Flashcards in Neurohisto Deck (12):
1

3 types of neurons

1. bipolar - 1 axon and 1 dendrite
2. pseudounipolar - single process
3. multipolar - single axon, multi-dendrites

2

name of collection of rough ER in axon

nisel substance

3

feature of neuron nucleus

owl's eye nucleus

4

two substances that can be released on post-synaptic cleft and what happens

1. Na - excitation
2. Cl - inhibition

5

2 types of matter and where

1. grey - perikarya (body), fibres, glia, vessels
2. white = fibers, glia, vessels

6

4 different types of glia

1. ogliodendrites - form myelin sheaths
2. astrocytes - support and create blood brain barrier
3. ependyma - line ventricles and central canal
4. microglia - phagocyte cleanup

7

breaks where no myelin is present

nodes of ranvier

8

feature of ependyma

- cover choroid plexuses
- produce and circulate CSF

9

where are cell bodies located in PNS

in ganglia

10

3 different types of fibers in PNS

1. sensory gang. - pseudounipolar
2. autonomic gang. - multipolar - angular profiles
3. nerves - both myelinated and not - sinuous course

11

cells that fibers sit in

schwann cells

12

3 different nerve covering and what they surround

1. endoneurium - surrounds schwann cell and fiber
2. perineurium - surrounds bundle called fascicles
3. epineurium - surrounds whole group of fascicles
