Question | Answer |
A muscle that causes or controls joint motion through a specific plane; also known as a mover | Agonist |
The property of a muscle fiber contraction by which, when contraction is initiated, the fiber contracts to its full ability or does not contract at all | All-or none response |
A muscle usually located on the opposite side of a joint from the mover and having the opposite action. | Antagonist |
A broad, flat sheet of fibrous connective tissue | Aponeurosis |
A contraction in which the muscle shortens with tone because it's contractile force is greater than the opposing force at the attachments of the muscles. | Concentric Action |
The ability of a muscle to shorten forcibly with adequate stimulation | Contractility |
Force applied to an object that produces movement in or of the object | Dynamic Force |
The ability of a muscle to recoil and resume it's original resting length after being stretched | Elasticity |
The ability of a muscle to receive and respond to a stimulus | Excitability |
The ability of a muscle to be stretched and extended | Extensibility |
A fibrous or loose type of connective tissue that covers supports and separates muscles | Fascia |
A stabilizing muscle located at a joint or body part that contracts to fix or stabilize an area. | Fixator |
The attachment of a muscle that moves when the muscle contracts. It is usually the distal attachment for a muscle. | Insertion |
A contraction in which the muscle stays the same length with tone because it's contractile force equals that of the opposing force at the attachments of the muscle | Isometric Action |
The action of the muscle that occurs when tension develops in the muscle while it shortens and lengthens | Isotonic Action |
The point at which all motor units of a muscle have been recruited and the muscle is unable to increase in strength | Maximal Stimulus |
A motor neuron and all of the muscle fibers it controls | Motor Unit |
The attachment of a muscle that does not move when the muscle contracts. Is usually the proximal attachment of the muscle. | Origin |
The extra amt of oxygen that must be take in to remove the buildup of lactic acid from anaerobic respiration of glucose to convert to lactic acid. | Oxygen Debt |
The state of tension in resting muscles | Resting tone |
When a muscle contracts and the attachment that normally stays fixed moves, and the attachment that usually moves stays fixed | Reverse action |
Force applied to an object in such a way that it does not produce movement | Static Force |
Movers of a joint other than the prime mover that is an assistant, secondary, emergency movers. Any muscle that helps an action occur | Synergist |
The stimulus at which the first observable muscle contraction occurs. | Threshold Stimulus |
A hyper-irritable locus within a taut board of skeletal muscle located in the muscular tissue or it's associated fascia | Trigger point |
What are the three types of muscle in the body? | Skeletal, Cardiac & Smooth |
The capacity to do work | Energy |
What are the 4 main functions of muscles? | 1. Produce mvmt 2.stabilize joints 3.maintain posture 4.generate heat |
A syndrome w symptoms of widespread pain or aching, persistant fatigue, generalized morning stiffness, nonrestorative sleep & multiple tender points. | Fibromyalgia |
An inflammation of the plantar fascia and surrounding myofascial structures. Caused by excessive stress on the foot. | Plantar Fasciitis |
An inflammation of the proximal portion of any musculotendinous structures originating from the lower part of the tibia. | Shin Splints |
An injury to the soft tissues of the neck caused by sudden hyperextension or flexion. | Whiplash |
