Dorsal Ans: Top/up/back
© 2026 Assignment Expert
Ventral Ans: Bottom/down/belly side
Guru01 - Stuvia
Lateral Ans: away from the midline
Medial Ans: toward the midline
4 elements of the CNS Ans: Cerebrum, cerebellum, brain stem, spinal
cord
Dorsal root spinal nerve Ans: Carries afferent (sensory) info into the spinal
cord
Ventral root spinal nerve Ans: Carries efferent (motor) information from
the spinal cord
Dorsal root ganglia Ans: clusters of sensory neuron cell bodies outside
the spinal cord
Are the dorsal root ganglia in the somatic or visceral peripheral nervous
system? Ans: Somatic
, For Expert help and assignment handling,
2
Somatic PNS Ans: The part of the peripheral nervous system that
innervates the skin, joints, and skeletal muscles.
Visceral (autonomic) PNS Ans: Neurons which innervate the internal
organs, blood vessels, and glands; sympathetic division prepares body
for action; parasympathetic division prepares body for rest.
Cranial nerves Ans: 12 nerves from brain stem, mostly innervate the
head, some from CNS and PNS

3 meninges (from dorsal to ventral) that surround the brain Ans: Dura
mater (hard), Arachnoid membrane, pia mater (soft)
Guru01 - Stuvia
ventricles of the brain Ans: canals and caverns in the brain that contain
cerebrospinal fluid (CSF)
Choroid plexus Ans: specialized tissue in ventricles that secretes CSF
Where is CSF reabsorbed? Ans: Subarachnoid space or lymphatic
system
CLARITY Visualization Technique Ans: replace lipids in brain with
transparent liquid, allows view of non-lipid structures
CT (computed tomography) Ans: scan a series of X-ray photographs
taken from different angles and combined by computer into a
composite representation of a slice of the brain's structure. Quick,
cheap, easy. Does not provide detail
MRI (magnetic resonance imaging) Ans: Measures how hydrogen
atoms respond to perturbations of strong magnetic field. Signals are
