Chapter 9 Flashcards
A joint is a point of contact between
Two or more bones, cartilage and bone or teeth and bone
Synarthroses
No movement ex: sutures
Amphiarthroses
Little movement ex: pelvis, intervertebral discs
Diarthroses
Freely moveable ex: hip, knee, shoulder, elbow
Synovial joints
Articulate cartilage on ends of long bones and a synovial cavity between articulating bones surrounded by accessory ligaments; freely moveable
Examples of synovial joints
Hip, knee, shoulder, elbow
Cartilaginous 2
Synchondrosis, hyaline cartilage; no movement and symphysis- fibrocartilage; some movement
Example of synchondrosis structure
Epiphyseal plate
Example of symphysis structure
Pubic symphysis
Fibrous structures
Sutures, dense fibrous - syndesmoses, more dense than fibrous- interosseous membranes- a broad sheet of dense fibrous
Example of syndesmoses
Gomphosis
Examples of interosseous
Between ulna and radius
Characteristics of fibrous joints
Little to no movement, 3 types: sutures, syndesmoses, interosseous membranes, held together with dense fibrous connective tissue, lack a synovial cavity
Characteristics of Cartilaginous Joints
Lack a synovial cavity, bones are held together with cartilage connective tissue, permit little or no movement 2 types: synchondrosis,symphyses
Characteristics to synovial joints
Have a synovial cavity, articulatng bones are covered with articulate cartilage & held together by ligaments, contain synovial fluid, have a nerve and blood supply, are surrounded by an articulate capsule, permit a large range of movement
