What is axial skeleton?
Found is centre of body and protects vital organs.
What is the appendicular skeleton?
Mainly used for movement and support of bones
Bones in head
Cranium
Bones in axial skeleton
Vertebrae
Cranium
Sternum
Ribs
Sacrum- near pelvis
Coccyx- near pelvis
Bones near shoulder
Scapula- flaps at back of shoulder
Clavicle
Bones in upper arm
Humerus
Bones in lower arm
Radius- thumb side
Ulna
Bones in wrist
Carpals
Bones in hand
Metacarpals
phalanges
Bones under ribs
Pelvis
Ilium
Ischium
Pubis
Bones in upper leg
Femur
Bones in lower leg
Tibia-thicker bone
Fibula-thinner bone
Bones in ankle
tarsals
tallus
Bones in foot
metatarsals
Phalanges
Six functions of skeleton
Shape
support
Movement
Protection
Production of blood cells
Mineral storage
Shape
Bones give us shape for example, vertebrae helps keep body upright
Support
Give body posture
Holds body upright
Gives stability/ structure
Movement
Skeleton had joints- provide point of attachment for muscles
Tendons- pull on bones
Ligaments allow movement
Protection
Prevents injury to vital organs
Surrounds vital organs
Production of blood cells
Where red and white blood cells are created - bone marrow
Red blood cells- oxygen
White blood cells- fight pathogens
Mineral storage
Calcium/iron stored in bones- long bones e.g femur
Minerals held in bone marrow
Long Bone
-Bones that are longer than they are wider
Function - production of blood cells, movement, shape and mineral storage e.g femur
Short bone
Bones that are short and almost cubic shape
Function- Movement e.g carpals
Flat bone
Bones that are flatter than they are wider
Function- protection- cranium, ribs
Irregular bones
Bones that do not fit into any other category
Function- protection and movement- Vertebrae
Sesamoid bone
Bones that are similar to a short bone but they are with a tendon
function- movement- patella
Joint classification
Fixed joint
Slightly moveable joint
Freely moveable joint
Fixed joint
allows no movement and is important for skeleton to grow and delveop
E.g. cranium- grows and develops to accommodate brain
