The serratus anterior is a muscle of the chest. It originates at the side of the chest from the upper 8 or 9 ribs; it inserts along the entire length of the anterior aspect of the medial border of the scapula. It is innervated by the long thoracic nerve from the brachial plexus. The serratus anterior acts to pull the scapula forward around the ...
When the serratus anterior contracts, upward rotation, abduction, and weak elevation of the scapula occurs, allowing the arm to be raised above the head. [4] The long thoracic nerve innervates the serratus anterior; therefore, damage to or impingement of this nerve can result in weakening or paralysis of the muscle. [5]
The serratus punch is an exercise that works scapular protraction using the serratus anterior muscle and to a lesser extent the pectoralis minor. [ 1 ] [ 2 ] The exercise even performed at maximum voluntary isometric contraction did not increase pain in one study in people with shoulder pain. [ 3 ]
It originates from the axillary artery and follows the lower border of the pectoralis minor muscle [1] to the side of the chest to supply the serratus anterior muscle, [2] pectoralis major muscle [3] and pectoralis minor muscle, [4] and sends branches across the axilla to the axillary lymph nodes and subscapularis muscle.
"Front and lateral raises target your shoulders, but front raises also require input from the serratus anterior muscles, which run along the sides of your ribcage and underneath your armpits ...
The scapulocostal joint (also known as the scapulothoracic joint) is a physiological joint formed by an articulation of the anterior scapula and the posterior thoracic rib cage. It is musculotendinous in nature and is formed predominantly by the trapezius, rhomboids and serratus anterior muscles.
When it comes to reducing weight, it depends on the kind of exercise you’re doing. For compound movements, you might drop more weight, like 10 to 15 pounds, and for isolation movements, you ...
Deep muscles of the chest, including pectoralis minor, serratus anterior, and subclavius (Gray 1918) Pectoralis major is a thick, fan-shaped or triangular convergent muscle, which makes up the bulk of the chest muscle. It lies under the breast. It serves to flex, extend, and rotate the humerus, the long bone of the upper arm.
