sliding friction is when you are sliding
Joints that allow movement in a single plane are called trochlear joints, also known as hinge joints. Examples of such joints are the knee and the humero-ulnar joint of the elbow. Technically the knee does rotate slightly in the last few degrees of extension which is called the "screw home mechanism", but is still considered a hinge joint.hinge
The knuckles are examples of hinge joints, which allow movement back and forth in one direction, such as bending and straightening the fingers.
Asymmetrical joints are joints in the body that allow movement in one plane or direction only, restricting movement in other planes. Examples include the elbow and knee joints, which primarily allow flexion and extension but have limited rotational movement. These joints provide stability and support for specific types of movements.
The overall purpose of a joint is to provide movement . Differing types of joints allow for differing movements; a hinge joint allows motion in one direction whereas a pivot joint allows rotating or twisting motion.
Yes, leg joints primarily bend in one direction. For example, the knee joint typically allows for flexion and extension, meaning it bends forward and straightens out. Similarly, the ankle joint permits upward and downward movement of the foot. However, some joints, like the hip, allow for movement in multiple directions, including rotation.
One-directional bending muscles are known as unipennate muscles. These muscles have fibers that insert obliquely into a central tendon on one side. An example is the flexor pollicis longus in the hand.
A periscope looks like a long pipe with a bend on either end. One bend faces a direction, and the other bend faces the opposite direction.

No bone can bend one way. I think you meant which joint can only bend one way. For instance, the elbow and knee joints are classed as hinges, and tend to move forward and backwards like door hinges.

A hinge joint, like the knee or elbow, allows bones to move backward in only one direction. This type of joint allows for bending and straightening movements, providing stability and control during activities like walking or weightlifting.
a joint called the hinge joint allows you to bend and straighten your knees!!:)
The shoulder is one of the best known "ball-&-socket joints." It is a freely moveable joint.
The knuckles are examples of hinge joints, which allow movement back and forth in one direction, such as bending and straightening the fingers.
Because they are joints that hinge. A hinge can only go one direction. Like for example, a door hinges, and it can only go one direction unless you break the door. Then the door could go anywhere, but hinges only move one direction.
Hinge joints like the elbow and knee are designed to allow movement primarily in one plane, enabling flexion and extension. This unidirectional movement is due to the structure of the joint, where the articulating surfaces are shaped to fit closely together, limiting motion to a specific direction. This design enhances stability and efficiency during activities such as walking and lifting, while also protecting the joint from injury by preventing excessive movement in other directions.
