Nov 3, 2023 · Namely, these muscles are the scalenus anterior (anterior scalene), scalenus medius (middle scalene) and scalenus posterior (posterior scalene). They all belong to the lateral vertebral muscle group. The main functions of these muscles are flexion, lateral flexion and rotation of the neck.

The scalene muscles are a group of three muscles on each side of the neck, identified as the anterior, the middle, and the posterior. They are innervated by the third to the eighth cervical spinal nerves (C3-C8). The anterior and middle scalene muscles lift the first rib and bend the neck to the side they are on.

Feb 10, 2025 · The scalene muscles are three paired muscles (anterior, middle and posterior) located in the lateral aspect of the neck. They form part of the floor of the posterior triangle of the neck. The scalenes act as accessory muscles of respiration and perform flexion at the neck.

Scalene are a group of three pairs of muscles in the lateral neck: scalenus anterior, scalenus medius and scalenus posterior. Sometimes a fourth muscle, the scalenus minimus is present behind the lower portion of the scalenus anterior.

Apr 10, 2023 · The scalene muscles are deep and positioned laterally to the cervical tract. Their innervation is complex, as both the brachial plexus and the cervical plexus are involved in their function. They are multi-articular muscles, and their actions are just as complex and vital.

In this video, we cover the scalene muscles function, location and innervation. Think you’ve got it? Test yourself with this quiz! https://khub.me/n1ugc...more. Kenhub - Learn Human Anatomy...

Objectives: To analyze in depth the anatomy of the scaleni muscles and surrounding structures, and to further document anatomical variations which have been reported in the literature.

Die Musculi scaleni (Skalenusmuskulatur, lat. „Treppe“) sind drei paarig angelegte Halsmuskeln, die von der Halswirbelsäule zu den oberen beiden Rippen ziehen. So bilden sie ein Dach über der Pleura bzw. dem oberen Thorax.

Scalenes are 3 (sometimes 4) muscles on either side of the neck. This is one of those muscles that makes it hard to say which end is the origin and which end is the insertion. Sometimes, we look at the lower attachments as the origin because we flex the neck. Contrarily, we may see the upper attachments as the origin of assisted breathing.

Die Musculi scaleni sind drei gestaffelt angeordnete Halsmuskeln, die bei beidseitiger Kontraktion den Thorax heben und so als Atemhilfsmuskeln fungieren. Bei einseitiger Kontraktion beugen sie die Halswirbelsäule zur ipsilateralen Seite.
