For example, the most superior cervical vertebrae is termed C1 and the most inferior C7, which is then followed by the T1 vertebrae of the thoracic region. The two lower most regions of vertebrae are the sacrum and the coccyx.
What is the most inferior region of the spine?
Anatomy & Physiology, Skeletal System, Vertebral Column and Hyoid Bone
|Coccygeal Region||The most inferior part of the vertebral column.|
|Lumbar Region (L1 – L5)||Region of the vertebral column formed by the five lumbar vertebrae (L1 – L5)|
What is the inferior part of the spinal cord?
At its inferior end, the spinal cord tapers to a point known as the conus medullaris and gives rise to many large nerve fibers known as the cauda equina. The cauda equina descends through the vertebral canal from the conus medullaris to the coccyx.
What are the 3 levels of the spine?
The spine has three normal curves: cervical, thoracic and lumbar. There are seven cervical vertebrae in the neck, 12 thoracic vertebrae in the torso and five lumbar vertebrae in the lower back.
What part of the spine controls the heart?
Thoracic (mid back) – the main function of the thoracic spine is to hold the rib cage and protect the heart and lungs. The twelve thoracic vertebrae are numbered T1 to T12.
What part of your spine controls your legs?
The nerves of the cervical spine go to the upper chest and arms. The nerves in your thoracic spine go to your chest and abdomen. The nerves of the lumbar spine then reach to your legs, bowel, and bladder. These nerves coordinate and control all the body’s organs and parts, and let you control your muscles.
What are the 4 types of vertebrae?
There are 33 vertebrae in the human spine that are split into four regions that correspond to the curvature of the spine; the cervical, thoracic, lumbar, sacrum, and coccyx.
What are the 3 main parts of a vertebra?
Cervical, Thoracic and Lumbar Spine
Each vertebra is made up of the vertebral body in the front, the facet joints in the back and the pedicles, which connect the vertebral body to the facet joints.
What part of spine is most prone to injury?
Understandably, the lumbar spine is the most commonly injured region of the spinal column. The lowest portion of the spine, the part that is connected to the pelvis, is called the sacrum.
