Assertion : Neurons are said to possess the property of excitability.
Reason : Neurons can get excited by a given stimulus.
Neurons are the cells of nerve tissue which are highly specialised for receiving and conducting the messages or information from one part of the body to another. Any change inside or outside the body acts as stimulus and initiate their activity. For a given stimulus, neurons can be excited and this excitement is passed along the nerve fibers to the specific organs, in the form of a nerve impulse. This property of neurons is called excitability.
