week 3 cartilage and joints

Question 1

cartilage definition

Answer 1

semi-rigid connective tissue

Question 2

3 types of cartilage
example for place for each

Answer 2

hyaline, elastic and fibrocartilage

elastic=ear
hyaline=ribs, nose
fibrocartilage= intervertebral discs

Question 3

cartilage is highly vascular

Answer 3

no its not, its avascular you dimwit.
Cartilage does not contain blood vessels (avascular) or nerves (aneural)

Question 4

Which cartilage type is found in an epiphyseal plate?

Answer 4

hyaline

Question 5

most common type of cartilage

Answer 5

hyaline

Question 6

Which cartilage type covers the end of a bone in a synovial joint?

Answer 6

hyaline

Question 7

which type of cartilage is also known as articular cartilage

Answer 7

hyaline

Question 8

What essential vascular difference exists between bone and cartilage that allows the bone to regenerate relatively quickly, whereas regeneration is very much slower in cartilage?

Answer 8

cartilage is avascular, bone isn’t.

Question 9

joints are classified by what, and what are the three types

Answer 9

by the type of tissue present
cartilaginous- primary and secondary aka symphses
synovial plane
fibrous

Question 10

example of synovial plane joint

Answer 10

between the articular joints between superior and inferior articular processes

Question 11

example of fibrous joint

Answer 11

in the skull

Question 12

example of cartilaginous joint

Answer 12

eg secondary cartilaginous/fibrocartilaginous/symphyses joint between intervertebral bodies

Question 13

MRI bones are white true or false

Answer 13

no MRI bones are black

Question 14

do ventral root ganglion exist

Answer 14

no just dorsal root ganglion

Question 15

which joint type is the most mobile

Answer 15

synovial joint, eg knee joint for femur and tibia

Question 16

which joint type is the least mobile

Answer 16

fibrous joint eg in the skull

Question 17

Give the three main structural characteristics of a typical synovial joint:

Answer 17

synovial fluid, within synovial membrane, within articular capsule

Question 18

what does each cartilage look like in terms of histology?

Answer 18

hyaline: kinda lots of space between them, like polka dots
fibrocartilage has got densely packed fibres with organised cells in rows, whilst elastic cartilage has visible messy elastin cartilage

Question 19

which type of cartilage has a perichondrium

Answer 19

perichondrium layer for hyaline (hyaline is the weakest type of cartilage)

Question 20

what does spongy bone look like, histology

Answer 20

cow print

Question 21

Other than in the epiphyseal plate, where else is hyaline cartilage found in a long bone?

Answer 21

You can also find hyaline cartilage at the end of the long bone.
Hyaline cartilage at the ends of your bones is sometimes referred to as articular cartilage.

Question 22

What tissue/s is found in the marrow (medullary) cavity? What is the function of the medullary cavity?

Answer 22

red and yellow bone marrow aka spongy bone is found in the medullary cavity. The function of the medullary cavity is:
yellow (adipose) energy reserves
red marrow, blood cell production

TBM

Question 23

epiphyseal growth plate is made of what tissue

Answer 23

connective tissue, hyaline cartilage

Question 24

what type of joint is found in the epiphyseal growth plate

Answer 24

primary cartilaginous

Question 25

cartilaginous joint definition

Question 26

what type of joint is the knee joint

Answer 26

synovial hinge

Which of the following joints is ossified in adults?

a. Primary cartilaginous
b. Secondary cartilaginous
c. Fibrous
d. Synovial
e. Suture

Answer 27

primary cartilaginous

Question 28

In which of the following joint type the bones are united by cartilage?

Select one:
a. Plane Synovial
b. Hinge
c. Fibrous
d. Condyloid
e. Symphysis

Answer 28
