Monosynaptic: Occurs when there are only two neurons present in the reflex arc; a single synapse occurs within the gap between the two neurons (i.e., patellar tendon reflex).

Morbidity: Refers to being affected by a disease, but not dying from it.

Mortality: Refers to deaths resulting from a disease.

Motor End Plate: The distal component of the motor neuron that transmits the neural impulse to the muscle. 

Multiple Sclerosis (MS): A neurological disorder in which there is demyelination of the central nervous system. This disorder can cause changes in sensation, muscle weakness, visual problems, and problems with coordination and balance.

Muscle Spindles: The main sensory component of a muscle; the spindle is sensitive to both quick and sustained stimulation. 

Muscle Stretch Reflex: When a muscle is stretched, there is a reflexive contraction of that muscle to shorten. 

Neuropathy: Any type of disease involving nerves.

Neutral Position: The position of a joint that permits a maximum amount of joint mobility and laxity.

Paralysis: The complete or partial loss of function of an affected body part.

Peripheral Nervous System: Is composed of the 12 pairs of cranial nerves and the 31 pairs of spinal nerves. This system can be further subdivided into the autonomic and somatic nervous systems. 

Proximal: Closer to the center/midline of the trunk when compared to another part; the opposite of distal (i.e., the hip is more proximal to the trunk than the ankle).
