Hyaline cartilage

frosted glass to provide support with flexibility (most abundant cartilage)

Fibro cartilage

great for strength, shows up in places with a lot of pressure to absorb shock, shows up in places we need to stretch (ex. reproduction-stretches the pubic region)

Elastic cartilage

Only shows up in two places of the human body-ear lobes and epiglottis

Functions of bones:

Support, protection, movement, mineral and growth storage, blood cell formation, triglyceride storage, hormone production

How many bones in the human body?

206

The bones shape consists of:

Long, short, flat, and irregular

The bone location consists of:

Axial-long axis of body, skull, vertebral column, rib cage

Appendicular-bones of upper and lower limbs, girdles attaching limbs to axial skeleton

Long bones

They are longer than they are wide and it has a shaft and two ends ex. forearm

Short bones

Shows up in the wrist, hands, and feet

Flat bones

They are thin, flat, and often curbed (ribs)

Irregular Bones

They would be vertabrate, strongely shaped (pelvic area)

Non displaced fracture:

the end of the bone keeps its normal position, or in general the bone keeps its normal position.

Displaced fracture:

the end of the bone would not be in its normal position

Complete fracture

The bone is broken all the way through

Incomplete fracture

The bone is not broken all the way through, its broken partially

Compound fracture

The bone penetrated through the skin, its visible to the human eye

Simple fracture

The bone did not penetrate through the skin
