A ball and socket joint is a type of joint in the body enabling extensive movement. It features a rounded end of one bone fitting into a cup-shaped socket of another bone. This design allows diverse movements like rotation, bending, straightening, and side-to-side motion. Examples include the hip and shoulder joints, facilitating a wide range of motion in various directions for physical activities.
In the skull, most bones are fixed to protect the brain. However, two bones are movable: the mandible (lower jaw) and the hyoid bone. The mandible enables essential functions like chewing and talking by moving up and down. The hyoid bone, located in the neck, is also movable, aiding in swallowing anRead more

Our elbow joint allows bending and straightening but limits backward movement to prevent overextension. The joint consists of bones, ligaments, and muscles designed to restrict motion beyond a certain range. This limitation ensures stability, preventing injuries that might occur if the elbow were toRead more
Our elbow joint allows bending and straightening but limits backward movement to prevent overextension. The joint consists of bones, ligaments, and muscles designed to restrict motion beyond a certain range. This limitation ensures stability, preventing injuries that might occur if the elbow were to move backward excessively. It safeguards the joint’s health and functionality during daily activities.

A habitat is a natural environment where plants or animals live and survive. It includes everything an organism needs: food, water, shelter, and climate. Habitats vary, like forests, deserts, oceans, and more, providing specific conditions for different forms of life to thrive. It’s the home where organisms find everything necessary for their survival and growth.
Cacti survive in deserts due to unique adaptations. They store water in their thick stems, enabling survival during dry spells. Modified leaves or spines reduce water loss. Shallow but broad root systems quickly absorb surface water. Cacti use CAM photosynthesis, reducing water loss during the day.Read more
