Cartilage and bone tissue Flashcards
These form from stress as tendons repeatedly move access a joint
Sesamoid bones
What is the biggest sesamoid bone in our bodies
patella
What produces chartilage
chondroblasts
what helps maintain cartilage matrix
mature condrocyte
the 3 functions of cartilage
- supporting soft tissue
- provides a gliding surface at articulation where two bones meet
- serve as a model for later bone development
Hyaline cartilage and where it is found
model cartilage for later developing bone.
Contributes to structures of respiratory tract, fetal skeleton, growth plates and joints
Fibrocartilage and where it is found
flexible and capable of withstanding considerable pressure
Intervertebral disks and pubic symphysis
Where is elastic cartilage found
ear
Functions of bones
allow us to move
Protect delicate organs
hematopoeisis
What is hematopoeisiss
making of blood cells
Where does hematopoeisis occur
active red marrow of the sternum, vertebrae, pelvis and proximal ends of bones of thigh and upper arm
What stimulates hematopoeisis
erythropoietin
where is the best place to do a sternal bone marrow biopsy
posterior portion of the ilium
what is the shaft of a long bone called
diaphysis
what is located inside the diaphysis
yellow marrow
What are the ends of the long bone called
epiphysis
what is located inside the epiphysis
red marrow
periosteum
covers the outside of bones, generally merges into tendons
medulary cavity
inside diaphysis of bone, usually contains yellow marrow
endosteum
lining on inside of bone
Nutrient foramen
allows passage of blood vessels to keep bone alive
allows long bones to increase in length
epiphyseal growth plate
What stimulates the epiphyseal growth plate and where is it produced
Human growth hormone
Pituitary gland
When the epiphyseal growth plate ossifies what is it replaced with
epiphyseal line
