anatomy

34 Terms

1

soma

cell’s body

New cards
2

nucleus

a prominent feature of the cell body; contains the nucleolus

New cards
3

mitochondria

energy source for the neuron

New cards
4

rough endoplasmic reticulum and golgi apparatus

responsible for synthesizing and packaging proteins

New cards
5

plasma membrane

lipid bilayer as in other cells

critical role in ion flow into and out of the neuron

New cards
6

axon

send info

New cards
7

axon hillock

the initial segment of the axon that tapers from the cell body

New cards
8

myelin sheath

glial cell wrapping around the axon

acts as an insulator

important for signal propagation

increase speed of transmission

New cards
9

node of ranvier

area that exists between the myelin sheaths

increase speed of transmission

New cards
10

terminal bouton (axon terminal)

the end of the axon

presynaptic component of a synapse

contains many mitochondria and synaptic vesicles

New cards
11

dendrites

receive info

New cards
12

diameter

proximal dendrites taper from the soma, and are thicker than axons

distal dendrites become thinner as they branch

New cards
13

dendritic spines

thorn-like projections that extend from the dendritic shaft

increase surface area of dendrites for more action potentials to occur

New cards
14

frontal lobe

higher cog func (judgement/thinking), primary/secondary motor cortexes, Broca’s area (speech production/ only on left side)

New cards
15

parietal lobe

primary/ secondary somatosensory cortexes (pressure, pain, temp), Wernicke’s area (language comprehension/ only on left side)

New cards
16

occipital lobe

vision (most posterior lobe)

New cards
17

temporal lobe

auditory areas, memory, odor detection, part of the wernicke’s area (language comprehension / only on left side)

New cards
18

insula

taste

New cards
19

superior colliculus

visual processing (posterior side of midbrain/ 2 of 2 little bumps)

New cards
20

inferior colliculus

auditory processing (posterior side of midbrain/ 2 of 2 little bumps)

New cards
21

peduncles

a group of dispersed axon fibers that collect into a compact bundle of white matter

New cards
22

cerebellar peduncles

contain axons that connect the cerebellum with other structures (axons from and to the spinal cord travel through the inferior cerebellar peduncle)

New cards
23

precentral gyrus

anterior the central sulcus

New cards
24

postcentral gyrus

posterior the central sulcus

New cards
25

central sulcus

on both hemispheres, running from left to right

New cards
26

parieto-occipital sulcus

between parietal and occipital lobe

New cards
27

lateral fissure

separates the temporal lobe form the frontal and parietal lobe

New cards
28
<p>longitudinal fissure</p>

longitudinal fissure

deep groove that separates the two cerebral hemispheres
