Contrecoup brain injury: after head is struck, brain continues to move within the skull and becomesinjured on the side opposite the forceContusion: a bruiseConvection: transfer of thermal energy indirectly through another medium such as air or liquidConversion: transfer of thermal energy by other forms of energy such as electricityConvulsion: paroxysm of involuntary muscular contraction and relaxationCrepitation: a crackling sound heard during movement of body part or joint; related to inflammation orfractured boneDebride: remove dirt and dead tissue from a wound; smooth or clean damaged tissueDegeneration: deterioration of tissueDiaphragm: a musculomembranous wall separating the abdomen from the thoracic cavityDiastolic blood pressure: the residual pressure when the heart is relaxed (in between beats)Distal: furthest away from the point of reference or midline of the bodyDorsiflexion: bending toward the dorsum or rear, opposite of plantar flexionDressing: a material, such as gauze, applied to a wound (held in place with a bandage)Duration: length of timeEccentric: muscle contraction by lengthening of the muscleEcchymosis: skin discoloration due to hemorrhageEctopic: located in an abnormal placeEdema: swelling; collection of fluid as resultElectrolyte: solution that is a conductor of electricity; important to proper hydration (i.e. sodium andpotassium)Electrotherapy: treating a disease by electrical devicesEndurance: ability to undergo prolonged physical demandEpiphysis: the cartilaginous growth region of a boneEtiology: pertaining to the cause or origin of a conditionEversion: (of the ankle) to abduct the foot, stressing medial tissues of the ankleFascia: fibrous membrane that covers, supports, and separates musclesFasciitis: inflammation of the fasciaFrequency: number of times (i.e. twice per week)Genu recurvatus: hyperextension of the kneeGenu valgum: knock kneesGenu varum: bow legsHeat exhaustion: a condition characterized by faintness, rapid pulse, nausea, profuse sweating, coolskin, and collapse, caused by prolonged exposure to heat accompanied by loss of adequate fluid and saltfrom the bodyHeat stroke: a disturbance of the temperature-regulating mechanisms of the body caused byoverexposure to excessive heat, resulting in fever, hot and dry skin, and rapid pulse, sometimesprogressing to delirium and comaHematoma: blood tumor or massHemoglobin: oxygen carrying pigment of red blood cells; give blood its red colorHemophilia: a hereditary blood disease in which coagulation is greatly prolongedHemorrhage: discharge of bloodHemothorax: bloody fluid in the pleural cavityHyperextension: stretching of a joint beyond its normal extensionHyperflexibility: soft tissue flexibility beyond a joint’s normal range without forceHypermobility: mobility or instability of a joint involving insufficient soft tissue or bony supportHyperthermia: abnormally high body temperature

Hypertension: high blood pressure; abnormally high tensionHypertrophy: enlargement of a tissue caused by increased cell sizeHyperventilation: abnormally rapid and deep breathing that cannot be controlled; causes a decrease incarbon dioxide, fall in blood pressure and faintingHypoallergenic: produces lower amount of allergensHypotension: low blood pressureHypothermia: abnormally low body temperatureHypoxia: lack of an adequate amount of oxygenInjury: an action that causes damage or painInnervation: nerve distribution throughout a body partIntensity: magnitude of energy or force; workloadInterosseous membrane: connective tissue membrane between two parallel bonesIntervertebral: between two vertebraeIntramuscular bleeding: bleeding within a muscleIntravenous: describes a method of administering substances via a veinInversion: (of the foot and ankle) adduction of the foot stressing the tissues on the lateral side of theankleIschemia: local anemiaIsokinetic: describes muscle contraction with a resistance depending on the magnitude of force appliedby the athlete and speed remaining constantIsometric: describes contraction with no change in muscle lengthIsotonic: describes contraction that shortens and lengthens the muscleJoint: articulation of two or more bonesJoint capsule: saclike structure that encloses the articulating ends of bones and some related soft tissuestructuresKeloid: an overgrowth of collagenous scar tissueKyphosis: exaggeration of the normal curve of the thoracic spineLaceration: a rough, jagged tear of the skinLateral: point of reference away from the saggital midline of the bodyLiability: the legal responsibility to perform an act in a reasonable and prudent mannerLigament: connective tissue with no contractile qualities that connects bone to bone and acts as asupport against excessive joint motionLordosis: Abnormal exaggerated curve of the lumbar spine.Medial: point of reference closest to the saggital midline of the body.Muscle: tissue that, when stimulated, contracts and produces motion around a jointMuscle contracture: abnormal shortening of a muscle in which there is great resistance toward passivestretchMuscular endurance: ability to perform repetitive muscular contractions against some resistanceMuscular strength: maximum force that can be produced by a muscle during a single contractionMusculoskeletal: pertaining to muscles and the skeletonNecrosis: death of tissueNegligence: failure to use ordinary or reasonable care or perform a standard, necessary actionNerve entrapment: a nerve that is compressed between bone or soft tissueNeuroma: a tumor formed of nerve tissueNon-contact sport: any sport that does not place athletes in regular physical contactNystagmus: a constant involuntary movement of the eyeball up and down or back and forthOpen fracture: any fracture that involves penetration of bone through superficial tissues
