To what does the sternal end of the clavicle articulate?

The sternal end of the clavicle articulates with the manubrium of the sternum to form the sternoclavicular joint.

To what does the manubrium of the sternum articulate?

The manubrium of the sternum articulates with the sternal end of the clavicle to form the sternoclavicular joint.

What joint does the sternal end of the clavicle and the manubrium of the sternum form?

Sternoclavicular joint

To what does acromial end of the clavicle articulate?

The acromial end of the clavicle articulates with the acromian process of the scapula to form the acromioclavicular joint.

To what does the acromian process of the scapula articulate?

The acromian process of the scapula articulates with the acromian end of the clavicle to form the acromioclavicular joint.

What joint does the acromial end of the clavicle and the acromian process of the scapula form?

Acromioclavicular joint

To what does the head of the humerus articulate?

The head of the humerus articulates with the glenoid fossa of the scapula to form the glenohumeral joint.

To what does the glenoid fossa of the scapula articulate?

The glenoid fossa of the scapula articulates with the head of the humerus to form the glenohumeral joint.

What joint does the head of the humerus and the glenoid fossa of the scapula form?

Glenohumeral joint

To what does the trochlea of the humerus articulate?

The trochlea of the humerus articdulates with the trochlear noth of the ulna.

To what does the trochlear notch of the ulna articulate?

The trochlear notch of the ulna articulates with the trochlea of the humerus.

To what does the capitulum of the humerus articulate?

The capitulum of the humerus articulates with the head of the radius.

To what does the head of the radius articulate?

The head of the radius articulates with the capitulum of the humerus AND the radial notch of the ulna.

To what does the radial notch of the ulna articulate?

The radial notch of the ulna articulates with the head of the radius.

To what does the olecranon process of the ulna articulate?

The olecranon process of the ulna articulates with the olecranon fossa of the humerus.

To what does the olecranon fossa of the humerus articulate?

The olecranon fossa of the humerus articulates with the olecranon process of the ulna.

How do you side a scapula?

To side a scapula, first locate the spine of the scapula (located on the posterior surface of the scapula).

Next, locate the glenoid fossa (cavity) of the scapula. Since the glenoid fossa (cavity) articulates with the head of the humerus, it has to be located on the lateral surface of the scapula.

So, to side a scapula...make sure the spine of the scapula is facing posteriorly and the glenoid fossa (cavity) is facing laterally.

How do you side a clavicle?

To side a clavicle, first locate the acromial end of the clavicle. Since the acromial end of the clavicle articulates with the acromian process of the scapula, it has to be located on the lateral end of the clavicle.

Next, locate the sternal end of the clavicle. Since the sternal end of the clavicle articulates with the manubrium of the sternum, it has to be located on the medial end of the clavicle.

Helpful Hint: Unlike the superior surface, the inferior surface of the acromial end of the clavicle is rather "bumpy".

How do you side a humerus?

To side a humerus, first locate the head of the humerus. Since the head of the humerus articulates with the glenoid fossa (cavity) of the scapula, it has to be located on the medial side of the humerus.

Next, locate the olecranon fossa of the humerus. The olecranon fossa of the humerus is located on the posterior surface of the humerus.

So, to side a humerus...make sure the head of the humerus is facing medially and the olecranon fossa of the humerus is facing posteriorly.

How do you side an ulna?

To side an ulna, first locate the radial notch of the ulna. Since the radial notch of the ulna articulates with the head of the radius, it has to be located on the lateral side of the ulna.

Next, locate the trochlear notch of the ulna. The trochlear notch of the ulna is located on the anterior surface of the ulna.

So, to side an ulna...make sure the radial notch of the ulna is facing laterally and the trochlear notch of the ulna is facing anteriorly.

How do you side a radius?

To side a radius, first locate the radial tuberosity of the radius. The radial tuberosity of the radius is located on the anterior surface of the radius.

Next, locate the styloid process of the radius. The styloid process of the radius is located on the lateral surface of the distal radius.

So, to side a radius...make sure the radial tuberosity of the radius is facing anteriorly and the styloid process of the radius is facing laterally.
