Muscles of the Upper Limb
What are the rotator cuff muscles?
SITS
Supraspinatus
Infraspinatus
Teres Minor
Subscapularis
They call me the 'Honeymoon Muscle'
Sartorius
- flexes and abducts the hips and flexes the knee
I'm a sesamoid bone
Patella
This nerve arises from the lateral cord of the brachial plexus and supplies the biceps brachii, brachialis, and coracobrachialis.
What is the musculocutaneous nerve?
This space lies beneath the deltoid and teres minor, and the axillary nerve passes through it with the postrior circumflex humeral artery
What is the quadrangular space?
What is the IDK muscle?
Levator Scapulae
I am the largest muscle in the body. Who am I?
Gluteus Maximus
This artery is a continuation of the subclavian artery after it passes the lateral border of the first rib.
What is the axillary artery?
Injury to the upper trunk of the brachial plexus (C5-C6) results in this condition.
What is 'Waiter's Tip' or 'Erb's Palsy'?
(What if it was a lower trunk (C8-T1) injury?
This infection involves the spaces in the fingertips, causing throbbing, tense swelling, and tenderness due to infection. It can lead to osteomyelitis if not treated.
What is a felon?
I am long, I am short, I look like pop-eye when I'm injured. What am i?
Biceps Brachii
They call us the lateral rotators of the hip. I am superior gemellus, obturator internus, inferior gemellus... we're missing a few, who are they?
Piriformis
Quadratus Femoris
This arterial arch in the hand receives contributions from the radial artery and supplies the thumb and index finger.
What is the deep palmar arch?
I supply the cremasteric reflex.
Genitofemoral nerve (L1,2)
The pressure rises, and vessels are damaged. I appear as a flexed elbow and wrist, with thumb abduction, pronated forearm, and metacarpal extension with IP flexion.
What is a Volkmann's Contracture?
We all contribute to abduction of the arm. Who are we?
Supraspinatus up to 15 degrees
Deltoid up to 90 degrees
Trapezius more than 90 degrees
Name the ligaments and muscles that originate from the:
ASIS
AIIS
ASIS - inguinal ligament, sartorius
AIIS - iliofemoral ligament, straight head of rectus femoris
This superficial vein runs along the medial side of the arm and forearm, draining into the brachial or axillary vein.
What is the basilic vein?
The adductor brevis separates me into an anterior and posterior division
What is the obturator nerve?
I punctured my hand with a knife. A red, hot, dicoloured 'button' appears in my palm. That spreads to look like an hourglass
What is the midpalmar and thenar spaces?
List the 20 muscles in the forearm- be specific and mention my nerve supply
Pronator Teres
Flexor carpi radialis
Palmaris Longus
Flexor Carpi Ulnaris
Flexor Digitorum Superficialis
Flexor Digitorum Profundus
Flexor Pollicis Longus
Pronator Quadratus
All median except medial half of FDP and FCU
Brachioradialis, Extensor Carpi Radialis Longus, Extensor Carpi Radialis Brevis, Extensor Digitorum, Extensor Digiti Minimi, Extensor Carpi Ulnaris, Anconeus, Supinator, Adductor Pollicis Longus, Extensor Pollicis Brevis, Extensor Pollicis Longus, Extensor Indicis
All radial nerve
Students remember us as 'Tom Has A NursE'. We tunnel through the extensor retinaculum.
Tibialis Anterior
Hallucis Longus
Anterior Tibial artery
deep peroneal Nerve
Extensor Digitorum Longus
This artery is the terminal branch of the popliteal artery that runs deep in the posterior compartment of the leg alongside the fibula.
What is the fibular (peroneal) artery?
I can't plantarflex nor stand on my toes!
What is the damage to the tibial nerve?
What are the boundaries of the axillary space?
Anterior; Pec Major and Minor
Posterior; scapularis, teres minor, latissimus dorsi
Lateral; intertubercular sulcus
Medial; serratus anterior and thoracic wall
