What is flexion of the head?
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.
What muscle flexes the head?
sternocleidomastoid
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 is flexion and extension of neck?

What is lateral flexion of the head?
Movement of a body part to the side is called lateral flexion. This type of movement is commonly associated with the neck and spine. For example, when you move your head toward one of your shoulders or bend your body sideways, you’re performing a lateral flexion.
What is an example of flexion?
Flexion – bending a joint. This occurs when the angle of a joint decreases. For example, the elbow flexes when performing a biceps curl. The knee flexes in preparation for kicking a ball.
What is dorsiflexion and plantar flexion?
The term plantar flexion refers to the movement of the foot in a downward motion away from the body. It also enables the opposite movement, dorsiflexion, which is the movement of the foot toward the leg. Your ankle joint supplies the power for 40% to 70% of your forward movement during walking.
What flexes and rotates the head?
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.
What flexes the vertebral column?
| Name of Muscle | Action |
|---|---|
| Iliocostalis | Extends and flexes laterally vertebral column |
| Longissimus | Extends and flexes laterally vertebral column |
| Spinalis | Extends vertebral column |
| Semispinalis | Extends neck and vertebral column |
What is flexion of knee?
A flexion deformity of the knee is the inability to fully straighten or extend the knee, also known as flexion contracture. Normal active range of motion (AROM) of the knee is 0° extension and 140° flexion.
What is flexion of the elbow?
When your forearm moves toward your body by bending at your elbow, it’s called elbow flexion. The opposite movement is called elbow extension. The three bones involved in elbow flexion are the: humerus, in your upper arm. ulna, on the little finger side of your forearm.

What muscles are used to turn your head?

What are the major head flexors?
The major head flexors are the sternocleido mastoid muscles, with the help of the muscles attached to the hyoid bone . The arrangement of a muscle’s fascicles determines its range of motion and power. Muscle power does not depend on the direction of the fascicles.
What is the prime mover of head flexion?
The splenius capitis muscle is a prime mover for head extension. The splenius capitis can also allow lateral flexion and rotation of the cervical spine.
What is flexion position?
Flexion is an anatomical term that refers to a movement produced at a joint by a muscle or muscles that causes the angle of the joint to decrease relative to its anatomical position. For example, when a person is standing normally, the hip joint is considered to be in a neutral or 180-degree position.
