What are the types of joints found in thumb?
The types of joints found in thumb are: 1. Caropometacarpal joint where the metacarpal bone of the thumb attaches to the trapezium bone of the wrist. This joint is a saddle joint that allows two planes of motion with a small amount or rotation. 2. Metacarpophalangeal joint is the joint between the metacarpal bone and the phalanges of the thumb. This joint is an ellipsoid joint that allows movement in two planes and is biaxial. 3. Interphalangeal joint is the joint between the two phalanges of the thumb. This joint is a hinge joint that allows movement in one plane and is also referred to as uniaxial.

Why is thumb wider and shorter than other thumb?
The thumb also has three joints, but the Proximal joint is farther up, embeded and mostly concealed in its muscles. That third [base joint] is what allows you to move the thumb to the left or right. NO. If you consider the thumb to have three joints you must be including the carpometacarpal joint which is (as far as i remember) a double saddle synnovial joint. This is the joint that joints the bone of the thumb that is concealed in the hand to the bones of the wrist. Within the visible thumb there is only two joints, the first being between the metacarpal and the proximal phalanx and the second being between the proximal and dislat phalanges. The other digits have and extra bone in the middle of these phalanges called the middle phalanx, giving it a third joint in the visible digit, or if you are including carpometacarpal joints as the original answer does with the thumb then you must do so for the fingers also which means they would have 4 joints each. And to answer the question the presence of a third joint in the thumb is simply unnecessary thanks the range of movement. The other digits require the extra joint so that the tips can come to meat close to the base of the visible digits so that before thumbs had evolvfed we could grasp small thin objects. The thumb has such a range of movement that this extra joint would be more effort to supply than its worth.
What type of joint is the thumb joint?
saddle joint- This joint has two bones that fit together in a special way. It can move in all directions, except rotational. It's what makes us different from monkeys as they can't move their thumbs!
What type of movement does the saddle joint allow?
The saddle joint is unique to humans and is located at the base of each thumb. It allows the thumb to touch the pinky finger by crossing over the palm of the hand. This allows humans to produce fine movements including sewing, writing, portrait painting, and anything other type of movement where the hand grasps a tool or the object itself as in pottery or peeling an orange.
What type of joint is the saddle joint?

Are there natural single-joint movements?
An exercise like a bicep curl would be an example of a single joint movement. You can also move your thumb by the gliding joint that attaches it to the hand. I'm sure there are many others.
