Scalene muscles The middle scalene, (or 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.he action of the anterior and middle scalene muscles is to elevate the first rib and laterally flex (bend) the neck to the same side; the action of the posterior scalene is to elevate the second rib and tilt the neck to the same side.

Neck Extensions MUSCLE ACTION. In cervical spine (neck) extension you raise the head from a forward, head down position back to the normal (anatomical) position in which the head is aligned vertically with the spine. In cervical spine hyperextension you increase the cervical curvature by continuing cervical extension.

Sternocleidomastoid It inserts into the temporal bone's mastoid process near the ear and the base of the skull, and it stretches the entire length of the neck. This muscle helps the neck to turn to the side, flex to the side, and bend forward. Two nerves serve the sternocleidomastoid muscle. For motor functions (movement), the muscle uses the accessory nerve. The cervical plexus nerve provides for sensory function, which includes proprioception — the sense we have of our body’s position and movement within the space around us.

Trapezius This muscle is named for its trapezoid shape. The trapezius muscle is a postural and active movement muscle, used to tilt and turn the head and neck, shrug, steady the shoulders, and twist the arms. The trapezius elevates, depresses, rotates, and retracts the scapula, or shoulder blade. Innervation of the trapezius is derived from the spinal accessory nerve.

Muscles of the Head and Neck Working individually, these muscles rotate the head or flex the neck laterally to the left or right. Neck muscles contract to adjust the posture of the head throughout the course of a day and have some of the greatest endurance of any muscles in the body. Prepared by Tim Taylor, Anatomy and Physiology Instructor.

Neck Muscles Neck Muscles. The neck is the part of the human body that attaches the head to the rest of the body. It is made up of many muscles that are connected from the head to the torso of the body. The purpose of the neck muscles is either to allow for neck movement or to provide structural support for the head. The motion is either rotation, meaning side-to-side; lateral flexion, meaning ear to shoulder; flexion, meaning chin to sternum; and hypertension, meaning looking up. Here is the list of muscles in the neck and head area: 1  Longus colli and capitis – this is found in the anterior neck area and is used for flexion. 2  Infrahyoid and suprahyoid – these muscles are for opening the jaw and for flexing the neck, and are found in the anterior neck area.

- Muscles of the Neck: Head Movements. Head is moved by muscles originating from the axial skeleton. Major head flexor is the sternocleidomastoid muscles. Synergists to head flexion are the suprahyoid and infrahyoid. Lateral head movements are accomplished by the sternocleidomastoid and. scalene muscles. Head extension is accomplished by the deep splenius muscles and aided by. the superficial trapezius.

- These include the buccinator, masseter, temporalis and pterygoid muscles. Below the muscles of your face are neck muscles that help support and move your head. These include the sternocleidomastoid muscles, which flex your neck, move your head from shoulder to shoulder and turn your face from side to side. Moving around to the back, we have axial muscles of the spinal column.

Muscle of neck n vertebral column When all the erector spinae muscles contract together, they extend or hyperextend the vertebral column. the trunk, neck or head move laterally toward the contracting side. The movement is accomplished because the articular facets of the vertebrae glide on each other. Controls flexion, lateral flexion and rotation.

Muscles of the Vertebral Column: Support & Movement The longissimus group of muscles helps to extend the neck and vertebral column, as these muscles originate on vertebrae and insert on more superior vertebrae and even some ribs.et's take a look at these muscles. If we peel away the trapezius and the latissimus dorsi muscle that are on the superficial part of the back, we can see the muscles responsible for our posture. The erector spinae is a group of muscles that work together to extend the vertebral column and thus maintain good posture.

Original articleEffects of latissimus dorsi length on shoulder flexion in canoeists, swimmers, rugby players, and controls Background. Shoulder flexion requires an optimal length of the latissimus dorsi muscle in order to allow full lateral rotation of the humerus and upward scapular rotation. If shoulder flexion (in an externally rotated position) is restricted, this may predispose the individual to shoulder pathology.

Computer Neck Syndrome: Postural Causes of a Common Malady The most common components of hypertonicity, as they relate to the neck and upper back, are our old friends the upper trapezius and levator scapulae. As I described last month, these two muscles are shoulder elevators; when they get hypertonic and tight, these muscles cause a shrugged posture.
