  • Reverberating

    •cyclical stimulation of the circuit

    •E.g., breathing rhythm

  • Perikaryon

    •cytoplasm within cell body

  • Chromatophilic Substance

    •free ribosomes and rough endoplasmic reticulum

  • Anaxonic

    neuron without axon

  • Axon collateral

    side branch of main axon

  • Terminal arborizations

    fine extensions at the end of the axon and its collaterals

  • Synaptic knobs

    expanded area at tip or arborization 

  • Neurofilament

    intermediate filament that form neurofibrils

  • perivascular feet

    astrocyte form this around capillary

  • neurofibril node

    without mylination, gap

  • neurilemma

    the thin, outer membrane of neurolemmocyte

  • axosomatic

    •between synaptic knobs and soma

  • axodendritic

    •between synaptic knobs and dendrites

  • axoaxonic

    •between synaptic knobs and axon

  • Axon collateral

    •side branches off the main axon

  • saltatory conduction

    An impulse “jumps” from one neurofibril node to another

  • continuous conduction

    Unmyelinated axons impulse travels along the entire length of the axon membrane

  • Neural plate

    •thickened ectoderm that undergoes neurulation

  • Neural groove

    •develops in plate; cells at margin become neural crest

  • neural tube

    Folds on either side of groove grow together forming hollow

    •forms the central nervous system

  • dural venous sinuses

    form in locations where the two layers of the dura mater have separated:

    Superior sagittal sinus:

    2.Inferior sagittal sinus:

    3.Transverse sinuses:

    4.Occipital sinus:

  • Caudate nucleus

    helps coordinate walking

  • infundibulum

    inferiorly from hypothalamus to attach to pituitary gland

  • Tentorium cerebelli

    •horizontal fold that separates cerebrum from cerebellum

  • interventricular foramen

    third ventricle communicates with lateral ventricles

  • Wernicke area

    recognizes and comprehends spoken and written language

    •Typically located in left hemisphere overlapping the parietal and temporal lobes

  • Arcuate fibers

    Association tracts within a lobe

  • Longitudinal fasciculi

    Association tracts •different lobes of same hemisphere

  • Lentiform nucleus

    •nucleus—involved in movement and muscle tone

    •Composed of putamen and globus pallidus

  • Claustrum

    consciousness and processing of multiple sensory stimuli

  • denticulate ligaments

    •that suspend and anchor the spinal cord laterally to the dura mater

  • funiculus

    White matter names

  • rami communicante

    extend between the spinal nerves and the sympathetic trunk ganglia

  • Musculocutaneous

    Formed from the lateral cord, anterior division of the brachial plexus (bicep brachii)

  • Cauda equina

    •“Horse’s tail”—axons that extend inferiorly from spinal cord’s conus medullaris

  • Filum terminale

    •Thin strand of pia mater within cauda equina that attaches conus medullaris to coccyx

  • Basal plate

    form anterior horns, lateral horns and anterior part of gray commissure

  • conus medullaris

    tapering inferior end of spinal cord

  • Alar plates

     form posterior horns and posterior part of gray commissure
