UTA ANATOMY FINAL 2026 ACTUAL
QUESTIONS WITH VERIFIED
ANSWERS.
Basic structure of a neuron - correct answer-cell body,
dendrites, axon, synaptic end bulb
Chemical gradients - correct answer-k out, na in
Electrical gradients - correct answer-seperates charges of
pos/neg
membrane is more permeable to k than na
Anterograde vs retrograde - correct answer-anterograde: cell
body to synaptic knob
retrograde: synaptic knob to cell body
neuroglia in CNS/ PNS - correct answer-PNS: satellite/
schwann
, Page | 2
CNS: astrocytes, oligodendrocytes, microglia, ependymal
Membrane potential - correct answer-charge differences across
membrane
Sodium potassium pump - correct answer-3 na out, 2 k in
action potential - correct answer-depolarize: more positive
repolarize: more negative
hyperpolarize: more negative than at rest
Fastest signal - correct answer-mylinated
larger diameter
higher temperature
saltatory
IPSP vs EPSP - correct answer-EPSP: na, ca
IPSP: Cl
, Page | 3
Where is the epidural space? - correct answer-Between spinal
dura mater and wall of vertebral canal
What is dorsal root ganglion? - correct answer-Cell bodies of
sensory neurons
What is a spinal nerve? - correct answer-mixed nerves, afferent
(sensory) and efferent (motor)
Posterior, anterior, and lateral gray horns.. what material is in
each? - correct answer-posterior: sensory nerons, cell bodies,
and axons of interneurons
anterior: somatic motor nuclei
lateral: in thoracic and lumbar segments; autonomic motor
nuclei
3 layers of CT around the spinal nerve in order and how many
in each section - correct answer-epineurium, perineurium, and
endoneurium
, Page | 4
What part of the body is controlled by each ramus? - correct
answer-posterior: deep muscles and skin posterior surface of
trunk
anterior: muslces and structures of upper and lower limbs, skin
anterior and lateral trunk
3 parts of the brainstem - correct answer-midbrain, pons,
medulla oblongata
3 layers of crainial meninges in order - correct answer-dura
mater, arachnoid mater, pia mater
what is the blood brain barrier? what cell is involved? - correct
answer-isolates CNS neural tissue from general circulation
endothelial cells and astrocytes
what is the choroid plexus? what cell is involved? - correct
answer-produces CSF
ependymal
