Quiz: Sensory Neurons, Interneurons, and Motor Neurons

What is the structure of a sensory neuron?

• Cell body, dendrites, and axon

• Stem, leaves, and roots

• Nucleus, mitochondria, and Golgi apparatus

• Protein, carbohydrates, and lipids

Describe the function of the dendrites in a sensory neuron.

• Produce hormones for the endocrine system

• Store energy for future use

• Regulate blood flow in the circulatory system

• Receive signals from other neurons or sensory receptors

Explain the role of the axon in a sensory neuron.

• Stores information in the sensory receptor

• Transmits nerve impulses from the sensory receptor to the central nervous system

• Regulates body temperature

• Receives nerve impulses from the central nervous system

How does a sensory neuron transmit signals to the central nervous system?

• By sending physical signals

• Through electrical impulses

• By releasing hormones

• Through chemical reactions

What is the function of interneurons in the nervous system?

• Regulate heart rate

• Connect sensory and motor neurons

• Control voluntary movements

• Produce hormones

Where are interneurons located in the body?

• Peripheral nervous system

• Central nervous system

• Digestive system

• Respiratory system

How do interneurons facilitate communication between sensory and motor neurons?

• By directly controlling the movement of sensory neurons

• By producing hormones that stimulate motor neurons

• By converting sensory signals into visual information

• By receiving signals from sensory neurons and transmitting them to motor neurons

Explain the concept of reflex arcs and the involvement of interneurons.

• Interneurons process sensory information and coordinate the appropriate response.

• Interneurons are responsible for transmitting information from the brain to the spinal cord.

• Interneurons process visual information and control muscle movement.

• Reflex arcs involve only motor neurons and no sensory input.

What are the different motor neuron pathways in the body?

• Olfactory tract, optic tract, auditory tract, and gustatory tract

• Corticospinal tract, rubrospinal tract, vestibulospinal tract, and reticulospinal tract

• Spinal tract, cranial tract, peripheral tract, and central tract

• Sensory tract, autonomic tract, somatic tract, and sympathetic tract

Describe the pathway of a motor neuron signal from the brain to a muscle for a voluntary movement.

• The motor neuron signal travels from the brain to the skin and then to the muscle.

• The motor neuron signal travels from the brain to the heart and then to the muscle.

• The motor neuron signal travels from the brain to the lungs and then to the muscle.

• The motor neuron signal travels from the brain through the spinal cord and then to the muscle.
