Larynx

Question 1

Fibrous

Answer 1

Inelastic; fiber glass

Intervertebral disks

Question 2

Elastic

Answer 2

More elastic fibers, more flexible, yellowish

Ears

Question 3

Synarthrodial joints

Answer 3

Not very moveable
Ex:chin, skull
Not intended to move

Question 4

Amphiarthrodial joint

Answer 4

Limited motion
Ex: vertebrae
Slightly moveable

Question 5

Synovial joints

Answer 5

Freely moveable, most common joint

Question 6

Plane or glide joint

Answer 6

Concave surface with concave surface (sliding)

Question 7

Ginglymus

Answer 7

Hinge joint, large range of motion in 1 plane

Knee

Question 8

Pivot

Answer 8

Small projection of one bone thru another for good range of motion

Axis and atlas

Question 9

Condyloid

Answer 9

Oval surface, convexity to fit inside-no rotation

Jaw

Question 10

Saddle

Answer 10

Greater range of motion similar to condyloid joint with more movement

Thumb

Question 11

Ball and socket

Answer 11

Most freely moveable, in every plane including rotation

Shoulder, hips

Question 12

Hyoid bone

Answer 12

Only free floating bone in body, unpaired “u” shapes

Question 13

Epiglottis

Answer 13

Umpired, sits behind hyoid bone (elastic cartilage)

Question 14

Thyroid cartilage

Answer 14

Unpaired, “Adams apple” midline (largest) hyaline cart. (Greater/ lesser horns)

Question 15

Cricoid cartilage

Answer 15

Unpaired, midline, touches horns of thyroid cartilage. Sits on top of trachea

Question 16

2 arytenoids

Answer 16

Sits on top of cricoid, makes saddle joint. Open- close vocal folds

Question 17

2 corniculate

Answer 17

Sits on top of arytenoids (look like teeth)

Question 18

2 cuneiform

Answer 18

Floating, contained in aryepiglottic folds

Question 19

Cricothyroid joint

Answer 19

Pivot
Flat facets
Slightly concave/ complex
Slightly rotational - lengthens vocal folds

Question 20

Cricoarytenoid joint

Answer 20

Saddle
Oval facets
Rocking gliding movement- limited by tendinitis encapsulation

Question 21

Intrinsic membranes and ligaments

Answer 21

Affects movements of the cartilages
Elastic membrane that line all of the larynx
Membrane: connective tissue in the inside of the larynx

Question 22

Extrinsic membranes

Answer 22

Wrapping the outside cartilages
Major gap fillers
Do not govern movement
Thickened in middle

Question 23

Supra glottal

Answer 23

Above the glottis

Question 24

Vestibule

Answer 24

Open space at top of larynx, near epiglottis down to cuneiform

Question 25

Ventricle

Answer 25

Right under ventricular folds. Space between true/ false folds

Question 26

Subglottal

Answer 26

Below the glottis- bottom border of cricoid

Question 27

Anterior commissure

Answer 27

Where TVF attach at front of cartilages

Question 28

Posterior commissure

Answer 28

Arched space in back

Question 29

Glottis

Answer 29

Open space between TVF

Question 30

Extrinsic muscles of the larynx

Answer 30

Elevate it depress the larynx (move or fix larynx )

Question 31

Suprahyoid

Answer 31

Muscles above hyoid bone

Elevators

Question 32

Digastricus

Answer 32

“2 bellies” anterior/ posterior. Belly moves hyoid bone up and slightly forward

Question 33

Mylohyoid

Answer 33

Forms floor of mouth- wide origin, deep ,helps drop jaw

Question 34

Stylohyoid

Answer 34

Long/slender. Run along posterior belly
Laterally
Pulls back and up

Question 35

Geniohyoid

Answer 35

Arises medial of mandible- anterior body of hyoid bone

Question 36

Hyaline Cartilage

Answer 36

Glassy, rigid, found at end of bones. Attach ribs to sternum calcify when older
