Document Summary
Anatomical position: person stands erect, feet together (or slightly apart), eyes forward, palms facing forward. Medial: toward midline of body; on the inner side. Lateral: away from midline of body; on outer side. Proximal: closer to origin of a body part or point of attachment of limb to body trunk. Distal: further from origin of a body part or point of attachment of limb to body trunk. Anterior (ventral): toward or at front of body; in front of. Deep: more internal; away from the body surface. The axial structures include the head, neck, and trunk (thorax, abdomen, pelvis): cephalic (head), cervical (neck), thoracic (chest), abdominal (belly), pelvic (hips), pubic (genital). The appendicular structures include the limbs and extremities: arm (brachial), forearm (antebrachial), carpus (wrist), manus (hand), thigh (femoral), leg (crural), pedal (foot), tarsal (ankle). Sagittal plane: vertical, divides body into right and left parts. The median plane (midsagittal) runs down the very middle of the body.
