Clavicle
This is the first bone in the body to ossify (5th–7th week in utero).
What is the clavicle?
This cavity determines the lateral side of the scapula.
What is the glenoid cavity?
The head of the humerus faces this direction.
What is medially and backward?
This groove separates the greater and lesser tubercles.
What is the intertubercular sulcus (bicipital groove)?
This rounded projection is located laterally.
What is the capitulum?
This part of the clavicle is large and quadrilateral.
What is the medial (sternal) end?
The scapula has this many borders, angles, and surfaces.
What are 3 borders, 3 angles, and 2 surfaces?
This epicondyle is more prominent.
What is the medial epicondyle?
This neck separates the head from the rest of the upper end.
What is the anatomical neck?
This pulley-shaped projection is located medially.
What is the trochlea?
The clavicle is commonly fractured at this junction.
What is the junction between the medial 2/3 and lateral 1/3?
This process extends laterally from the spine of the scapula.
What is the acromion process?
This fossa faces posteriorly.
What is the olecranon fossa?
This tubercle is located on the anterior aspect.
What is the lesser tubercle?
This fossa lies above the trochlea anteriorly.
What is the coronoid fossa?
The inferior surface of the clavicle is characterized by this feature.
What is a longitudinal groove in the middle one-third?
This tubercle is located above the glenoid cavity.
What is the supraglenoid tubercle?
The longest bone of the upper limb is this bone.
What is the humerus?
This tubercle is located laterally on the upper end.
What is the greater tubercle?
Common fracture sites include the surgical neck, shaft, and this region.
What is the supracondylar region?
The clavicle transmits weight from the upper limb to this structure.
What is the axial skeleton?
This notch is located on the superior border of the scapula.
What is the suprascapular notch?
The shaft is rounded in the upper half and this shape in the lower half.
What is triangular?
The head of the humerus is directed medially, backward, and this direction.
What is upward?
Poor blood supply occurs at the junction of these two parts of the shaft.
What is the junction of the upper and middle one-third?
