What flexes the thoracic spine?
The thoracolumbar spine flexes (least amount of movement appears to be in the mid-thorax), the lumbar spine flexes and the pelvis anteriorly tilts (hips flex). Figure 3. Osteokinematic and arthrokinematic motion of the ribs and vertebrae of the typical thoracic rings 3–6 when the ring anteriorly tilts.
Where are the muscles that flex the spine?
TRUNK FLEXION About 75% of all spinal flexion below the neck occurs in the lumbar spine, and about 70% of all lumbar flexion occurs at the lumbosacral joint. Any muscle with vertical or oblique fibers that connects the thorax with the pelvis assists in flexion of the trunk.
Does the thoracic spine flex and extend?
Thoracic spine is considered to have a restricted range of motion (ROM) during flexion and extension compared with that of cervical and lumbar spine; ROM of thoracic spine is restricted by the rib cage. However, little is known about angular movements of thoracic spine.
What muscles flex and extend the spine?
These include the rotatores, multifidus, interspinalis and intertransversarius muscles. These act primarily as synergists for extension and rotation of the spine, as well as also acting as spine stabilizers. Trunk muscles also maintain the normal curvatures of the spine, and act as postural muscles.
What are the thoracic muscles?
The thoracic wall is made up of five muscles: the external intercostal muscles, internal intercostal muscles, innermost intercostal muscles, subcostalis, and transversus thoracis. These muscles are primarily responsible for changing the volume of the thoracic cavity during respiration.
What three muscles perform flexion at the vertebral column?
They include the longissimus, iliocostalis, and spinalis muscles. Their attachments subdivide these muscles, and they all have a common tendinous origin. They play a role in the movement of the thoracic cage and flexion of the upper vertebral column and head.
How much flexion is in the thoracic spine?
From neutral, the thoracic spine can flex to approximately 35 ° of additional flexion. Thus, in full flexion, the thoracic spine demonstrates up to 75 ° of flexion. Conversely, the thoracic spine only moves 20 ° to 25 ° of extension.
How do you keep your thoracic spine flexible?
Spiderman with Thoracic Spine Rotation Movement: Bring one foot up beside your hand, then rotate and reach for the ceiling with that same hand. Drop your hips slightly down towards the floor and hold this stretch for several seconds. Repeat on both sides.
What is thoracic spine extension?
Thoracic extension is the ability for the t-spine to move from its normally kyphotic or forward rounded position to a flat or event arched back position. Lack of thoracic extension is one of the most common mobility restrictions we see.
What is flexion and extension of the spine?
Flexing your muscles usually results in bringing the bones attached closer together. For example, the spine is in flexion when we bend forwards. Extension is simply the opposite, increasing the angel between parts, e.g. bending backwards. The spine is made up of 33 bones.
Which of the following muscles allows for flexion and rotation of the spine?
The intermediate layer contains the erector spinae muscles, whose many functions include the extension and lateral flexion of the spine, head and neck. The deep layer consists of the transversospinalis muscles. Their functions include extension, lateral flexion and rotation of the head and spine.
What is flexion of the spine?

Iliocostalis Lumborum. Extension, lateral flexion of vertebral column, rib rotation. Dorsal primary divisions of spinal nerves. Muscle Fascia. Fascia is thickened connective tissue that envelops a muscle or a group of muscles. Superficial fascia is found directly under the skin.
What are the functions of muscles?
Muscles are named according to their shape, location, or a combination. They are further categorized according function such as flexion, extension, or rotation. Muscles and ligaments work together to support the spine, hold it upright, and control movement during rest and activity. Skeletal muscle is striated (striped) in appearance.
What is the energy needed for muscle contraction?
Energy is needed for the muscle to contract (work). Mitochondria (cellular level) produce ATP (adenosine triphosphate), a chemical cells need for energy. ATP is produced as the mitochondria burn glucose (sugar). Blood vessels deliver the oxygen and nutrients the mitochondria needs to provide a steady supply of ATP. 1.
What muscles are involved in the thoracic spine?
The muscles that affect the thoracic spine’s function include: 1 Spinalis: This long muscle moves the spine and helps with posture. Ligaments of this muscle attach to multiple thoracic vertebrae. Although narrow at its ends, at the top of the first thoracic vertebra and within the lumbar spine, the spinalis is wide in the middle. 2 Longissimus: Another long muscle, this one travels up the spine from the middle of the lumbar spine. It runs on both sides of the spinalis.

