axial bones - provide
protection
on vital
organs
, stability,
attachment
for muscles
appendicular
bones - provide
support
and
mobility
axial
bones - cranium, ribs, sternum and vertebral column
support
function - provides support for
organs
, something for them to attachment and suspend to, axial skeleton is the basis for all movement
shape
- gives you shape eg shape of your face and how tall you are
protection
- protects vital organs by
absorbing
impact
used by flat bones
movement - skeletal system moved by
formation
of bones and joints and attatchments to
muscular system
via
tendons
fixed joints
allow
no movement
, they allow us to
grow
and develop
cartilaginous joints
allow
small
movement
synovial
bones are freely
moveable
and theres 6 types
fixed
joint examples
cranium
and
pelvis
cartilaginous
joint examples
ribs
,
vertebrae
, sternum
synovial
examples hip,
knee
, ankle
blood
cell
production contains
bone marrow
where
red
blood cells and white
blood
cells
are made
mineral storage
iron, calcium and
phosphorus
are stored in bones, uses for functions such as
nerve
transmissions
,
haemoglobin
and
metabolism
long
bones are longer than it is
wide
, provides
movement
, mineral storage,
support
, blood
cell production
examples of long bones are
femur
,
tibia
,
humerus
, metacarpals, metatarsals
short bones
are as wide as they are long, provides support, fine movement and
weight bearing
short bones examples are
carpals
and
tarsals
flat bones
are flat plates of bone, provides
protection.
base for all muscular attachments and blood cell production
flat bone
examples are pelvis, sternum, scapula, cranium, ribs
sesamoid bones
are short and irregular embedded in a
tendon
, provides protection and support
sesamoid
bone examples are the
patella
irregular
bone has an odd shape provides
movement
,
protection
and support
irregular
bone examples are
vertebrae
and mandible
ball and
socket
examples are
hip
and
shoulder
ball and socket movements are
flexion
,
extension
,
abduction
,
adduction
,
circumduction
and
rotation
hinge
movements are
flexion
and
extension
hinge examples are
knee
and
elbow
condyloid movements are
flexion
,
extension
,
abduction
,
adduction
and
rotation
condyloid
examples are
wrist
pivot
movements are
rotation
pivot
examples are
neck
and
radio-ulna
saddle
movements are
flexion
,
extension
,
abduction
and
adduction
saddle examples are
thumb
gliding
movements are
glide
gliding
examples are
vertebrae
articular
cartilage
is
hard
and
smooth
, has a
glossy
consistency, covers ends where bone meet. prevents
friction
between bones
ligaments
are very strong and slightly
elastic.
they hold two ends together ensuring
stability
whilst allowing
movement
synovial membrane
is a layer that lines the
synovial joint
and produces synovial fluid
