Views > 49,000 (when accessed 10/12/2020)
Covers:
motor neuron
myelin sheath on axons = white
cell bodies and dendrites = gray
gray matter internal location in Cervical, Thoracic, Lumbar, Sacral regions of spinal cord is in columns in a butterfly shape
ventral/anterior horn - somatic motor neuron cell bodies / lower motor neurons
lateral/intermediate horn - visceral motor neuron cell bodies
(T1-L2 and S2-S4 spinal cord levels only)
dorsal/posterior horn - sensory neuronal input, cell bodies in dorsal root ganglion
ventral horn large in cervical region (to innervate upper limb)
ventral horn small in thoracic region (to innervate intercostal muscles)
ventral horn also large in lumbar and sacral regions (to innervate lower limb)
Spinal cord White matter
by The Noted Anatomist
Duration: 9:14
Posted: Apr 15, 2015
Views > 22,000 (when accessed 10/12/2020)
Covers:
white matter at periphery of spinal cord = tracts of axons
ascending axons/tracts go to brain
descending axons/tracts go from brain
sensory axons enter at every level - white matter increases as we ascend the spinal cord
motor axons travel to every level - white matter
decreases as we descend the spinal cord
dorsal column / posterior column - ascending ipsilateral sensory tracts for fine touch, proprioception and vibration
anterolateral system / spinothalamic tract - ascending contralateral sensory tracts for pain, temperature and touch
corticospinal tract - descending, ipsilateral motor tracts on route to the ventral gray matter
visual clues that distinguishing the cervical, thoracic, lumbar and sacral spinal cord segments in cross section

Covers: roots, spinal nerve trunk, rami (branches)
dorsal root information/axons going in - sensory - afferent (one way street)
ventral root information/axons going out - motor - efferent (one way street)
spinal nerve trunk (two way street)
ventral rami often form plexuses
cervical plexus (neck muscles), brachial plexus (upper limb), (intercostal nerves), lumbar plexus (part of lower limb), sacral plexus (lower limb)
dorsal rami - deep back muscles, skin of back
