Understanding Neuron Functions and Structure

What is the primary function of sensory neurons?

• To carry messages from the central nervous system to muscles

• To carry messages from the peripheral nervous system to the brain and spinal cord

• To transfer messages between relay neurons

• To insulate axons

Which type of neuron is responsible for transferring messages from sensory neurons to motor neurons?

• Sensory neurons

• Motor neurons

• Relay neurons

• Axons

What is the role of the nucleus in a neuron?

• To receive nerve impulses from adjacent neurons

• To act as the control centre of the cell

• To insulate the axon

• To transmit nerve impulses between neurons

Which part of the neuron receives nerve impulses from adjacent neurons?

• Axon

• Myelin sheath

• Dendrite/dendrons

• Synapse

What is the function of the myelin sheath?

• To carry messages to muscles

• To protect the axon from external influences

• To transfer messages between neurons

• To act as the control centre of the cell

Which part of the neuron is responsible for transmitting nerve impulses between two nerve cells?

• Axon

• Synapse

• Nucleus

• Dendrite/dendrons

What is the primary function of motor neurons?

• To carry messages from the peripheral nervous system to the brain

• To transfer messages between relay neurons

• To carry messages from the central nervous system to muscles/glands/organs

• To insulate the axon

Which part of the neuron is responsible for the travel of electrical signals?

• Synapse

• Dendrite/dendrons

• Axon

• Nucleus

What is the role of relay neurons in the nervous system?

• To carry messages from the central nervous system to muscles

• To transfer messages from sensory neurons to other relay or motor neurons

• To insulate the axon

• To act as the control centre of the cell

Which of the following is NOT a type of neuron?

• Sensory neuron

• Motor neuron

• Relay neuron

• Synaptic neuron
