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
