Study Notes

Human Skeleton

The adult human skeleton consists of 206 bones.

Thorax (Chest)

The chest (thorax) is composed of 52 bones, including the sternum, ribs, and thoracic vertebrae.

Spine Composition

The spine is composed of 33 vertebrae: 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, 5 sacral vertebrae, and 4 coccygeal vertebrae.
The cervical vertebrae are located in the neck, the thoracic vertebrae in the chest, the lumbar vertebrae in the lower back, the sacral vertebrae in the pelvis, and the coccygeal vertebrae at the bottom of the spine.

Ribs and Breastbone

12 pairs of ribs are connected to the breastbone (sternum) by cartilages.

Largest Vertebra

The largest vertebra in the spinal column is typically the fifth lumbar vertebra (L5).
