Musculoskeletal Definitions Flashcards
Lateral movement of a body part away from the midline of the body
Abduction
Lateral movement of a body part toward the midline of the body
Adduction
In a standing and sitting position a straight line can be drawn from the ear through the shoulder
and hip. In bed, the head, shoulders, and hips are aligned.
Alignment
The rounded head of one bone fits into a cuplike cavity in the other. (Shoulder and hip joints) Flexion, extension, abduction, adduction, and rotation can occur.
Ball + Socket Joint
Non-vascular connective tissue found in the joints as well as in the nose, ear, thorax, trachea, and
larynx.
Cartilage
Movement of the distal part of the limb to trace a complete circle while the proximal end of
the bone remains fixed. Example: The leg is outstretched and moved in a circle.
Circumduction
The oval head of one bone fits into a shallow cavity of another bone. (Wrist joint)
Flexion, extension, abduction, and adduction can occur.
Condyloid Joints
Backward bending of the hand or foot.
Dorsiflexion
Movement of the sole of the foot outward (occurs at the ankle).
Eversion
The state of being in a straight line
Extension
A body part turning on its axis away from the midline of the body.
External Rotation
Thin bones that contribute to shape. The ribs and several of the skull bones are flat bones.
Flat Bones
The state of being bent
Flexion
The manner or style of walking. Normal finding: head erect, vertebrae straight, knees and feet point forward, arms at side with elbows flexed, arms swing freely in alteration with leg swings.
Gait
Articular surfaces are flat. (Carpal bones of wrist and tarsal bones of feet) Flexion, extension, abduction and adduction can occur.
Gliding Joint
Refers to weakness of one half of the body.
Hemiparesis
Paralysis of one half of the body.
Hemiplegia
A spool-like surface of one bone fits into a concave surface of another bone. (Elbow, knee, and
ankle joints) Only flexion and extension can occur.
Hinge Joint
