Anatomical position is the starting position for body segment movements, characterized by an upright standing position, facing forward, legs together, feet flat on the floor, and hands at the side with palms facing forward
Anatomical directional terms help describe the body's 'geography' and how components relate to each other, including terms like anterior, posterior, inferior, superior, medial, lateral, proximal, and distal
Anatomical reference planes include the frontal (coronal), transverse (horizontal), and sagittal (median) planes, dividing the body in half by mass
Anatomical reference axes are imaginary lines passing through joints, with three axes perpendicular to specific cardinal planes: mediolateral, anteroposterior, and longitudinal axes
Fundamental movements in the body occur in different planes of motion, such as sagittal, frontal, and transverse planes, each around a specific axis
Movements in the sagittal plane about the mediolateral axis include flexion, extension, plantar flexion, and dorsiflexion
Movements in the frontal plane about the anteroposterior axis include abduction and adduction, as well as eversion, inversion, and lateral flexion
Movements in the transverse plane about the longitudinal axis include rotation movements like internal/external rotation and pronation/supination
