Middle scalene or scalenus medius (Latin: musculus scalenus medius), is the largest and longest muscle in the scalene group of lateral neck muscles. Often penetrated by the dorsal scapular and long thoracic nerves, it is deeply placed, lying behind sternocleidomastoid.

2023年11月3日 · The scalene muscles are the three muscles found on each side of the neck, spanning between the transverse processes of the cervical vertebrae and the upper two ribs. Namely, these muscles are the scalenus anterior (anterior scalene), scalenus medius (middle scalene) and scalenus posterior (posterior scalene).

2024年11月25日 · The middle scalene is the largest and longest of the three scalene muscles. It has several long, thin muscle bellies arising from the cervical spine, which converge into one large belly that inserts into the first rib.

The middle scalene, (Latin: scalenus medius), is the largest and longest of the three scalene muscles. The middle scalene arises from the posterior tubercles of the transverse processes of the lower six cervical vertebrae.

To target the posterior scalene, turn your face toward the arm that is pulling; To target the anterior scalene, turn your face away from the pulling arm. To target the middle scalene, look straight up at the ceiling, or just slightly toward the pulling arm.

2023年4月10日 · The middle scalene originates from the transverse processes of the last six cervical vertebrae, between the anterior and posterior tubercle, inserting itself on the upper face of the first rib, posterior to the sulcus of the subclavian artery.

The middle scalene (Latin: musculus scalenus medius) is a neck muscle situated between the anterior and posterior scalene muscles. It is classified as the scalene muscle and one of the lateral neck muscles. The middle scalene is the largest and longest of the scalene group.

2022年7月22日 · The scalenus medius (middle scalene) muscle is one of the three scalene muscles in the neck. Summary. origin: transverse processes of lower six cervical vertebrae (C2-C7) insertion: upper surface of first rib; action (similar to scalenus anterior muscle) raises first rib (respiratory inspiration) acting bilaterally: neck flexion

2022年10月16日 · The scalene muscles are a group of three closely related neck muscles. origin: transverse processes of mid to lower cervical vertebrae (C2-C7). insertion: first or second ribs. The anterior and middle inserts on the first rib, whereas the posterior attaches on the second rib. innervation: ventral rami of cervical nerves (C3-C8). 1.

2021年6月17日 · The middle scalene is the longest and largest of the scalene muscles. The clavicle and omohyoid muscle cross the middle scalene anteriorly and it is separated from the anterior scalene by the subclavian artery and the ventral rami of the cervical spinal nerves.
