1

joints are named

according to the bones or portions of bones that are united at the joint

2

joints are classified by

major connective tissue type that binds
whether or not there is a fluid-filled joint capsule
function

3

_____consist of two bones that are united by fibrous connective tissue, have no joint cavity, and exhibit little or no movement

fibrous joints

4

fibrous joints are classified by

basis of sutures, syndesmoses, or gomphoses

5

_____ are seams between the bones of the skull, and some sutures may be completely immovable.

suture

6

_____ results when 2 bones grow together across a joint to form a single bone

synostosis

7

a ______ is a type of fibrous joint in which the bones are further apart than in a suture and are joined by ligaments

syndesmosis

8

_____ are specialized joints consisting of pegs that fit into sockets and that are held in place by fine bundles of regular collagenous connective tissue

gomphoses

9

__________ unite two bones by means of either hyaline cartilage or fibrocartilage.

cartilaginous joints

10

__________ consists of two bones joined by hyaline cartilage

synchondrosis

11

________ consists of fibrocartilage uniting two bones.

symphisis

12

______ those containing synovial fluid, allow considerable movement between articulating bones

synovial joints

13

the articular surfaces of bones within synovial joints are covered with a thin layer of hyaline cartilage called

articular cartilage

14

additional fibrocartilage _________ are associated with several synovial joints such as the knees and the TMJ. They provide extra strength and support to the joint

articular disks

15

asynovial joint is enclosed by ________ which helps to hold the bones together while allowing for movement.

joint capsule

16

the joint capsule has an outer layer called

outer fibrous capsule

17

the joint capsule has an inner layer called

inner synovial membrane