What is the thoracic spine?
The spine in the upper back and abdomen is known as the thoracic spine. It is one of the three major sections of the spinal column. The thoracic spine sits between the cervical spine in the neck and the lumbar spine in the lower back. Collectively, these three sections make a tower of 24 bones that gives the body structure and houses ...
What is the function of the spinal cord?
The spinal cord and its nerves facilitate communication between the body and the brain. Together, the brain and spinal cord make up the central nervous system. Other than protecting the spinal cord, the vertebrae create joints that allow the spine to bend and twist.
Why is the thoracic spine unique?
The thoracic spine is unique in relation to other segments of the spine because pairs of rib bones extend from the spaces between its 12 vertebrae. The ribs’ curved shapes create a cage-like structure that houses and protects many vital organs, including the heart and lungs.
What is a herniated disc?
Herniated disc, or damage to the cushioning pad between vertebrae. Infection of the spinal cord, fluid, or discs. Osteoarthritis, a degenerative bone disease. Spondylolisthesis, a severe form of degenerative disc disease. Last medically reviewed on January 19, 2018.
Why does my back hurt so bad?
Because the thoracic spine is used so much in daily life, it is prone to strain and injury for many reasons, from improper posture to compression fracture. Some injuries can put pressure on the spinal nerves, creating even stronger pain and other symptoms. Some causes of recurring back pain include:
What is the normal kyphotic curve of the thoracic spine?
A healthy thoracic spine should have a natural kyphotic curve that measures approximately 40 degrees ( Figure 1 A ). Although it is possible for this curve to be abnormally decreased, in other words, hypokyphotic (Figure 1B ); by far the more common postural distortional pattern is for the thoracic spine to become hyperkyphotic ( Figure 1C ). In lay terms, this is often described as rounded back.

Does UCS cause thoracic outlet syndrome?
And if this were not enough, UCS also increases the likelihood of all three myofascial forms of thoracic outlet syndrome: pectoralis minor syndrome, costoclavicular syndrome, and anterior scalene syndrome. Pectoralis minor syndrome due to the locked-short pectoralis minor; costoclavicular syndrome due to the collapsed posture of the clavicle against the first rib; and anterior scalene syndrome due to the adaptive shortening of the scalene musculature.
What is the thoracic spine?
The thoracic spine is one of the four major regions of the spine. Watch: Spine Anatomy Overview Video.

How many vertebrae are in the thoracic spine?
The thoracic spine has 12 vertebrae stacked on top of each other, labeled from T1 down to T12. These vertebrae form the foundation of the thoracic region’s sturdy spinal column that supports the neck above, the rib cage, soft tissues, flexible joints, blood vessels, and nerves.
What causes upper back pain?
Upper back pain is typically due to one of the following: 1 Muscular problems. Upper back pain is most commonly caused by muscle irritation or tension, also called myofascial pain. The cause may be poor posture (such as forward head posture) or any type of irritation of the large back and shoulder muscles, including muscle strain or spasms. 2 Joint dysfunction. Thoracic spinal joints can become painful in various ways. For example, cartilage tears and degeneration can develop in the facet joints where adjacent thoracic vertebrae articulate with each other. It is also possible for a rib to become misaligned or displaced from the vertebrae. In many cases, facet joint degeneration (osteoarthritis) and degenerative disc disease can happen at the same time.
What is the spinal cord?
Protect the spinal cord. The spinal cord is a critical bundle of nerves that sends electrical signals throughout the body. It runs from the base of the brain down through the bony vertebral canal of the cervical spine and thoracic spine before branching into smaller nerve bundles in the lumbar spine. See Spinal Cord and Spinal Nerve Roots.
Which spine supports the heart and lungs?
See Spinal Cord and Spinal Nerve Roots. Anchor the rib cage. The rib cage, supported by the thoracic spine in the back, forms a bony structure to surround and protect vital organs, such as the heart and lungs.
