Flashcards in Chapter 9: Skeletal System: Articulations Deck (132)
the place of contact between bones, between bone and cartilage, or between bones and teeth.
joint or articulation
Bones are said to _____ with each other at a joint.
The scientific study of joints is called ___.
Joints are classified by both their structural characteristics and the ____ they allow.
Joints are categorized structurally on the basis of whether a space occurs between the _____ and the type of connective tissue that binds the articulating surfaces of the bones.
has no joint cavity and occurs where bones are held together by dense regular (fibrous) connective tissue.
has no joint cavity and occurs where bones are joined by cartilage
a fluid-filled joint cavity that separates the articulating surfaces of the bones. the articulating surfaces are enclosed within a connective tissue capsule, and the bones are attached to each other by various ligaments.
Joints are classified into 3 different structural categories
Joints are classified into 3 different functional categories based on the extent of the movement that permit
_______ is an immobile joint. two types of fibrous joints and one type of cartilaginous joint are _______.
An _____ is a slightly mobile joint. One type of fibrous joint and one type of cartilaginous joint are _____.
A ________ is a freely mobile joint.
All synovial joints are ____.
The _____ of each joint determines both its mobility and its stability.
When the mobility of a joint increases, its stability ______.
If a joint is immobile, it has ____ stability.
Structural characteristics of a _____ joint include dense regular connective tissue that holds together the ends of bones and bone parts; no joint cavity.
Structural characteristics of a ____ joint include a pad of cartilage that is wedged between the ends of bones; no joint cavity.
Structural characteristics of ____ joint include the ends of bones covered with articular cartilage; joint cavity separates the articulating bones; joint enclosed by an articular capsule, lined by a synovial membrane; contain synovial fluid.
Three structural categories of fibrous joints.
Two structural categories of cartilaginous joints.
Three structural categories of synovial joints.
Ball and socket joint
periodontal membranes hold tooth to bony jaw
i.e. tooth to jaw
dense regular connective tissue connects skull bones
ie. Lamboid suture (connects occipital and parietal bones)
dense regular connective tissue fibers between bones
i.e. articulation between radius and ulna, and between tibia and fibula
hyaline cartilage between bones
i.e. epiphyseal plates in growing bones; costochondral joints
fibrocartilage pad between bones
i.e. pubic symphysis; intervertebral disc articulations
flattened or slightly curved faces slide across one another
i.e. intercarpal joints, intertarsal joints
