Functions of the skeleton
1.Support-Skeleton holds body up
2.Shape-Gives shape to body
3.Protection- Skull protects brain
Backbone protects spinalcord
Ribs protect lungs
4.Movement:Bones provide rigid levers which muscles csn pull off
5.Manufacture of BCs- RBCs WBCs and platelets are made in bone marrow
How many bones are in the skull
22
how many bones in the spine
33, called vertabrae
Region and no. of vertabrae in spine
Region—————No.of Vertabrae
Cervical(neck) | 7
Thoracic(chest) | 12
Lumbar(back) | 5
Sacrum(hip) | 5
Coccyz(tail) | 4
How many pairs of ribs do we have
12
Label parts of a TS of a typical vertebra
Neural spine (pointy out bit)
Transverse process (long side)
Neural canal (Smaller hole in mid)
Centrum (Big pocket at bottom)
Facet (circle on sides)
What is the common function of Neural Spine and the Transverse Process in a typical vertebra
For muscular attachment
Whats the function of the neural canal of a typical vertebr
Contains the spinal cord
Whats the function of the centrum in a typical vertebra
Gives strenght
Whats the function of the facet of a typical vertebra
Where next vertebra rotates against
True or false
All ribs are attached to the vertabrae of tbe spine
True
What are classified as true ribs
The top seven ribs attached to the breastbone at the front of the body
What are classified as false ribs
The next three ribs (8,9,10) attached to eachother at front of chest by cartilage
What are classified as floating ribs
The bottom two ribs as they are only attached to the spine they dont attach to anything at he front of body
What does the pectoral girdle consist of
Clavicle (collarbone)
Scapula (shoulderblade)
lWhat is the pelvic girlde composed of
To halves of the hip joined to the sacrum
What flexible fibrous protein is in Cartilage?
Collagen
Why is cartilage slower to heal than bone?
It lacks blood vessels and nerves, for transport it depends on materials diffusing through to cells that form it.
Bone has a rich blood supply
Where is cartilage found?
Pinna of the ear
The nose
The trachea
In the discs between vertabrae
Covers ends of bones
What is the function of cartilage
Protects bones by acting as a shock absorber and allows friction free movement
Whats the name of the membrane that long bones are enclosed by
Periosteum
What does the membrane periosteum contain
Periosteum encloses long bones such as the femur
It contains blood vessels and nerves
