What are the four major regions of the brain and their functions?

Answer 1

The four major regions of the brain are

* the brainstem

* the diencephalon

* the cerebellum

* the cerebrum

The areas within these regions that might be affected by alcohol exposure in the womb:

In the brainstem: Reticular Activating System (RAS) - filters important and unimportant information from sensory input

In the diencephalon:

* thalamus - filters sensory information, senses pain

* hypothalamus - regulates hunger, thirst, body temperature

* epithalamus - secretes melatonin, sets day/night cycle

* Limbic system: contains parts of cerebrum and diencephalon, controls emotion and behavior

In the cerebellum: balance, gait, posture

In the cerebrum:

* corpus callosum - transfers information between right and left brains

* frontal lobes - regulates impulses, inhibitions, judgment

* basal nuclei (ganglia) - regulates movement and facial expressions

Answer 2

1. Cerebrum: responsible for higher brain functions such as thinking, memory, and voluntary movements.
2. Cerebellum: coordinates muscle movements and balance.
3. Brainstem: controls basic life functions like breathing, heart rate, and digestion.
4. Diencephalon: includes the thalamus and hypothalamus, which help regulate hormones, body temperature, and emotions.
