Which type of cell is more numerous in the nervous system?

Back

What is the primary function of the motor (efferent) division of the nervous system?

Back

To send signals FROM the CNS to muscles and glands, facilitating movement and responses.

Front

What is the role of the parasympathetic division of the nervous system?

Back

To promote 'rest and digest' functions, conserving energy and maintaining homeostasis.

Front

What are the two main types of cells in the nervous system?

Back

Neurons and Neuroglia: Neurons transmit signals, while neuroglia support and protect neurons.

Front

What is the function of the diencephalon?

Back

It acts as a relay center for sensory information and regulates functions such as sleep, hunger, and thirst.

Front

What is the role of the brain stem?
