Play an AI-generated podcast conversation about this lesson

Which part of the nervous system acts as the primary control center for processing and transmitting information throughout the body?

Peripheral nervous system

Central nervous system (correct)

Somatic nervous system

Autonomic nervous system

What is the function of effectors in the nervous system?

Detect stimuli

Respond to stimuli (correct)

Transmit impulses

Act as control centers

What is the difference between grey matter and white matter in the brain and spinal cord?

Both refer to the same type of cells in the nervous system (correct)

White matter is found in the central nervous system, grey matter in the peripheral nervous system

Grey matter consists of myelinated axons, white matter comprises cell bodies

White matter consists of cell bodies, grey matter comprises myelinated axons
