What is Scalenus front?

SCALENUS, also known as front scalene muscles or scalenus anticus, is one of the three scalen or scalen muscles. These are pairs of neck muscles that function as side structures in this part of the body. The front Scalenus, which is the middle of the three, is named for its position, which is close to the front neck and lines it. The front scalenus is clinically significant because of its connection with certain muscle disorders, such as scalenus anterior syndrome and thoracic syndrome, which involves compression of nerves or blood vessels. This process is known as a transverse process that is responsible for connecting ligaments and muscle. The specific vertebral area of ​​origin is second on the seventh vertebra or C2 to C7. From there, Scalene's muscles go to the first two ribs of the body. It is placed behind the sternocleidomastoid muscle that connects to the scaleni and gives the neck the ability to be flexible and rotate.

Especially Scalenus front comes from the pre -nsItem tubernial cuts of cross processes C3 to C6. Go down and almost vertically, is led by a tendon to Scalene Tubercle, which has the first rib at its inner border. It is also inserted into the upper surface of this rib just behind the collarbone or collar bone. The front arms C5 and C6 give the nerves of this muscle.

There are two important features performed by the front scalenus. First, it contributes to the stabilization of the first rib in which it is inserted. Secondly, in cases where other muscles fix the first rib, the front of the front calculates such a state of assiboding in bending and neck rotation.

other scalene muscles are scalenus medius and scalenus rear. Scalenus Medius is the largest of three and its place of origin is the rear of the tubernal C2 to C7 in transverse processes. It is mainly responsible for contributing to normal breathing because it provides an increase in the upper ribs. The smallest of Scalen is the back Scalenus, also known as Scalenus posticus. This comes from the rear tubers on the transverse processes C4 or C5 to C7 and goes to drOhého ribs.
