D3:Location of Skeletal bones Flashcards
what is the axial skeleton?
-central core of the body
what bones are a part of the axial skeleton?
-cranium
-vertebrae
-sternum
-ribs
function of the axial skeleton?
-to provide a core to which other limbs can attach to
-protects vital organs and ensures the body survives
what is the appendicular skeleton?
outer skeleton which consists of parts hanging off the axial skeleton-peripheral bones
what bones make up the appendicular skeleton?
-shoulder girdles-scapula,clavicle,pelvic girdle and upper and lower limbs
what is the function of the appendicular skeleton?
provide movement and stability
5 types of bones?
-long
-short
-flat
-irregular
-sesamoid
structure of long bones?
-has a shaft and is longer than it is wide
function of long bones?
lever and movement
examples of long bones?
-radius
-ulna
-humerus
-femur
-tibia
structure of flat bones?
2 layers of compact bone with a middle of cancellous bone
function of flat bones?
to protect
examples of flat bones?
-ilium
-cranium
-sternum
-ribs
structure of short bones?
shaped roughly as a cube and mostly cancellous(spongey) bone
function of short bones?
balance and weight bearing
examples of short bones?
-carpels
-tarsels
structure of sesamoid bones?
small bone that is found between muscle of tendon near joint surfaces
function if sesamoid bones?
reduces friction and protects muscle tendon
examples of sesamoid bones?
-patella
structure of irregular bones?
-non uniform shape and structure
function of irregular bones?
provides protection of nerves and support for pharynx and trachea
examples of irregular bone?
vertebrae column
