Articulating bones:
Bones that meet at a joint to enable movement
The 6 functions of the skeleton:
Many: movement (muscles contract & pull on the bone)
People: protection (vital organs)
Bring: blood cell production
Super: shape and structure (maintaining basic form of our body)
Sugary: support (for muscles and vital organs)
Sweets: storage (of minerals)
Synovial joints are also known as:
Freely moveable joints
Synovial joint:
An area of the body where two or more articulating bones meet
Tendons:
Verŷ strong non elastic chords that attach MUSCLE TO BONE
Bursae:
Sack filled with liquid, floating inside the joint, to reduce friction between tendon and bone
Cartilage:
a tough but flexible tissue that acts as a buffer between the bones, preventing bone rubbing together (causing friction)
Synovial fluid:
A clear and slippery liquid that lubricates the joint and stops the bones rubbing together
Ligaments:
Bands of elastic fibre that attach BONE TO BONE, keeping the joints stable by restricting movement
Synovial membrane:
The lining inside the joint capsule that secretes synovial fluid
Joint capsule:
Tissue that stops synovial fluid from escaping and encloses, supports, and holds the bones together
