Closer to the head

Farther from the head

Toward the front of the body

Toward the back of the body

Toward the midline of the body

Away from the midline of the body

Closer to the trunk

Away from the trunk

Toward the surface of the body

Inside the body, away from skin surface

Moving away from midline of body or body part

Moving toward the midline of body or body part

Moving to the superior position

Moving to the inferior position

Turning about the vertical axis of the bone

Rotating forearm laterally (palm faces front of body)

Rotating forearm medially (palm faces back of body)

Turning the foot in toward the center

Turning the foot out to the hip

Pointing toes

Lifting toes while keeping heel on ground

Circumscribing a conical area, involving flexion, abduction,

extension, and adduction in sequence

Joints connected by fibrous tissue with no joint cavity.

Bony surfaces are immovable or have very little

movement relative to one another. (i.e. tib-fib joint)

Joints in which cartilage (ex. fibrocartilage or sometimes hyaline)

exists at the interface but there is no joint cavity.

Bony surfaces are immovable or have some

movement relative to one another.

Allow for a large degree of relative motion

between the opposing bones and contain a joint

cavity. All are diarthrodial (freely moveable).

Freely movable joints

Synovial joins have a lone of this type of cartilage layering the ends of the involved bones.

Synovial joinds are encloused by a strong…

This membrane lines the inner surface of a synovial joint capsule

T or F: Synovial joints have nerve fibers and blood vessels for the membranes.

latin word

meaning “purse” is a

flattened fibrous sac

lined by a synovial

membrane to reduce

friction

An elongated bursa that wraps around a tendon

Synovial joints, but another name

Ball and socket (shoulder)

Condylid (wrist)

Gliding (intercarpal joints)

Hinge joint (elbow, knee)

Pivot (radius to ulna joint)

Saddle (thumb joint)

Type of Cartilage
– Distribution of loads over joint surface

– Improvement of fit of articulating surfaces (femoral

condyles and tibial plateau)

– Limitation of bone slip within joint

– Protection of periphery of articulation

– Lubrication

– Shock absorption

Type of Cartilage
Dense, white connective tissue that provides a protective

lubrication.

– 1-5 mm thick (varies depending on anatomical site)

– Coats the ends of articulating bones in diarthrodial joints

– Load support via the thickness, surface contour, and material

properties

Type of Cartilage
Larynx, epiglottis, external ear
