Let's get swole!
Name all 4 muscles of the rotator cuff
SITS: Supraspinatus, infraspinatus, teres minor, & subscapularis
The Serratus Anterior is innervated by this nerve. when injured, it leads to a winged scapula.
This bone articulates with the thumb metacarpal bone and creates a saddle joint
Trapezius
At this point, the axillary artery turn into the brachial artery
This muscle is responsible for controlling grip
Palmaris longus
These mucles flex the forearm at the elbow and two help flex the humerus at the shoulder and are innervated by the musculoscutaneous nerve.
Brachialis, biceps brachii, coracobrachialis
Where do they originate and insert?
Your palmar surface is innervated by which two nerves. One is from the thumb to the ring finger, the other is from the pinky to the ring finger.
Median and Ulnar
The deltoid and supraspiantus are the main muscles involved in which movement of what joint?
Abduction at the glenohumeral joint
When a patient has a FOOSH and they come in with lateral proximal thenar pain, we are concerned about a scaphoid fracture. The artery that provides blood to the thumb does so in what direction?
These ligaments surround the eblow joint.
Ulnar collateral ligament, Radial Collateral ligament, annular ligament
This muscle allows pronation and is located in the distal forearm
Pronator quadratus
This nerve innervates the deltoid and teres minor.
Axillary nerve
It is the "bear hug muscle," with actions of flexion at shoulder, internal rotation of humorous, and adduction of arms.
Pectoralis major
These arteries run down to the hand and provide collateral circulation. Include their locations on the hand
Radial(deep) and ulnar (superficial)
The tendons of this muscle run under the tendon openings of the Flexor Digitorum Superficialis
Flexor Digitorum Profundas
These muscles create the "snuff box." Name them in order of lateral to medial and why this area matters
Abductor Pollicis longus, Extensor Policis Brevis, Extensor Policis Longus
Radial artery and scaphoid
This nerve innervates the posterior arm muscles and posterior forearm muscles
Radial Nerve
These muscles are responsible for abducting the middle digits (what is their innervation?).
Dorsal Interossei (ulnar)
These veins run superficially down the arm (3) Medial to lateral
Basilic, Median, Cephalic
This ligament is responsible for preventing excessive valgus
UCL
The median nerve innervates these muscles in the anterior forearm, with 2 exceptions (what are the exceptions)
Anterior forearm muscles (flexors/pronators)
exceptions: Flexor Carpi Ulnaris, median tendons of FDP
BRACHIAL PLEXUS R.T.D.C.B.
C5-T1
Superior, middle, inferior
Anterior, posterior
Lateral, medial, posterior
Ant: Ulnar, median, musculosckeletal
Post: Axillary, radial
Demonstrate the movements of the thumb
flexion, extension, adduction, abduction
Pathway of blood down to the fingers from the subclavian artery (points of change).
Subclavian-first rib-axillary (circumflex branch)-inferior border of teres major-brachial-deep artery(posterior branch)-radial and ulnar (anterior branch)- deep artery of hand and superficial artery of hand
Flexor Retinaculum, FDS, FDS, FPL
