What are the two main parts of the nervous system?

Central Nervous System (CNS) and Peripheral Nervous System (PNS)

Name the three main regions of the brain.

The three main regions of the brain are the hindbrain, midbrain, and forebrain.

The two parts of the Central Nervous System are the brain and the spinal cord.

Somatic Nervous System (SNS) and Autonomic Nervous System (ANS)

I can identify the main parts of the nervous system.

1
The nervous system has two main parts: the central nervous system which includes the brain and spinal cord, and the peripheral nervous system which includes the nerves.
2
The brain has three main regions: the hindbrain, the midbrain, and the forebrain.
3
The peripheral nervous system (PNS) can be divided into the somatic nervous system which controls skeletal muscles, and the autonomic nervous system which controls internal organs.
