Flashcards in Block 2 Nervous System Deck (38):
1

sympathetic chain ganglion is blank

motor

2

nerve cells are blank under light microscopy

quite large

3

nerve cells have very prominent blank which offshoot from cell body

processes

4

RER of a nerve cell is in the cell body and is aka blank

nissl body

5

processes are aka

dendrites

6

cell body is aka

soma

7

junction between axon and soma

axon hillock

8

nerve cells are acidophilic or basophilic

basophilic

9

neuropile is important because it is the space between cells where blank occurs

synapses

10

most synapses are blank

axodendritic

11

presynaptic area of em has these

synaptic vesicles

12

postsynaptic area of cells in em are electron blank

dense

13

size of synaptic cleft

20-30 nm

14

axons are usually basophilic or acidophilic

acidophilic

15

lighter colored axons are blank or blank

lightly myelinated, nonmyelinated

16

white matter is on the blank in the spinal cord

outside

17

epineurium is made of blank

dense regular ct

18

perineurium is made of blank

epithelium like

19

inner capsule cells

schwann (satellite) cells

20

outer capsule is made of blank

fibroblasts

21

sympathetic nervous system is in the form of a blank or sympathetic ganglion that form a blank

paravertebral, chain

22

white ramus has blank

preganglionic fibers

23

gray ramus has blank fibers

postganglionic

24

ganglion along aorta that are found going along their corresponding blood vessels

prevertebral collateral ganglion

25

prevertebral collateral ganglion innervate blank

organs

26

parasympathetic ganglion synapse blank target organ

close to

27

sympathetic ganglion synapse blank target organ

far from

28

autonomic nerve cells dont blank very well

stain

29

autonomic nerve cells are blank shaped

wavy

30

group of cell bodies

ganglion

31

three plexuses in esophagus from superficial to deep

esophageal, myenteric, submucosal

32

esophageal plexus is made of blank fibers

autonomic

33

epineurium binds blank together

fascicles

34

perineurium has blank so fluids cant move through and resembles a blank tissue

tight junctions, squamous epithelial

35

gaps in myelin sheath for saltatory conduction

node of ranvier

36

motor ganglion have blank schwann cells unlike sensory ganglion

scattered

37

axons are grouped into blank in nerve cells

fascicles

38

dorsal root ganglion are blank

sensory
