Eccentric tension - ANSWER: A type of muscle tension that helps control the speed
and direction of movement.
Isotonic contraction - ANSWER: A type of muscle contraction that results in
movement, such as raising or lowering a body part.
Concentric tension - ANSWER: Increased muscle contraction that causes muscle
shortening, resulting in movement.
Isometric contraction - ANSWER: A static contraction that causes an increase in
muscle tension without shortening or active movement of the muscle.
Scoliosis - ANSWER: A structural curvature of the spine associated with vertebral
rotation.
Osteogenesis imperfecta - ANSWER: An inherited disorder that makes bones porous,
short, bowed, and deformed.
Osteomalacia - ANSWER: An uncommon metabolic disease characterized by
inadequate and delayed mineralization, resulting in compact and spongy bone.
Arthritis - ANSWER: An inflammatory joint disease characterized by inflammation or
destruction of the synovial membrane and articular cartilage.
Joint degeneration - ANSWER: Changes in articular cartilage combined with
overgrowth of bone at the articular ends, commonly affecting weight-bearing joints.
Base of support - ANSWER: The area beneath an object or person that includes every
point of contact that the object or person makes with the supporting surface.
Center of gravity - ANSWER: The point at which the body's mass is evenly distributed
in all directions.
Lumbar muscle group - ANSWER: The group of muscles around the lumbar vertebrae
that are commonly injured by twisting during the lifting of patients.
Synovial joints - ANSWER: Freely movable joints that are the most mobile, numerous,
and anatomically complex body joints.
, Fibrous joints - ANSWER: Joints that fit closely together and are fixed, permitting
little, if any, movement.
Cartilaginous joints - ANSWER: Joints that have little movement but are elastic and
use cartilage to unite separate bony surfaces.
Proprioception - ANSWER: The awareness of the position of the body and its parts.
Semicircular canals - ANSWER: Three fluid-filled structures in the inner ear that help
maintain balance.
Weight-bearing joints - ANSWER: Joints that are commonly affected by degenerative
changes due to joint degeneration.
Inflammatory joint disease - ANSWER: A condition characterized by inflammation or
destruction of the synovial membrane and articular cartilage.
Static contraction - ANSWER: Another term for isometric contraction, where there is
no shortening or active movement of the muscle.
Dynamic contraction - ANSWER: Muscle actions that involve movement, including
both concentric and eccentric contractions.
Quadriceps set exercises - ANSWER: Exercises that involve instructing the patient to
tighten and relax the quadriceps muscle group.
Pelvic floor exercises - ANSWER: Exercises aimed at strengthening the pelvic floor
muscles.
Health Promotion and Maintenance - ANSWER: A nursing focus area that includes
strategies to maintain health and prevent disease.
Physiological Adaptation - ANSWER: The body's ability to adjust to changes in the
environment or internal conditions.
Assessment - ANSWER: The process of collecting and analyzing information about a
patient's health status.
Teaching/Learning - ANSWER: The process of imparting knowledge and skills to
patients to promote health and manage illness.
Isotonic exercises - ANSWER: Dynamic exercises involving muscle movement and
contraction.
Examples of isotonic exercises - ANSWER: Walking, swimming, jogging, dance
aerobics, bicycling.
