Answer :
Final answer:
The thoracic region is prone to degenerative diseases like osteoporosis due to its structural responsibilities and articulation with the ribs. Osteoporosis causes a decrease in bone density, leading to the collapse of thoracic vertebrae and resulting in kyphosis, characterized by an excessive curvature of the spine.
Explanation:
The thoracic region is a common area for degenerative diseases such as osteoporosis, primarily because of its structure and function. The thoracic vertebrae, comprising 12 segments (T1-T12), play a significant role in the support and stability of the upper body, in addition to articulation with ribs. Osteoporosis, an age-related bone disease, leads to a decrease in bone density and strength. When the thoracic vertebrae are affected by osteoporosis, it may result in their gradual collapse. This can cause an exaggeration in the natural curvature of the spine known as kyphosis, presenting itself as an excessive curvature of the thoracic region, ultimately affecting posture and sometimes resulting in pain and reduced mobility.
