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 latissimus dorsi performs extension and adduction of the arm directly to the spinal fascia. It bypasses the scapulae unlike other muscles which perform this function, so work performed by this muscle will not contribute to muscles that affect the scapulae.
Build big, strong latissimus dorsi muscles takes more than just pull ups. Add these lat exercises and workouts to your routine to add major size and strength.
latissimus dorsi: 2 1 teres major: Upper limb, Shoulder, Right/left posterior surface of inferior angle of scapula: medial lip of intertubercular sulcus of humerus: subscapular artery, circumflex scapular artery: lower subscapular nerve (segmental levels C5 and C6) internally rotates humerus: 2 1 supraspinatus: Upper limb, Shoulder, rotator ...
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.

[1] [3] [4] The trapezius, infraspinatus, and brachialis muscles are most active at the beginning of the pull-up; the latissimus dorsi, teres major, and biceps brachii reach peak activity during the middle of the movement, and the triceps brachii and subscapularis experienced maximum activity at the top of the movement.

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]
Minor core muscles include the latissimus dorsi, gluteus maximus, and trapezius. ... An example of static core function is firing a rifle in the prone position. To ...
