[스크랩] 전거근 serratus anterior muscle

1. 전거근은 어깨 익상견의 주범

2. 전거근과 외복사근은 발생학적으로 기원이 같음.

3. 장흉신경 마비는 목디스크, axilla의 임파절제술, 유방암 수술 등으로 흔히 발생

4. 견갑골 안정화 근육 

5. 상부, 중부, 하부 전거근섬유로 구분

6. 전거근의 길항근은 "능형근" 

7. "big swing muscle" or "boxer's muscle"

8. 팔을 overhead로 들때, 견갑골을 upward roation시키는 근육

The serratus anterior is a muscle that originates on the surface of the 1st to 8-9th ribs at the side of the chest and inserts along the entire anterior length of the medial border of the scapula.

- 전거근은 늑골 1번~9번의 가슴부분에서 기시하여 견갑골의 내측연에 종지함.

Serratus anterior normally originates by nine or ten slips from either the first to ninth ribs or the first to eighth ribs. Because two slips usually arise from the second rib, the number of slips is greater than the number of ribs from which they originate.^[1]

The muscle is inserted along the medial border of the scapula between the superior and inferior angles along with being inserted along the thoracic vertebrae. The muscle is divided into three named parts depending on their points  of insertions:^[1]

1. the serratus anterior superior is inserted near the superior angle
2. the serratus anterior intermediate is inserted along the medial border
3. the serratus anterior inferior is inserted near the inferior angle.

- 전거근은 3분지로 나뉘는데 전상 전거근은 견갑골 상각에 부착

- 전중 전거근은 견갑골의 내측연을 따라 부착

- 전하 전거근은 견갑골 하각에 부착

The serratus anterior is innervated by the long thoracic nerve (Nerve of Bell), a branch of the brachial plexus. The long thoracic nerve travels inferiorly on the surface of the serratus. The nerve is especially vulnerable during certain types of surgery (for example, during lymph node clearance from the axilla (e.g., in case of axillary dissection in a surgery for breast cancer)). Damage to this nerve can lead to a winged scapula.

- 전거근은 상완신경총의 가지인 장흉신경의 지배

- 장흉신경은 액와의 림프절 절제수술하다 흔히 손상됨. 장흉신경이 손상되면 익상견을 유발할 수 있음. 

All three parts described above pull the scapula forward around the thorax, which is essential for anteversion of the arm. As such, the muscle is an antagonist to the rhomboids. However, when the inferior and superior parts act together, they keep the scapula pressed against the thorax together with the rhomboids and therefore these parts also act as synergists to the rhomboids. The inferior part can pull the lower end of the scapula laterally and forward and thus rotates the scapula to make elevation of the arm possible. Additionally, all three parts can lift the ribs when the shoulder girdle is fixed, and thus assist in respiration. ^[1]

The serratus anterior is occasionally called the "big swing muscle" or "boxer's muscle" because it is largely responsible for the protraction of the scapula — that is, the pulling of the scapula forward and around the rib cage that occurs when someone throws a punch.

The serratus anterior also plays an important role in the upward rotation of the scapula, such as when lifting a weight overhead. It performs this in sync with the upper and lower fibers of the trapezius.^[2]
