True
Study Notes
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
Test your knowledge on the anatomy of the human vertebral column, including the different regions and types of vertebrae. Learn about the specific characteristics of the cervical, thoracic, lumbar, sacral, and coccygeal vertebrae.
