Ch. 10 - Nervous System I

What is the primary function of the nervous system?

• To regulate blood sugar levels

• To digest food

• To act as the master regulatory system

• To produce hormones

Which of the following is NOT a function of the nervous system?

• Sensory input

• Integration and processing

• Motor output

• Producing red blood cells

What type of cells in the nervous system respond quickly to changes and conduct electrical impulses?

• Neuroglia

• Neurons

• Red blood cells

• Muscle cells

What is the role of neuroglia in the nervous system?

• Conduct electrical impulses

• Protect, support, insulate, and nourish neurons

• Detect changes in the environment

• Stimulate muscles to respond

Which of the following is part of the Central Nervous System (CNS)?

• Cranial nerves

• Spinal nerves

• Brain

• Efferent nerves

What is the primary function of the Peripheral Nervous System (PNS)?

• To process information

• To connect the CNS to other body parts

• To produce hormones

• To regulate blood flow

Which of the following is a subdivision of the Peripheral Nervous System?

• Central nerves

• Spinal cord

• Afferent (sensory)

• Brain

What is the primary function of sensory receptors in the sensory division?

• Transmit impulses from CNS to effectors

• Perform sensory function by detecting changes

• Transmit voluntary commands to skeletal muscles

• Transmit involuntary commands to viscera

How are impulses conducted in the sensory division?

• Along peripheral nerves to CNS for integration

• From CNS to effectors

• To skeletal muscles

• To viscera

What is the role of neurons in the motor division?

• Convert information into impulses

• Transmit impulses from CNS to effectors

• Detect changes

• Conduct impulses to CNS
