Jointed limbs are an important evolutionary development because they allow animals to have a wider range of motion and increased flexibility in movement. This can help with activities such as hunting, escaping predators, and mating. Jointed limbs also enable animals to adapt to various environments and perform specialized tasks.
If you count the true arm: The shoulder has a ball and socket joint. The elbow has a hinge joint (ulna) and a pivot joint (radius). If you count the forearm: The forearm has a fibrous joint (syndesmosis) between the radius and ulna. The wrist is a very complex set of joints, if I remember correctly they are mostly saddle joints and gliding joints.
The functions of limbs in animals can vary depending on their evolutionary adaptation and environmental niche. Some animals may use their limbs for modes of locomotion, such as walking, running, or swimming, while others may use them for grasping, climbing, or digging. Overall, the functions of limbs in different animals are diverse and tailored to their specific needs.
Apodicular joints are joints in arthropods that allow for movement and flexibility, such as in the limbs of insects. These joints enable arthropods to perform various activities, including walking, jumping, and grasping objects. The structure of apodicular joints can vary depending on the specific type of arthropod and its functional requirements.
Upper limbs have arms, hands, and fingers, while lower limbs have legs, feet, and toes. Both upper and lower limbs are important for various activities such as movement, balance, and fine motor skills.
immovable joints can't move and movable joints could move they are the same because immovable joints and movable joints are both made up of two or more jointsDifference: the movable joint moves, and the unmovable joint, does not.Alike: they both consist of 2 joints or more.
Diarthroses joints are movable joints. More movement is required in the limbs of the appendicular. Synarthroses joints are immovable joints and amphiarthroses are semimovable joints. Less movement is required in hte axial skeleton than in the appendicular skeleton.
Joints connect two bones together. They allow for movement and provide stability to the skeletal system. Joints can be classified as immovable (like those in the skull) or movable (like those in the limbs).
The limbs are joined to the torso through joints such as the shoulder and hip joints. These joints provide mobility and allow for movement of the limbs in different directions.

A lion has around 230 joints in its body, which includes the joints in its limbs, spine, and skull.

For certain all higher animals do. It also depends on your meaning of limbs. But, all Chordata have a backbone. Only Vertebrate that does not have limbs, if your are defining limbs to be legs and arms, are the fish. The term use to describe 4 limbed animals is tetrapod.
They can be called limbs, appendages, extremities, or members.
no sea creatures have limbs and the other animals and humans have legs
