• Fingers, toes, ears

Which type of nerve carries information from the body to the brain?

• Motor nerves

• Sensory nerves

• Auditory nerves

• Visual nerves

What is the function of a motor nerve?

• Control movement

• Produce hormones

• Digest food

• Regulate body temperature

How does damage to the nervous system affect movement?

• Improved movement

• No effect on movement

• Enhanced movement

• Impaired movement

What is the role of the dendrites in a neuron?

• Receives signals from other neurons and transmits them to the cell body.

• Stores energy for the neuron

• Regulates the temperature of the neuron

• Produces neurotransmitters for the neuron

Which type of nerve carries information from the brain to the body?

• Motor nerve

• Sensory nerve

• Mixed nerve

• Autonomic nerve

What are the effects of damage to the sensory nerves?

• Loss of sensation, tingling, numbness, or pain

• Improved coordination and balance

• Enhanced memory and cognitive function

• Increased sensation and strength

What is the function of the myelin sheath?

• Produce hormones for nerve function

• Insulate and protect nerve fibers, increase speed of nerve impulse transmission

• Regulate body temperature

• Store nutrients for nerve cells

What are the symptoms of damage to the nervous system?

• Blurred vision, dizziness, and nausea

• Fever, cough, and sore throat

• Rash, itching, and swelling

• Numbness, weakness, pain, and problems with movement or coordination

How do mixed nerves differ from sensory and motor nerves?

• Mixed nerves contain both sensory and motor fibers

• Mixed nerves are not part of the peripheral nervous system

• Mixed nerves contain only motor fibers

• Mixed nerves contain only sensory fibers
