Although your question is not precise, but I'll answer it
1- The knee joint which is a biaxial synovial joint of the condyloid variant
it is formed by the 2 long bones femur & tibia
2- The elbow joint which is a uniaxial synovial joint ( hinge variant )
it is formed by three long bones humerus, radius, and ulna
Joints are where 2 bones meet so I suppose you could call them bones but really they are a different thing all together
The articulation of two or more bones is called a joint. Joints are where bones come together and allow movement in the body.
1. Bony Fusion- bones fused together; no movement (also called synostoses joints)2. Fibrous Joints-immovable joints (synarthroses) that have fibrous connective tissue between the articulating bones; little to no movement3. Cartilaginous Joints- cartilage between the bones4. Synovial Joints- have a joint cavity lined by a synovial membrane
ACCORDING TO MUHAMMAD (SAWW)"Everyone has been created with three hundred and sixty Joints"TODAY ANATOMY AND ANOTOMISTS PROVE ITFirst: 147 joints in the vertebral column25 joints between the vertebrae.72 joints between the vertebrae and the ribs.Second: 24 joints in the thorax2 joints between the bones of the sternum and the thoracic cage.18 joints between the sternum and the ribs.2 joints between the clavicle and the scapulae (shoulder blade).2 joints between the scapulae and the thorax.Third: 86 joints in the upper extremity2 joints between the scapular bones.6 joints between the elbows.8 joints between the wrists.70 joints between the hand bones.Fourth: 92 joints in the lower extremity2 hip joints.6 joints between the knee bones.6 joints between the ankles.74 joints between the feet bones.Fifth: 11 joints in the Pelvis4 joints between the coccyx vertebrae.6 joints between the bones acetabulm.1 joint of the pubic sumphysis.Total number of joints: 360EVERY THING THAT PROPHET TOLD US IS A NODE FOR US AND IF WE ARE WISE WE SHOULD ADOPT IT as it is said"A NODE TO WISE"
hunting large monsters would produce large bones. no specific wyvern or pelagus gives that.
The 2nd through 5th digits on both hands have 3 bones (proximal, middle and distal phalanges) and 3 joints, including the metacarpophalangeal, proximal and distal interphalangeal joints. The 1st digit, however, only has 2 bones and 2 joints.
1)the shape of the articulating bones, 2) the flexibility of the ligaments that bind the bones toghether, and 3) the tension of associated muscles and tendons.
Joints are located where two bones connect. They allow movement and provide mechanical support.
Joints are classified into 3 types 1) Fibrous, includes joints between skull bones 2) Cartilaginous, includes A) Primary, means there is a sheet of cartilage between bones ( Epiphysis and diaphysis, so that bone can grow in length and get ossified, when growth stops. B) Secondary cartilaginous joints in witch a thin plate of cartilage persists like pubic symphysis. 3) Synovial type of joints, including all mobile joints like shoulder, elbow, hip, knee and ankle joints. They have Synovial membrane.
Bones classified into four groups. Long bones,Short bones,Flat bones, and Irregular bones
The subclasses of synovial joints are plane joints, hinge joints, pivot joints, condyloid joints, saddle joints, and ball-and-socket joints. These subclasses vary in the types of movement they allow and the shapes of the articulating surfaces of the bones involved.
