What causes bone to become ridged and grooved?

Bone can become ridged and grooved due to various factors, including mechanical stress and strain from physical activity, which stimulate bone remodeling. This process is influenced by the activity of osteoblasts and osteoclasts, cells responsible for bone formation and resorption, respectively. Conditions like Arthritis or certain metabolic disorders can also lead to abnormal bone surface changes, resulting in ridges and grooves. Additionally, age-related changes and genetic factors may contribute to the texture of bones.
