The principle that states the entire motor unit is either turned on or off is the:

• Law of facilitation

• Hooke's Law

• All or none principle

• Arndt-Shcultz Principle

The law of specificity of nervous energy states that:

• The stress used to stretch or compress a body is proportional to the strain experience

• The excitation of a receptor always gives rise to the same sensation regardless of the nature of the stimulus

• The anterior spinal nerve roots are motor and posterior nerve roots are sensory

• If stimulation is sufficiently increased, motor reaction is manifested on both sides

The principle that states that a nerve truck supplies a joint also supplies the muscle of the joint and skin over the insertions of the muscle is called:

• Hilton's Law

• The law of Generalization

• Weber's Law

• The Law of temporal summation

The law of facilitation states that:

• When an impulse passes through a specific set of neurons to he exclusion of others, it tends to take the same course on future occasions

• If a mild irritation is applied, the movement will take on one side only, on the side that has been irritated

• The sensitivity of the sensory system to differences depends on the absolute strength of the stimuli

• When the irritation becomes really intense, it radiates to all part of the spinal cord causing general contractions of muscles

The principle of Thixotropy describes:

• Elastic muscles

• Solid bone

• Stiff connective tissue

• Gel-like fascia

The property that describes the elastic and viscous properties of tissue is called

• Viscosity

• Velocity

• Viscoelasticity

• Elasticity

The ability of an inorganic or organic substance to generate an electric charge from mechanical deformation is called:

• Action potential

• Electricity

• Polarity

• Piezoelectricity

The property that maintains the upright structure of the skeleton against gravity and provides the tension necessary to create movement is called:

• Integrity

• Viscoelasticity

• Tensegrity

• Thixotropy

The restriction of blood supply which results in the dysfunction of tissue is called:

• Compression

• Ischemia

• Entrapment

• Neuropraxia

_______________ refers to when there is pressure on a nerve caused by a bone, cartilage, or soft tissue.

• Trigger point

• Hypertonus

• Nerve entrapment

• Tender point
