What are four muscles that do contralateral rotation of the neck
What muscle performs contralateral rotation of the neck?
If you look straight ahead, then turn your head to the side, this is contralateral head rotation. The muscles involved include the sternocleidomastoid, rotatores longi, semispinalis capitis, and semispinalis cervicis. Scalenes acting in contralateral head rotation.
Which muscle causes rotation to the opposite side?
Sternocleidomastoid Function
One SCM can also turn, or rotate, your head to the opposite side. For example, when you rotate or turn your head to the right, your left SCM is contracting.
What muscle can flex the neck and rotate the neck to the opposite side?
The major muscle that laterally flexes and rotates the head is the sternocleidomastoid. In addition, both muscles working together are the flexors of the head. Place your fingers on both sides of the neck and turn your head to the left and to the right. You will feel the movement originate there.
What are the main muscles for supporting and rotating your neck?
In the cervical spine, the erector spinae muscles play key roles in supporting posture, rotating the neck, and extending the neck backward. Deep cervical flexors. The muscle group is comprised of the longus capitus and longus colli muscles, which run down the front of the cervical spine.
What are the 4 quadriceps muscles?
quadriceps femoris muscle, large fleshy muscle group covering the front and sides of the thigh. It has four parts: rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius.
What muscles are in the side of your neck?

Which muscle is involved with rotating and flexing the neck quizlet?
Which neck muscles flex the neck? The anterolateral neck muscles flex the neck (sternocleidomastoid; anterior, middle, and posterior scalenes).
What muscles are in the front of your neck?
Muscles in the front of the neck are the suprahyoid and infrahyoid muscles and the anterior vertebral muscles (see the images below). The suprahyoid muscles are the digastrics, stylohyoid, mylohyoid, and geniohyoid. The infrahyoid muscles are the sternohyoid, sternothyroid, thyrohyoid, and omohyoid.
What is the sternocleidomastoid muscle?
The sternocleidomastoid muscle (SCM) is an important landmark in the neck which divides it into an anterior and a posterior triangle. This muscle binds the skull to the sternum and clavicle.
Which muscle is involved with rotating and flexing the neck?
sternocleidomastoid muscle
The sternocleidomastoid muscle, commonly called the SCM, attaches to the bony mastoid process on the skull and travels down the front of the neck to connect to the sternum and collarbone. The SCM muscle can help in head rotation and tilting the chin.
Which muscle is responsible for flexing the neck quizlet?
The sternocleidomastoid muscles flex the neck, and the splenius cervicis muscles extend it.
What four primary muscles allow extension of the neck?
Muscles of the Spinal Column
| CERVICAL MUSCLES | FUNCTION | NERVE |
|---|---|---|
| Sternocleidomastoid | Extends & rotates head, flexes vertebral column | C2, C3 |
| Scalenus | Flexes & rotates neck | Lower cervical |
| Spinalis Cervicis | Extends & rotates head | Middle/lower cervical |

What are the movements of the neck?
Cervical flexion: bending the head forward towards the chest. Cervical extension: bending the head backward with the face towards the sky. Cervical rotation: turning the head to the left or the right. Cervical side-bending: tipping the head to the side or touching an ear to the shoulder of the same side.
How do you rotate your neck?
Neck Rotation: Rotate head gently and slowly from side to side. Do not turn head completely to either side, keep motion small. Keep chin level with ground without letting chin drop to chest. Repeat 10 times.

- Extension. The cervical spine straightens or moves directly backward with the chin tilting up. …
- Rotation. The cervical spine and head turn to one side. …
- Lateral flexion.
How many movements are in the neck?
These six movements may be slowly performed occasionally to stretch the neck ligaments if they tend to feel tight. The movements can be performed at any time by patients who have not had fusions. If you have had a fusion, your surgeon will discuss with you when you can start them.
What is contralateral lateral flexion?
For a suspected nerve problem at the wrist (eg., CTS), cervical contralateral lateral flexion (CCLF) would constitute such a movement in which a change in sensory response might occur in the forearm or hand without changing tension or excursion in adjacent structures such a muscles or tendons.
What is medial and lateral rotation?
Medial and lateral rotation of the upper limb at the shoulder or lower limb at the hip involves turning the anterior surface of the limb toward the midline of the body (medial or internal rotation) or away from the midline (lateral or external rotation).
What movement is abduction?
Abduction is any motion of the limbs or other body parts that pulls away from the midline of the body. Swinging the hands from the side of the body up to the shoulder or higher is abduction. For fingers and toes, abduction spreads the digits away from the hand or foot’s centerline of hand or foot.
What is ipsilateral flexion of neck?
Similar to the middle scalene, the main function of the posterior scalene is ipsilateral flexion of the neck when acting from below, and stabilization or elevation of the second rib when acting from above.
