What massive vertebra is weight-sustaining?
There are five lumbar vertebrae located in the lower back. These vertebrae receive the most stress and are the weight-bearing portion of the back. The lumbar vertebrae allow movements such as flexion and extension, and some lateral flexion. Thoracic vertebra Final Answer: lumbar vertebra
The longest segment of the vertebral column?
You tend to think about the sacrum. But it is not the case. You have the tail bone or the coccyx. It is the most inferior bone in the vertebral column.
Which area of the spine has the most vertebrae?
The thoracic spine has the most vertebrae - twelve.
Which type of vertebrae takes up the most space on a human's spine?
The thoracic vertebrae take up the most space on a human spine.
What part of the vertebral column receives the most stress by bearing most of the weight of the body?
The lumbar vertebrae in the abdoninal region The segment, or group, of vertebrae that bear the most weight in the body is at the lumbosacral joint between lumbar vertebra number five (L5) and the sacrum.
Total thoracic vertebrae do animals have?
It depends on the animal. The thoracic vertebrae are those of the "chest" and attach to the ribs. In the dog and cow for instance, there are 12 (same number as the ribs) but there are 18 in the horse (also the same number as the ribs).
How many thoracic vertebrae are in the vertebral column?
There are a pair of 12 of thoracic vertebrae in the human body. Some variations exist, as in all of nature, but that is most commonly agreed upon number. The vertebrae of the spine are divided into sections (cervical, thoracic, lumbar, sacral and the coccyx). The thoracic 3 and 4 vertebrae control much of the upper back kyphotic curve. There are special areas called dermatomes in our bodies where our spinal nerves can affect certain areas associated with them; skin, muscles, joints, and organs. There are 12 thoracic vertebra in human skleletalTwelve.The adult body has 7 cervical vertebra, 12 thoracic vertebrae, and 5 lumbar vertebrae. It can be remembered as: breakfast at 7am, lunch at 12noon, and dinner at 5pm.There are 12 thoracic vertebrae.12, they are labeled T1 to T12
How many vertebrae are there in each of the three superior region of the vertebral column?
Cervical (most superior portion of the vertebral column) = 7 vertebraeThoracic (just inferior to the cervical region, superior to lumbar) = 12 vertebraeLumbar (inferior to the thoracic region, superior to the sacral region) = 5 vertebrae
What is the bone in the backbone?
The bones of the back are the vertebrae, doughnut-shaped bones with the spinal nerves running through them and spongy cartilage discs between most of them. In humans, the spine consists of 33 vertebrae divided into five groups: the cervical vertebrae (neck), thoracic vertebrae (ribs), the lumbar vertebrae (back), the sacral vertebrae (hips) and the coccygeal vertebrae (coccyx or tailbone).
What are the four sections of the spine?
In human anatomy the spinal column has been divided into four sections for reference and specificity; the cervical spine, the thoracic spine, the lumbar spine and the sacral spine. The Cervical Spine is the section in the neck area comprised of seven vertebrae starting at the base of the skull and counting down the spine. To refer to the individual vertebrae in that area you would again start at the base of the skull with C1, and then count down to the last cervical vetebra, C7. The cervical spine is made up of C1, C2, C3, C4, C5, C6, and C7. The Thoracic Spine is the next section down the back located in the chest area and is comprised of twelve vetebrae. The ribs connect to the thoracic spine and create a strong skeletal structure that protects the vital organs. The vertebrae in the thoracic spine start with the eighth vertebra down which is called T1 and continued through T12. The third major region of the spine, the Lumbar Spine,starts below the thoracic spine with the thirteenth vertebra, L1, and continues through L5 for most people, although it is not uncommon for some people to have a sixth Lumbar verterbra, L6. When you have a low backache, it is usually in the area of the Lumbar Spine since it is the part of the vertebral column that supports most of the body's weight. The final section of the spine continues from the last lumbar vertebra, number seventeen (or eighteen, if there are six in this section) and down to the pelvis. This is called the Sacral Spine and has only one vertebra, the sacrum, called S1, and the coccyx bone which is also known as the tail bone. The sacrum and coccyx are uniquely shaped.
Where are compression fractures most common?
Compression fractures are most common along the spine involving the vertebrae. This is when a bone in the spine collapses and is most commonly found in the thoracic area of the spine.
How many vertebra fuse to form the sacrum?
You have 7 unfused cervical vertebrae. You have 12 unfused thoracic vertebrae. You have 5 unfused lumber vertebrae. The five vetebrae are fused in case of the sacrum. That is the need of the hour. You can not support the hip bones with out that fusion. Then there are few fused vertebrae in coccyx.
