Q

What is The cerebral cortex?

A

outer layer of the cerebrum that is composed of grey matter, approx 2-4 mm

22
Q

What are the 5 lobes of the cerebrum?

A

Frontal, parietal, temporal, occipital and insula

23
Q

What are the 3 types of white matter tracts?

A
  1. Association tracts
  2. Commissural tracts
  3. Projection tracts
24
Q

What is the role of an Association tract?

A

Conduct impulses between gyri of the same hemisphere

25
Q

what is the role of a commissural tract, give examples

A

Conduct nerve impulses from gyri in one hemisphere to another, examples are; Corpus callosum, anterior commissure and posterior commissure

26
Q

What are projection tracts?

A

Brain –> SC or

SC –> Brain

27
Q

What are the components of the basal nuclei?

A
  • Globus pallidus (Lat and Med)

29
Q

Damage to what area would cause fluent aphasia

A

Wernicke’s area

30
Q

Where is the frontal eye feild found and what does it do?

A

it is found in the premotor area, nearest to the eyes of the humunculous, and controls the eye movement, such as scanning

31
Q

does the dorsal root contain motor or sensory neurons?

A

Sensory

32
Q

Belly button line

36
Q

What is the pathway of the Medial Lemniscal tract?

A

hand –> Cuneate Nucleus

CF –> Decussates –> Thalamus

Thalamus –> Post central gyrus

37
Q

What is the pathway of the spinothalamic tract

A

Arm–> Decussation –> Lateral spinothalamic tract

LST –> thalamus

Thalamus –> Post- central gyrus

38
Q
