UE Ligaments
Ulnar collateral ligament
Origin of the brachialis
Anterior mid shaft of the humerus
This network of nerves faithfully serves the antecubital and posterior uniaxial synovial joints of the upper extremities.
Brachial plexus
This triangular fibrocartilage dissipates forces at the wrist
Triangular fibrocartilaginous complex
Primary wrist extension occurs at this articulation
Radiocarpal joint
The ligament that fails in Nursemaid's elbow
Annual ligament
Glenohumeral action of the posterior deltoid
Horizontal Abduction
Lateral rotation
Extension
The group of muscles known as the rotator cuff share these common segmental nerve origins
C5 & C6
These two fibrocartilaginous disks ensure complete elevation of the shoulder complex.
Sternoclavicular articular disks
Its hard to take a "hand out" without proper supination occuring at these joints.
Radioulnar
Connects the sternal ends of the clavicles
Interclavicular ligament
Action of the supinator muscle is isolated by this position of the elbow
Extension
This nerve and its segmental nerve origins serve the extensor carpi radialis longus
Radial nerve C6,C7
This ring of wedge shaped fibrocartilage enhances the congruency and reigns in the free moving, 6 degrees of freedom loving, ball and socket joints of the upper extremity
Glenoid labrum
If the scapula doesn't upwardly rotation this shoulder joint cannot reach maximal flexion.
Glenohumeral
Posterior band of the coracoclavicular ligament
Conoid ligament
The proximal attachments of this muscle include:
Proximal clavicle
Sternum
Costal cartilage of ribs 1-6
Pectoralis major
Ulnar nerve C8 & T1
This apron of dorsal tissue has got your back!
Thoracodorsal fascia.
Maximal scaption requires full elevation and rotation of these joints respectively
sternoclavicular and acromioclavicular.
These structures combine to form the roof of the carpal tunnel.
Flexor retinaculum and the palmar carpal ligament.
This muscle has the single largest posterior proximal attachment and traverses over 8 different bony landmarks to arrive at the floor of the proximal humeral half pipe in order to produce extension, adduction and internal rotation. It is said that she is also committed to two different military men.
Latissiumus dorsi
The lumbricals are a confusing group of muscles that neither originate or insert on bony landmarks and they are served by these 2 peripheral nerves who share common segmental origins.
Ulnar and median nerves C8 & T1
This sheet of dense connective tissue allows your fingers to pinch together
palmar aponeurosis
This little joint is the only bony connection of the entire upper extremity to the thorax
Sternoclavicular joint
