chapter 3 (articular system)

Question 1

joint

Answer 1

connection of 2 bones

Question 2

functions of joint

Answer 2

allow motion, absorb force, provide stability

Question 3

Fibrous Joint

Answer 3

Thin layer of fibrous periosteum between the two bones

Question 4

3 types of fibrous joint

Answer 4

synarthrosis, syndesmosis, gomphosis

Question 5

synarthrodial (suture), motion?

Answer 5

thin layer, provides support, skull. no motion

Question 6

syndesmosis (ligamentous)

Answer 6

plenty of fibrous tissue, small amount of twisting(radius, ulna, tibia, fibula)

Question 7

gomphosis

Answer 7

bolting together ( tooth and dental socket

Question 8

Cartilaginous = Amphiarthrodial

Answer 8

allow small amount of motion, hyaline cartilage

Question 9

Synovial = Diarthrodial ex.

Answer 9

allows free motion, cavity filled with synovial fluid. hip, elbow, knee

Question 10

join structure of synovial fluid components

Answer 10

bones, ligaments, synovial fluid, cartilage, muscles, bursae

Question 11

bones

Answer 11

two articulating

Question 12

ligaments

Answer 12

holds bones together. fibrous connective tissue

Question 13

capsule

Answer 13

surrounds and incase the joint, protect bone

Question 14

Synovial Fluid

Answer 14

thick-white fluid, lubricate, provide shock absorption

Question 15

Cartilage

Answer 15

dense fibrous tissue, hold great tension

Question 16

types of cartilage tissue

Answer 16

hyaline, fibrocartilage, elastic

Question 17

Hyaline = Articular Cartilage

Answer 17

ends of opposing bones

Question 18

Fibrocartilage

Answer 18

shock absorption, holds great weight

Question 19

Elastic Cartilage

Answer 19

certain amount of motion

Question 20

muscles

Answer 20

provide contractile force that cause joints to move
