Pathology of the Muscular System Flashcards
Fasciitis
The inflammation of a fascia
Fibromyalgia
A debilitating chronic condition characterized by fatigue; diffuse or specific muscle, joint, or bone pain; and a wide range of other symptoms
Tenosynovitis
An inflammation of the sheath surrounding a tendon
Tendinitis/tendonitis/tenonitis
An inflammation of the tendon caused by excessive or unusual use of the joint
Chronic fatigue syndrome (CFS)/Myalgic encephalomyelitis
A disorder of unknown cause that is characterized by profound fatigue that is not made better by bedrest, and can be made worse by physical or mental activity. Symptoms are similar to those of fibromyalgia.
Adhesion
A band of fibrous tissue that holds structures together abnormally. Adhesions can form in muscles or in internal organs, as the result of an injury or surgery.
Atrophy
Weakness or wearing away of body tissues or structures. Can be caused by pathology or a misuse of a muscle over a long period of time.
Myalgia
Tenderness or pain in the muscles
Myocele
The herniation of muscle substance through a tear of the fascia surrounding it
Myolisis
The degeneration of muscle tissue
Myorrhexis
The rupture or tearing of a muscle
Polymyositis
A muscle disease characterized by the simultaneous inflammation and weakening of voluntary muscles in many parts of the body. The muscles in the trunk and torso are most often affected
Rhabdomyolysis
A serious syndrome that can result from a direct or indirect muscle injury. The death of muscle fibers releases their contents into the bloodstream, where they can lead to complications such as renal failure.
Sarcopenia
The loss of muscle mass, strength, and function that come with aging. A weight or resistance training program can significantly improve muscle mass and slow, but not stop, this process.
Muscle tone
The state of balanced muscle tension (contraction and relaxation) that makes normal posture, coordination, and movement possible
Atonic
Lacking normal muscle tone or strength
Dystonic
A condition of abnormal muscle tone that causes the impairment of voluntary muscle movement
Hypotonia
A condition in which there is diminished muscle tone of the skeletal muscles
Ataxia
The lack of muscle coordination during voluntary movement. These movements, which are often shaky and unsteady, are most frequently caused by abnormal activity in the cerebellum.
Contracutre
A permanent tightening of the fascia, muscles, tendons, ligaments, or skin that occurs when normally elastic connective tissues are replaced with nonelastic fibrous tissues. The most common causes of contractures are scarring or the lack of use due to immobilization or inactivity.
Intermittent claudication
Pain in the leg muscles that occurs during exercise and is relieved by rest. This condition is caused by poor blood circulation and is associated with peripheral vascular disease.
Spasm
Any sudden, involuntary contraction of one or more muscles
Tic
A repeated spasm, often involving the eyelids or face. These movements are difficult or impossible to control.
Myoclonus
The quick, involuntary jerking of a muscle or group of muscles. This may occur normally as a person is falling asleep, as a result of epilipsey, a metabolic condition, or as a reaction to a medication.
