Detailed explanation-1: -The ability of an organism or organ to detect external stimuli, so that an appropriate reaction can be made, is called sensitivity (excitability).
Detailed explanation-2: -Excitability is the ability to respond to a stimulus, which may be delivered from a motor neuron or a hormone. Extensibility is the ability of a muscle to be stretched.
Detailed explanation-3: -The ability of an organism to respond to external stimuli is called sensitivity.
Detailed explanation-4: -Irritability is the ability to respond to a stimulus by initiating a nerve impulse. Irritability is one of the major characteristics of the neurons or nerve cells, which are the functional units of the nervous system.
Detailed explanation-5: -Excitability-ability to respond to stimuli; Contractibility-ability to contract; Extensibility-ability of a muscle to be stretched without tearing; Elasticity-ability to return to its normal shape.
