Question 1

When does the Neural Tube begin to develop?

Answer 1

When the foetus is around 3-4 weeks old

Question 2

The neural tube then divides into three sections, what are they called?

Answer 2

Forebrain
Midbrain
Hindbrain

Question 3

When does the neural tube divide into the three sections?

Answer 3

By the time the foetus is 5 weeks old.

Question 4

At around 5 weeks, the forebrain divides into two cavities, what are they called?

Answer 4

Anterior (front)
Posterior (back)

Question 5

Brain

Answer 5

The organ in your head made up of nerves that processes information and controls behaviour.

Question 6

Forebrain

Answer 6

The anterior part of the brain, including the hemispheres and the central brain structures.

Question 7

Midbrain

Answer 7

The middle section of the brain forming part of the central nervous system

Question 8

Hindbrain

Answer 8

The lower part of the brain that includes the cerebellum, pons and medulla oblongata.

Question 9

Anterior

Answer 9

Directed towards the front, when used in relation to our biology.

Question 10

Posterior

Answer 10

Directed towards the back, when used in relation to our biology.

Question 11

Cerebellum

Answer 11

An area of the brain near to the brainstem that controls motor movements (muscle activity)

Question 12

Medulla Oblongata

Answer 12

Connects the upper brain to the spinal cord and controls automatic responses

Question 13

Involuntary Response

Answer 13

A response to a stimulus that occurs without someone making a conscious choice. They are automatic, such as reflexes

Question 14
