3. Receive the most stress: Lumbar

4. Attach to ribs: Thoracic

5. Articulates with hip bones of the pelvis: Sacrum

Explanation:

The vertebral column is a <u>series of 33 bones called vertebrae</u> that play a key role in organ protection, movement of body, and overall support. The column has been divided into <u>5 different regions</u> with the number of bones.

<u><em>1. Cervical Vertebrate</em></u><u>:</u> These are the group of <u>seven vertebrae of the neck</u>, start immediately below the skull. Two cervical bones C1 and C2 are unique in function. They are responsible for the movement of the head.  They have <u>transverse foramina</u> which <u>gives passage to vertebral artery and vein</u>.

<em><u>2. Thoracic Vertebrae:</u></em> They are a group of twelve small bones that form the vertebral spine in the upper trunk. The function of the thoracic vertebrae is to articulate with ribs to produce the bony thorax.

<em><u>3. Lumbar Vertebrae: </u></em>This is the largest segment of the vertebral column that consists of 5 bones between the rib cage and pelvis. They <u>carry all of the upper body weight</u> providing flexibility and movement to the trunk region.  This is why it can <u>receive the most stress easily</u>.

<em><u>4. Sacrum Vertebrae: </u></em>There are 5 sacral vertebral fused bones. It <u>connects to the hip bones and play role in forming a strong pelvis</u>.

<em><u>5. coccyx Vertebrae:</u></em> These are a group of 4 fused bone. There is <u>no vertebral canal due to a lack of vertebral arches</u>. They <u>provide </u>an <u>attachment site for muscles</u> ligament and tendons. They also <u>play a role in stabilization and support</u> while sitting.
