[Best Answer]: Where does lateral flexion occur?

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.

Which muscles do lateral flexion?

All trunk flexors and extensors can produce lateral flexion when acting unilaterally. The major muscles involved are the rectus abdominis, external and internal obliques, erector spinae, semispinalis thoracis, latissimus dorsi, deep posterior spinal muscles, quadratus lumborum, and psoas.

What causes lateral flexion of the spine?

The origins and insertions of the various deep back muscles overlap extensively, and when they contract, entire regions of the vertebral column can be moved simultaneously (causing extension or hyperextension). When these muscles contract on only one side of the vertebral column, lateral flexion occurs.

Where does lateral flexion occur in the vertebral column?

Lateral flexion is free at the atlanto-occipital joint, cervical and lumbar spine, but less free in the thoracic spine. Rotation is greatest at the specialised atlantoaxial articulations, and to a lesser degree in the cervical and lumbar spine.

What is lateral flexion of the lumbar spine?

Lumbar Spine. Lateral flexion is side bending in the frontal/ coronal plane. The quadratus lumborum, oblique abdominals, and erector spinae are considered the primary lateral flexors. Note that the internal and external obliques on the same side work to produce the same motion.

Can you laterally flex the hip?

The only part of quadriceps which acts as a hip flexor is this part, rectus femoris. … Sartorius helps to flex the hip. It can also produce lateral rotation at the hip.

Where is the origin of the sternocleidomastoid?

Origin and insertion

The sternal head originates from the manubrium sterni, while the clavicular head from the medial third of the clavicle. The insertion is the lateral surface of the mastoid process of the temporal bone and the lateral half of the superior nuchal line of the occipital bone.

Where is the anterior longitudinal ligament?

The anterior longitudinal ligament lies on the ventral surface of the vertebral body through the entire length of the vertebral column, it also sweeps around the lateral aspect of the vertebral bodies (Hayashi et al., 1977).

Where does rotation occur in the spine?

Rotation is greatest at the specialized atlantoaxial articulations, and to a lesser degree in the cervical and lumbar spine.

What is the primary flexor of the spine?

A major flexor of the vertebral column is the rectus abdominis. The rectus abdominis is a large flat muscle on the anterior of the trunk.

Which of the following are lateral flexion yoga poses?

What movements occur in the thoracic region?

In the thoracic spine the facet joints are orientated in the coronal plane, which means the primary movements of the thoracic spine are axial rotation and lateral flexion (i.e. twisting and side bending of the spine).

What are the primary and secondary curves of the spine?

The vertebral column is curved, with two primary curvatures (thoracic and sacrococcygeal curves) and two secondary curvatures (cervical and lumbar curves).

What is bilateral flexion?

Bilateral Flexion – YouTube

What joint can horizontal flexion occur?

Horizontal flexion: this only happens at the shoulder joint and occurs in the transverse plane. When an arm is held out to the side parallel to the floor and then pulled across the chest, that would be horizontal flexion.

Where is the thoracic area of the spine?

The thoracic spine is located in the upper and middle part of the back. Twelve vertebrae are located in the thoracic spine and are numbered T-1 to T-12. Each number corresponds with the nerves in that section of the spinal cord: T-1 through T-5 nerves affect muscles, upper chest, mid-back and abdominal muscles.

Where is the lateral aspect of the hip?

The hip region is located lateral and anterior to the gluteal region, inferior to the iliac crest, and overlying the greater trochanter of the femur, or “thigh bone”. In adults, three of the bones of the pelvis have fused into the hip bone or acetabulum which forms part of the hip region.

Can laterally flex neck?

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.

Where are hip flexors?

The hip flexors are a group of muscles toward the front of the hip. They help you move or flex your leg and knee up towards your body. A hip flexor strain occurs when one or more of the hip flexor muscles becomes stretched or torn.

Where is the sternocleidomastoid quizlet?

