Flashcards in Chapter 9: Skeletal System: Articulations Deck (132)
bone with rounded surface fits into a ring formed by a ligament and another bone
i.e. atlantoaxial joint
oval articular surface on one bone closely interfaces with a depressed oval surface on another bone
i.e. MP (metacarpophalangeal or metatarsophalangeal) joints
saddle-shaped articular surface on one bone closely interfaces with a saddle shaped surface on another bone
i.e. articulation between carpal and first metacarpal bone
round head of one bone rests within cup-shaped depression in another bone
ball and socket joint
i.e. glenohumeral (shoulder) joint, hip joint
Ball and Socket
The most stable joint
The most unstable joint
A ____ resembles a "peg in a socket".
The only _____ in the human body are the articulations of the roots of individual teeth with the alveolar processes (sockets) of the mandible and the maxillae.
A tooth is held firmly in place by fibrous _____ membranes.
____ have distinct, interlocking, usually irregular edges that both increase their strength and decrease the number of fractures at these articulations.
Sutures permit the skull to ___ as the brain increases in size during childhood.
In an older adult, the suture becomes _____, fusing the skull bones together.
When the bones have completely fused across the suture line, these obliterated sutures become _____.
The shafts of the two articulating bones are bound by a broad ligamentous sheet called an ______.
The interosseous membrane provides a ____ where the radius and ulna (or the tibia and fibula) can move against one another.
The cartilage found between the articulating bones is either ____ or _____.
hyaline cartilage or fibrocartilage
The hyaline cartilage of epiphyseal plates in children forms ____ that bind the epiphyses and diaphysis of long bones.
When the hyaline cartilage stops growing, bone replaces the _____ and a sychondrosis no longer exists.
The ____ synchondrosis found between the body of the sphenoid and the basilar part of the occipital bone.
The spheno-occipital synchodrosis typically fuses between ____ of age, making it a useful tool for assessing the age of the skull.
18 to 25 years of age
the joint between each bony rib and its respective costal cartilage, is a synchondrosis
