Vertebral Column Anatomy Quiz: Learn Human Vertebrate Structure

The vertebral column is formed by vertebrae that can be divided into four regions.

The first two vertebrae are known as the axis and the atlas respectively.

There are 10 pairs of ribs attached to the sternum.

The clavicle is a large flat bone located laterally in the upper part of the back.

The forearm contains two bones - the radius and the ulna.

The pelvic girdle is composed of three large hip bones.

The cervix region of the vertebral column has five lumbar vertebrae.

The ribcage contains ten pairs of ribs that extend from the vertebral column to the sternum.

The scapula forms the front of the shoulder girdle.

The arm contains two large bones - the radius and the ulna.

The forearm articulates with the humerus proximally.

The pelvic girdle is formed by two large hip bones, a sacral bone, and a coccygeal bone.

Vertebral Column

Divided into five regions: cervix (7 cervical vertebrae), thorax (12 thoracic vertebrae), lumbus (5 lumbar vertebrae), sacrum (5 sacral vertebrae welded into one sacral bone), and coccyx (4 coccygeal vertebrae welded into one coccygeal bone)
The first two vertebrae are the atlas and axis respectively

Ribcage

Contains 12 pairs of ribs
The first 7 pairs extend from the vertebral column to the sternum
The next 3 pairs are attached with cartilages to the sternum
The last 2 pairs are unattached (floating)

Shoulder Girdle

Composed of the scapula and clavicle
The scapula is a large flat bone located laterally in the upper part of the back
The clavicle is a thin bone attached medially to the sternum and laterally to the scapula

Arm and Forearm

The arm contains one large bone – the humerus, which articulates with the scapula in the shoulder joint
The forearm has two bones: the radius and ulna, which articulate with the humerus proximally
The radius also articulates with the three carpal bones of the wrist distally

Pelvic Girdle

Composed of two large hip bones that form the front and sides, and the sacral and coccygeal bones that form the back
