Muscles Chpt 9

Mblex Study Guide

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
