Where is the pedicle located?
The pedicle is a short projection of bone that comes directly off the back of the vertebral body. The pedicle lies between the back of the vertebral body and the transverse process. There are two pedicles per vertebra, one on each side.
What is mammillary process of lumbar vertebra?
The mammillary processes provide a point of attachment for intertransversarii muscles and multifidus. The curvature of articular facets is thought to assist in the stabilization and weight-bearing capacity of the lumbar vertebrae.
What are the 33 vertebrae?
Vertebral Column and Spinal Cord The vertebral column (VC) is composed of 33 vertebrae [cervical (C), 7; thoracic (T), 5; lumbar (L), 5; sacral (S), 5; coccygeal, 4], which are interconnected by intervertebral (IV) disks (except C1, C2) and stabilized by spinal ligaments.
What are the top 7 vertebrae called?
Regions of the Spine Cervical (neck)- the top seven vertebrae /bones are called C1-C7. Thoracic ( upper back)- the next 12 vertebrae /bones are called T1-T12. Lumbar (lower back)- the next five vertebrae /bones are called L1-L5.
What does the pedicle do?
Pedicles. Each vertebra has two cylinder-shaped projections ( pedicles ) of hard bone that stick out from the back part of the vertebral body, providing side protection for the spinal cord and nerves. The pedicles also serve as a bridge, joining the front and back parts of the vertebra.
What is your Lamina?
The lamina is the flattened or arched part of the vertebral arch, forming the roof of the spinal canal; the posterior part of the spinal ring that covers the spinal cord or nerves.
What is the functional reason for bigger and stronger lumbar vertebrae?
The vertebrae in the lumbar spine area are the largest of the entire spine, so the lumbar spinal canal is larger than in the cervical or thoracic parts of the spine. Because of its size, the lumbar spine has more space for the nerves to move about.
What is the lumbar vertebrae function?
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. These vertebrae are much larger in size to absorb the stress of lifting and carrying heavy objects.
Why is the lumbar vertebrae the largest?
There are 5 lumbar vertebrae (denoted as L1-L5) found in adult humans, and they are situated beneath the thoracic vertebrae, They are the largest, in terms of size, out of all the vertebrae because the lumbar vertebrae must be able to support the weight of the body when a person is standing due to the effects of
How many vertebrae are in the human body?
The average person is born with 33 individual bones (the vertebrae ) that interact and connect with each other through flexible joints called facets. By the time a person becomes an adult most have only 24 vertebrae because some vertebrae at the bottom end of the spine fuse together during normal growth and development.
How many spinal cords are in the human body?
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. Near the spinal cord each spinal nerve branches into two roots.
What are the names of the 26 vertebrae?
These regions are called the cervical spine, thoracic spine, lumbar spine, sacrum, and coccyx.
Which vertebrae is the strongest?
Some people have 6 lumbar vertebrae. These vertebrae are your largest and strongest vertebrae, responsible for carrying a lot of your body’s weight. The lumbar vertebrae are also your last “true” vertebrae; beneath this region, your vertebrae are fused by the time you stop growing.
Which is the largest vertebrae in the human body?
Lumbar Vertebrae. There are five lumbar vertebrae in most humans, which are the largest in the vertebral column. They are structurally specialised to support the weight of the torso. Lumbar vertebrae have very large vertebral bodies, which are kidney shaped.
What is the name of the top vertebrae in your spine?
The Atlas: The Top Bone in Your Cervical Spine The atlas is also known as C1, and while other bones in your spine are numbered in such a way (eg, the first bone is your lumbar spine is known as L1), this vertebra is much different in shape and function compared to the rest of your vertebrae.
