CLASSIFICATION OF BONES AND CARTILAGE Flashcards
Vobaulary
Functions of the skeletal system
- Support and protection
- Provide movement
- Store minerals like lipids and calcium
- Provide site for blood cell formation with the RB marrow
- Attachment for muscles
How many bones in body
206
Two divisions of the skeletal system
-Axial and Appendicular
what are examples of axial skeleton
brain and vertabrae
what are examples of appendicular skeleton
limbs and appendages
How many cartilages are found in the body
3
what are the 3 cartilages in the body
- Hyaline
- elastic
- Fibrocartilage
which cartilage in the body is most common
hyaline
found/support external ear
elastic
found in epiglottis
elastic
provide flexibility
elastic
provide strength and shock obsorption
fibrocartilage
what are the four types of hyaline carilage
Articular, Costal, Nasal and Respiratory
articular hyaline cartilage
Cover ends of bones at movable joints
Costal hyaline cartilage
Connects the ribs at sternum
Nasal hyaline cartilage
support external nose
Respiratory hyaline cartilage
found in larynx and other respiratory structures
what are the three types of fibcrocartilage found in the body
Intervertebral disc, Menisci and Pubic symphysis
Intervertebral disc
between vertebrae
Menisci
in knee joint
Pubic symphysis
in hip bones
How do we classify bones
long, short, flat or irregular
long bones
- longer than wide
- shaft with head at the end
- compact bone
example of long bone
femur, humerus, and phalanges
short bones
- Cube shaped
- spongy bone
