Cephalic vein
Ascends in the subcutaneous tissue from the lateral aspect of the dorsal venous network, proceeding along the lateral border of the wrist and the anteriorlateral surface of the forearm and arm
Basilic vein
Ascends in the subcutaneous tissue from the medial end of the dorsal venous network along the medial side of the forearm and inferior part of the arm
The musculocutaneous turns into
Lateral cutaneous nerve of the forearm
The radial nerves branches
In the cubital region into…
Deep branch- turns into posterior interosseous nerve
&
Superficial branch- goes snuff box
The median nerve is the …
Principal nerve of the anterior compartment of the forearm. It enters the forearm with the brachial artery and lies medial to it.
Near the wrist the median nerve becomes…
Superficial by passing between the tendons of the FDS and FCR.
Anterior interosseous nerve is a major branch of what nerve?
Median nerve
The brachial artery ends in _________ by dividing into _____
the distal part of the cubital fossa by dividing into the ulnar and radial arteries
The pulsation of the radial artery is usually measured…
On the distal radius between the tendons of flexor carpi radialis and abductor pollicis longus
Distal radio-ulnar joint is a ____
Synovial pivot joint
What is the main uniting structure of the distal radio-ulnar joint?
Fibrocartilaginous articular disc
The proximal surface of this triangular disk articulates with the distal aspect of the head of the ulna
Ligaments of the distal radio ulnar joint
Anterior and superior ligaments strengthen the fibrous layer of the joint capsule . These relatively weak transverse bands extend from the radius to the ulna across the anterior and posterior surfaces of the joint
Distal ru joint
Rounded head of ulna articulates with ulnar notch of medial side of distal radius
Druj
Disc also separates distal ru joint from wrist joint
Synovial membrane extends superiorly between the distal radius and ulna
Functions to transmit loads from hand to forearm
Contents of triceps hiatus?
Deep artery of arm
Radial nerve
Radiocarpal joint
Distal radius with the scaphoid, lunate, and tfcc
Condyloid, synovial joint
Wrist Joint capsule
Distal radius, ulna, and proximal carpals, lined with synovium
Midcarpal / intercarpal joint
Plane synovial joint between two rows of carpals
What ligaments help strengthen the wrist joint capsule
Anterior and posterior ligaments
Ulnar collateral - attaches to ulnar styloid process and triquetrum
Radial collateral -attaches to styloid process of radius and scaphoid
Ulnar deviation limited by…
Radial deviation limited by…
Ulnar> radial collateral lig
Radial> ulnar collateral lig
Colles fracture
Fracture of distal radius with dorsal displacement
Carpal tunnel syndrome
Comes with repetitive flexion
Tendons become inflamed / larger causing pressure on median nerve
Carrying angle is attributed to the way the trochlea of the ulna sits in the trochlear notch
1.
Pronation supination happens at prox and distal ru joint
Radial notch
Ulnar notch
2.
Cubital fossa for bp pressure
Borders
3
Capsule of elbow weak anterior/ posterior ( don’t matter much cuz olecranon)
4
Head of ulna articulates with unar notch on radius
5
Tfcc
Purpose to provide stability to wrist
Radial ulnar lig
Innervation*
6
Snuff box
Scaphoid floor
Superficial rad nerve an…
7
Extensor mechanism
Extensor dig, and all the others of the ext mech
At the wrist stability mostly cuz carpal bones
8
Triangular space contents
Circumflex scapular artery
Triangular space borders
Superiorly - teres min
Inferiorly- teres maj
Laterally- triceps long head
Pectoral girdle
Is a bony ring, incomplete posteriorly, formed by scapulae and clavicles and completed anteriorly by manubrium and sternum
The pectoral girdle and bones of the free part of the upper limb form the _____ ________ ______, which articulates with the axial skeleton only at the _______ joint.
Superior appendicular skeleton
Sternoclavicular
The part of the clavipectoral fascia inferior to the pectoralis minor is called ? And does what?
The suspensory ligament of axilla, supports the axillary fascia and pulls it and the inferior skin to it upward during abduction of the arm, forming the axillary fossa.
The extensor and flexor retinaculum is formed by
Thickened antebrachial fascia
The posterior shoulder muscles are divided into 3 groups
Superficial posterior axioappendicular (traps and lats)
Deep posterior axioappendicular ( levator scap and rhomboids
Scapulohumeral intrinsic shoulder muscles( the four rotator cuff muscles, teres major, and deltoid)
The roots of the brachial plexus pass between anterior and middle scalenes along with …
Subclavian artery
Each trunk of the brachial plexus divides into…as the plexus passes through the…
Into anterior and posterior divisions as th plexus passes through the cervicoaxiallary canal posterior to the clavical
The cords of the brachial plexus are named in relation to their position to the
second part of the axillary artery
The median and ulnar nerve
Supply no branches to the arm, however they supply articular branches to the elbow joint
In the subcutaneous tissue overlying the cubital fossa are…
The median cubital vein
Medial and lateral cutaneous nerves of the forearm
The median nerve lies medial to the ____ in the cubital fossa
Brachial artery
