What are the smallest vertebrae?
cervical vertebrae
There are seven cervical vertebrae which are located in the neck. They are the smallest, and lightest vertebrae of the vertebral column.
Which is the largest vertebrae in the human body?
L5 has the largest body and transverse processes of all vertebrae. The anterior aspect of the body has a greater height compared to the posterior. This creates the lumbosacral angle between the lumbar region of the vertebrae and the sacrum.
How big is a human vertebrae?
Usually there are 7 cervical, 12 thoracic, 5 lumbar, 5 sacral and 4 caudal (coccygeal) vertebrae. In humans, the length of the vertebral column is 71 cm in males and 61 cm in females.
Why is the cervical vertebrae the smallest and most delicate?
The cervical vertebrae are the smallest and most delicate simply because they do not need to be larger and thicker.
Why are cervical vertebrae bifid?
The spinous process of a typical cervical vertebra is short and bifid posteriorly. It is bifid because it develops from two separate secondary centers of ossification. This morphology is unique to cervical spinous processes.
Where is your C4 and C5 vertebrae?
The C3, C4, and C5 vertebrae form the midsection of the cervical spine, near the base of the neck. A cervical vertebrae injury is the most severe of all spinal cord injuries because the higher up in the spine an injury occurs, the more damage that is caused to the central nervous system.
Which is the smallest of the lumbar vertebrae?
The L1 vertebra (1st lumbar vertebra) is the smallest and most superior of the lumbar vertebrae.
Which is the smallest bone in the human body?
The smallest and lightest bone in the human body is the stapes. This bone measures roughly 3 x 2.5 millimetres, which is greater along the head base span. The stape is a stirrup-shaped bone that is connected by an annular ligament to the oval window of the middle ear.
Where are the L1 and L2 vertebras located?
As the first vertebra in the lumbar region, the L1 vertebra bears the weight of the upper body and acts as a transition between the thoracic and lumbar vertebrae. The L1 vertebra is located in the spinal column of the lumbar (lower back) region inferior to the T12 vertebra and superior to the L2 vertebra.
Which is thicker the L1 or the vertebral arch?
The vertebral arch is a thin bony ring attached to the posterior of the vertebral body. In the L1 vertebra, it is a bit smaller than the vertebral body, but is much thicker and stronger than the arches of the cervical and thoracic vertebrae above it.
