• Neuron

• Muscle cell

What is the primary role of the myelin sheath in a neuron?

• To provide structural support to the cell body.

• To insulate the signal and increase the speed at which the electrical impulses are transmitted.

• To facilitate the reception of stimuli from other neurons.

• To produce and store neurotransmitters.

Which type of neuron is responsible for transmitting information from sensory receptors in peripheral nervous system to the central nervous system?

• Motor neuron

• Efferent neuron

• Interneuron

• Sensory neuron

Which type of ion channel opens in response to changes in membrane potential?

• Chemically-gated channels

• Voltage-gated channels

Which components make up the Central Nervous System (CNS)?

• Sensory and motor divisions.

• The brain and spinal cord.

• Somatic and autonomic nervous systems.

LAST QUESTION:
