Ch 3 Articular System

Question 0

3 types of fibrous joints

Answer 0

Synarthrosis, syndesmosis, gomphosis

Question 1

3 types of joints

Answer 1

Fibrous
Cartilaginous
Synovial

Question 2

Fibrous joint

Answer 2

Thin layer of fibrous periosteum between two bones

Ex:sutures in skull

Question 3

Synarthrosis

Answer 3

Suture joint

Question 4

Syndesmosis

Answer 4

Ligamentous joint. Great deal of fibrous tissue holding the joints together
Ex: interosseous membrane

Question 5

Cartilaginous joint

Amphiarthrodial joint

Answer 5

Either hyaline cartilage or fibrous cartilage between the two bones.
Ex: vertebral joints

Question 6

Synovial joint

Diarthrodial joint

Answer 6

No direct union between the bones. Instead, there is a capsule filled with synovial fluid.

Question 7

Classifications of diarthrodial joints

Answer 7

Non axial, uni axial, biaxial, triaxial

Question 8

Non axial joint

Answer 8

Irregular plane
Gliding
Ex: intercarpals

Question 9

Uniaxial

Answer 9

Angular motion in one plane around one access
Hinge joint
Ex: elbow

Question 10

Biaxial joint

Answer 10

Occurs in two different directions

Ex: the wrist

Question 11

Triaxial joint

Answer 11

Has motion in all 3 axis
Ball and socket
Ex: shoulder

Question 12

Ligaments

Answer 12

Bone to bone

Question 13

Tendons

Answer 13

Muscle to bone

Question 14

Synovial membrane

Answer 14

Thick vascular connective tissue that secretes synovial fluid

Question 15

Hyaline cartilage

Articular cartilage

Answer 15

Covers the ends of opposing bones, provides a smooth surface for synovial joints.
Lacks its own blood and nerve supply so it must get its nutrition from synovial fluid…. It can NOT repair itself from damage.

Question 16

Fibrocartilage

Answer 16

Acts as shock absorber

Ex: meniscus

Question 17

Labrum

Answer 17

Is the shoulder fibrocartilage

Deepens the glenoid fossa

Question 18

Elastic cartilage

Answer 18

Help maintain a structures shape

Ex : ear

Question 19

Tendon sheaths

Answer 19

Surround the tendon when it is subject to pressure of friction

Question 20

Aponeurosis

Answer 20

Broad, flat tendinitis sheet

Question 21

Bursae

Answer 21

Small, padlike sacs found around most joints to reduce friction

Question 22

Sagittal, frontal, transverse plane

Answer 22

Define and explain

Question 23

Sagittal plane is what axis
Frontal?
Transverse?

Answer 23

Frontal
Sagittal
Vertical

Question 24

Dislocation

Answer 24

Complete separation of two articular surfaces of a joint.

Question 25

Subluxation

Answer 25

Partial dislocation of a joint, usually occurs over time

Question 26

Osteoarthritis

Answer 26

Caused by the breakdown and loss of cartilage

Question 27

Sprains

Answer 27

Teeing of ligament fibers

Question 28

Strain

Answer 28

Over stretching of muscle fibersm

Question 29

Synovitis

Answer 29

Inflammation of synovial membrane

Question 30

Tenosynivitis

Answer 30

Inflammation of the tendon sheath

Question 31

Give an example f a synarthrodial joint in the axial skeleton

Answer 31

Suture of the skull
