There are 33 vertebrae in the spinal cord of a human being. They are broadly categorized into 5 areas. They are called the cervical, thoracic, lumbar, sacrum & coccyx vertebra. The upper 3 areas have a total of 24 vertebrae, which includes 7 cervical vertebrae, 12 thoracic vertebrae & 5 lumbar vertebrae. Sometimes the lumbar region, may have an additional vertebra, it does happen - but it is rare. 5 vertebrae are fused together to form the sacrum & 3 vertebrae form the end of the spinal column which is the coccyx.
Definition of lumbar vertebrae :
Are the five bones of the backbone that are situated between the thoracic vertebrae and the sacrum in the lower part of the back. They are the largest of the UNFUSED vertebrae and have stout processes for attachment of the strong muscles of the lower back.
The vertebral column is made up of 33 vertebrae in total. Humans have five sacral vertebrae in the sacrum, which is located at the base of the spine.

What is an anticlinal vertebra?
An anticlinal vertebra is a type of spinal vertebra with a unique feature where the spinal processes align horizontally rather than vertically. This horizontal alignment can lead to complications in the spine's flexibility and movement.
How many articulations are in the spinal vertebra?
There are four: one joint with the vertebra that is superior and one with the vertebra which is inferior plus superior and inferior processes (2) come off the pedicles. These articulate with the articular processes of the vertebrae above and below.
What is the function of the opening of the vertebra?
To allow passage of spinal nerves
What inferior boundary of the spinal cord is at the level of the vertebra?
The inferior boundary of the spinal cord typically ends at the level of the L1 or L2 vertebra in most adults.

How many disks on your spine?
