Structurally, joints are classified as: fibrous joint, cartilaginous joint and synovial joint. Match their definitions below. LO1

- Fibrous Joint: Connected by fibrous connective tissue - Cartilaginous joint: Connected by cartilage - Synovial joint: Connected by both

Match the image on LEFT column to its corresponding special movements.

- Image 1: Depression/elevation (Elevation - superior movement of body part Depression - inferior movement of body part) - Image 2: Plantar flexion/ Dorsiflexion (Dorsiflexion - bending of foot at ankle in direction of dorsum Plantarflexion - bending of foot at ankle joint in direction of plantar) - Image 3: Inversion/eversion (Inversion - movement of sole medially at intertarsal joints Eversion - movement of sole laterally)

Symphysis structure and function. LO 2, 3, 4

Cartilaginous joint; amphiarthrosis

Synchondrosis structure and function. LO 2, 3, 4

Cartilaginous joint; amphiarthrosis/synarthosis

Suture structure and function. LO 2, 3, 4

Fibrous joint; synarthrosis

Match the image on LEFT column to its corresponding angular movement. LO5

- Image 1: Abduction/adduction (Abduction - movement of bone away from midline. Adduction - movement of bone toward midline) - Image 2: Circumduction (Movement of distal end of body part in a circle. Not a movement but a continuous sequence of flexion, abduction, extension, adduction and rotation of joint) - Image 3: Flexion/extension (Flexion - decreases the angle Extension - increases the angle) - Image 4: Hyperextension/flexion/extension (Hyperextension - movement where extension is performed at any joint beyond its normal range of motion)

Match the image on LEFT column to its corresponding rotational movements. LO5

- Image 1: Lateral/medial roation (Lateral rotation - anterior surface limb bone turns away from midline Medial rotation - anterior surface limb bone turns toward the midline) - Image 2: Right/left rotation - Image 3: Pronation/supination (Supination - movement of forearm at proximal and distal radioulnar joints in which palm is turned anteriorly. Pronation - movement of forearm at proximal and distal radioulnar joints in which distal end of radius crosses over distal end of ulna and palm is turned posteriorly)

Match the image on LEFT column to its corresponding special movements. LO5

- Image 4: Retraction/protraction (Protraction -movement of a part of the body anteriorly in the transverse plane Retraction - movement of a protracted part of the body back to the anatomical position) - Image 5: Opposition (movement of thumb in which thumb moves across palm to touch tips of fingers on same hand) - Image 6: Lateral flexion (Lateral flexion - movement of body part to the side)

Special categories are given to diarthroses (synovial joints), based on motion. Define the words below briefly. LO6

- Monaxial: Also known as uniaxial. Allow motion around a single axis. - Biaxial: Permit movement in two axes. - Triaxial: Also known as multiaxial. Permits movement in three axis.

Although all synovial joints share many characteristics in common, the shapes of the articulating surfaces vary; thus, many types of movements are possible. In most joint movements, one bone remains in a fixed position while the other moves around an axis. Synovial joints are divided into six special classification based on type of movement: plane, hinge, pivot, condyloid, saddle, and ball-and-socket. Assign one of the three types of motion for each special classification. LO6

- Plane joint: Biaxial and triaxial - Pivot and hinge joints: Monaxial/uniaxial - Saddle and condyloid joints: Biaxial - Ball-and-socket joint: triaxial

Intervertebral joints. LO7, LO8

Functionally, joints are classified as: synarthrosis, amphiarthrosis and diarthrosis. Match their definitions below. LO1

- Synarthrosis: Immovable - Amphiarthrosis: Somewhat movable - Diarthrosis: Freely movable
