9.3 - Cartilaginous joints

give 3 examples of symphyses

1. public symphysis 2. manubrium and body of sternum 3. intervertebral disc

3 types of cartilaginous joints

1. synchondroses 2. symphyses 3. epiphyseal cartilage

when bone stops growing at epiphyseal growth plate, what replaces the hyaline cartilage?

bone

the bones in a symphyses are connected by a

broad, flat disc of fibrocartilage

epiphyseal cartilage is a type of

cartilaginous joint

symphyses is a type of

cartilaginous joint

synchondroses is a type of

cartilaginous joint

epiphyseal cartage are growth

centers during endochondral bone formation

give an example of epiphyseal cartilage

epiphyseal growth plate

the epiphyseal plate connects the

epiphyses to diaphysis

the intervertebral discs are made out of

fibrocartilage

a synostosis also occurs in the

frontal bones during development when 2 halves fuse into 1 by age 6

synchondroses is made out of

hyaline cartilage

symphyses is made out of

hyaline cartilage at the ends of articulating bones

articulating bones in cartilaginous joint are tightly connected by either

hyaline cartilage or fibrocartilage

the intervertebral discs provide

limited range of motion and shock absorption between vertebral bodies

cartilaginous joints allow what kind of movement?

little or no movement (amphiarthosis or synarthrosis)

all symphyses occur along the

midline of the body

pubic symphysis is slightly

movable to allow expansion of pelvic girdle during labor

epiphyseal cartilage is not a joint associated with

movement

describe movement of synchondroses

slightly movable to immovable joint

cartilaginous joints contain

solid CT

give example of synchondroses

synchondrosis (singular) between 1st rib and manubrium

synchondroses is NOT the same thing as

syndesmoses

epiphyseal cartilage becomes a

synostosis, which is a bony joint that occurs during complete fusion of 2 bones

since the CT of cartilaginous joints in solid, articulating bones are connected

tightly

irregular fusion of the 2 halves of the frontal bone by age 6 leads to a

visible frontal line
