Superficial Back, Deltoid, Scapular Region Flashcards
Scapula Inferior angle Medial border
Superior angle Superior border
Lateral border Spine Acromion
Supraspinous fossa Suprascapular notch
Humerus Head Anatomical Neck
Surgical neck Greter and lesser tubercle
Deltoid tuberosity
Trapezius Muscle
What is the muscle innerveated by the accessory nerve (CN XI) and transverse cervical A/V
Accessory Nerve
What innervates the trapezius muscle and sternomastoid muscle
It is deep to the trapezeuz, takes origen from C1 to C6 segments
Transverse Cervical Artery
What is the blood supply for the trapezeus muscle?
It takes origen from teh thyrocervical trunck - a branch off of the subclavian artery
Rhomboid Major and Minor Muscles
What muscles lie deep to the trapezius and originate from spinal processes C7 to T5. They are innervated by the dorsal scapular nerve (not on lab test).
Levator Scapulae Muscle
What muscle lies deep to the trapezeus and attaches to C1 - C4 and upper medial border of scapula. It is innervated by the dorsal scapular nerve.
Latissimus Dorsi Muscle
What muscle is innervated by the thoracodorsal nerve and attaches to the vertebae below T6 and attaches to intertubercular groove of humerus?
Serratus Anterior Muscle
What muscle attaches to the lateral boarder of ribs 1-8 and is distally attached to the medial boarder of the scapula? It is innerfvated by the long thoracic nerve.
Traingle Of Auscultation
What is formed by the trapezius, Scapula (medial boarder), and latissiums dorsi? It is a good place to listen to lung sounds.
Deltoid Muscle
What muscle is attached proximally to the lateral third of the calvicle, acromium, and spine of scapula and attaches distally to deltoid tuberosity of the humerus? It is innervated by the axillary nerve.
Axillary Nerve
What nerve runs through the quadrangular space and enters deep to the deltoid muscle to innervated it?
Subacromial (subdeltoid) Bursa
What lies deep to the deltoid muscle and acromion? it allows the humerous to move in the joint.
Infraspinatus Muscle
Supraspinatus Muscle
What muscles attach to their respective fossa on the scapula and attach distally to the greater tubercle on the humerus? They are innervated by the supracapular nerve and artery.
Teres Minor Muscle
Teres Major Muscle
What muscle attaches to the lateral boarder of the scapula and distally to the greater tubercle of the humerous. It is innervated by the axillary nerve.
What muscle attaches to the inferior angle of the scapula and distally to the intertubercular groove of the humerous. It is innervated by the lower subscapular nerve.
Quadrilangular Space
What is formed by the muscles teres minor, teres major, long head of the triceps, and the humerous? The axillary nerve and posterior circumflex A/V pass though it.
Transverse Scapular Ligament
What bridges over the suprascapular notch? The suprascapular nerve passes below it and the suprascapular A/V pass above.
Suprascapular Nerve
Suprascapular Artery/Vein
What nerve passes through the suprascapular notch?
What artery passes above the suprascapular notch and ligament?
Omohyoid Muscle
What muscle attatches to the hyoid bone and the superior boarder of the scapula immediatetly medial to the suprascapular notch?
