What are the 26 bones that make up your backbone called?

It consists of 26 bones called vertebrae. The bottom two vertebrae consist of fused bones, five in the upper one and four in the lower one. Each vertebra has a strong, stubby section that supports your weight, and a hole for the spinal cord to pass through. Humans and giraffes both have seven neck bones.

What are the 7 bones in the neck?

It consists of 7 bones, from top to bottom, C1, C2, C3, C4, C5, C6, and C7. In tetrapods, cervical vertebrae (singular: vertebra) are the vertebrae of the neck, immediately below the skull. Truncal vertebrae (divided into thoracic and lumbar vertebrae in mammals) lie caudal (toward the tail) of cervical vertebrae.

What bones make the backbone?

The vertebrae (back bones) of the spine include the cervical spine (C1-C7), thoracic spine (T1-T12), lumbar spine (L1-L5), sacral spine (S1-S5), and the tailbone. Each vertebra is separated by a disc. The vertebrae surround and protect the spinal cord.

Are ribs bones?

rib, any of several pairs of narrow, curved strips of bone (sometimes cartilage) attached dorsally to the vertebrae and, in higher vertebrates, to the breastbone ventrally, to form the bony skeleton, or rib cage, of the chest.

What is Flavum?

What are the bones of the back or spine called?

What are the lower back bones?

Lower Back and Superficial Muscles. Sacrum: This triangle-shaped bone is made up of five fused vertebrae. It fits like a wedge into the back of the pelvis at the hips. Coccyx: This small bone is better known as the tailbone.

What are the bones in your back?

Your back is composed of twenty-four individual bones called vertebrae that are stacked one on top of the other to make up your backbone or spinal column. The entire column sits on the sacrum, a large triangular bone that connects the spine to the hips. The top seven vertebrae in the neck are called the cervical spine.
