articulations Flashcards
what bones and things articulate at the temporomandibular joint?
what kind of joint is this?
what actions does the TMJ allow?
the mandible and the temporal bone
synovial (filled with fluid from a synovial membrane) with an articulating disc.
the actions that the TMJ allows are: 1-hinge action to open the mouth, 2-gliding action for protrusion and retraction, 3-gliding from side-to-side movement of the lower jaw.
what bones and things articulate at the glenohumeral joint?
what kind of joint is this?
what actions does the joint allow?
the humerus and the glenoid fossa
ball and socket joint
this joint allows for the articulation of the shoulder girdle, adduction and abduction, circumduction, etc.
what bones and things articulate at the shoulder?
what kind of joint is this?
what actions does this joint allow?
the (proximal) humerus, the scapula
the shoulder is a ball and socket joint
adduction, abduction, flexion, extension, internal rotation, external rotation, and 360° circumduction
what bones and things articulate at the elbow?
what kind of joint is this?
what actions does this joint allow?
the humerus, radius, and ulna of the forearm
hinge joint with a brusa
The strong muscles that extend across the elbow joint bring about actions like flexion, extension, supination and pronation.
what bones and things articulate at the radiocarpal joint?
what kind of joint is this?
what movement does this joint allow?
the radiocarpal joint is the articulation of the distal radius of the arm with a row of 8 carpal bones (Some Lovers Try Positions That They Cannot Handle)
it is a condyloid synovial joint
actions like flexion, extension, and side to side deviation.
what bones and things articulate at the midcarpal joint?
what kind of joint is this?
what actions does it allow for?
the two parallel rows of carpal bones articulate at the midcarpal joint.
functional compound synovial joint
flexion, extension, internal rotation
what bones and things articulate at the metacarpophalangeal and interphalangeal joints?
what kind of joints are these?
what actions does it allow for?
the metacarpals and phalanges of the finger
MCP: condyloid type synovial joints
IP: hinge-type synovial
flexion, extension, and some rotation
what bones and things articulate at the hip joint?
what kind of joint is it?
what actions does it allow for?
the acetabulum and the head of the femur
ball and socket joint
it allows for a wide ROM, and also provides stability to the body due to muscles that spread over the joint.
what bones and things articulate at the knee
what kind of joint is this
what actions does it allow for
the femur, the tibia, and the patella
hinge joint
flexion and extension of the lower leg on a single plane.
what bones and things articulate at the ankle
what kind of joint is this
what actions does this joint allow for?
tibia, fibula, talus
hinge joint
flexion (dorsiflexion), extension (plantar flexion)
