What is the uppermost vertebrae called as?
The uppermost vertebrae is called the atlas. It is the first cervical vertebra located at the top of the spine, just below the skull. It is named after the Greek Titan Atlas, who held up the celestial spheres.
What is a sacral vertebra?
A sacral vertebra is one of the bones in the spine located in the lower back, just below the lumbar vertebrae. There are typically five sacral vertebrae that are fused together to form the sacrum, which connects the spine to the hip bones. The sacral vertebrae play a role in supporting the weight of the body and protecting the spinal cord.
How is your skull attached to your spine?
There is a bone at the lower and posterior part of the skull called the occipital bone, which, along with the atlas and the axis (the topmost vertebrae) forms the joint connecting the skull and spine. Answer provided by Migue Antonio.-
Which one is the first vertebra of vertebral column?
The first vertebra of the vertebral column is called the atlas. It is named after the Greek titan Atlas who was said to carry the weight of the world on his shoulders, as the atlas supports the weight of the skull.
What are the small bones called that make up the spine?
This is a tricky question as it is not clear which end of the spine we are referring to. At the head end there is a bone or vertebra upon which the head is resting this is known as the atlas, it does not have a body and its centrum fuses with the axis to provide a pivot for the head to turn on. At the other end of the spine - the tail end the last bones are fused together to form the coccyx, the number may vary from 3 to 5. These bones are rudimanetary and are usually fused together.
Where is the axis located in your body it sits on a bone?
The axis is the second cervical vertebra in the spine, located just below the atlas (the first cervical vertebra). It is named after its function as it allows the head to rotate on top of the spine.
Lump in the middle of the top of the back of your neck and it pops out when you look down what could this be?
That would most likely be the top ridge of one of your vertebra in your spine.
What is the first bone of the cervical column?
The vertebrae are the backbones. The cervical vertebrae are at the top. The skull rests on and turns on the first cervical vertebra, called "C1". C1 is tied to the second cervical vertebra, called "C2", which allows, the head to turn far to each side by a special arrangement of bone and ligaments. C3, C4, and C5 are regular vertebrae, but smaller than those further down the spine.
What is the medical term meaning lumbar?
"Lumbar" refers to the region of the back or spine made up of the lumbar vertebrae. The 1st lumbar vertebra is just under the 12th thoracic vertebra. The easiest way to find this is to find the first vertebral body not connected to a rib. This is L1 (1st lumbar vertebra). There are 5 lumbar vertebrae (L1 through L5). The 5th lumbar vertebra sits on top of the sacrum (where your spine connects with your pelvis).
What is L5 - S1 located?
They are the names of specific vertebrae in the spine. The anatomy of the spine is sectioned for better identification and specificity. There is the neck area, the cervical spine; the main upper part of the back is the thoracic spine; the area at the "small of the back" is the lumbar spine; the part below that is the Sacral spine (also called the sacrum) which is five fused together vertebrae; and then finally the tailbone is called the coccyx and is actually four fused vertebrae. Each of the vertebra in a section is numbered. There are normally 33 vertebrae in humans (counting the fused ones). There are 7 in the cervical area, 12 in the thoracic area, 5 in the lumbar area, and the 9 making up the sacrum and coccyx. So L5 is the fifth Lumbar vertebra (counting from the top down). It is also the most common vertebra involved in lumbar disorders and low back pain. It is the last of the lumbar vertebrae. L4 is in the general area of the waist or at the highest point of the pelvic bones. So just down from there is L5 and S1 is the next one down.
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.
What is lumber in the human body?
The lumbar spine is the lower back that begins below the last thoracic vertebra (T12) and ends at the top of the sacral spine, or sacrum (S1). Most people have 5 lumbar levels (L1-L5), although it is not unusual to have 6. Each lumbar spinal level is numbered from top to bottom—L1 through L5, or L6.13-
What is the peg bone at the top of the spine?
it is called the odontoid
What does a Desiccation in the L5 S1 mean?
The spine has several sections, each denoted by a letter. Starting from the top, C=cervical spine (neck); T=thoracic spine (upper body); L=lumbar spine (lower body); and S=sacral or sacrum (just above the talbone). (There is also the coccyx, or tailbone, which in most is one solid bone, and has no specific letter denotation.) Each section has multiple bones called vertebrae that are numbered. There are spaces in between each vertebra called discs. These are circular pieces of cartilage filled with a jelly-like material called the nucleosus pulposus. These discs serve as a cushion between the bones, and are crucial to allowing the spine to flex and bend freely. Discs are named by using the position of the vertebrae that "sandwich" it, in this case, L5,S1 (the 5th lumbar vertebra and 1st sacral vertebra). Dessication means drying out. So, in layman's terms, the disc in the lowest part of the lumbar spine has dried out, which means that the it is less able to provide cushioning from the bones during movement.
What is the junction?
It's the place where the bottom-most lumbar vertebra meets the top of the sacrum.
What is the T2 and where is it located?
Your spine is composed of 5 sections from top to bottom: cervical, thoracic, lumbar, sacral, & coccygeal.The thoracic section starts at the bottom of your neck and ends at the top of your low back. The thoracic section contains 12 vertebrae (or bones). The second thoracic vertebrae from the top is called the T2 vertebra. This level is located near the top of where your shoulder blades are.
What does vertebrea mean?
"Vertebra" refers to the individual bones that make up the vertebral column, or spine, in vertebrate animals. Each vertebra has a central hole through which the spinal cord passes, and they are stacked on top of one another to form the spine, providing structural support and protecting the spinal cord. The term is often used in the context of anatomy and biology to describe the segments of the backbone.
