Document Summary
Articulations: articulations, where two bones interconnect, immovable joints, synarthroses, or bony, slightly moveable joints, amphiarthroses, or fibrous / cartilagenous, freely moveable joints, diarthroses, or synovial. Amphiarthroses (slightly movable joints: two major types, syndesmosis = bones connected by a ligament, symphysis = bone separated by fibrocartilage. Diarthroses (freely movable joints: bony surfaces enclosed within articular capsule, bony surfaces covered by articular cartilage, bony surfaces lubricated by synovial fluid, structures include, menisci, fat pads, accessory ligaments, bursae. Dynamic motion: dynamic motion, linear motion, angular motion, rotation, joints classified based on type of motion permitted, monaxial, biaxial, triaxial. Types of movement: gliding motion, two surfaces slide past one another, angular motion, flexion, extension, hyperextension, abduction, adduction, circumduction. Rotational movement: left or right, medial (internal) or lateral (external, pronation or supination in the bones of the forearm only. Special movement: movements of the foot, inversion and eversion, plantar flexion and dorsiflexion, movements of the thumb, opposition.
