anatomy joints

The study of joints or articulations

arthrology

\####what kind of joint is one in which the bones are held together by collagenous fibers

fibrous joint

\####when two bones fuse into a single bone, this union is called

synostosis

\####the teeth are held in the jaw by what specific kind of joint?

gomphoses

\####what kind of joint is slightly movable and is held together by fibrous connective tissue?

syndesmosis

\####in terms of structural composition, bones that are held together by cartilage are also known as

synchondroses

\####the epipyseal plate is a cartilaginous joint. It is also called a(n)

synchondroses

\####what is the name of a joint that is held together by a joint capsule?

synovial joint

\####synovial fluid is secreted by what structure?

synovial membrane

\####a skull suture is what kind of joint, in terms of movement?

synarthrotic joint

\####Which of the following joints has the greatest range of movement?

a. gomphosis

b. suture

c. synchondrosis

d. hinge

d. hinge

\####in which of these joints would you find a meniscus?

a. cartilaginous

b.fibrous

c.synovial

synovial

\####what is the function fo the meniscus in the knee?

provides cushion between femur and tibia

\####what is the function of the labrum in the shoulder joint?

to deepen the glenoid fossa

\####the joint between the trapezium and the first metacarpal is what kind of joint?

saddle

\####a class of joint with great movement is a(n)

diarthoses

\####the joint between the scapula and the humerus is what type of joint?

ball and socket

\####what kind of joint is located at the wrist (between the radius and the scaphoid bones)

condyloid joint

\####synarthroses

immovable joints

\####amphiarthroses

slightly movable joints

\####diarthroses/synovial

freely movable joints

\####how are joints classified structurally?

- synovial

-bony

-fibrous

-cartilaginous

\####what are the four major types of synarthroses

-suture

-gomphosis

-synchondrosis

-synostosis

\####suture

skull bones bound together by dense connective tissue

\####gomphosis

teeth bound to bony sockets by periodontal ligaments

\####synchondrosis

two bones joined by a rigid cartilaginous bridge

\####synostosis

two bones completely fused

\####two major types of amphiarthroses

- syndesmosis

- symphysis

\####syndesmosis

bones connected by a ligament

\####symphysis

bones connected by fibrocartilage

\####joint capsule (articular capsule)

encloses cavity and contains synovial fluid

\####functions of synovial fluid

-lubrication

-nutrient distribution

-shock absorpotion

\####articular cartilage

covers the surfaces of bones where they come together to form joints

\####synovial fluid

joint-lubricating fluid secreted by the synovial membrane

\####accessory synovial structures

-menisci

-fat pads

-accessory ligaments

-tendons

-bursae

\####dislocation

occurs when articulating surfaces are forced out of position

\####possible types of articular motion

-linear motion (plane or gliding)

-angular motion

-rotation

\####plane(gliding) joint

permit limited movement, generally in a single plane

\####joints that move in a single plane

monoaxial

\####joints that move in two planes

biaxial

\####joints that move in three planes

monoaxial

\####hinge joints

monoaxial joints that permit only angular movement in one plane

\####condylar joints

biaxial joints with an oval articular face that nestles within a depression in the opposing articular surface

\####saddle joints

biaxial joints wit articular faces that are concave on one axis and convex on the other
