Elbow Flashcards
proximal end of radius: head
articulates with capitulum and radial notch of ulna (proximal end)
proximal end of radius: radial tuberosity
attachment of biceps brachii
proximal end of ulna: trochlea notch
articulates with trochlea condyle of humerus,
- olecranon + coranoid process = trochlea notch
elbow joint: classification
synovial hinge, monoaxial
elbow joint: movement
flexion, extension of forearm
radioulnar joint: classification
synovial pivot, rotation monoaxial
radioulnar joint: movement
pronation, supination
- radius rotates around ulna
elbow joint: articulating surfaces
- trochlea of humerus w/ trochlear notch of ulna
- capitulum of humerus with head of radius
elbow joint: ligaments
- radial (lateral) collateral
- ulnar (medial) collateral
elbow joint: blood supply
anastomotic network: collater and recurrent branches of
- brachial
- profunda brachii
- radial
- ulnar arteries
elbow joint: innervation
- mainly radial, musculocutaneous
- ulnar
- median nerves
= elbow joint?
trochlear notch + trochlea, capitulum + head of radius
fat pads location in elbow joint:
radial, coronoid, olecranon fossae
ligament around radius and function:
- allows head of radius slide against radial notch,
- pivot on capitulum for pro/supination
radial collateral lig: attachments
lateral epicondyle - annular lig.
