The latissimus dorsi is a potential source of muscle for breast reconstruction surgery after mastectomy (e.g., Mannu flap) [12] or to correct pectoral hypoplastic defects such as Poland's syndrome. [13] [14] An absent or hypoplastic latissimus dorsi can be one of the associated symptoms of Poland's syndrome. [15] [16]
The insertion of the latissimus dorsi muscle is found along the floor of the bicipital groove. The teres major muscle inserts on the medial lip of the groove. [citation needed] It runs obliquely downward, and ends near the junction of the upper with the middle third of the bone. It is the lateral wall of the axilla. [2]
The lesser tubercle provides insertion to subscapularis muscle. Both these tubercles are found in the proximal part of the shaft. The crest of the lesser tubercle forms the medial lip of the bicipital groove and is the site for insertion of teres major and latissimus dorsi muscles.
It penetrates into the substance of the latissimus dorsi muscle near the lateral border of scapula. [5] It follows the course of the subscapular artery, along the posterior wall of the axilla to the latissimus dorsi muscle, [1] in which it may be traced as far as the lower border of the muscle.

Latissimus dorsi: originates at the supraspinous ligament & thoracolumbar fascia, inserts in the humerus. Antagonist to brachiocephalicus. Supports the back, helps to pull the body of the horse forward when a limb is extended and placed on the ground, also helps to flex the scapulohumeral joint.
The axillary arch is an arch-shaped anatomical variant of the latissimus dorsi muscle of the human back. [6] [7] Its shape varies, but its defining characteristics are its origin from the latissimus dorsi muscle, its insertion close to or on the upper anterior part of the humerus, and that it crosses the neurovascular bundle associated with the axillary nerve from dorsomedial to ventrolateral. [6]
The thoracolumbar fascia is thought to be involved in load transfer between the trunk and limb (it is tensioned by the action of the latissimus dorsi muscle, gluteus maximus muscle, and the hamstring muscles), and lifting. [1]: 814–815 It is endowed with nociceptive receptors, and may be involved in some forms of back pain. [1]: 814–815
Apart from the above neck muscles, the following muscles have also been observed contributing to respiration: serratus anterior, pectoralis major and pectoralis minor, trapezius, latissimus dorsi, erector spinae, iliocostalis, quadratus lumborum, serratus posterior superior, serratus posterior inferior, levatores costarum, transversus thoracis ...
