Understanding the Nervous System Functions

Laura introduces the nervous system, dividing it into the central and peripheral systems. The central nervous system includes the brain and spinal cord, while the peripheral system consists of sensory and motor nerves. The brain is further divided into the cerebrum, cerebellum, and brainstem, each with specific functions. The spinal cord handles reflexes, and sensory nerves transmit information to the brain, which responds via motor nerves.

What are the two main divisions of the nervous system?

• Brain and Spinal Cord

• Sensory and Motor

• Cerebrum and Cerebellum

• Central and Peripheral

Which components make up the central nervous system?

• Sensory and Motor Nerves

• Brain and Spinal Cord

• Cerebrum and Brainstem

• Cerebellum and Brainstem

What is the primary function of the cerebrum?

• Coordinating balance

• Thinking and voluntary movements

• Regulating internal organs

• Reflex actions

Which part of the brain is responsible for balance and coordination?

• Brainstem

• Cerebellum

• Spinal Cord

• Cerebrum

What role does the brainstem play in the body?

• Thinking and memory

• Transmitting sensory information

• Coordinating movements

• Regulating internal organs

What is the spinal cord primarily responsible for?

• Sensory information processing

• Voluntary movements

• Reflex actions

• Balance and coordination

What do sensory nerves do in the peripheral nervous system?

• Regulate internal organs

• Transmit commands to muscles

• Coordinate balance

• Transmit information from sense organs to the central nervous system

How does the brain respond to sensory information?

• By sending commands through sensory nerves

• By regulating internal organs

• By coordinating balance

• By sending commands through motor nerves

Which nerves are responsible for transmitting commands from the brain to muscles?

• Spinal nerves

• Motor nerves

• Cerebral nerves

• Sensory nerves
