lesson 1- appendicular skeleton Flashcards
clavicle
connects scapula to sternum, slender and curved
sternal (medial) end of clavicle
medial part that articulates with the sternum
acromial (lateral) end of clavicle
lateral part of clavicle that articulates with the acromion of the scapula
conoid tubercle
prominence on the lateral end and inferior part of the clavicle
glenoid cavity (fossa)
lateral aspect of the scapula that articulates with the head of the humerous
scapula
triangle shaped shoulder blade
spine of scapula
posterior ridge of scapula
acromion (process)
scapular process extending laterally from spine of scapula, articulates with acromial end of clavicle
supraglenoid tubercle
prominence superior to the glenoid cavity
infra glenoid tubercle
prominence inferior to the glenoid cavity
supraspinous fossa
depression on the posterior surface of the scapula, superior to the spine
infraspinous fossa
depression on the posterior surface of the scapula, inferior to the spine
subscapular fossa
depression on the anterior surface of the scapula
superior border
superior ridge running from the superior angle to the glenoid cavity
lateral (axillary) border
lateral ridge running from the inferior angle to the glenoid cavity
medial (vertebral) border
medial ridge running from the inferior angle to the superior angle
superior angle
angle between the medial and superior border (scapula)
inferior angle
angle between the medial and lateral border (scapula)
head of humerus
proximal rounded portion that articulates with the glenoid cavity
anatomical neck of humerus
tapered region between the head and tubercles
humerus
long bone of arm
surgical neck
tapered region of the humeral shaft inferior to the anatomical neck
greater tubercle
bump lateral to the humeral head
lesser tubercle
bump anterior and medial to the greater tubercle
intertubercular groove
groove between the greater and lesser tubercles (humerus)
deltoid tuberosity
elevation on the lateral side of the tubercle shaft
capitulum
lateral condyle on the distal end of the humerus that articulates with the head of the radius
lateral epicondyle
projection on the distal end of the humerus superior and lateral to the capitulum
trocheala
medial condyle on the distal end of the humerus that articulates with the trochealar notch of the ulna
medial epicondyle
projection on the distal end of the humorous superior and medial to the trochlea
coronoid fossa
depression for the coronoid process on the anterior side of the distal end of the humerus
olecranon fossa
depression for the olecranon process on the posterior side of the distal end of the humerus
ulna
medial bone of forearm
trochlear notch
half-moon shaped notch that articulates with the trochlea of the humerus
coronoid process of ulna
prominence on the proximal end of the ulna smaller than and distal to the olecranon process
olecranon process
prominence on the proximal end of the ulna, larger than and proximal to the coronoid process
interosseos crest
ridge along the lateral side of the ulnar shaft
head of ulna
round bump at the distal end of the ulna
radius
lateral bone of the forearm
head of radius
knob on the proximal end of the radius
radial tuberosity
roughened elevation of the shaft
interosseos crest of radius
ridge along the medial side of the shaft
styloid shaft
pointed process at the lateral side and distal end of the radius
carpals
eight wristbones arranged in two rows (proximal and distal) of four bones each
scaphoid
most lateral carpal bone of the proximal row
triquetrum
carpal bone of the proximal row
