General Nerve Quiz

What are the main parts of a neuron and their functions?

• Dendrites, cell body, axon, and axon terminals

• Roots, stem, leaves, and flowers

• Heart, lungs, liver, and kidneys

• Wheels, engine, seats, and steering wheel

Describe the process of action potential in a neuron.

• The process of action potential in a neuron involves depolarization of the neuron's membrane, opening of voltage-gated ion channels, and influx of sodium ions.

• The process of action potential in a neuron involves the release of neurotransmitters into the synapse

• Action potential in a neuron is caused by the movement of potassium ions out of the neuron

• The process of action potential in a neuron is not related to the opening of ion channels

What is the role of neurotransmitters in the nervous system?

• They store memories in the brain

• They produce energy for the nervous system

• They regulate blood flow in the brain

• They transmit signals across synapses

Explain the difference between excitatory and inhibitory neurotransmitters.

• Excitatory and inhibitory neurotransmitters have the same function

• Inhibitory neurotransmitters have no effect on the likelihood of an action potential

• Excitatory neurotransmitters decrease the likelihood of an action potential

• Excitatory neurotransmitters increase the likelihood of an action potential in the receiving neuron, while inhibitory neurotransmitters decrease the likelihood of an action potential.

What are the different types of nerve cells and their functions?

• Visual neurons, auditory neurons, and olfactory neurons

• Sensory neurons, motor neurons, and interneurons

• Afferent neurons, efferent neurons, and central neurons

• Red neurons, blue neurons, and green neurons

Compare and contrast sensory neurons and motor neurons.

• Sensory neurons carry information from the brain to the muscles and glands, while motor neurons carry information from the sensory receptors to the spinal cord.

• Sensory neurons carry information from the central nervous system to the muscles and glands, while motor neurons carry information from the sensory receptors to the brain.

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

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

How does the peripheral nervous system differ from the central nervous system?

• Function of nerves

• Location of nerves

• Color of nerves

• Size of nerves

Explain the functions of the spinal cord in the peripheral nervous system.

• It is responsible for producing hormones

• It functions as a storage organ for nutrients

• It helps in regulating body temperature

• It functions as a pathway for nerve signals and plays a role in reflex actions.

What are the main components of the central nervous system?

• Heart and lungs

• Stomach and intestines

• Brain and spinal cord

• Liver and kidneys

Describe the functions of the brain in the central nervous system.

• Produces digestive enzymes

• Regulates body temperature

• Pumps blood throughout the body

• Controls and coordinates bodily functions, processes sensory information, responsible for thoughts, emotions, and memories
