Joints AP1
| Question | Answer |
|---|---|
| Junctions between bones | joints (articulations) |
| Hold bones together | joints |
| Allow flexibility for movement | joints |
| Immoveable joints | synarthrosis |
| Slightly moveable joints | amphiarthrosis |
| Freely moveable joints | diarthrosis |
| Joined together by fibrous tissue (no joint cavity present) | Fibrous Classification of Joints |
| Three types of Fibrous joints | suture, gomphosis, and syndesmosis |
| Sutures | found in Sutures of skull (immoveable) |
| found between tibia and fibula (slightly moveable) | syndesmosis |
| tooth sockets (immoveable) | Gomphosis |
| Joined together by cartilage (no joint cavity present) | cartilaginous joints |
| Two types of Cartilaginous joints | symphysis and synchondrosis |
| What type of cartilage is Synophysis? | fibrocartilage |
| What type of cartilage is Synchondrosis? | Hyaline cartilage |
| Found in pubic symphysis and intervertebral joints | symphysis joint |
| Found in epiphyseal plates | synchondrosis |
| Found only in Children and infants | epiphyseal plates |
| 6 types of synovial joints | Ball-and-socket, hinge, condylar, pivot, saddle, plane |
| All contain articular cartilage, a synovial membrane, and a joint cavity filled with synovial fluid | synovial joints |
| Found in hip and shoulder | Ball-and-socket joint |
| Found in elbow, knee, and interphalangeal | hinge joint |
| Found between radius and carpals, and between metacarpals and phalanges | condylar joints |
| Found between radius and ulna; found around dens at atlas | pivot joints |
| Found at base of thumb with trapezium | saddle joints |
| Found in intercarpals and intertarsals | plane joints |
| Multiplanes | multiaxial |
| 2 planes | biaxial |
| 1 plane | uniaxial |
| Joint cavity present which is filled with synovial fluid which lubricates and removes wastes | synovial joint |
| Sliding or twisting | plane |
| Rounded process that fits into concave process (uniaxial) | hinge joint |
| Rounded surface that fits into a shallow surface (uniaxial) | pivot joints |
| Oval condyle that fits into ellipisodal depression (biaxial) | condylar joint |
| Concave surface fits into concave (biaxial) | saddle joint |
| Ball shaped head that fits into a cuplike depression (multiaxial) | ball-and-socket joint |
