is the study of joints or articulations

ARTHROLOGY

based on the amount of movement allowed at the joint

is an immovable joint where the bones are rigidly joined together.

is a slightly movable joint

freely movable joint.

classification of articulation

three types of joints accodring to functional classification

4 types of synarthrosis in the book

3 classicfication of synarthrosis

two types of amphiarthroses

other name for amphiarthrosis

example of diarthrosis

if the fibrous joint united by?

if fibrous joint is in functional classification what it is

joint cavity is wanting. they are mainly immovable joint

are joints wherein the bones are united by a plate of hyaline cartilage or a fibrocartilaginous disk - they lack a joint cavity, and permit little or no movement

joints wherein the ends of the bones are covered with a smooth hyaline articular cartilage and is lubricated by a thick fluid called synovial fluid or synovia/vium -the joint is freely movable with a joint cavity.

(ball-and socket joint): the globe-like head of one bone fitted into cuplike concavity of another bone. E.g. hip joint, shoulder joint

hinge joint): a convex surface of one bone fitted into concave surface of other. E.g. knee joint, elbow joint; ankle joint.

condyloid): an oval-shaped articular surface fits into an elliptical cavity. E.g. wrist joint (between radius and carpal bones).

trochoid or rotary joint): central bony pivot surrounded by collar of bone and ligament. E.g. atlanto-axial joint, proximal radio- ulna joint.

opposing articular surfaces with both concave and convex surfaces that fit into one another. E.g. carpometacarpal joint of thumb.

essentially flat articular surfaces. E.g. some carpal bones; tarsal bones

varities of diarthroses or synovial joint

is the bending motion in which angle between two bones is decreased. E.g. bending of forearm at elbow or leg at knee.

is the straightening motion in which angle between two bones in increased (opposite of flexion). E.g. straightening of forearm at elbow or leg at knee

is movement away from the midsagittal plane of the body. E.g. raising upper extremity to side; spreading of fingers

is movement toward the midsagittal plane. Eg bringing the arm back to the side of the body; pulling the fingers back

is movement in which the distal end of the bone moves in circular potion while the proximal end remains stable; accomplished

the movement of body part (usually entire extremity) around its own axis without any displacement of its axis. Eg shaking of head in saying "no

is the pivoting movement of forearm in which the radius is rotated to become parallel to ulna (or into anatomic position). Eg movement using in tightening a screw with screwdriver, so that the palm faces forward at the end of the movement

the pivoting movement of forearm in which the radius is rotated diagonally across ulna Eg pivot of forearm that turns palm backward

protraction

is backward movement. Eg pulling of jaw backward

is the movement of sole foot inward (medially). Eg. movement of foot in which the big toe is turned upward and away from the midline of the body.

is the movement of sole of feet outward (laterally). E.g. movement of foot in which the big toe is turned downward and toward midline of body

bones in carpo-metacarpal joint

participating for wrist joint

hip joint

bones of the knee joint

elbow joint

bones of carpo metacarpal

the pivoting movement of forearm in which the radius is rotated to become parallel to ulna (or into anatomic position) Eg movement using in tightening a screw with screwdriver, so that the palm faces forward at the end of the movement.

pivoting movement of forearm in which the radius is rotated diagonally across uina. E.g. pivot of forearm that turns palm backward.

hip joint, shoulder join

knee joint, ankle joint

wrist joint (between radius and carpal bones)

atlanto axial joint and radio-ulna

carpometacarpal joint

carpal and tarsal bone
