Detailed explanation-1: -Lateral-away from the midline of the body (example, the little toe is located at the lateral side of the foot). Proximal-toward or nearest the trunk or the point of origin of a part (example, the proximal end of the femur joins with the pelvic bone).

Detailed explanation-2: -Lateral means to the side of, or away from, the middle of the body. Examples: The ears are lateral to the nose. The arms are lateral to the chest.

Detailed explanation-3: -The term medial is the opposite of lateral, and denotes how close a structure is to the median plane of the body. For example, the ear is lateral to the eye, which is in turn lateral to the nose.

Detailed explanation-5: -Bilateral (from Latin bis ‘twice’): on both sides of the body. For example, bilateral orchiectomy means removal of testes on both sides of the body.
