what is the axial skeleton
long axis
what is the long axis made up of
skull
vertebral column
rib cage
what is the appendicular skeleton
limbs and girdle
what is the girdles
bones that connect limbs to axial skeleton
what are the 5 main functions of the skeleton
protection
shape
blood production
calcium storage
movement

12
how many lumbar bones are there
5
how many sacral bones are there

what is lordosis
cervical and lumbar back curves
what is kyphosis
2 backward curves in thoracic and sacral regions
when do primary curves occur
foetal development
when do secondary curves occur
infancy
what is scoliosis
lateral deformation of the spine
who are more likely to get scoliosis
pubertal girls
what are 4 symptoms of scoliosis
uneven shoulders
uneven waist
1 hip higher than another
1 side of rib cage jutting forwards
what is a treatment of scoliosis
physiotherapy or bracing
what happen to thoracic vertebrae from superior to inferior direction
increase in size
what is the largest vertebrae in humans
lumbar
what is the function of lumbar vertebrae
support weight of upper body
what is the coccyx made of
5 fused sacral and 1 coccygeal
what is spina bifida
when the lower part of vertebrae doesn’t fuse
what is the issue with spina bifida
causes a gap in vertebrae column
what is the role of intervertebral discs
attach adjacent vertebral bodies and act as shock absorbers
what the 2 things intervertebral discs are made of
annulus fibrous
nucleus pulposus
