Nervous System Quiz

What are the main parts of the nervous system?

• brain, spinal cord, and nerves

• heart, lungs, and liver

• stomach, intestines, and kidneys

• muscles, bones, and skin

Explain the structure and function of the brain in the nervous system.

• The brain is only responsible for controlling breathing

• The brain is the control center of the nervous system, responsible for processing information, controlling body functions, and coordinating movements.

• The brain has no role in processing information or coordinating movements

• The brain is made up of muscle tissue

Describe the role of the spinal cord in the nervous system.

• It is responsible for producing hormones that regulate the nervous system.

• It serves as a pathway for nerve signals and plays a role in reflex actions.

• It functions as a storage unit for excess nerve signals.

• It has no role in the nervous system and is purely for structural support.

How does the nervous system coordinate and control body activities?

• By using chemical reactions in the body

• By controlling the movement of muscles and bones

• Through the release of hormones into the bloodstream

• By transmitting electrical signals between the brain, spinal cord, and nerves.

What are the primary functions of the nervous system?

• Transporting oxygen, removing waste products, and fighting infections

• Digesting food, regulating body temperature, and controlling muscle movement

• Producing hormones, filtering blood, and storing nutrients

• Receiving sensory input, integrating information, and coordinating motor output

What is the function of a neuron?

• Regulating body temperature

• Digesting food

• Transmitting information in the form of electrical signals

• Producing hormones

Describe the process of how a neuron transmits signals.

• Electrical impulse travels down the neuron and triggers release of neurotransmitters

• Chemical signals travel down the neuron and trigger the release of neurotransmitters

• The neuron releases electrical signals that travel to the brain

• Neurotransmitters trigger the release of electrical impulses in the neuron

Explain the difference between sensory neurons and motor neurons.

• Sensory neurons transmit signals from the central nervous system to muscles and glands, while motor neurons transmit signals from sensory receptors to the central nervous system.

• Sensory neurons transmit signals from muscles to the central nervous system, while motor neurons transmit signals from the central nervous system to sensory receptors.

• Sensory neurons transmit signals from sensory receptors to the central nervous system, while motor neurons transmit signals from the central nervous system to muscles and glands.

• Sensory neurons transmit signals from the brain to the spinal cord, while motor neurons transmit signals from the spinal cord to the brain.
