II. Anatomy

  1. Components
    1. Paired Cranial Nerves (12)
    2. Paired spinal nerves (31): Vertebrae imperfectly match the spinal nerve roots
      1. Cervical Nerve Roots (8)
        1. Cervical cord has 7 Vertebrae but has 8 nerve root pairs
        2. C1 exits above the C1 Vertebrae
        3. C8 exits below the C7 Vertebrae
      2. Thoracic Nerve Roots (12)
      3. Lumbosacral Nerve Roots (10)
        1. Spinal cord transitions to individual nerves below the L2 Vertebrae
        2. Analogous to the hairs of a horse (cauda equina)
      4. Coccyx (1)
  2. Spinal Levels
    1. Posterior Sensory Nerve root (dorsal root and spinal Ganglion)
    2. Anterior Motor Nerve root (ventral root)
  3. Dermatomes
    1. Sensory components are distributed along the skin in long swaths of nerve innervation

Ontology: Peripheral Nerves (C0031119)

Definition (FMA) Neural tree (organ) which is directly continuous with the neuraxis. Examples: phrenic nerve, radial nerve, ilioinguinal nerve, sciatic nerve.
Definition (UWDA) Subdivision of peripheral nervous system which is a tree whose trunk is a branch of a somatic nerve plexus (cervical, brachial or lumbosacral); it has shared parts with the somatic nerves that contribute to its parent plexus. Examples: phrenic nerve, radial nerve, ilioinguinal nerve, sciatic nerve.
Definition (NCI) Any nerve outside the brain or spinal cord that connects with peripheral receptors or effectors.
Definition (NCI_CDISC) Any nerve outside the brain or spinal cord that connects with peripheral receptors or effectors. (NCI)
Definition (MSH) The nerves outside of the brain and spinal cord, including the autonomic, cranial, and spinal nerves. Peripheral nerves contain non-neuronal cells and connective tissue as well as axons. The connective tissue layers include, from the outside to the inside, the epineurium, the perineurium, and the endoneurium.

Ontology: Peripheral Nervous System (C0206417)

Definition (MSHCZE) Nervový systém mimo oblast mozku a míchy. Periferní nervový systém má dvě velké části - autonomní a somatickou. Autonomní nervový systém zahrnuje enterickou, parasympatickou a sympatickou část. Somatický nervový systém zahrnuje oblast kraniálních a míšních nervů s jejich ganglii a periferní smyslové receptory. R
Definition (NCI) That part of the nervous system consisting of the nerves and neurons that reside or extend outside the central nervous system.
Definition (MSH) The nervous system outside of the brain and spinal cord. The peripheral nervous system has autonomic and somatic divisions. The autonomic nervous system includes the enteric, parasympathetic, and sympathetic subdivisions. The somatic nervous system includes the cranial and spinal nerves and their ganglia and the peripheral sensory receptors.
Definition (PSY) Anatomical systems of structures outside the brain and spinal cord composed of neural tissue.
Definition (CSP) peripheral nervous system is outside of the brain and spinal cord; it has autonomic and somatic divisions; the autonomic nervous system includes the enteric, parasympathetic, and sympathetic subdivisions and the somatic nervous system includes the cranial and spinal nerves and their ganglia and the peripheral sensory receptors.
