Elbow anatomy Flashcards
three bones of elbow
humerus of the upper arm,
bones of the forearm, the radius laterally and the ulna medially
three joints of the elbow
hinge joint formed between the Humerus and the Ulna (humeroulnar joint - bend and straighten our elbows
humeroradial joint between the Radius and Humerus -flexion and supination/pronation
pivot joint formed by the Radius and Ulna (proximal radioulna joint)
strongest elbow flexor
brachial (when the palm is extended/pronated)
golfers elbow aka
medial epicondylitis
muscle that is prone to golfers elbow
pronator teres
movements of pronator trees
flexion of the elbow and pronate the forearm
tennis elbow aka
Lateral Epicondylitis
muscle that is prone to tennis elbow
Extensor Carpi Radialis Brevis:
movements of Extensor Carpi Radialis Brevis:
extend the wrist and aid extension of the elbow
biceps brachia movement
flex the elbow joint and supinate the forearm.
main extensor of the elbow.
Triceps Brachii:
3 ligaments of the elbow joint
ulnar collateral,
radial collateral
annular
Ulnar Collateral Ligament is
two triangular bands, anterior and posterior
both sections of the ulnar collateral ligament arise from
Medial Epicondyle
medial collateral ligament includes
ulnar collateral ligament
anterior portion of the UCL then attaches to the front part of the top of the Ulna, known as the
Coranoid process
posterior part of ulnar collateral ligament goes to the back of the Ulna
olecranon process
Lateral Collateral Ligament include
radial collateral ligament
what does the radial collateral ligament do
strengthens the side of the wall of the joint capsule of the elbow,
radial collateral ligament description
fibrous band extending between the lateral epicondyle of the humerus (upper arm bone) and the annular ligament of the radius
annular ligament attached to margin of
trochlear notch
annular ligament encircles the _________, functioning to keep the head in contact with the _________
head of the radius
radial notch of the ulna
what is the cubital tunnel
channel which allows theUlnar nerveto travel over theelbow.
what boarders the cubital tunnel
bordered by themedial epicondyle of the humerus, theolecranonprocess of the ulna and the tendinous arch joining the humeral and ulnar heads of theflexor carpi ulnaris
main bursa of the elbow
olecranon bursa
