Flashcards in October 27, 2015 - Upper Limb I Deck (20):
1

Scapula

The bone in your shoulder. It has several parts to it.

The acromion process is posterior

Coracoid process is anterior

Glenoid cavity connects to the humerus

Scapular spine is the ridge along the back.

Clavicle

The only bony attachment for the upper limbs. Attached via the acromioclavicular joint to the acromion process of the scapula, and also attached to the sternoclavicular joint on the sternum.

Glenohumeral Joint

Where the humerus and the scapula meet. 

The head of the humerus interacts with the glenoid cavity on the scapula to form the glenohumeral joint. There is articular cartilage and synovial fluid inside the joint.

4

Acromioclavicular Joint

Also known as the AC joint.

Connects the acromion with the clavicle.

5

Coracoacromial Ligament

Connects the acromion to the coronoid process. Provides an upper slung to prevent the shoulder from moving too far.

Coracoclavicular Ligament

Connects the coracoid process to the clavicle.

Condyles

Are sites of muscular attachment.

For example, the lateral epicondyle of the humerus.

8

Capitulum (humerus)

The round protuberence on the distal part of the humerus.

It consists of a smooth, rounded eminence which articulates with the cup-shaped depression on the head of the radius.

9

Trochlea (humerus)

The medial portion of the articular surface of the elbow joint, which articules with the trochlear notch on the ulna in the forearm.

Interosseous Membrane

The membrane between the radius and ulna (as well as between the tibia and fibula).

This allows movement, but also allows them to stay together.

Scaphoid

Big carpal in the hand that is at the base of the wrist and the thumb.

Lunate

A carpal at the base of the wrist furthest from the thumb (near the ulna)

Joints in the Hand

Interphalangeal joints (between phalanges)

Carpometacarpal joint (between metacarpals and carpals)

Intercarpal joint (between carpals)

Radiocarpal joint (between carpals and the radius)

14

Arterial Circulation

Begins with the subclavian artery, which becomes the axillary artery, which becomes the brachial artery, which then branches into both the radial artery and the ulnar artery.

Blood Supply to Shoulder

The subclavian artery has several branches to feed the shoulder. The transverse cervical artery goes down the side of the scapula. The suprascapular artery goes over the top of the artery. The subscapular artery branches off below the scapula.

Arteries of the Forearm and Hand

The radial artery and the ulnar artery anastimose in the hand.

The radial artery takes a dive under the thumb, while the ulnar artery comes up near the pinky before diving.

17

Scapulothoracic Joint

An articulation of the scapula with the thorax.

Winged Scapula

Caused by a non-functioning (torn or paralyzed) serratus anterior. When the patient pushes against a wall, the scapula will push out the back.
