Bones & Landmarks of the Upper Limb, Clavicle & Scapula Flashcards
The junction between the arm and the trunk made up of the scapula and the clavicle. Other names include the pectoral girdle or the thoracic girdle.
Shoulder
A region of the upper limb made up of the humerus.
Arm
A region of the upper limb made up of the ulna and the radius.
Forearm
A region of the upper limb made up of the carpal bones.
Wrist
A region of the upper limb made up of the metacarpal bones.
Hand
A region of the upper limb made up of the phalange bones.
Fingers
Includes the skull, vertebral column, sternum and ribs.
Axial Skeleton
Includes the shoulders, upper limbs, hips and lower limbs.
Appendicular Skeleton
The first bone in the body to ossify that is S-shaped. The lateral 1/3 is flattened and this is the most common location for fracture. It connects the upper limb to the axial skeleton.
Clavicle
The _______ clavicle is concave anteriorly and the ______ clavicle is convex anteriorly.
Lateral
Medial
What are the 2 ends of the clavicle?
1) Acromial End
2) Sternal End
The end of the clavicle that connects to the scapula.
Acromial End
The end of the clavicle that connects to the manubrium.
Sternal End
A relatively flat, triangular bone that connects the clavicle to the humerus.
Scapula
The scapula sits flat against the rib cage from approximately the ___ to ___ ribs (when standing in anatomical position with proper posture).
2nd-7th
The anterior projection from the lateral end of the spine of the scapula. It is the tip of the shoulder.
Acromion
The thick, curved, anterior projection that extends from the head and neck of the scapula. It is shaped like a raven’s beak.
Coracoid Process
Where the head of the humerus articulates with the scapula and dislocations are common due to this shallow socket only making contact with 1/3 of the head of the humerus.
Glenoid Fossa (aka. Glenoid Cavity)
A small, rough prominence found along the superior portion of the head of the scapula. It is located superior to the glenoid fossa.
Supraglenoid Tubercle
The rough prominence found along the inferior portion of the head of the scapula. It is located inferior to the glenoid fossa.
Infraglenoid Tubercle
The thick, laterally located edge of the scapula extending from the lateral angle to its inferior angle.
Lateral Border (aka. Axillary Border)
The blunt area of the scapula where its medial and lateral borders meet.
Inferior Angle
The concave area that occupies almost the entire costal surface of the scapula.
Subscapular Fossa
The thin, medially located edge of the scapula extending from the superior angle to its inferior angle.
Medial Border (aka. Vertebral Border)
The sharp area of the scapula where its medial and superior borders meet.
Superior Angle
The indentation found along the lateral area of the superior edge of the superior edge of the scapula.
Suprascapular Notch
The triangular, shelf-like plate that projects from the superior area of the dorsal surface of the scapula.
Spine of the Scapula
The upper, deeply concave area on the dorsal surface of the scapula that is located superior to the spine of the scapula.
Supraspinous Fossa
The lower, slightly concave area on the dorsal surface of the scapula that is located inferior to the spine of the scapula.
Infraspinous Fossa
The medial end of the spine of the scapula.
Root of the Spine
