What muscles stabilize the neck?
Deep cervical flexors. These muscles, also called the longus capitus and longus colli, are located along the front of the cervical spine and help stabilize the neck. When weakened, the deep cervical flexors lengthen as the chin tilts away from the neck, often called “chin poking.”
What muscles stabilize the head?
Splenius capitis and splenius cervicis: Strap-like muscles in the back of your neck that help you extend and rotate your head. Suboccipital muscles: Four muscles just below the occipital bone at the base of your skull. They help extend your head in different directions.
Where are the neck extensor muscles?
The deep neck extensors muscles belong to the deepest layer of intrinsic back muscles, the transversospinalis group. They provide posterior support of cervical lordosis in synergy with the deep neck flexors and prevent a forward head position.
What are neck extensor muscles?
The superficial extensor muscles are the trapezius which also elevates the shoulder, elevates the scapula and laterally flexes the neck and the levator scapula which mainly elevates the shoulder.
How do you stabilize cervical instability?

- Surgery.
- Physical Therapy.
- Strengthening Exercises.
- Prolotherapy.
What neck muscles hold your head up?
The trapezius muscle can be involved in extending the head upward or neck backward, rotating/turning the head, or lifting the shoulder blade.
Which muscles control neck movement?
The scalene muscles help with neck flexion and side bending. The deep cervical flexors are a muscle group consisting of the longus capitus and longus colli muscles, which run down the front of the cervical spine. The deep cervical flexor muscles help flex the neck forward as well as stabilize the cervical spine.
What do flexors and extensors control?
Muscles can pull bones, but they can’t push them back to the original position. So they work in pairs of flexors and extensors. The flexor contracts to bend a limb at a joint. Then, when the movement is completed, the flexor relaxes and the extensor contracts to extend or straighten the limb at the same joint.
Can cervical neck instability be cured?
Cervical instability is a medical condition in which loose ligaments in your upper cervical spine may lead to neuronal damage and a large list of adverse symptoms. If you have cervical instability, you may be experiencing migraines, vertigo, or nausea. Fortunately, this condition is treatable, though not curable.
What causes you to not be able to hold your head up?
The dropped head syndrome (DHS) is a disabling condition caused by severe weakness of the neck extensor muscles causing progressive reducible kyphosis of the cervical spine and the inability to hold the head up. Weakness can occur in isolation or in association with a generalized neuromuscular disorder.
What does the sternocleidomastoid muscle do?
Function. Rotation of the head to the opposite side or obliquely rotate the head. It also flexes the neck. When acting together it flexes the neck and extends the head.
What do extensor muscles do?
extensor muscle, any of the muscles that increase the angle between members of a limb, as by straightening the elbow or knee or bending the wrist or spine backward. The movement is usually directed backward, with the notable exception of the knee joint.
