The rotator cuff muscles include ____
Teres minor, subscapularis, supraspinatus, and infraspinatus
The study of the muscular system.
Muscles also called striated (striped) are referred to as voluntary muscles because they enable conscious movements.
Non striated (striped) muscles that contract involuntarily; they line various internal organs and blood vessels.
Muscle found only in the heart and is striated (striped) but also contracts involuntarily.
The point where the muscle attaches to the stationary bone. It is usually closest to the trunk of the body, or proximal.
The mid-portion of the muscle, or fleshy part between the insertion and origin.
The prime mover that is the main muscle that contracts to perform an action.
The opposing muscle that stretches and yields to the actions of the agonist.
Another term for connective tissue.
What fascia keeps the muscles separated from the skin?
Which fascia holds in body temperature and serves as muscle protection.
Which fascia lines the body walls and related muscles together in addition to carrying blood and lymph vessels?
The outer layer of the muscle that covers the whole muscle.
The center layer of the muscle that surrounds muscle fibers that are separated into groups of fascicles.
Muscle fibers that are separated into groups of 10 to more than 100.
The thin sheet of connective tissue that surrounds the inside of each fascicle and separates the individual muscle fibers.
What each individual muscle fiber in composed of.
Cords of thick tissue that serve as the attachments between skeletal muscle and bone.
A connective tissue that stretches over a broad, flat area, such as on the heel or the top of the head.
The ability for muscle tissue to respond to stimuli by producing electrical signals.
The ability for muscle tissue to contract when stimulated by a nerve signal.
The ability for muscle tissue to stretch without being damaged.
The ability for muscle tissue to return to its original shape and length after it has been contracted or extended.
A gap between a motor neuron and a muscle fiber where nerve signals are transmitted.
The three proteins that muscles are made of.
What is the synapse known as?
Muscle fibers that are tiny and contract slowly. They are capable of prolonged contraction - for instance, enabling us to stand for hours.
Muscle fibers that are larger in diameter and can produce the most powerful contractions, but fatigue quickly.
An alternating pattern of motor units being active and inactive, resulting in keeping the muscle firm without causing any action causes _____
A characteristic of muscle fibers where the stimulus must be strong enough to excite the entire fiber - or none of the muscle will react.
Action where the bone (and muscle) is coming closer to the midline.
Action where the bone (and muscle) is moving away from the midline.
Decreasing the angle of a joint.
Movement turning inward.
Movement turning upward.
Movement turning downward.
A muscle that moves bone away from the midline.
A muscle that moves bone closer to the midline.
The main muscle that contracts to perform an action; also known as the prime mover.
The opposing muscle that stretches and yields to the the agonist.
Muscle having two heads.
A muscle that turns inferiorly or posteriorly.
A muscle that produces inferior motions.
A muscle that decreases the angle of a joint.
A muscle that contracts to stabilize intermediate joints to either help prevent unwanted movements or aid the movement of the agonist.
Stretching or tearing of a ligament.
Tearing of a muscle itself and is usually less serious.
A general term that refers to any disease of the muscle.
A progressive weakening of the muscle caused by degenerating neurons.
A collective term for diseases that cause a progressive loss of muscle fibers without any nervous system involvement.
A benign tumor composed of muscle tissue.
Inflammation of the muscle.
When muscle tissue accumulates calcium deposits and begins to harden.
A permanent shortening of a muscle
A permanent shortening of a muscle caused by damaged or destroyed muscle fibers being replaced by scar tissue, usually caused by a lack of circulation from some outside interference such as cast or elastic bandage that is too tight.
A painless thickening of the fascia in the palm of the hand that results in the inability to move the digits.
Tender areas of hyperirritability that cause sensations to be referred to an area outside of the specific tenderness.
Damage to muscle caused by environmental toxins or by a failure of the body to metabolize certain nutrients; not a genetic condition.
Acquired metabolic and toxic myopathies
Another term for shin splints.
Anterior compartment syndrome
A chronic condition characterized by severe chronic fatigue of six months or longer duration. Linked to the Epstein-Barr virus.
Chronic fatigue syndrome
An unusually painful muscle contraction.
Muscles that are weak, lax or soft
A protrusion of an organ or other tissue through an abnormal opening in the wall of the cavity normally containing it, or in the soft tissue.
Inflammation of the plantar fascia on the sole of the foot; very painful.
An acute viral disease that can end in permanent muscle atrophy and contracture.
A neuromuscular syndrome that may develop years after recovering from polio.
A tear in one of the rotator cuff muscles.
Rotator cuff tear
Tenderness, swelling and pain of the anterior leg muscles.
A condition characterized by increased muscle tone in which abnormal stretch reflexes intensify muscle resistance to passive movements.
Inflammation of tendons and muscle attachments.
Inflammation of the tendon sheath (covering).
