Neuron Structure

What is the resting potential of a neurone?

• The electrical charge difference across the neurone's membrane when it is not actively transmitting a signal.

• The maximum voltage reached during an action potential.

• The average voltage of a neurone during synaptic transmission.

• The voltage difference when a neurone is fully depolarized.

What is the role of sensory neurones?

• To carry signals from sensory receptors to the central nervous system.

• To transmit signals from the central nervous system to muscles.

• To process information within the brain.

• To connect different sensory organs to each other.

What is the axon terminal?

• The part of the neuron that receives signals from other neurons.

• The endpoint of an axon where neurotransmitters are released to communicate with other neurones.

• The protective covering of the axon that speeds up signal transmission.

• The structure that connects the neuron to the muscle or gland it controls.

What is the nucleus of a neurone?

• The part of the neurone that transmits signals to other cells.

• The control centre of the neurone, containing the cell's genetic material and regulating its activities.

• The outer layer of the neurone that protects it from damage.

• The structure that connects the neurone to the muscle fibers.

What is the function of neurotransmitters?

• To transmit signals across the synapse from one neurone to another.

• To protect neurons from damage.

• To store genetic information.

• To provide energy to the brain.

What is a stimulus?

• A type of food that provides energy to organisms.

• A change or signal in the environment that can provoke a reaction from an organism.

• A method of communication between organisms.

• A physical barrier that prevents interaction with the environment.

How do neurones communicate with each other?

• Through electrical impulses and chemical signals at the synapse.

• By direct contact between their membranes.

• Using only electrical impulses without chemical signals.

• Through the release of hormones into the bloodstream.

What is the function of dendrites in a neurone?

• Dendrites transmit electrical impulses away from the neurone.

• Dendrites are the parts of the neurone that receive messages from other neurones.

• Dendrites protect the neurone from damage.

• Dendrites are responsible for the production of neurotransmitters.

What is the function of interneurons?

• Interneurons connect sensory and motor neurones and process information within the central nervous system.

• Interneurons transmit signals from the brain to the muscles.

• Interneurons are responsible for the production of hormones.

• Interneurons are involved in the formation of new memories.

What is the cell body of a neuron?

• The part of the neuron that contains the nucleus and organelles, responsible for maintaining the life of the neuron.

• The long projection that transmits signals away from the neuron.

• The small gaps between neurons where neurotransmitters are released.

• The protective covering that insulates the axon of the neuron.
