Joints

structurally and functionally

• Fibrous joints
• Cartilaginous joints
• synovial joints

• have no synovial cavity and the bones are held together by dense irregular connective tissue
• ex. sutures between skull bones

no synovial cavity bones are held together by cartilage

only one with a synovial cavity united by dense irregular tissue.

• Synarthrosis, imovable 
• Amphiarthrosis slightly moveable
• Diarthrosis freely movable

amphiartrosis

• synchondrosis, (synarthrosis)
• symphysis(amphiarthroisis

articular cartilage and articualr capsule

covers the ends of bones to absorb shock

innerlayer synovial membrane that secretes synovial fluid incapsulate the joint

sac made synovial membrane contains fluid located where friction can occur ex, between anything and bones

protect reduce friction by lubracting the joint, supplying nutrients
