appendicular skeleton
the appendicular skeleton has ___ bones. What does it include?
126 upper limbs lower limbs bones or girdles that attach limbs to the axial skeleton pectoral girdle pelvic girdle.
a prominent ridge for muscle attachment
crest
a smooth, rounded articular process used for articulation
condyle
the state of being jointed.
articulation
projection above a condyle for muscle attachment
epicondyle
opening or hole for blood vessels and nerves
foramen
shallow depression for muscle attachment or articulation
fossa
rounded articular projection supported on the neck of a bone for articulation
head
an indentation or depression or groove for blood vessels and nerves
notch
a very large projection for muscle attachment
trochanter
a sharp, slender projection for muscle attachment
spine
a large, roughened projection for muscle attachment
tuberosity
attaches an upper limb to the axial skeleton
pectoral girdle
what composes the pectoral girdle
scapula and clavicle
the lateral end of the clavicle articulates with the _____ of the ______.
acromion of the scapula
the medial end of the clavicle articulates with the ______ of the ______ attaching the pectoral girdle to the axial skeleton.
manubrium of the sternum
the _____ does not articulate directly with the axial skeleton but is attached to it with muscles.
scapula
the collar bone
clavicle
shoulder blade
scapula
sharp ridge located on posterior side of scapula
spine
flattened process at lateral end of spine that articulates with the clavicle
acromion
joint socket or fossa – depression inferior to acromion that articulates with the head of the humerus
glenoid cavity
superior and medial to glenoid cavity; site for muscle attachment (crow’s beak)
coracoid process
what are the bones that the upper limbs consist of?
humerus,ulna, radius, carpals, metacarpals, phalanges
the arm bone
humerus
rounded proximal end of humerus
head
raised area between the proximal and distal ends of the humerus
deltoid tuberosity
spool shaped medial condyle on the anterior, distal end of humerus
trochlea
rounded, knob-like condyle lateral to the trochlea of humerus
capitulum
shallow anterior depression on distal end of humerus
coronoid fossa
tip of the elbow - largest depression on posterior, distal end of humerus
olecranon fossa
medial bone of forearm
ulna
large curved lip-like projection on posterior side of proximal end of ulna
olecranon
smaller, curved lip-like projection on anterior side of proximal end; distal to olecranon (of ulna)
coronoid process
deep, curved area between olecranon and coronoid process of ulna
trochlear notch
pole-like, slender, pointed projection on distal end of ulna
styloid process
lateral bone of forearm
radius
flat, disc shaped proximal end of radius
head
slender, pointed projection; distal end of radius
styloid process
the shoulder joint that connects the upper limb to the pectoral girdle is formed by the what

head of the radius with the capitulum of the humerus at the elbow joint and with the radial notch of the ulna at the Proximal radioulnar joint.
