Divisions of nervous system Flashcards
1
Q
What makes up the brain
A
- The cerebrum
- The midbrain
- The pons
- The medulla oblongata
- The cerebellum
2
Q
what protects the brain
A
- The Cranium
- The meninges
3
Q
The cerebrum
A
- Largest part of the brain composed of 2 cerebral hemispheres
- The hemispheres are separated by a cerebral fissure.
4
Q
What connects the 2 cerebral hemispheres of the cerebrum
A
- A mass of white matter called corpus callosum
5
Q
Each cerebral hemisphere is divided into four cerebral hemispheres, list them.
A
- the frontal lobe
- The parietal lobe
- The temporal lobe
- The occipital lobe
6
Q
outer part of the brain
A
- Grey matter called the cerebral cortex
7
Q
What name is given to the folds of the cerebral cortex
A
Gyri
8
Q
what separates the gyri
A
Sulcus (sulci) or fissure
9
Q
sulci examples
A
- The central sulcus (fissure of Rolando)
- The lateral Sulcus (fissure of syvius)
10
Q
The lateral sulcus
A
- Lies on the inferior and lateral aspects of the cerebral hemispheres
- Separates the temporal lobe from the frontal and the parietal lobes.
11
Q
The central sulcus
A
- Runs from the upper medial surface of the cerebral cortex.
- separates the frontal from
parietal lobes.
12
Q
Examples of gyri
A
- Precentral gyri
- Postcentral gyri
13
Q
Precentral gyri
A
Lies in front of the central sulcus
14
Q
Postcentral gyri
A
Lies behind the central sulcus
15
Q
Higher centres of the cerebral cortex
A
- The motor area
- The sensory area
- The auditory area
- The visual area
- The motor speech area
- The parietal area
