The muscle that you are looking for is probably the supraspinatus
The phrase tendon attachment that moves most aptly describes muscle insertion. The trapezius muscle inserts on the acromion and scapular.
A very small scapular spine on the left side and a very large scapular spine on the right side may indicate a muscle size discrepancy or unequal muscle development between the left and right shoulders. This can be caused by asymmetrical strength training, posture imbalances, or underlying musculoskeletal issues that may require further evaluation by a healthcare professional.
The synergist of the trapezius in scapular elevation is the levator scapulae muscle. It works together with the trapezius to elevate the scapula and assist in movements like shrugging the shoulders.
The nerve supply to the levator scapula muscle is from the dorsal scapular nerve (C5) and the third and fourth cervical nerves (C3, C4) that form the cervical plexus.
The trapezius muscle is a superficial muscle of the neck and upper back that acts at the shoulder. It is responsible for movements like shoulder shrugging, scapular elevation, depression, retraction, and rotation.
The most effective exercises for strengthening the levator scapulae muscle include shoulder shrugs, neck stretches, and scapular retraction exercises.
Exercises like scapular retraction, prone shoulder extension, and Y raises can target and strengthen the lower trapezius muscle.
Some effective exercises targeting the pectoralis minor muscle include chest stretches, scapular protraction exercises, and wall push-ups.
Rhomboids Major and Minor are the primary muscles that Adduct the Scapula.
The optimal position for shoulder exercises in the scapular plane is with the arms raised at a 30-45 degree angle in line with the shoulder blades. This position helps to reduce the risk of shoulder impingement and allows for proper muscle activation during the exercises.
Of course one can. Of course, just wearing a Scapular doesn't usually effect anything unless one believes and is living the life that is attached to the scapular. For instance, I wear a black scapular of the Benedictine Order as I am an Benedictine Oblate, and thus must fulfill all the requirements of being an Oblate. I also wear a Scapular medal of the Brown Scapular, although the promises are mostly made towards wearers of the cloth Scapulars. Scapulars are the long apron like piece of fabric that hang from the shoulders to the ground front and back on religious habits. What we normally think of a "scapular" we think of two small pieces of cloth with strings over the shoulders. There is a "five-fold" scapular which is sold that way, and is, literally, five scapulars sew into one: the Brown Scapular of Our Lady of Mt. Carmel (this is the most famous one), the Blue Scapular of the Immaculate Conception, the Black Scapular of the Seven Dolors of Mary, the Red Scapular of the Passion, and the White Scapular of the Most Holy Trinity.
St. Dominic is not the founder of the scapular. The scapular is believed to have originated from the monastic tradition as a form of religious habit. The scapular gained popularity through various Marian apparitions and has become associated with different religious orders, but it was not founded by St. Dominic.
