neuroanatomy Flashcards
1
Q
afferent
A
sensory
2
Q
efferent
A
motor
3
Q
sympathetic system
A
mobilize energy
4
Q
parasympathetic
A
conserve energy
5
Q
anterior side of the brain
A
front of the brain
6
Q
posterior side of the brain
A
back of the brain
7
Q
coronal (frontal) section
A
- Slicing the brain so you can see both hemispheres
- The dorsal side of the brain to ventral side of the brain
- Cut from top (superior - dorsal) to bottom (inferior - ventral) of the brain
8
Q
horizontal section
A
- Cutting horizontally through the brain
- Like from right ear to left ear
9
Q
mid-sagittal (medial) section
A
- Cutting brain exactly in the half (in the middle)
- Cutting from the front of your brain to the back
- From anterior (front) to posterior (back)
10
Q
ANTERIOR side of the brain
A
the front of your brain
11
Q
POSTERIOR side of the brain
A
the back of your brain
12
Q
dorsal –> superior
A
the top of your brain
13
Q
ventral –> inferior
A
the bottom of your brain
14
Q
divisions of the forebrain
A
telencephalon & diencephalon
15
Q
divisions of the midbrain
A
mesencephalon
16
Q
divisions of the hindbrain
A
metencephalon & myelencephalon
17
Q
myelencephalon contains…
A
- medulla
- reticular formation (reticular activating system)
18
Q
mesencephalon contains…
A
- pons
- cerebellum
- also houses reticular formation
19
Q
mesencephalon
A
- tectum (roof)
- tegmentum (floor)
20
Q
diencephalon
A
- thalamus
- hypothalamus
21
Q
telencephalon
A
- cerebal cortex
- amygdala
- basal ganglia
22
Q
the longitudinal fissure
A
- divides our cerebrum in half (our brain in half)
- separates right hemisphere from left hemisphere
- convolutions (sulcus) folding inwards
23
Q
corpus callosum
A
- largest commissure that connects our left and right hemispheres
- axons are sending messages between the hemispheres
- damage specifically here means the entire neuron is not killed only the axon is damaged which causes dysfunction
24
Q
contralateral organization
A
- your left hemisphere controls you right half of your body
- your right hemisphere controls your left half of your body
