week 3 cartilage and joints Flashcards
cartilage definition
semi-rigid connective tissue
3 types of cartilage
example for place for each
hyaline, elastic and fibrocartilage
elastic=ear
hyaline=ribs, nose
fibrocartilage= intervertebral discs
cartilage is highly vascular
no its not, its avascular you dimwit.
Cartilage does not contain blood vessels (avascular) or nerves (aneural)
Which cartilage type is found in an epiphyseal plate?
hyaline
most common type of cartilage
hyaline
Which cartilage type covers the end of a bone in a synovial joint?
hyaline
which type of cartilage is also known as articular cartilage
hyaline
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?
cartilage is avascular, bone isn’t.
joints are classified by what, and what are the three types
by the type of tissue present
cartilaginous- primary and secondary aka symphses
synovial plane
fibrous
example of synovial plane joint
between the articular joints between superior and inferior articular processes
example of fibrous joint
in the skull
example of cartilaginous joint
eg secondary cartilaginous/fibrocartilaginous/symphyses joint between intervertebral bodies
MRI bones are white true or false
no MRI bones are black
do ventral root ganglion exist
no just dorsal root ganglion
which joint type is the most mobile
synovial joint, eg knee joint for femur and tibia
which joint type is the least mobile
fibrous joint eg in the skull
Give the three main structural characteristics of a typical synovial joint:
synovial fluid, within synovial membrane, within articular capsule
what does each cartilage look like in terms of histology?
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
which type of cartilage has a perichondrium
perichondrium layer for hyaline (hyaline is the weakest type of cartilage)
what does spongy bone look like, histology
cow print
Other than in the epiphyseal plate, where else is hyaline cartilage found in a long bone?
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.
What tissue/s is found in the marrow (medullary) cavity? What is the function of the medullary cavity?
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
epiphyseal growth plate is made of what tissue
connective tissue, hyaline cartilage
what type of joint is found in the epiphyseal growth plate
primary cartilaginous
