Fracture of the clavicle can cause what?
Drooping of the shoulder due to inability of trapezius to hold it up, SCM elevates medial fragment, pectoralis major pulls lateral fragment medially.
Common fracture of the scapula involves what?
Involves the protruding subcutaneous acromion.
Pectoral fascia leaves the lateral border of pectoralis major and becomes what?
The axillary fascia
What layer of fascia is deep to pectoralis major?
Clavipectoral fascia, it descends from the clavicle, encloses the subclavius and than pec minor, than it becomes continuous with axillary fascia.
What is the costocoracoid membrane?
It is part of the clavipectoral fascia between subclavius and pec minor.
What is the suspensory ligament?
It is part of the clavipectoral fascia inferior to pec minor that supports the axillary fascia and pulls it and the skin inferior to it upward during abduction.
What is the axillary fossa?
Formed by the suspensory ligament of axilla during abduction of the arm.
Deltoid Fascia
Invests the deltoid and is continuous with the pectoral fascia (anteriorly) and infraspinous fascia (posteriorly).
What is continuous with the deltoid, pectoral, axillary, and infraspinous fasciae that encloses the arm like a snug sleeve?
The brachial fascia
What extends from the deep surface of the brachial fascia and attach to the central shaft and medial and lateral supra-epicondylar ridges of the humerus?
The medial and lateral intermuscular septa.
The intermuscular septa divides the arm into?
Anterior (flexor), and Posterior (Extensor) compartements.
What vein is commonly used for venipuncture?
Medial cubital vein
