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.

∙ 13y agoThe most movable joints in the limbs are the shoulder and hip joints. These are ball-and-socket joints that allow for a wide range of motion in multiple directions.

∙ 13y agoMost joints within the skeletal system are synovialjoints. Which allow free movement. They are more complex structually than fibrous or connective joints.

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.
ribs and vertebrae (semi mobile joints) vertebrae (cartilaginous joints) elbow & knee (hinged joints), hip and shoulder (ball and socket joints), neck (rotational glide), wrist (compound rotational).
Limbs are the parts of the body used for movement and manipulation, such as arms, legs, and wings. Ligaments are tough bands of tissue that connect bones to other bones at the joints, providing stability and limiting movement to prevent injury.
Most amphibians have four limbs. However, some species have lost limbs or adapted to different environments, leading to variations in the number of limbs among different amphibian species.

Diarthroses, which are freely movable joints, are found in the limbs to allow for a wide range of motion needed for activities like walking and grasping. Synarthroses and amphiarthroses, which are less movable or immovable joints, are found in the axial skeleton to provide stability and support to the body's core and protect vital organs. This distribution of joint types reflects the different functions and biomechanical demands of the limbs and axial skeleton.
The millipede has the most limbs of any animal, with up to 750 legs.
The knuckles are the bony parts located at the base of each finger where they join the hand. They are important for gripping and provide structural support to the fingers.
Yes, humans do have hinge joints. The elbow and knee joints are examples of hinge joints that allow movement in one direction, similar to the opening and closing of a door. These joints provide stability and help facilitate activities like bending and straightening the limbs.
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.
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).
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.
Yes, reptiles typically have limbs. Most reptiles have four limbs, although some species have lost their limbs or have reduced limb size through evolution. These limbs are adapted for walking, climbing, or swimming, depending on the species.
Yes, amphibian skeletal structure includes joints for limbs and other body parts, just like we have.
No, the most common type of joints in the human body are synovial joints, which are characterized by the presence of a synovial cavity. Bony joints, also known as synostoses, result from the fusion of bones and are less common in comparison.
They need skeleton for strength , support ,firmness of body and in most of the cases in some bones ,bone marrow helps in the formation of blood .e.g. human beings.
