1

Which pathways are reactive?

Spinothalamic

2

Which pathways are discriminative?

Dorsal column-medial leminicsus
Spinocerebellum

3

Which motor pathways are voluntary?

Pyramidal- cerebral cortex
-corticospinal
-corticobulbar

4

Which motor pathways are involuntary/ autonomous?

Extrapyrmidal- brainstem
-reticulospinal
-tetcospinal
-ruborospinal
-vesticbulospinal

5

What is spinothalamic

Spinal cord- thalamus- cortex
Anterior- Pressure and tough
Lateral- Pain and temp

6

What is dorsal column-medial leminiscus pathway?

Lemon with good posture (proprioceptive)
T6 above- cunate nucleus
T6 below- gracile nucleus

Light touch/ vibration

7

What is spinocerebellum

Spine to cerebellum
Unconscious
Prorioceptive

8

What is corticospinal?

Below head
Ends at spinal cord
Desiccates
-lateral pyramids of medulla
-anterior spinal cord

9

What is corticobulbar?

Head and neck
Ends at brainstem

10

What is reticulospinal?

Reticular formation to spinal cord
Facilitates and inhibits voluntary movement

11

What is tectospinal?

Tectum (Superior colliculi) to spinal cord
Vision- head moves towards the light

12

What is ruborospinal?

Red nucleus to spinal cord
Caught red handed
fine control of hand

13

What is vestibulospinal?

Vestibular nuclei to spinal cord
Balance

14

What do the inferior and superior colliculi do?

Superior= Vision
Inferior- Auditory

15

Brocco's area

actually speaking-frontal (motor)

16

Werneickes area

Understanding speech

17

Pre central gyrus

Motor

18

Post central gyrus

Somatosensory
Touch something, feel it later

19

What is the limbic system?

Inlcudes thalamus, hypothalamus, basal nuclei, cerebral cortex and olefactory cortex

Controls visceral functions through the autonomic NS and endocrine
Involved in- Emotions, memory, reproduction and nutrition

20

What are the 3 cerebral white matter fibres?

Association
commissure
projection

21

What are association fibres?

Same hemisphere, connect areas
Example= fornix

22

What are projection fibres?

Connect one cerebrum to other part of the brain/spinal cord
Example= Internal capsule

23

What are commissure fibres?

Connect one hemisphere to the other
Example- corpus collosum

24

What is the occipital part of the brain for?

Vision

25

What is the frontal part of the brain for?

Personality and memory, emotion and motor

26

What is parietal for?

Language and touch- contains wernickes area

27

What is the cerebellum for?

Movement and coordination

28

What is the temporal for?

Hearing, learning and feelings

29

What is the brainstem for?

Heart rate, breathing and temperature
