Where are the 12 thoracic vertebrae located?
Where are the 12 thoracic vertebrae located?
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.
Which region contains 12 vertebrae?
thoracic region
The thoracic region contains 12 vertebrae, denoted T1-T12.
Which vertebrae are found in the chest region of the body?
The thoracic vertebrae are located in the thorax posterior and medial to the ribs. They form the region of the spinal column inferior to the cervical vertebrae of the neck and superior to the lumbar vertebrae of the lower back. Continue Scrolling To Read More Below…
What are the 12 vertebrae in the chest called?
The spine above the sacrum consists of: Seven bones in the neck—the cervical spine. 12 bones in the chest—the thoracic spine.
Where are the thoracic vertebrae located in the back?
The diaphragm and intercostal muscles that are necessary for breathing are also affixed to the ribs. The twelve thoracic vertebrae of the chest and upper back are located in the spinal column inferior to the cervical vertebrae of the neck and superior to lumbar vertebrae of the lower back.
How is the twelfth thoracic vertebra different from the eleventh?
Twelfth thoracic vertebra (T12) The twelfth thoracic vertebra has the same general characteristics as the eleventh, but may be distinguished from it by its inferior articular surfaces being convex and directed lateralward, like those of the lumbar vertebrae; by the general form of the body, laminae, and spinous process,…
Is the sternum part of the thoracic cage?
The thoracic cage surrounds and protects the heart and lungs in the thoracic cavity. It consists of the ribs, the sternum, and the thoracic vertebrae, to which the ribs articulate. We examined the thoracic vertebrae last lab, so here we will only examine the ribs and sternum. There are twelve pairs of ribs.
What are the articular facets of the thoracic vertebrae?
The positioning of the ribs and spinous processes greatly limits flexion and extension of the thoracic vertebrae. Thoracic vertebrae have superior articular facets that face in a posterolateral direction. The spinous process is long, relative to other regions, and is directed posteroinferiorly.
How many pairs of thoracic vertebrae are there?
We examined the thoracic vertebrae last lab, so here we will only examine the ribs and sternum. There are twelve pairs of ribs. The number is the same in both males and females. Each pair articulates with a different thoracic vertebra on the posterior side of the body.
Which is the most upright part of the thoracic spine?
The spinal column is the body’s main upright support. The middle 12 Thoracic vertebrae make up the thoracic spine. T5-T8 tend to be the most “typical” in that they contain features present in all thoracic vertebrae. T5-T8 have the greatest rotation ability of the thoracic region. T1 – superior costal facets are “whole” costal facets.
How are the ribs connected to the thoracic vertebrae?
The most superior rib is designated rib 1 and it articulates with the T1 thoracic vertebrae. The rib below that is rib 2, and it connects to the T2 thoracic vertebra, and so on. Ten of the twelve ribs connect to strips of hyaline cartilage on the anterior side of the body.
