neuroanatomy 3 Flashcards
1
Q
The Papez
A
- Hippocampus and the enterohinal cortex. Hippocampus is important for forming new memories
- Fimbria: gather to form the fornix
- Fibres go to the mamillary body-> thalamus -> cingulate gyrus ->enterohinal cortex
2
Q
Function of the internal capsule
A
- Carries fibres from the cerebrum to the spinal cord
3
Q
The striatum
A
- remember stripy
- the caudate nucleus and the putamen together
4
Q
3 main types of nuclei in the thalamus
A
- sensory nuclei
- cerebellar and basal ganglia
- connected to associative and limbic system
5
Q
Basal ganglia
A
- part of the diencephalon
- there are direct and indirect pathways
- direct pathways initiate movement
- indirect pathways
6
Q
Hypothalamus
A
- sits beneath the thalamus
- sits in top of the pituitary gland
- has multiple inputs
7
Q
Amygdala
A
- gives fear/anxiety/aggression
8
Q
Spinal cord in
A
- horns: have lower motor neurons
9
Q
How is the spinal cord arranged
A
- organised into specific bundles of fibres
10
Q
Spinothalamic tract
A
- decussates at the bottom: at spinal cord
- for crude touch.pain
11
Q
Dorsal column mediated pathway
A
- sensory fibres ascend and decussate at the medulla (at top). For joint position
12
Q
Corticospinal tract
A
- for movement
