The weight bearing portion is the bodyof the vertebra. It is shaped like a box which is excellent for resisting load longitudinally like sitting or standing or for more powerful activities such as running or swinging a golf club. The articular processes are the movement portion of the vertebra..
Besides, which vertebrae are weight bearing?
Lumbar (low back) - the main function of the lumbar spine is to bear the weight of the body. The five lumbar vertebrae are numbered L1 to L5.
Also, what are the 3 main parts of a vertebra? The normal anatomy of the spine is usually described by dividing up the spine into three major sections: the cervical, the thoracic, and the lumbar spine. (Below the lumbar spine is a bone called the sacrum, which is part of the pelvis). Each section is made up of individual bones, called vertebrae.
In this way, which part of a vertebra bears the most weight?
The body is the largest part of the vertebrae and the part that bears the most weight. The lamina is the lining of the hole (spinal canal) through which the spinal cord runs.
Which region of the spine is the main load bearing area?
Lumbar

What part of the spine controls the legs?
The thoracic vertebrae are situated between the cervical (neck) vertebrae and the lumbar vertebrae. These thoracic vertebrae provide attachment for the ribs and make up part of the back of the thorax or chest. Damage or SCI's above the T1 vertebra affects the arms and the legs.What nerves are affected by t12?
At T12, the ventral ramus becomes a subcostal nerve that travels beneath the twelfth rib. At T1 through T12, the dorsal ramus goes into the back muscles and also provides sensation to the skin. The motor and sensory functions provided by a thoracic nerve root are determined by its vertebral level.What nerves are affected by c1 and c2?
C1, C2, and C3 (the first three cervical nerves) help control the head and neck, including movements forward, backward, and to the sides. The C2 dermatome handles sensation for the upper part of the head, and the C3 dermatome covers the side of the face and back of the head.What are the 31 pairs of spinal nerves and their functions?
Spinal nerve, in vertebrates, any one of many paired peripheral nerves that arise from the spinal cord. In humans there are 31 pairs: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal. Each pair connects the spinal cord with a specific region of the body.Where is the t12 located in the spine?
Each of the vertebrae in the spinal column has a specific shape which is designed to protect the spinal cord from injury. The T12 vertebra is located in the last position of the thoracic section of the spine, and sits just above the lumbar section.Is the spine a weight bearing joint?
The joints of the body that hold us up when we stand and carry the mass of our body are called “weight bearing joints.” The primary weight bearing joints are the ankles, knees and hips. Joints of the feet, pelvis and low back and spine (especially the low back) are also weight-bearing.Where is the t11 vertebra located?
The eleventh thoracic vertebra (T11) is located near the bottom of the thoracic spine. Generally, the spinal bones are larger and heavier the further down they are located.Where is the 6th vertebrae located?
The C6 vertebra is the sixth cervical vertebra of the spine. It is found in the base of the neck between the C5 and the last cervical vertebra, C7.What is the only bone in your head that can move?
Your lower jawbone is the only bone in your head you can move. It opens and closes to let you talk and chew food. Your skull is pretty cool, but it's changed since you were a baby. All babies are born with spaces between the bones in their skulls.How long is the human tailbone?
The coccyx is a small, triangular bone measuring less than one inch (2.5 cm) in length and curved like a hawk's beak. It is widest at its superior border, where it meets the sacrum, and is narrowest at its inferior tip.Where is t1 and t2 located?
The second thoracic vertebra, or T2, is located directly below the first thoracic vertebra (T1). It is slightly larger than the T1, but smaller than the third thoracic vertebrae (T3). The second thoracic vertebra contains faceted sides that allow the vertebra to press up against the ribs.Where is the l4 & 5 in the spine?
The L4 and L5 are the two lowest vertebrae of the lumbar spine. Together with the intervertebral disc, joints, nerves, and soft tissues, the L4-L5 spinal motion segment provides a variety of functions, including supporting the upper body and allowing trunk motion in multiple directions.Do all humans have the same number of vertebrae?
Most people have the same number of vertebrae. The typical number is seven cervical, 12 thoracic and 5 lumbar vertebrae. There are also sacral vertebra analogues which are all typically fused to form the sacrum.Where is the base of the spine located?
The sacrum forms the base of the spine and the back of the pelvis. Below the sacrum is a small bone called the coccyx (or tailbone), which is another specialized bone created by the fusion of several smaller bones during development.Why are the vertebrae different sizes and shapes?
The size and shape of each lumbar vertebra is designed to carry most of the body's weight. Each structural element of a lumbar vertebra is bigger, wider and broader than similar components in the cervical and thoracic regions.What does a normal back look like?
The normal curvature of the spine looks like this: The spine in your neck (cervical spine) has a slight inward curve called a lordotic curve. The upper-to-mid back (thoracic spine) curves outward slightly in what's called a kyphotic curve. The lower back (lumbar spine) also has a slight inward lordotic curve.What is typical vertebra?
A typical vertebra consists of (1) a body and (2) a vertebral arch, which has several processes (articular, transverse, and spinous) for articular and muscular attachments. The bodies of the vertebrae are separated from each other by intervertebral discs.What is the lower part of your back called?
The lower back, which starts below the ribcage, is called the lumbar region.What are the backbones called?
The spinal column, better known as your backbone, is a strong yet flexible multipurpose structure. At the bottom of the spinal column are the remaining bones, the naturally fused vertebrae of the sacrum and coccyx, which join with your pelvis (hip bones).
