Types of Vertebra

Question 1

What are the main types of Vertebra in the spine?

Answer 1

Cervical, Thoracic and Lumbar.

Question 2

What does the Cervical Vertebra consist of?

Answer 2

The smallest of all the vertebra, The spinous processes are slender.

Question 3

What does the Thoracic Vertebral consist of?

Answer 3

Larger than the Cervical vertebra, The spinous processes are long fairly thick and most project inferiorly.

Question 4

What does the Lumbar Vertebra consist of?

Answer 4

These are the largest and thickest of all the vertebra. The spinous processes are short blunt and project posteriorly rather than inferiorly.

Question 5

What are the Axial and the Atlas in the Spine?

Answer 5

These are the two most superior bones/vertebra in the spine. Atlas = C1, Asix = C2.

Question 6

Where does the spinous fossa protrude from in the body for most of the vetebra?

Answer 6

The Cervical and lumbar vertebra protrude posteriorly out the back of the body while the most of the thoracic protrude inferiorly.

Question 7

Where does the spinous fossa protrude from in the body for most of the vetebra?

Answer 7

The Cervical and lumbar vertebra protrude posteriorly out the back of the body while the most of the thoracic protrude inferiorly.

Question 8

What are the 2 lowest types of bones in the vertebra column?

Answer 8

This includes the Sacrum and Coccyx.

Question 9

What are important facts o the Atlas?

Answer 9

The Vertebra has no vertebral body or spinous process.
It is a ring of a bone with anterior and posterior arches and a large lateral masses.
The superior articular facets are concave and conect with the occiptital Condyle.
The inferior parts of the articular facets articulate with the C2 transverse processes.

Question 10

What are facts about the thoracic vertebra?

Answer 10

They are considerably larger and stronger than C1-7.

The Spinous processes of the T1-T10 are laterally flattened and directed inferiorly.
