Nervous System

What are the three main parts of a neuron?

• Fingers, toes, nose

• Dendrites, cell body, and axon

• Roots, stem, leaves

• Heart, lungs, liver

Which part of the neuron receives signals from other neurons?

• Synapse

• Cell body

• Dendrites

• Axon

What is the function of the central nervous system?

• To regulate body temperature

• To digest food

• To produce hormones

• To process and coordinate information received from the sensory organs and send out instructions to the body's muscles and glands.

Explain the process of a reflex arc.

• In a reflex arc, the sensory signal is transmitted directly to the effector organ without involving the spinal cord or brain.

• The process of a reflex arc involves the transmission of a sensory signal to the spinal cord, where it is processed and a motor response is sent back to the effector organ.

• A reflex arc is a voluntary response to a stimulus that involves the brain sending a signal to the spinal cord, which then activates the effector organ.

• The process of a reflex arc involves the transmission of a sensory signal to the brain, where it is processed and a motor response is sent back to the effector organ.

What is the role of the sensory neuron in a reflex arc?

• Carries the signal to the central nervous system

• Regulates the body temperature

• Sends the signal to the muscles for a response

• Processes the information in the brain

What is the function of the autonomic nervous system?

• Regulates involuntary bodily functions

• Aids in digestion and nutrient absorption

• Regulates conscious thoughts and decision making

• Controls voluntary muscle movements

Name the three main parts of a reflex arc.

• brain, spinal cord, muscle

• receptor, sensory neuron, motor neuron

• skin, bone, blood

• heart, lungs, liver

Explain the role of the motor neuron in a reflex arc.

• Motor neurons transmit signals from the central nervous system to the muscles or glands.

• Motor neurons transmit signals from the brain to the sensory organs.

• Motor neurons have no role in a reflex arc.

• Motor neurons transmit signals from the muscles to the central nervous system.

What is the role of the interneuron in a reflex arc?

• Interneurons transmit signals from the sensory neurons to the motor neurons.

• Interneurons transmit signals from the brain to the sensory organs.

• Interneurons have no role in a reflex arc.

• Interneurons transmit signals from the muscles to the sensory neurons.

What is the role of the axon in a neuron?

• Axon transmits signals from the neuron to other neurons or to effector cells.

• Axon receives signals from other neurons.

• Axon has no role in a neuron.

• Axon processes the information in the neuron.
