5) Sensory/nerve
Both the upper and lower limbs are connected to the {…} skeleton (cranium, vertebral column, and associated thoracic cage) via the bony {…} and {…} girdles, respectively.
1) Axial
2) Pectoral
3) Pelvic
The {…} girdle consists of the two hip bones connected to the sacrum.
Pelvic
The {…} girdle consists of the {…} and {…} connected to the {…} of the sternum.
1) Pectoral
2) Scapulae
3) Clavicles
4) Manubrium
The pectoral girdle and bones of the free part of the upper limb form the {…} appendicular skeleton; the pelvic girdle and bones of the free part of the lower limb form the {…} appendicular skeleton.
1) Superior
2) Inferior
The superior appendicular skeleton articulates with the axial skeleton only at the {…} (SC) joint, allowing for great {…}.
1) Sternoclavicular
2) Mobility
The clavicles and scapulae of the pectoral girdle are supported, stabilized, and moved by {…} muscles that attach to the relatively fixed ribs, sternum, and vertebrae of the {…} skeleton.
1) Axio-appendicular
2) Axial
The {…} (collar bone) connects the upper limb to the {…} (body).
1) Clavicle
2) Trunk
The {…} of the clavicle has a double curve in a {…} plane. Its medial 2/3 is {…} (shaped) anteriorly, and its {…} end is enlarged and triangular where it articulates with the {…} of the sternum at the {…} (SC) joint.

The {…} surface of the clavicle is rough because strong {…} bind it to the {…} (number) rib near its {…} end and suspend the scapula from its {…} end.
1) Inferior
2) Ligaments
3) 1st
4) Sternal
5) Acromial
The conoid {…} (i.e., knob-like bony landmark), near the {…} end of the clavicle, gives attachment to the conoid {…}, the medial part of the {…} ligament by which the remainder of the upper limb is passively suspended from the clavicle.
1) Tubercle
2) Acromial
3) Ligament
4) Coracoclavicular
Also, near the acromial end of the clavicle is the {…} line, to which the {…}{…} attaches; while the conoid ligament is the medial part of the coracoclavicular ligament, the trapezoid line is the {…} part.
1) Trapezoid
2) Trapezoid
3) Ligament
4) Lateral
The {…} groove in the {…} (proximal, medial, or distal?) 1/3 of the shaft of the clavicle is the site of attachment for the {…} muscle.
1) Subclavian
2) Medial
3) Subclavius
This clavicular structure is a rough, often depressed, oval area that gives attachment to the ligament binding the 1st rib to the clavicle, limiting elevation of the shoulder; it is more medial than the subclavian groove.
What is the impression for the costoclavicular ligament?
The {…} (shoulder blade) is a triangular flat bone that lies on the {…} (intermediate direction) aspect of the thorax, overlying ribs {…} through {…}.

Superolaterally, the lateral surface of the scapula has a {…} cavity, which receives and articulates with the {…} of the humerus at the glenohumeral joint.
1) Glenoid
2) Head
The glenoid cavity is a shallow, concave, oval {…}, directed {…} (intermediate direction) and slightly {…} (direction) on the scapula and is considerably smaller than the ball (i.e., head of the humerus) for which it serves as a {…}.

2) Superior
3) Anterolaterally
When the scapular body is in the anatomical position, the thin {…} border of the scapula runs parallel to and approximately 5 cm lateral to the {…} processes of the thoracic vertebrae; hence, it is often called the {…} border.
1) Medial
2) Spinous
3) Vertebral
From the inferior angle, the {…} border of the scapula runs {…} (intermediate direction) toward the {…} of the axilla (i.e., the cervico-axillary canal); hence, it is often called the {…} border.

2) Superolaterally
3) Apex
4) Axillary
The lateral border terminates in the truncated {…} angle of the scapula, the thickest part of the bone that bears the broadened {…} of the scapula.
1) Lateral
2) Head
The shallow constriction between the head and body defines the {…} of the scapula.
Neck
The {…} border of the scapula is marked near the junction of its medial {…} (fraction) and lateral {…} (fraction) by the {…} notch, which is located where the superior border joins the {…} of the {…} process.
1) Superior

The inferior end of the humeral shaft widens as the sharp medial and lateral {…} (supracondylar) ridges form and the end distally in the especially prominent {…} epicondyle and the {…} epicondyle, providing for muscle attachment for the anterior and posterior muscles of the forearm.
1) Supra-epicondylar
2) Medial
3) Lateral
This part of the distal humerus is comprised of the trochlea and capitulum, as well as the olecranon, coronoid, and radial fossae.
What is the condyle of the humerus?
The condyle of the humerus has two articular surfaces: a lateral {…} for articulation with the head of the radius and a medial, spool-shaped, or pulley-like {…} for articulation with the proximal end of the ulna.
1) Capitulum
2) Trochlea
This bony landmark is located on the proximal end of the ulna and allows for articulation with the arm’s trochlea.
What is the trochlear notch?
Anteriorly, the {…} fossa receives the coronoid process of the ulna during full flexion of the elbow.
Coronoid
Posteriorly, the {…} fossa accommodates the olecranon of the ulna during full extension of the elbow.

Superior to the capitulum anteriorly, a shallower {…} fossa accommodates the edge of the head of the radius when the forearm is fully flexed.
Radial
The stabilizing bone of the forearm that is the medial and longer of the two forearm bones.
What is the ulna?
What are the 2 prominent projections of the ulna?
1) Olecranon
2) Coronoid process
This ulnar projection extends proximally from its posterior aspect, forming the point of the elbow and serving as a short lever for extension of the elbow.
What is the olecranon?
This ulnar projection extends/projects anteriorly.
What is the coronoid process?
The olecranon and coronoid processes form the walls of the {…} notch, which in profile resembles the jaws of a crescent wrench as it “grips” (articulates with) the trochlea of the humerus.
Trochlear
Inferior to the coronoid process, is the {…} (osteologic landmark) of the ulna for attachment of the tendon of the {…} muscle.
