Neuroanatomi12

Basic terminology in nervous system33 In the CNSSubstantia grisea: collection of nerve cell bodies and their dendrites, gray color during fresh conditionCortex : the outermost layer of gray matter in cerebrum and cerebellumSubstantia alba : collection of nerve fibers, white color during fresh conditionMedulla: a central core of white matter beneath cortex of cerebrum and cerebellumNucleus: a collection ( group ) of cell bodies which have the same shape and function

44Fasciculus ( tract ): a bundle of nerve fibers which have the same origin, termination, pathway and functionFormatio reticularis: an admixture of cross-crossing fibers with larger or smaller groups of nerve cells occupying the meshes

55In the PNSGanglion : a collection of neuronal cell bodies outside the CNSNervus : a bundle of nerve fibers held together by connective tissue sheath

Neuronscellbodydendritesaxon withmyelin sheathsynapsesSchwanncellMoores COA5 2006 Dendrites: carry nerve impulses toward cell body Axon: carries impulses away from cell body Synapses: site of communication between neurons using chemical neurotransmitters Myelin & myelin sheath: lipoprotein covering produced by glial cells (e.g., Schwann cells in PNS) that increases axonal conduction velocity Demyelinating diseases: e.g., Multiple Sclerosis (MS) in CNS or Guillain-Barr Syndrome in PNS77Sensory (Afferent) vs. Motor (Efferent)
