITY={they are the sensory roots of the ganglion}; FIBERS={GSA:all maxillary sensory from pterygopalatine to trigeminal; GVE:great and deep petrosal to lacrimal gland}

  • vagus nerve
    • vagus nerve, anterior trunk (MA:[VAGUS NERVE],[BRANCH OF ANTERIOR VAGUS],[BRANCH OF ANTERIOR VAGUS]; left); ORIGIN={consists primarily of fibers from the left vagus, but also contains a few fibers from the right vagus nerve}; DISTRIBUTION={contributes to the esophageal plexus}
    • vagus nerve, posterior trunk (MA:[VAGUS NERVE]; right); ORIGIN={branch of the vagus nerve, consists primarily of fibers from the right vagus, but also contains a few fibers from the left vagus}; DISTRIBUTION={contributes to the esophageal plexus}
  • cardiac innervation (MA:[PLEXUS], MA:[BODY PLEXUS])
  • proper digital nerves of hand (MA:[DIGITAL NERVES OF HAND])
