Nervous System Quiz

What is the main function of the nervous system?

• Respiration

• Communication

• Digestion

• Circulation

Which type of neurons carry signals from receptors to the spinal cord and brain?

• Sensory Neurons

• Relay Neurons

• Intermediate Neurons

• Motor Neurons

What are the three main components of neurons?

• Dendrites, Nucleus, Cell Body

• Dendrons, Axons, Synapses

• Nucleus, Synapses, Receptors

• Cell Body, Axons, Dendrites

What is the function of dendrites in a neuron?

• Generate electrical signals

• Receive information from other neurons

• Insulate the axons

• Carry the signal away from the cell body

What is the purpose of synapses in the nervous system?

• Speed up the rate of conduction

• Connect two or more adjacent neurons

• Detect the stimulus

• Trigger the response

Which type of neuron triggers the response in the nervous system?

• Relay Neurons

• Motor Neurons

• Intermediate Neurons

• Sensory Neurons

What happens at a synapse between two adjacent neurons?

• Receptors detect the stimulus

• Speed of the signal is controlled

• Release of neurotransmitter triggers a new electrical signal

• Nerve signals travel in both directions

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

• Detect the stimulus

• Make connections with other neurons

• Carry signals from receptors to the spinal cord and brain

• Trigger effectors to provide a response

Which component of a neuron carries the signal away from the cell body?

• Nucleus

• Dendrites

• Axons

• Dendrons

What is the function of relay neurons in the central nervous system?

• Trigger effectors to provide a response

• Carry messages from one part of the central nervous system to another

• Carry signals from receptors to the spinal cord and brain

• Detect the stimulus
