Question at position 55 asks which property of muscle tissue enables it to respond to a stimulus, such as a hormone or motor neuron signal. 
Option 1: Contractility. While contractility refers to the ability of muscle fibers to shorten and generate force, this property is about the outcome of activation rather than the initial responsiveness to a stimulus. It is a consequence of excitability and the biochemical processes that follow activation.
Option 2: Elasticity. Elasticity describes the ability of tissue to return to its original shape after being stretched. This property is about deformation and recoil, not about sensing or responding to a stimulus from nerves or hormones.
Option 3: Excitability. Excitability is the capacity of muscle (and other excitable tissues) to respond to a stimulus—such as a neurotransmitter or hormone—by generating an electrical impulse or action potential that triggers downstream events leading to contraction. This property directly accounts for the tissue’s responsiveness to signals.
Option 4: Extensibility. Extensibility refers to the ability of a tissue to be stretched or extended beyond its resting length. While important for function, it describes a mechanical capability rather than the initial detection and response to an external signal.
In summary, among the listed properties, the one that most accurately describes the ability to respond to a stimulus like a hormone or motor neuron signal is the property that denotes a tissue’s responsiveness to such stimuli, i.e., excitability. The other properties describe mechanics or outcomes of activation rather than the initiating responsiveness.
