What Are the Small Bones of a Spinal Column Called

The human body has an intricate system of bones, muscles and other components that enable us to move and function. This system is known as the musculoskeletal system. One of the most important parts of this system is the spinal column, which is made up of small bones called vertebrae. In this article, we will explore the anatomy of the spinal column and the small bones that make it up.

Anatomy of the Spinal Column

The spinal column, also known as the vertebral column or spine, is a complex structure that forms the main support of the body. It is made up of 33 vertebrae and runs from the base of the skull to the lower back. It is divided into four sections: cervical, thoracic, lumbar, and sacral. Each section contains a different number of vertebrae, with the cervical region having seven vertebrae, the thoracic region having 12 vertebrae, the lumbar region having five vertebrae, and the sacral region having five vertebrae.

The spinal column is responsible for protecting the spinal cord, which is a bundle of nerves that runs through the center of the vertebrae. It also helps to support the body, allowing us to stand upright and providing stability when we walk, run, and move.

Small Bones of the Spinal Column

The small bones that make up the spinal column are called vertebrae. Each vertebra is a small, round bone that is separated from the other vertebrae by cushion-like discs, which are made of cartilage. These discs act as shock absorbers, helping to protect the spinal cord and vertebrae from damage.

The vertebrae are held together by ligaments that connect them to each other and to the bones of the rib cage. The vertebrae also contain foramina, which are small openings that allow the spinal nerves to pass through.

The vertebrae in the cervical region of the spine are the smallest, and they help to support the weight of the head. The vertebrae in the thoracic region are slightly larger and are connected to the ribs, while the vertebrae in the lumbar region are the largest and are responsible for bearing the weight of the upper body.

The small bones of the spinal column, called vertebrae, are essential for providing protection and support for the body. They are connected to each other and to the bones of the rib cage,

The spine is a vital part of the body, and is made up of several distinct parts. The spine is composed of 33 bones, ranging from the vertebrae of the neck to the lumbar vertebrae of the lower back. These bones all provide support and flexibility to the body, allowing us to move and bend freely.

The small bones of the spine are also known as vertebrae, and they’re put together to form the spinal column. Vertebrae are divided into categories based on their location in the back — seven cervical (neck) vertebrae, 12 thoracic (mid back) vertebrae, five lumbar (lower back) vertebrae, five sacral (pelvis) vertebrae, and four coccygeal (tailbone) vertebrae. Each of these bones has a distinct shape and structure, and is important for our body’s movement and posture.

The small bones of the spinal column are connected through various large and small ligaments, muscles, tendons, and fascia. They also contain discs of cartilage that serve as cushions between each vertebra. This helps to allow and maintain flexibility in the spine and prevents the vertebrae from rubbing against each other.

The structure of the spine is essential for our body’s movement and overall health. It’s important to be aware of the structure and role of the small bones of the spine, and to maintain proper posture to help keep your muscles and ligaments balanced and healthy.
