tendons and ligaments
The grooves and ridges on the outside of the bone provide attachment points for muscles, tendons, and ligaments. These features help to anchor these soft tissues to the bone, allowing for movement, stability, and support of the musculoskeletal system.
The ridges and grooves on the brain are found on the cerebral cortex, which is the outermost layer of the brain. These ridges and grooves are known as gyri (ridges) and sulci (grooves), and they increase the surface area of the brain, allowing for more neural connections and processing power.
The brain is covered in ridges (gyri) ans grooves (sulci).

The metal ridges between the spiral grooves on the inside of a rifle barrel are called lands. They are part of the rifling, which imparts a spin to the bullet as it travels down the barrel, enhancing accuracy and stability in flight. The grooves are the recessed areas that help guide the bullet, while the lands engage the bullet, ensuring a tight fit and promoting a more consistent trajectory. Together, lands and grooves are essential for improving the performance of a firearm.
