The type of movement that bends the knee and brings the lower leg backward toward the thigh is called knee flexion. This occurs when the hamstring muscles contract, pulling the lower leg (tibia and fibula) toward the back of the thigh (femur). Knee flexion is essential for various activities such as walking, running, and sitting.

Glide movement of the mandible involves sliding the lower jaw forward or backward in a smooth linear motion. Hinge movement of the mandible involves opening and closing the jaw like a hinge, allowing for the up and down motion of the lower jaw. These movements are essential for functions such as chewing and speaking.
Trunk bending refers to the movement of the torso forward, backward, or sideways. It involves flexion, extension, or lateral flexion of the spine to bring the upper body closer to the lower body or to move it away from the midline. Trunk bending exercises are common in fitness routines to improve core strength and flexibility.
Caudad is an anatomical term that refers to a direction toward the tail or posterior part of the body. In humans, it describes movement or location toward the lower end of the spine, or away from the head. It is often used in contrast to "cranial," which indicates a direction toward the head.
Inferior or caudal mean toward the lower part of the body.

The joint movement that occurs when you turn your foot toward the other foot is called "adduction." This movement involves the foot moving inward, towards the midline of the body. It primarily occurs at the ankle joint and involves the action of certain muscles in the lower leg and foot. Adduction is commonly seen in various activities, such as crossing your legs or bringing your feet together.

The muscle responsible for elevating and retracting the lower jaw is the temporalis muscle. This fan-shaped muscle is located on the side of the head and plays a key role in the process of mastication (chewing). When it contracts, it not only raises the mandible but also pulls it backward, contributing to the retraction movement.
