Question
Answer
Fibrous joints   Synarthroidal joints  
Synarthrodial joints   Immoveable joints  
Cartilaginous joints   Slightly moveable joints  
Synovial joints   Freely moveable joints  
Hinge joints   Joints that act like a door on hinges, ex. knee  
Condylar joints   Joints formed by a convex surface within a concave surface permitting movement in two planes, ex. wrist  
Ellipsoidal joints   Condylar joints  
Glinding joints   Formed by two flat surfaces coming together allowing side to side, back and forth movement and rotation, ex. intercarpal joints  
Saddle joints   Formed by two saddle shaped surfaces allowing stabilized movement in two planes, ex. carpometacarpal joint in the thumb  
Ball and socket joints   Formed by a round, convex surface in a socket or cavity allowing movement in all planes, ex. shoulder  
Pivot joints   Formed by a cone shaped surface articulating with a concave notch of another bone allowing rotation only, ex. axis to atlas  
Flexion   Bending movement that reduces the angle of a joint  
Extension   Increases the angle of the joint  
Hyperextension   Increasing the angle of the joint past 180 degrees, ex. looking up at the sky  
Abduction   Moving away from the midline of the body  
Adduction   Moving towards the midline of the body  
Supination   Rolling the forearm so the palm faces anteriorly  
Pronation   Rolling the forearm so the palm faces posteriorly  
Rotation   Movement around the long axis of the bone  
Lateral rotation   Rotating the anterior segment of the bone laterally  
Medial rotation   Rotating the anterior segment of the bone medially  
Right and left rotation   Rotation of the trunk or neck to the right or left  
Circumduction   Circular or cone shaped movement involving a combination of flexion, extension, abduction, and adduction, ex. drawing a circle on a chalkboard with a straight elbow  
Elevation   Lifting a body part upwards  
Depression   Moving a body part downwards  
Dorsiflexion   Pulling the top or dorsal surface of the foot upwards  
Plantar flexion   Pointing the plantar surface of the foot downwards  
Eversion   Rolling the sole of the foot to face more laterally  
Inversion   Rolling the sole of the foot to face more medially  
Protraction   Moving a body part forward  
Retraction   Moving a body part backward  
Horiziontal abduction   Moving an abducted part of the body backward, ex. lowering the body in a push-up  
Horizontal adduction   Moving and abducted body part forward, ex. pushing the body up in a push-up  
Lateral flexion   Bending the trunk or neck laterally  
Nuchal ligament   Binds spinous processes of the cervical vertebrae together  
Acromioclavicular ligament   Binds the distal end of the clavicle with the acromion process  
Transverse carpal ligament   Covers the tendons for the wrist and finger flexors  
Flexor retinaculum   Transverse carpal ligament  
Anterior cruciate ligament   Connects the femur to the tibia  
Medial collateral ligament   Connects the tibia tot eh femur  
Anterior talofibular ligament   Binds the distal fibula with the talus  
Anterior longitudinal ligament   Covers the anterior side of the vertebrae  
Posterior longitudinal ligament   Situated within the vertebral canal, and extends along the posterior surfaces of the bodies of the vertebræ, from the body of the axis, where it is continuous with the membrana tectoria, to the sacrum  
Ligamentum flavum   Between lamina of adjacent vertebrae  
Supraspinous ligament   Between spinous processes  
Ligamentum nuchae   Nuchal ligament  
Interspinous ligaments   From one spinous processes to another  
Intertransverse ligaments   Between transverse processes  
Ipsilateral   Same side (movement)  
Ipsiflexor   Same side (movement)  
Contralateral   Affects opposite side (twist, movement)  
Contraflexor   Affects opposite side (twist, movement)  
Unilateral   One side only contracting (movement)  
Uniflexor   One side only contracting (movement)  
Bilateral   Both sides  
Radial deviation   Towards the radius (supination, abduction)  
Ulnar deviation   Towards the ulna (pronation, adduction)  
Lateral rotation of scapula   Upward  
Medial rotation of scapula   Downward  
Opposition   Bringing the thumb to touch the tips of the fingers of the same hand
