Questions 2026
Clavicle - ANSWER ✨✔---Short and round. "collar bone"
Sternal End - ANSWER ✨✔---part of the clavicle that forms a saddle joint with clavicle and sternum
Sternoclavicular Joint - ANSWER ✨✔---Saddle joint or clavicle and sternum. Joins axial skeleton
with upper limb. Allows moderate freedom of movement in two planes.
Acromial End - ANSWER ✨✔---part of the clavicle that is flattened and forms a fixed
acromioclavicular joint with the acromion.
Scapula - ANSWER ✨✔---Flat and triangular that glides over the posterior surface of the thorax.
,Coracoid Process - ANSWER ✨✔---Attachment on the scapula for the biceps brachii
Acromion - ANSWER ✨✔---joins the scapula to the clavicle
Spine of Scapula - ANSWER ✨✔---forms a ridge that separates the posterior surface of the scapula
into 2 fossae.
Supraspinous Fossa - ANSWER ✨✔---Superior to the spine of scapula. Houses the rotator cuff with
other scapula fossae.
Infraspinous Fossa - ANSWER ✨✔---Inferior to the spine of scapula. Houses the rotator cuff with
other scapula fossae.
Subscapular Fossa - ANSWER ✨✔---The anterior surface of the scapula. Houses the rotator cuff
with other scapula fossae.
Head of Humerus - ANSWER ✨✔---end of humerus that articulates with the glenoid cavity of the
scapula.
Glenoid Cavity - ANSWER ✨✔---where the head of the humerus articulates with the scapula. A
shallow socket that is reinforced by cartilage and ligaments.
Supraglenoid Tubercle - ANSWER ✨✔---Bump above the glenoid cavity. Attachment for parts of
biceps.
Infraglenoid Tubercle - ANSWER ✨✔---Bump below the glenoid cavity. Attachment for parts of
triceps.
Humerus - ANSWER ✨✔---only bone of the brachium.
Greater Tubercle - ANSWER ✨✔---On lateral side of humerus near the head.
, Lesser Tubercle - ANSWER ✨✔---On medial side of humerus near the head.
Glenohumeral Joint - ANSWER ✨✔---a ball and socket joint that connects the humerus to the
scapula. Allows for freedom of movement. Reinforced by cartilage and ligaments. Prone to dislocation.
Intertubercular Groove - ANSWER ✨✔---Between the greater and lesser tubercles. Attachment
site for some muscles that move the humerus.
Anatomical Neck - ANSWER ✨✔---narrowing behind the head of the humerus. Proximal
Surgical Neck - ANSWER ✨✔---more distal neck of the humerus. Prone to fractures
Deltoid Tuberosity - ANSWER ✨✔---On mid-shaft of the humerus on the anterior surface.
Attachment for deltoid muscle.
Trochlea - ANSWER ✨✔---The articular surface of the humerus for the ulna. Spool-shaped,
meanswer "pulley"
Capitulum - ANSWER ✨✔---The articular round surface on the humerus for the radius. Meanswer
"head"
Radial Fossa - ANSWER ✨✔---Anterior side of humerus, superior to capitulum (for radius)
Cornoid Fossa - ANSWER ✨✔---Anterior side of humerus, superior to trochlea (for ulna)
Olecranon Fossa - ANSWER ✨✔---Posterior side of humerus, meaning "cannon"
Medial Epicondyle - ANSWER ✨✔---prominent ridge beside the trochlea and capitulum.
Attachment for most of the muscles of the anterior forearm.