The sternocleidomastoid muscle is a two-headed neck muscle, which true to its name bears attachments to the manubrium of sternum (sterno-), the clavicle (-cleido-), and the mastoid process of the temporal bone (-mastoid).

Where is the origin of the trapezius?

It originates on the occipital bone, the ligamentum nuchae, and the spinous processes of T01–T12. The trapezius inserts on the lateral third of the clavicle, as well as the acromion and scapular spine of the scapula.

Where are scalene muscles?

The scalene muscles are located deep in relation to the sternocleidomastoid muscle, lateral to the cervical spine, connecting the vertebrae to the first two ribs. The deep fascia or prevertebral fascia envelop the scalene muscles.

Where is the ligament?

Ligaments are bands of tough elastic tissue around your joints. They connect bone to bone, give your joints support, and limit their movement. You have ligaments around your knees, ankles, elbows, shoulders, and other joints.

Where is the posterior longitudinal ligament?

The posterior longitudinal ligament runs in the spinal canal attaching to the vertebral bodies and vertebral discs and tightens with cervical flexion.

What ligaments are in the back?

The three major ligaments of the spine are the ligamentum flavum, anterior longitudinal ligament (ALL), and posterior longitudinal ligament (PLL) (Fig. 7). The ALL and PLL are continuous bands that run from the top to the bottom of the spinal column along the vertebral bodies.

What plane is lateral flexion in?

The side-to-side bending of the spine is also a frontal plane movement, known as lateral flexion, which, for example, occurs during side bend exercises that work the obliques.

What are the 4 motions that can occur in the spine?

The principal movements permitted by the vertebral column are: flexion (bending forward), extension (bending backwards), lateral flexion (bending right/left), and rotation (torsion/twisting).

Which region usually moves first when bending forward?

According to Cailliet, the first part of bending forward consists of lumbosacral flexion followed by anterior tilting of pelvis at hip joints . The muscles in the lower back namely erector spinae, contract eccentrically to control the movement against gravity while trunk flexes and pelvis tilts anteriorly.

Is Downward Dog flexion or extension?

Downward-facing dog pose is an inverted arm support in which your spine is lengthened. Deepening the pose means moving your shoulder and hip joints towards flexion and your elbows and knees towards extension.

Is child’s pose flexion or extension?

While in Child’s Pose your hips are in flexion. Many of us have very tight hip muscles and don’t know how to release this area. Much of this is due to the predominance of sitting in our daily activities.

What is the another name of Parvatasana?

The common English name for parvatasana is mountain pose. Parvatasana comes from the Sanskrit words parvata, meaning “mountain,” and asana, meaning “pose.” In parvatasana, the body is thought to resemble the shape of a mountain.

The lumbosacral joint, also called lumbosacral symphysis, is an articulation between the fifth lumbar (L5) and first sacral (S1) vertebrae.

Where are secondary curvatures found?

Gradually secondary curves develop in the cervical and lumbar regions, Lordotic curves. These curves will continue to develop until growing stops. Spinal curves are either kyphotic or lordotic.

What is a lateral curvature of the spine?

Scoliosis is an abnormal lateral curvature of the spine. It is most often diagnosed in childhood or early adolescence. The spine’s normal curves occur at the cervical, thoracic and lumbar regions in the so-called “sagittal” plane.

What are the lateral projections on both sides of the vertebral arch?

Pedicles. Each vertebra has two cylinder-shaped projections (pedicles) of hard bone that stick out from the back part of the vertebral body, providing side protection for the spinal cord and nerves.

Which joints can laterally flex?

Flexion is the movement of a joint that increases the angle between the joint and the body part. Movement of a body part to the side is called lateral flexion. This type of movement is commonly associated with the neck and spine.

Which joint action occurs in the medial lateral axis?

also known as the Transverse Axis

As in the earlier elbow example, the axis projects from the medial side of the joint and extends out the lateral side. The position of the pin allows only forward and backward movement (flexion and extension) in the sagittal plane about this axis.
