Intertubercular sulcus
What is the area just inferior to head of humerus called? (Anterior view)
Surgical neck
What is the small protruding bump on the lateral portion of the shaft of humerus called?
Deltoid tuberosity
What is the deep socket on distal end of humerus? (Anterior view)
Coronoid fossa
What are the two articulating surfaces of the distal end of the humerus? (Anterior view)
Capitulum and trochlea
Which is medial- Trochlea or capitulum?
Trochlea
What are the bumpy superior surfaces of the distal end of humerus called?
Medial and lateral epicondyle
Greater tubercle of humerus is seen both posterior and anterior view. True or false?
True
What is the deep socket at distal end of humerus called? (Posterior view)
Olecranon fossa
Which articulating surface of distal humerus is the only one that can be seen in posterior view?
Trochlea
What does head of humerus do?
Articulates with glenoid cavity of scapula
What is the relevance of surgical neck?
Axillary nerve course around
Also, area more likely to fracture than anatomical neck.
Relevance of greater tubercle?
Distal attachment for 3 of 4 rotator cuff muscles
Relevance of l esser tubercle?.
Distal attachment of 1 of 4 rotator cuff muscles
Relevance of Intertubercular sulcus?
Passageway for a tendon; biceps brachii long head muscle
Relevance of capitulum?
Articulates with the head of the radius
Trochlea relevance?
Articulates with trochlear notch of ulna
Structural pivot point (fulcrum) for elbow
Relevance of lateral and medial Epicondyles?
Several as proximal attachments for group muscles located in forearm
Which, of ulna and radius, has a head that is attached to humerus?
Radius
Which, of ulna and radius, has a head that is more distally located than the other?
Ulna
What is the large groove at proximal end of ulna?
Trochlear notch
What is the superior projection relative to trochlear notch?
Olecranon process
What is the inferior projection relative to trochlear notch?
Coronoid process
What is the bump near proximal end of radius?
Radial tuberosity
Where is the neck of the radius located?
Between the head and radial tuberosity
What are the two tooth like projections from the distal ends of ulna and radius?
Styloid processes
What is the tooth like projection coming from distal end of ulna called?
Ulnar styloid process
What is the tooth like projection coming from distal end of radius called?
Radial styloid process
Relevance of radius?
Articulates with capitulum of humerus
Relevance of radial tuberosity?
Distal attachment of biceps brachii
Relevance of radial styloid process?
Distal attachment: brachioradialis
Relevance of olecranon process?
Distal attachment: triceps brachii
Relevance of coronoid process?
Distal attachment: brachialis
Relevance of trochlear notch?
It (with ligaments) limits action at elbow to flexion and extension
