Neurons Quiz

Which of the following best describes a multipolar neuron?

• One process attached to the cell body

• More than two processes attached to the cell body

• Only found in the olfactory epithelium

• Primarily associated with sensory functions

Bipolar neurons are typically found in which locations?

• Retina, olfactory epithelium, and inner ear

• Spinal cord, brainstem, and cerebellum

• Peripheral nerves only

• Muscles and glands

Which of the following is true about unipolar neurons?

• They have two processes attached to the cell body.

• They are multipolar and associated with motor functions.

• They are all sensory neurons with one process attached to the cell body.

• They are typically involved in interneuronal communication.

Which of the following describes sensory neurons?

• They carry motor outputs to effectors.

• They are multipolar and primarily associated with integration.

• They are either unipolar or bipolar and carry sensory inputs.

• They only function within the central nervous system.

Which structural class of neurons is associated with motor neurons?

• Unipolar

• Bipolar

• Multipolar

• Pseudounipolar

Interneurons typically occur between which types of neurons?

• Sensory and interneurons

• Sensory and motor neurons

Which of the following is NOT true of interneurons?

• They can be bipolar or multipolar.

• They are primarily involved in integrating information.

• They occur between sensory and motor neurons.

• They carry motor outputs directly to muscles.

Which of the following best describes a nerve impulse?

• A wave of ion movement only at the axon terminals

• An electrical wave involving depolarization and repolarization traveling down an axon

• The movement of ions only at the cell body

• A chemical signal that does not involve changes in membrane potential

Nerve impulses are typically propagated from the axon hillock to:

• The dendrites

• The axon terminals

• The nucleus

• The cell body

Which of the following is NOT necessary to understand nerve impulse propagation?

• Ion channels

• Membrane potential

• Types of neurotransmitters

• Different types of membrane potentials
