Smooth muscle – located in various internal structures including the digestive tract, uterus and blood vessels such as arteries.
Cardiac muscle – the muscle specific to the heart.
Main role is too provide movement and stability
Describe the Synovial membrane
This makes synovial fluid which lubricates joints
Describe synovial fluid
Thick liquid that lubricates joints
Describe Ligaments
connective tissue that connects bones to bones
Discribe Tendons
Connective tissue that connects bone to muscle
cartilage
Cartilage is a connective tissue found in many areas of the body including: Joints between bones e.g. the elbows, knees and ankles.
Types of synovial joints
Ball and socket
Hinge
saddle
describe synovial joint
