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 |
