ANP 1106: NEUROANATOMY UPDATED ACTUAL
QUESTIONS AND CORRECT ANSWERS
Question:
1. What 6 cells make up the nervous tissue?
Answer:
Astrocytes,
Microglia
Ependymal cells
Oligodendrycytes
Satellite cells
Schwan cells
Question:
2. What is an astrocyte?
Answer:
Apart of the CNS, most abundant and anchors the neurons close to capillaries
Question:
3. What are microglial cells?
Answer:
Protective function, monitor well being of neurone and can turn into
macrophages
Question:
4. What are oligodendrocytes?
Answer:
A type of glial cell that forms insulating myelin sheaths around the axons of
neurons in the central nervous system.
Question:
5. What are satellite cells?
Answer:
Surround neuron cell bodies in ganglia and can alter the chemical environment of
these neurons
Question:
6. What are schawnn cells?
Answer:
Form myelin sheath in PNS and needed for PNS neuron regeneration
, Question:
7. What are multipolar neurons, their abundance and where
can they be found?
Answer:
Have 3 or more processes, 1 is an axon and the rest are dendrites. They are the
most abundant in the body and can be found in the CNS.
Question:
8. What are bipolar neurons, what is their abundance and
where can they be found?
Answer:
Bipolar neurons have 2 processes, very rare and can be found in the retina or
olfactory mucosa.
Question:
9. What is a unipolar neuron, what is it's abundance and
where can it be found?
Answer:
A unipolar neuron has a single short process originating from the cell body.
- peripheral process is associated with sensory reception
- central process enters the CNS
Process is an axon
Question:
10. What classifies sensory neurons?
Answer:
Transmits signal towards the CNS
Most (primary) are unipolar, but soem can be bipolar
Those in the CNS are multipolar
Question:
11. What classifies as motor neurons?
Answer:
Transmits signals towards efferent organs and from the CNS.
Most are multipolar - most are in the CNS
Question:
12. What are association neurons?
Answer:
Most abundant functional neurons, make up CNS, multipolar and share info.
