Where are scalene muscles located?
The scalene muscles are located deep in relation to the sternocleidomastoid muscle, lateral to the cervical spine, connecting the vertebrae to the first two ribs. The deep fascia or prevertebral fascia envelop the scalene muscles.
How many scalene muscles does everyone have on each side of the neck?
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.
Which muscle attaches to the scalene tubercle?
scalenus anterior
The scalene tubercle is a small projection that runs along the medial border of the first rib between two grooves, which travel anteriorly for the subclavian artery and posteriorly for the subclavian vein. It projects outward medially, and is the site of insertion for scalenus anterior, and scalenus medius.
How many scalene muscles are there?
Anatomical terms of muscle The scalene muscles are a group of three pairs of muscles in the lateral neck, namely the anterior scalene, middle scalene, and posterior scalene. They are innervated by the fourth, fifth, and sixth cervical spinal nerves (C4-C6).
What is scalene muscle?
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.
How many muscles does scalene have?
Scalene are a group of three pairs of muscles in the lateral neck: scalenus anterior, scalenus medius and scalenus posterior.
What does scalene pain feel like?
Just like the pain of a heart attack spreads from the heart into the shoulder & arm, the pain of painful scalene muscles spreads throughout the chest, upper back & chest, the arm & hand & the side of the head. Pain referred to the back may feel like a penetrating pain stabbing through the torso.

Where is the anterior scalene muscle located?
The anterior scalene muscle (Latin: scalenus anterior), lies deeply at the side of the neck, behind the sternocleidomastoid muscle.
What is the scalenus minimus muscle?
A fourth muscle, the scalenus minimus (Sibson’s muscle), is sometimes present behind the lower portion of the anterior scalene. The anterior and middle scalene muscles lifts the first rib and bends the neck to the same side as the acting muscle; the posterior scalene lifts the second rib and tilts the neck to the same side.
What is the function of the Scalenus medius and scalenus posterior?
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.
