General definition: The study of (movement). Major Divisions of Human Body Major Divisions of Human Body (ch1.1) Axial body Appendicular body Major Body Parts (ch1.2) Major Body Parts (ch1.2) Spatial Terms (ch.2) Spatial Terms (ch.2) Directional terms Anterior­posterior, medial­lateral, superior­ inferior, proximal­distal, superficial­deep Spatial Terms (ch.2) Spatial Terms (ch.2) Planes and axes for body movement Sagittal plane & transverse axis Frontal plane & anteroposterior axis Transverse plane & longitudinal axis Forms of Motion Forms of Motion Linear motion (translation) Rectilinear and curvilinear Forms of Motion Forms of Motion Angular motion (rotation) Fixed axis of rotation Forms of Motion Forms of Motion General motion : Combination of linear and angular motion Joint Movement (ch5.10­5.25) Joint Movement (ch5.10­5.25) Sagittal plane movements Flexion & extension and dorsiflexion, & plantarflexion, anterior tilt & posterior tilt Frontal plane movement Adduction & abduction, lateral flexion, inversion & eversion, and ulnar & radial deviation Transverse plane movement Left & right rotation, medial & lateral rotation, pronation & supination, and horizontal adduction (flexion) & abduction (extension) Scapular plane (scaption) movement Elevation & depression, protraction & retraction, upward rotation & downward rotation Joint Movement Joint Movement Hyperextension Circumduction Oblique plane movements Reverse actions Vector Composition (ch5.30) Vector Composition (ch5.30) Vector vs. Scalar Resultant vector “Tip­to­tail” (triangular) vector composition Resultant vector Vector #2 Vector #1 Vector Composition (ch5.30) Vector Composition (ch5.30) Mechanical Load Mechanical Load Compression: (pushing) force directed axially through a body Tension: (pulling) force directed axially through a body Shear: force directed (parallel) to a surface Bending: (asymmetric) loading Torsion: (twisting) force around its longitudinal axis Kinetic Concepts Kinetic Concepts Torque Pressure (Stress) ...
