• The brain provides conscious awareness and consists of many regions, which are responsible for different functions.

• The brain controls only involuntary actions such as heartbeat and breathing.

• The brain is responsible solely for muscle movement and coordination.

• The brain acts only as a relay station for sensory information without processing it.

Which part of the nervous system transfers messages to and from the brain and is responsible for simple reflex actions that do not involve the brain?

• The Cerebellum

The Somatic Nervous System facilitates communication between the CNS and the outside world.

• True

• False

What is the main function of the Autonomic Nervous System?

• It is important for homeostasis and maintains internal processes like body temperature and heart rate.

• It controls voluntary muscle movements such as walking and writing.

• It is responsible for processing sensory information from the environment.

• It regulates the production of red blood cells in the bone marrow.

• False
