Joints Flashcards
What joint lacks a joint cavity and is held together by a fibrous connective tissue?
Fibrous joints
Which of the following types of joints do NOT have a synovial cavity?
- Fibrous joints
2. Cartilaginous joints
Which functional class of joints contains joints that are freely movable?
Diarthrosis
Which of the following is a type of fibrous joint composed of a thin layer of dense irregular fibrous connective tissue found between the bones of the skull?
Suture
A suture joint fits into which functional joint classification?
synarthrosis.
The epiphyseal plate in a long bone is an example of which type of joint?
Synchondrosis
Which of the following is NOT a common characteristic
of synovial joints?
a) Contain a joint cavity
b) Are freely moveable
c) Articulating bones are covered with hyaline cartilage
d) Include elastic cartilage
e) Have ligaments holding the joint together
d) Include elastic cartilage
What structures are used to reduce friction in joints?
- Bursae
2. Synovial fluid
Which type of motion results from relatively flat bone surfaces moving back and forth and from side to side with respect to one another?
Gliding
Moving the humerus laterally at the shoulder joint is an example of which type of movement?
Abduction
Which type of movement involves a continuous sequence of flexion, abduction, extension, and adduction resulting in a distal body part moving in a circle?
Circumduction
Which special movement occurs when you bend your foot at the ankle in the direction of the foot’s superior surface as would occur when you balance on your heels?
Dorsiflextion
Which special movement involves moving your thumb across the palm to touch the tips of the fingers on the same hand?
Opposition
Which of the following is NOT a structural category of synovial joints?
a) Planar
b) Hinge
c) Condyloid
d) Suture
e) Saddle
Suture
In which type of synovial joint does a rounded or pointed surface on one bone articulate with a ring formed partly by another bone and partly by a ligament?
Pivot joint
A condyloid joint
a) is also called an ellipsoidal joint.
b) is considered to be biaxial.
c) allows both flexion–extension and abduction–adduction of the joint.
d) can be found in the wrist.
what is a syndesmosis joint?
A syndesmosis is defined as a fibrous joint in which two adjacent bones are linked by a strong membrane or ligaments.
What is a gomphosis joint?
A gomphosis is a fibrous mobile peg-and-socket joint. The roots of the teeth (the pegs) fit into their sockets in the mandible and maxilla and are the only examples of this type of joint.
What joint is found at the elbow and its movements?
Hinge joint
This joint allows uni-direction movement of flexion and extension only.
What joint is found at the thumb?
Saddle
The articular surfaces are concave and convex and allow a wide range of movements. The 1st carpometacarpal joints are examples.
What is a plane joint, with examples?
The articular surfaces are flat and allow gliding movements. Other examples are the intercarpal and intertarsal joints.
What are Condylar / Ellipsoid and where they found
Otherwise known as condyloid (knuckle-like, not to be mistaken for Condylar). They resemble saddle joints but have less movement.
Between metacarpals and phalanges
Sutures, syndesmoses and gomphoses are three types of which joint classification?
Fibrous Joints
Which type of joint are the joints between the vertebral bodies?
Symphysis
This is a cartilaginous joint. The ends of the bone are covered with hyaline cartilage and are joined by a disc of fibrocartilage. Movements are variable.
