Flashcards in Introduction Deck (30):
1

The CNS is comprised of?

Brain and spinal cord

2

Name the three regions of the brain.

Hindbrain. Midbrain. Forebrain.

3

The hindbrain is also known as...

The rhombencephalon.

4

The hindbrain can be subdivided into...

The medulla oblongata. The pons. The cerebellum.

5

In embryonic development, what gives rise to the medulla oblongata?

The mylencephalon.

6

In embryonic development, what gives rise to the pons?

The metencephalon.

7

In embryonic development, what gives rise to the cerebellum?

The metencephalon.

8

The midbrain is also known as...

The mesencephalon.

9

The midbrain can be subdivided into...

The tectum. The cerebral peduncle.

10

Describe the location of the tectum.

The dectum is dorsal to the cerebral aqueduct.

11

Describe the location of the cerebral peduncle.

The cerebral peduncle is ventral to the cerebral aqueduct.

12

The tectum is comprised of what two structures?

The superior and inferior colliculi.

13

What is the function of the superior colliculi?

Responsible for visual processing and eye movements.

14

What is the function of the inferior colliculi?

Responsible for auditory processing.

15

The cerebral peduncle is comprised of what two structures?

The tegmentum. The crura cerebri.

16

Describe the location of the tegmentum and crura as part of the cerebral peduncle.

The tegmentum occupies the dorsal part of the cerebral peduncle. The crus cerebri occupy the ventral part on each side of the midline.

17

Name the structure that separates the tegmentum and the crura.

Substantia nigra.

18

The forebrain is also known as...

The prosencephalon.

19

The forebrain can be subdivided into...

The diencephalon. The telencephalon.

20

Name the two structures that the diencephalon is comprised of.

The thalamus. The hypothalamus.

21

In embryonic development, the diencephalon is derived from...

The anterior part of the neural tube.

22

Name the two structures that the telencephalon is comprised of.

Cerebral cortex. Basal ganglia.

23

What is the cerebral cortex?

An outer layer of laminated grey matter.

24

What is grey matter?

Aggregations of neuronal cell bodies and their local processes.

25

What is the basal ganglia?

A collection of nuclei.

26

What is white matter?

Collections of nerve fibres (axons, mostly myelinated, and dendrites) with few or no neuronal cell bodies.

27

What is a neurophil?

Interconnected neuronal processes occupying the space between neuronal cell bodies within the grey matter.
