What is T10 responsible for?
T10 innervates the muscles of the lower abdomen. It is part of the section of the spinal cord which is most vulnerable to injury due to the area's high level of flexibility. An injury in this area will most likely experience limited or complete loss of use of the muscles in the lower abdomen, buttocks, legs, and feet.
What nerve comes out at T10?

Where is T10 on your back?
The T10 Vertebra, also called the tenth thoracic vertebra, is a part of your thoracic spine and the tenth down from the top. It's in the lower part of your mid-back and is one of the vertebrae that attaches to your rib cage in your mid-back.
What is a t10 compression fracture?
Compression fractures are small breaks or cracks in the vertebrae (the bones that make up your spinal column). The breaks happen in the vertebral body, which is the thick, rounded part on the front of each vertebra. Fractures in the bone cause the spine to weaken and collapse. Over time, these fractures affect posture.

What is a t10 compression fracture?
Compression fractures are small breaks or cracks in the vertebrae (the bones that make up your spinal column). The breaks happen in the vertebral body, which is the thick, rounded part on the front of each vertebra. Fractures in the bone cause the spine to weaken and collapse. Over time, these fractures affect posture.

Why do thoracic vertebrae fracture?
Thoracic Vertebrae Fractures. Thoracic vertebrae fractures are usually due to accidents with hard falls and physical trauma, or conditions such as osteoporosis. This injury occurs when the vertebrae spine collapses in its weakened state due to pressure.
What is the eleventh thoracic vertebra?
The eleventh thoracic vertebra (T11) is one of the last thoracic spinal vertebrae. It’s the first of the transitional vertebra that is not attached to a true rib, meaning a rib bone that connects to the chest’s sternum.
Why are T9 and T12 considered transitional vertebrae?
Sections T9 - T12 are known as transitional vertebrae because of their proximity and similarity to the lumbar vertebrae. The spinal cord and nerves’ correlation to these levels, along with the rest of the thoracic spine, aid in controlling the trunk of the body. The completeness of the spinal cord damage will determine how severe an injury truly is ...
What are the symptoms of a T11 injury?
A T11 injury will demonstrate itself by severe back and leg pain. If the nerves in the T11 vertebrae are damaged, common symptoms include weakness and numbness in these areas.
What is the body of a thoracic vertebra?
The body of a thoracic vertebra is somewhat “heart-shaped,” and is larger than the cervical but smaller than the lumbar vertebrae in size. The body also has small, smooth, and somewhat concave costal facets for the attachment of the ribs. Ribs are generally inserted between two vertebrae, such that each vertebra contributes to articulating with half of the articular surface. Each vertebra therefore has a pair of superior articular facets that face posteriorly and a pair of inferior articulating facets that face anteriorly (except for T12). This means that the rib will articulate with the inferior costal facet of the upper vertebrae and the superior costal facet of the lower vertebrae. Transverse processes arise from the arch found behind he superior articular processes and pedicles, and are thick and strong with a clubbed end and a small concave surface for the articulation with the tubercle of a rib. These processes are directed obliquely backward towards the spinous process and lateralward.
Which vertebrae are the spinous process?
First thoracic vertebrae (T1): Has on either side of the body, an entire articular fact for the head of the first rib, and a demi-facet for the upper half of the head of the second rib. The spinous process is thick, long, and almost horizontal. The transverse processes are long, with the upper vertebral notches deeper than any of those found on the other thoracic vertebra e. The thoracic spinal nerve 1 passes through underneath T1.

Last reviewed: May 31, 2021. Reading time: 15 minutes. The twelve thoracic vertebrae are strong bones that are located in the middle of the vertebral column, sandwhiched between the cervical ones above and the lumbar vertebrae below. Like typical vertebrae, they are separated by intervertebral discs. However, they are various anatomical features ...
What is the difference between vertebrae and vertebrae?
The vertebrae are separated by intervertebral discs of fibrocartilage, which are flexible cartilage discs located between the bodies of two adjacent vertebrae that allow movement in the spine and have a shock absorbing or cushioning function as well. An intervertebral disc consists of an inner gelatinous nucleus pulposus surrounded by a ring of fibrocartilage, the annulus fibrosus.
Why do thoracic vertebrae increase in size?
Thoracic vertebrae increase in size as they descend towards the lumbar vertebrae; this is because the lower vertebrae must be able to support more of the body’s weight when a person is standing due to the effects of gravity. To summarize, the main anatomical components of a thoracic vertebra are: Body. Spinous process.
What is the ribs of a vertebra?
Ribs are generally inserted between two vertebrae, such that each vertebra contributes to articulating with half of the articular surface. Each vertebra therefore has a pair of superior articular facets that face posteriorly and a pair of inferior articulating facets that face anteriorly (except for T12).
What do T3 and T4 feed into?
T3, T4, and T5 feed into the chest wall and aid in breathing. T6, T7, and T8 can feed into the chest and/or down into the abdomen. T9, T10, T11, and T12 can feed into the abdomen and/or lower in the back. 1.
How many nerve roots are there in the thoracic spine?
Thoracic Spinal Nerves. The thoracic spine has 12 nerve roots (T1 to T12) on each side of the spine that branch from the spinal cord and control motor and sensory signals mostly for the upper back, chest, and abdomen. The thoracic spine (highlighted) spans the upper and mid-back. It includes twelve vertebrae named T1 through T12.
How many thoracic nerves are there?
Each thoracic spinal nerve is named for the vertebra above it. For example, the T3 nerve root runs between the T3 vertebra and T4 vertebra. There are 12 thoracic spinal nerve root pairs (two at each thoracic vertebral level), starting at vertebral level T1-T2 and going down to T12-L1.
What nerves feed into the ventral ramus?
After branching from the spinal cord and traveling through the foramen, a thoracic nerve root branches into two different nerve bundles that feed into the nerves at the front (ventral ramus) and back (dorsal ramus) of the body. At the T1 through T11 levels, the ventral ramus eventually becomes an intercostal nerve that travels along ...
What is spinal cord injury?
Spinal cord injuries are usually classified based on the spinal nerve root level where function is reduced or completely lost. For example, a T6 spinal cord injury would impair or lose function at the T6 nerve root level and below.
What nerve travels between the ribs?
At the T1 through T11 levels, the ventral ramus eventually becomes an intercostal nerve that travels along the same path as the ribs (specifically between the innermost and internal intercostal muscles that connect adjacent ribs). At T12, the ventral ramus becomes a subcostal nerve that travels beneath the twelfth rib.
What is the hole in the spinal canal called?
Each thoracic nerve root exits the spinal canal through a bony hole, called an intervertebral foramen. This bony hole is formed by two adjacent vertebrae, and its size and shape can slightly shift as the vertebrae move.

What is the term for the nerves that connect the spinal cord?
Spinal nerves are referred to as “mixed nerves.”. The meningeal branches (recurrent meningeal or sinuvertebral nerves) branch from the spinal nerve and re-enter the intervertebral foramen to serve the ligaments, dura, blood vessels, intervertebral discs, facet joints, and periosteum of the vertebrae. Actions of the Thoracic spinal Nerves.
