Each vertebra (pl.: vertebrae) is an irregular bone with a complex structure composed of bone and some hyaline cartilage, that make up the vertebral column or spine, of vertebrates. The proportions of the vertebrae differ according to their spinal segment and the particular species.

The vertebral column has four main functions: Protection – encloses and protects the spinal cord within the spinal canal. Support – carries the weight of the body above the pelvis. Axis – forms the central axis of the body.

A typical vertebra consists of two parts: the vertebral body (or centrum), which is ventral (or anterior, in the standard anatomical position) and withstands axial structural load; and the vertebral arch (also known as neural arch), which is dorsal (or posterior) and provides articulations and anchorages for ribs and core skeletal muscles.

Feb 3, 2023 · The spinal column, also known as the backbone or vertebral column, is made up of 33 individual bones called vertebrae. The vertebrae are stacked on top of each other and separated by intervertebral discs, which act as shock absorbers.

The vertebral column, commonly known as the spine, spinal column, or backbone, is a flexible hollow structure through which the spinal cord runs. It comprises 33 small bones called vertebrae, which remain separated by cartilaginous intervertebral discs. The vertebral column forms the axial skeleton, skull bones, ribs, and sternum.

Aug 8, 2023 · The vertebral column (spine) defines the animal subphylum Vertebra, or vertebrates, of the phylum Chordata. In humans, it is composed of 33 vertebrae that include 7 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 4 coccygeal. Along with the skull, ribs, and sternum, these vertebrae make up the axial skeletal system.

Sep 12, 2023 · Structure and function of the vertebral column. The vertebral column (spine or backbone) is a curved structure composed of bony vertebrae that are interconnected by cartilaginous intervertebral discs. It is part of the axial skeleton and extends from the base of the skull to the tip of the coccyx. The spinal cord runs through its center.

Apr 17, 2019 · Vertebrae vary in their shape based upon the region of the body that they are found in, as well as what species they belong to. The main portion of the vertebra is the body, which is divided into two parts: the centrum and the posterior vertebral arch (also called the …

Apr 9, 2025 · vertebral column, in vertebrate animals, the flexible column extending from neck to tail, made of a series of bones, the vertebrae. The major function of the vertebral column is protection of the spinal cord; it also provides stiffening for the body and attachment for the pectoral and pelvic girdles and many muscles.
