bröstkota

A bröstkota, or thoracic vertebra, is one of the twelve vertebrae located in the thoracic region of the spine. This region is situated between the cervical (neck) vertebrae and the lumbar (lower back) vertebrae. Each bröstkota is uniquely shaped and plays a crucial role in supporting the upper body and protecting the spinal cord.

The thoracic vertebrae are characterized by their connection to the ribs. Each bröstkota has articular facets that articulate with the heads of the ribs, forming the costovertebral joints. These joints allow for the movement of the rib cage during respiration. The spinous processes of the thoracic vertebrae are typically long and slant downwards, overlapping the vertebra below. This arrangement contributes to the stability of the thoracic spine.

The thoracic spine, with its bröstkotor, forms a relatively rigid section of the vertebral column, which helps to protect the internal organs of the chest, such as the heart and lungs. The curvature of the thoracic spine is kyphotic, meaning it curves outwards. This natural curve is essential for maintaining posture and shock absorption. Injuries to the bröstkotor can range from minor strains to severe fractures, potentially impacting mobility and causing pain.
