Anatomy & Physiology Nervous System Review

What is the insulating membrane that surrounds parts of the axon that helps to protect & propagate action potential?

• Myelin Sheath

• Axon Terminal

• Dendrite

• Synapse

What is the difference between sensory neurons and motor neurons?

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

• Sensory neurons are responsible for muscle movement, while motor neurons detect environmental stimuli.

• Sensory neurons transmit signals to the heart, while motor neurons transmit signals to the lungs.

• Sensory neurons are found only in the brain, while motor neurons are found throughout the body.

What is an action potential?

• A rapid rise and fall in voltage or membrane potential across a cellular membrane.

• A slow change in temperature within a cell.

• A type of cellular respiration process.

• A method of cell division.

What is the largest structure of the brain that is 2/3 of brain mass?

• Cerebrum

• Cerebellum

• Brainstem

• Thalamus

What part of the brain is responsible for coordination and balance?

• Cerebellum

• Cerebrum

• Brainstem

• Thalamus

What is the functional unit of the nervous system?

• Neuron

• Glial cell

• Synapse

• Axon

What is the function of the spinal cord?

• To transmit signals between the brain and the rest of the body.

• To produce hormones that regulate metabolism.

• To filter toxins from the blood.

• To store memories and experiences.

What is the role of the autonomic nervous system?

• To control voluntary muscle movements.

• To regulate conscious thought processes.

• To control involuntary bodily functions such as heart rate and digestion.

• To manage sensory information processing.

What are neurotransmitters?

• Chemical messengers that transmit signals across a synapse from one neuron to another.

• Hormones that regulate mood and behavior.

• Proteins that provide structural support to neurons.

• Enzymes that break down neurotransmitters in the synapse.

What is the difference between the central nervous system and the peripheral nervous system?

• The central nervous system consists of the brain and spinal cord, while the peripheral nervous system includes all the nerves outside the central nervous system.

• The central nervous system is responsible for voluntary movements, while the peripheral nervous system controls involuntary actions.

• The central nervous system is located in the limbs, while the peripheral nervous system is located in the brain and spinal cord.

• The central nervous system includes sensory organs, while the peripheral nervous system includes only the brain.
