Appendicular Skeleton Flashcards
slender curved bone which connects the scapula to the sternum
clavicle
most medial part of the clavicle which forms a joint with the sternum, ends abruptly
sternal end
most lateral part of the clavicle which forms a joint with the scapula
acromial end
triangular shaped shoulder blade
scapula
posterior ridge of scapula
spine
scapular process extending laterally from the spine of the scapula, articulates with the clavicle
acromion process
process on the anterior, superior side of the scapula near the glenoid cavity extending laterally
coracoid process
lateral aspect of scapula which serves as point of articulation with the humerus
glenoid fossa/cavity
prominence superior to the glenoid fossa
supraglenoid tubercle
prominence inferior to the glenoid fossa
infraglenoid tubercle
depression on the anterior surface of the scapula
supscapular fossa
to ridge
superior border
junction of the superior and medial borders
superior angle
vertebral side of scapula
medial border
junction of the medial and lateral borders
inferior angle
axillary side of scapula
lateral border
long bone of the upper arm
humerus
proximal rounded portion which articulates with the glenoid cavity of scapula
head
tapering of the humerus immediately inferior to the head
anatomical neck
a process lateral to the humeral head and inferior to the anatomical neck
greater tubercle
process anterior to the greater tubercle of the humerus
lesser tubercle
groove between the greater and lesser tubercles of the humerus
intertubercular groove
tapering region of the humeral shaft inferior to the anatomical neck
surgical neck
elevation on lateral side of the humeral shaft for muscle attachment
deltoid tuberosity
lateral condyle on the distal end of the humerus which articulates with the head of the radius
capitulum
medial condyle on the distal end of the humerus which articulates with the trochlear notch
trochlea
located on the distal end of the humerus superior to the capitulum
lateral epicondyle
located on the distal end of the humerus superior to the trochela
medial epicondyle
smooth prominence located proximal to medial epicondyle for muscle attachement
medial supracondylar ridge
smooth prominece located proximal to lateral epicondyle for muscle attachment
lateral supracondylar ridge
located on the anterior side of the distal end of the humerus superior to the trochlea and articulates with the coronoid process of the ulna
coronoid fossa
located on the posterior side of the distal end of the humerus superior to the trochlea and articulates with the olecranon process of the ulna
olecranon fossa
the medial bone of the forearm
ulna
half moon shaped notch which forms a hinge joint with the trochlea of the humerus
trochlear notch
located on the proximal end of the ulna, smaller than and distal to the olecranon process
coronoid process
located on the proximal end of the ulna, larger than and proximal to the coronoid process
olecranon process
depression on the proximal end of the ulna, articulates with the head of the radius.
radial notch
short vertical ridge inferior to radial notch
supinator crest
ridge along the lateral portion of the ulnar shaft that points towards the radius
interosseous crest
distal region of the ulna
head
medial projection at the distal end
styloid process
lateral bone of the forearm
radius
knob on the proximal end of radius
head
region between head and radial tuberosity
neck
a roughened elevation on radial shaft
radial tuberosity
ridge along medial portion of the shaft that points towards the ulna
interosseous crest
depression on the medial distal end of the radius, articulates with the head of the ulna
ulnar notch
lateral projection on the distal end
styloid process
consisting of eight wrist bones arranged into two rows of four
