Unit 4 Review: The Nervous System 24-25

What role does integration play in the nervous system?

• Gathering sensory information

• Sending signals to the brain

• Processing and interpreting sensory input

• Activating motor neurons

Motor output in the nervous system involves:

• Gathering information from sensory receptors

• Processing sensory input

• Sending signals from the brain to the body

• Interpreting environmental data

What is the primary function of the Central Nervous System (CNS)?

• To link the CNS to the rest of the body

• To carry impulses to and from the brain

• To interpret sensory information and give instructions

• To control cardiac and smooth muscle

Which part of the nervous system links the CNS to the rest of the body?

• Central Nervous System

• Peripheral Nervous System

• Autonomic Nervous System

• Somatic Nervous System

What is the primary function of the afferent (sensory) division in the nervous system?

• To send impulses away from the CNS

• To deliver impulses to the CNS

• To control muscle movements

• To regulate hormone levels

What is the primary function of efferent neurons?

• Transmit sensory information to the CNS

• Send impulses from the CNS to organs

• Process information within the CNS

• Detect changes in the environment

What is activated by the motor (efferent) division?

• Sensory receptors

• Muscles and glands

• Brain cells

• Digestive enzymes

Which of the following is a characteristic of the Somatic Nervous System?

• Involuntary control

• Smooth muscle control

• Skeletal muscle control

• Controlled by Vagus Nerve

What is the exception to voluntary control in the Somatic Nervous System?

• Cardiac muscle

• Reflexes

• Glands

• Visceral sensory
