Your thumb is a saddle joint, and your fingers are hinge joints.
There are eight carpal bones that make up the wrist joint in the hand.
Your hand joints ?
The joints in your ankles and wrists are gliding joints. (Holding your forearm steady while your hand is upward and then wave side-to-side with your hand is an example).
The metacarpophalangeal joints attach the fingers to the hand.
There are five interphalangeal joints in one anatomically normal hand, which includes the thumb. Each finger (excluding the thumb) has three interphalangeal joints, while the thumb has two interphalangeal joints.
The hand consists of the metacarpophalangeal and interphalangeal joints. The metacarpophalangeal joints connect the fingers to the hand, while the interphalangeal joints connect the finger bones (phalanges) to each other.

The human hand has 27 bones, 14 of which are phalanges, or fingers. The metacarpals are the bones that connect the fingers and the wrist. Each hand has five metacarpals. The thumb is connected to the trapezium and the joints are called metacarpophlangeal joints.
Joints are located where two bones come together. There are ball and socket joints, there are hinge joints, there are saddle joints there are pivot joints, there are gliding joints and there are condyloid joints. There are 27 bones in the hand alone so there are more than 27 joints in the hand. There are 39 joints in each arm. There are over 300 joints in the human body. There is not enough room to give you an answer for each joint in the human body.
When the baseball hits your hand, its energy will be transferred to your hand and arm (and to some extent, the rest of your body and everything its in contact with). This energy will move your hand backwards suddenly. If the joints in your arm are already near their' limits then this transfer of energy may damage the joints. Extending your hand forward prevents this.Read more: Why_is_it_best_to_extend_your_hand_forward_when_catching_a_fast_moving_baseball
Flanges in the hand typically refer to the joints where the fingers meet the palm. They provide stability and range of motion for grasping and manipulating objects. These joints are also known as metacarpophalangeal joints or knuckles.
