Superficial Back, Deltoid, Scapula - Severson Flashcards
Name the muscle and the nerve/vein/artery that supports it:
Trapezius!
Innervated by the Accessory Nerve - Cranial Nerve XI
The TRANSVERSE CERVICAL arteries and veins provide vasculature
How would you identify an individual with damage to the accessory nerve?
If it is unilateral, they would have a droopy shoulder or weakness in one side. Bilateral would have problems like that bilaterally.
The rhomboid muscles and levator scapuli are supplied by which nerve?
dorsal scapular nerve
What body movements are cuased by the latissimus dorsi?
AND
What nerve and artery supply this muscle?
It extends, adducts and medially rotates the upper extremity.
Thoracodorsal artery/nerve
Primary function of the rhombus major?
Retract the scapula!
Muscle?
Artery?
Nerve?
Anterior Serratus
Lateral Thoracic Artery
Long Thoracic Nerve
What occurs in the case of damage to the long thoracic nerve?
The triangle of asculatation is formed by what structures?
Formed by the Trapezius, Scapula (medial border), Latissimus dorsi
(Good to listen here because lack of dense muscle and bone in the way of lung sounds)
What structures form the quadrilateral space?
What passes through the center of the quadrilateral space?
Teres minor, teres major, long head of triceps, humerus
The axillary nerve passes though it penetrates deep into the deltoid muscle, and the posterior circumflex humeral artery and vein
What structure lies deep to the acromion and deltoid that is used for cushioning?
subacromial bursa
What nerve innervates this muscle?
axillary nerve
4 muscles that make up the rotator cuff?
SITS!
Supraspinatus
Infraspinatus
Teres Minor
Subscapularis
What nerves and arteries are supplying these muscles?
Identify this muscle and its innervation!
Tada!
What nerve innervates this muscle?
Suprascapular nerve
Quickly name the innervations:
1-Trapezius
2- Supra and Infra spinatus
3 - Teres minor and deltoid
4 - Rhomboid major and minor
5 - Levator scapulae
6 - Latissimus dorsi
7 - Teres major
8 - Serratus anterior
1 -Trapezius CN XI – Accessory nerve
2 - Supra/Infra spinatus Suprascapular nerve
3 - Teres minor and Deltoid Axillary nerve
4 - Rhomboid major and minor Dorsal scapular nerve
5 - Levator scapulae Dorsal scapular nerve
6 - Latissimus dorsi Thoracodorsal nerve
7 - Teres major Lower subscapular nerve
8 - Serratus anterior Long thoracic nerve
