Explanation: The neuron is the basic structural and functional unit.
Question 3 of 15
The long fibre of a neuron that carries the signal away is the:
Dendrite
Axon

Question 11 of 15
A quick automatic response such as pulling the hand from a hot object is a:
Reflex action
Voluntary action
Hormonal action
Memory
Explanation: This is a reflex action, processed by the spinal cord.
Question 12 of 15
The correct order of the reflex arc is:
Receptor → sensory neuron → spinal cord → motor neuron → effector
Effector → motor neuron → brain
