What is the function of the body of vertebrae and the bony plates and projections found behind?
Support the weight of everything that is above
Protect the spinal cord
Give attachment to muscles and ligaments
To articulate with the adjoining vertebrae
What is the part of the vertebrae that encloses the spinal cord?
The neural arch
What is the space surrounded by the neural arch called and what’s its purpose?
The vertebral foramen which when in a series, contains the spinal cord in a vertebral canal
What is the part of the vertebrae that provides support and protection for the backside of the spinal cord?
The lamina
What is the function of the pedicle?
Provides support to the posterior wall when constrained through the posterior arch
How do the spinal nerves come out of the spinal cord?
Intravertebral foramens
Features of the cervical vertebrae.
Small Body
Upper surface of the body is curved in the shape of a saddle
Lower surface of the body is the same but reversed
The vertebral foramen is large and triangular
The neural arch is formed by mainly the 2 STRAIGHT laminae
The pedicles are very short
The spinous process is short and ends in a double point
The upper articular facets face upwards and inwards
The lower articular facets face downwards and forwards
