• Abducting structure (archaic) — An old or regional anatomical term previously used to describe a muscular structure, ligament, or shunt canal that causes a deviation, abduction, or direction change of a physiological flow or a body segment. In early translations of medical textbooks and dissection treatises into Romanian, the word was employed as an equivalent for abductor muscles (which move a limb away from the body's midline).
• abs — (Automotive) An electronic automotive safety system that prevents vehicle wheels from locking during heavy braking, maintaining steering control; (sports, anatomy, colloquial) short form for abdominal muscles.
• Forearm — The segment of the upper limb located between the elbow joint and the wrist joint, having the radius and ulna bones as its skeletal base. This anatomical segment houses complex muscle groups that control pronation, supination, as well as the flexion and extension of the fingers and hand, being essential for fine motor skills.
• Apodemes — Internal ingrowths or ridges of the arthropod exoskeleton that serve as structural supports and provide solid points of attachment and leverage for locomotory muscles; internal cuticular projections. These chitinous formations fulfill the function of a functional endoschelet, being essential for the biomechanics of insect and crustacean movement.
