Overview

How the brain grows from the neural tube into the forebrain, midbrain and hindbrain, what the medulla and cerebellum do from birth, and how nature and the environment shape development.

Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    From which structure in the embryo does the brain develop?

    Model answer

    The brain develops from the neural tube. The neural tube forms within the first month after conception.

  2. 2

    Name the three main regions that the front end of the neural tube swells into.

    Model answer

    The neural tube swells into the forebrain, the midbrain and the hindbrain.

  3. 3

    Which adult brain structures develop from the forebrain?

    Model answer

    The forebrain becomes the cerebrum, which includes the cerebral cortex. The thalamus and hypothalamus also develop from the forebrain.

  4. 4

    What kinds of function does the forebrain eventually control?

    Model answer

    The forebrain controls higher functions such as thinking, planning and language. The forebrain also plays a major part in emotion.

  5. 5

    What is the role of the midbrain?

    Model answer

    The midbrain relays visual and auditory information to the forebrain. The midbrain also helps control eye movements and reflexes to sudden sights and sounds.

  6. 6

    Which structures develop from the hindbrain?

    Model answer

    The hindbrain develops into the cerebellum, the pons and the medulla. The pons and medulla form much of the brainstem.
