what is the appendicular skeleton?

Limbs

what are long bones?

they are only found in the appendicular skeleton (limbs). they are predominantly involved in movement rather then protection and are longer then they are wide

what are short bones?

they are only found in the appendicular skeleton (limbs). they are typically found in the carpal and tarsal regions. they are typically wide as they are long

-radius

-ulna

-phalanges (fingers and toes)

-metacarpals (hand bones and foot bones)

-fibula

-tibia

-femur

what are some examples of short bones?

carpals and tarsals

what are some examples of flat bones?

ribs and the cranium

what are some examples of sesamoid bones?

a great example is the patella (kneecap)

what are some irregular bones?

examples include the os coxae (pelvis) or the vertebra (bones that make up the vertebra column)
