HPNU 3050 - SPINAL CORD (exam 3)
2 motor neurons of ANS - ANS-preganglionic and postganglionic
All funiculi incorporate _____ and _____ tracts. - ANS-motor and sensory tracts
anterior ramus of spinal nerve - ANS-innervates the anterior and lateral skin and muscles of the
trunk and gives upward thrust to nerves of the top and lower limbs
ascending tracts of white count number function - ANS-behavior sensory impulses
autonomic motor characteristic - ANS-motor output that isn't always consciously or is
involuntarily managed; effectors are cardiac muscle, easy muscle, and glands
Dens of axis (C2) characteristic - ANS-pivot for rotation
descending tracts of white count feature - ANS-behavior motor instructions
describe anterior sacral foramina - ANS-openings on the anterior facet of the sacrum for nerves
and vessels
describe parasympathetic lower motor neurons - ANS-lengthy preganglionic axons, short
postganglionic axons
(ganglia are near or within the effector)
describe sympathetic decrease motor neurons - ANS-short preganglionic axons, lengthy
postganglionic axons (ganglia are near spinal wire)
describe the gray and white remember in a pass segment of the spinal wire - ANS-important
place of grey count shaped like a butterfly and surrounded with the aid of white remember in 3
columns
grey depend is neuron mobile our bodies with little myelin
white count is myelinated axons
describe what travels via the spinal cord and nerves - ANS-sensory facts and motor outputs will
journey to and from the spinal cord thru spinal nerves
divisions of ANS - ANS-parasympathetic and sympathetic
Drawing of Cross-Section of Spinal Cord - ANS-DRAW IT RN
, Examples of effectors - ANS-smooth muscle, cardiac muscle, glands
filum terminale - ANS-*pia mater*
anchors spinal wire to coccyx
Function of atlas (C1) - ANS-sure movement of head (nodding)
Function of axis (C2) - ANS-no movement of the head (shaking)
function of white commissure - ANS-connects the white count number of the right and left facets
of the spinal twine
capabilities of ANS - ANS-preserve homeostasis
gray rami communicantes place and function - ANS-postganglionic sympathetic axons from
sympathetic trunk to spinal nerve
"exit ramps"
how are white matter funiculi prepared - ANS-organized into tracts
How many cervical nerves are there? - ANS-8 pairs
How many cervical vertebrae are there? - ANS-7
How many coccygeal vertebrae are there? - ANS-four fused
How many lumbar vertebrae are there? - ANS-five
How many pairs of spinal nerves are there? - ANS-31 pairs
How many sacral vertebrae are there? - ANS-5 fused
How many thoracic vertebrae are there? - ANS-12
How many vertebrae are there (inclusive of sacrum and coccyx)? - ANS-33 (7 cervical, 12
thoracic, five lumbar, five sacral, 4 coccygeal)
lumbosacral enlargement of spinal cord - ANS-thicker location within the spinal twine in which
the decrease limbs are innervated. Spinal nerves springing up from this location form the
lumbosacral plexus.
Motor worried gadget function - ANS-initiates and transmits records from the CNS to effectors
