Document Summary
Ecchymosis discoloration of the skin: bruising. Hematoma - swelling of clotted blood in tissues. Ectopic calcification deposits of calcium salts in tissues or bones. Aponeurosis formed by dense, regular connective tissue: strong, flat, sheet like tissues that attach muscles to other muscles or bones. Afferent and efferent nerves afferent send info to the brain, efferent away. Neuroma tumor growing from a nerve. Hyperesthesia excessive sensitivity (opposite of numb) Paresthesia abnormal sensation: tingling or prickling. Anisotropic structure is stronger in resisting force from one direction compared to others: ex. Lateral ankle sprains are more common than medial because of this. Axial force force acting along the vertical part of a structure: ex. Acute trauma single force produces an injury: causative force is metrotrauma. Chronic injury (stress injury) repeated or chronic loading over time produces injury: causative force is microtrauma. Viscoelastic fashion both elasticity and time-dependent extensibility. Elasticity ability to return to normal length. Irritability ability to respond to a stimulus.
