Joints Flashcards
continuous joints
movement is not possible
discontinuous joints
freely movable joints
amiphiarthrosis
slight movement between the bones
continuous joints usually features a ___ between the bones. Are classified according to two types:
- tissue
- Fibrous joint
- Cartilaginous joints
Joint? Consist of collagen fibers and other connective tissues between the bones, including interosseous membrane. The ___ are the sites of connective tissue that disappears when growth of the skull is completed and sutures fuse the bones. ____ corresponds to this joint between the teeth and alveoli of the jaws, and the periodontal tissue lies between tooth and bone. ___ between the vertebral arch contains elastic fibers, as well as collagen and other fibers that make it more flexible
fibrous joints
- sutures of the skull
- gomphosis
- ligamentum flavum
Joint? ___ inclue hyaline cartilage that lies between the bones, ____ between the epiphysis and diaphysis, joints between the 3 parts of the hip bone. The bone then firmly fuse to each other in a process called ____.
___, bones are covered by hyaline cartilage, but flat disc of fibrocartilage between them
cartilaginous joints
- primary cartilaginous joints
- epiphyseal
- synostosis
- Secondary cartilaginous joints
Joint? consist of articular surfaces (covered by hyaline structures), articular capsule, joint cavity filled with synovial fluid.
discontinuous
classification of synovial joints
- number of articular surfaces
- axes
- degree of freedom
- shape
synovial joints shapes:
hinge, pivot, plane joints, ellipsoidal joints, saddle and ball and socket joints.
lies between the head of the humerus and the glenoid cavity. It is a ball and socket joint with articular lip that expands the glenoid cavity to better fit the head of the humerus. movements are flexion, extension, abduction, adduction, medial rotation, lateral rotation and circumduction of the arm
shoulder joint
A plane joint, located between the acromion process of the spine of scapula and the acromial end of the clavicle
acromioclavicular joint
ball and socket joint, functions especially when shoulder joint is moving. lies between the sternal end of clavicle and sternum
sternoclavicular joint
synovial compound joint, capsule compromising 3 joints, humeroulnar, humeroradial, and proximal radioulnar joints. movements include flexion and extension of ___, as well as supination and pronation of the forearm.
elbow joint
ellipsoid type of synovial joint. formed by radius and articular disc, proximal row of carpal bones. Movements are abduction, adduction, flexion, dorsiflexion and circumduction
wrist (radiocarpal) joint
between the trapezium and metacarpal bone of the thumb is a
saddle joint
ball and socket in shape. movements are partly restricted due to collateral and other ligaments, but passive rotation is possible
metacarpophalangeal joints
hinge joints, with restricted movements involving the collateral and palmar ligaments. movements include flexion and extension
interphalangeal joints
ball and socket type synovial joint, lies between head of femur and acetabulum of __ bone. movements include flexion, abduction, adduction, rotation and circumduction
hip joint
hinge type of synovial joint. ACL prevent backward sliding of femur and PCL prevent forward sliding of femur. Movements include of ___ joints, flexion and extension, femur rolling and gliding over menisci
knee joint
provided by tibia, fibula, and the talus. monoaxial hinge joint. range of motion up to 70 degree, including plantar flexion and dorsiflexion
ankle joint
other joints of the foot include:
subtalar and talocalcaneonavicular joints
___ joints have restricted movements; ___ joints are ball and socket joint, ____ joints are hinge joints
intertarsal, metatarsophalangeal, interphalangeal
