Transcript bone musc 15

Bones and Muscles – they work
Together to provide structure,
Support and a means of
Locomotion .Also produce blood
Cells.
Locomotion =movement.
Skeletal and muscular
Systems work together
To allow us to move.
Function – to provide
Protection, support and the
Means for locomotion.
Bones – provide anchor sites
For muscles, protection and
Support, also bone marrow
Produces blood cells _
216 bones in our body
We have an endoskeleton =
Inside the body.
Joints – bone to bone
Connections – ex. Knee joint
Ligaments – thin, fiberous strip
That connect bones. EX = the
ACL of
the knee
ACL
Acl is
often
torn
Cartilage – cushions at bone
To bone connections (joints)
Cartilage
Cartilage is often damaged,
Torn at joints like the knee,
It plays a very important role
in providing protection and
Cushioning where bone meets
Bone (joint).
Tendons – connect muscle to
Bones.
Feel the back of your knee or
The back of your ankle for

Muscle types
Skeletal muscle – also known a
Striated or voluntary muscle,
They operate in pairs, one
Contracts and the other
Extends – ex.=bicep & tricep
Smooth or visceral muscle –
Involuntary – lines the
Digestive tract. (peristalsis )
Cardiac muscle – found only in
The heart
Muscle type
Pictures, ooo000
Tendonitis – severly strained,
Damaged, stressed tendon,
Difficulty moving, very painFull.
Arthritis – inflamed joints,
Very painful, doesn’t just
Happen to old people – old
Injuries can cause it.
