Furthermore, there was no alteration in the relationship of the fascicles with adjacent vascular structures, or in their deep location to the clavipectoral fascia and
pectoralis minor. The fascicles lying deep to the clavipectoral triangle emitted their terminal branches from the beginning of the upper margin of the axillary fossa.
(5) Pectoralis major and
Pectoralis minor (boneless, skinless).
Laterally,
pectoralis minor inserts onto the coracoid process, and the neurovascular bundle can be found lying posterior to the muscle and inferior and medial to the coracoid process.
The
pectoralis minor muscle is positioned posterior to the pectoralis major muscle, extending from the third, fourth or fifth ribs to the coracoid process of the scapula.[3]
Loukas showed axillary arch originated from the latissimus dorsi with extensive branching, inserting into three of the more common sites; the pectoralis major,
pectoralis minor and coracoid process.
The legend has the origin of the data and a table to the left has the surgical division of the groups of lymph nodes in relation to the
pectoralis minor muscle (Roberts, 2010; Standring, 2011).
It exits the lateral cord of the brachial plexus and courses anterior to the axillary artery and medial to the
pectoralis minor, then travels distally and posterior to the PM before entering the muscle 12.5 cm medial to the humeral insertion.
To most effectively apply this technique to the pectoralis major, make sure that the client's scapula is stabilized on the table; to most effectively apply this technique to the
pectoralis minor, have the client move farther to the side so that their scapula is off the table and free to move.
Coracoid-based
pectoralis minor and levator scapulae muscles are usually tight.
Near the lateral margins of the
pectoralis minor muscle, each cord terminates in 2 major nerve branches (Figure 1).
