The shoulder joint is not harder to move, it just moves differently. It is a ball and socket joint, giving it a wider range of movement, but the elbow is a synovial joint, which can only move in one direction. The reason that yo may find it harder to move your shoulder is because the muscles pulling it may be less developed and also it has to pull up an entire arm, not just a forearm.
A joint is where two sections of something come together. With bones, your elbow, knee, jaw, fingers, etc. are all mobile joints, because they move. A rigid joint would be where the bones don't move; your skull has various bones that connect but do not move.
it is a mobile joint! It is a mobile joint because it allows the door to move through the hinges!! Are arms are also mobile joints because are arms also move
Primarily your Hip joint with its ball and socket, supplemented by the articulations of knee and ankle.
The pivot joint only "folds & straightens" whereas a ball and socket can move in any direction AND twist.
Neck, elbow, knees, hips, ankle, wrists, phalanges, lower phalanges (toes), and shoulders and spine.
Joint Laxity
A lat pull down will move the shoulder and elbow the most, primary is probably shoulder.
this is because the partially movable joint wont move as easy r quickly as that of the elbow joint.
First flexion at the elbow, rotation at the shoulder and then abduction of the upper arm. The joint at the wrist doesn't change position.

The 'ulnar' articulates on the 'humerus'. The 'radiu's also articulates in the 'humerus'.
because it is an hinge joint
Chickens use their wings to fly, since humans can't fly there's really no part of the human body that corresponds to the wing of a chicken. Many people would suggest an arm because when bent, an arm may look like a chicken wing.
The elbow is a hinge type joint, so it will flex and extend with minimal rotation.
Your arm connects and lets you move your shoulder, elbow, and wrist.
It's a 'hinge' joint - it can only move in two directions (forward and back).
