well,in dis case,there wud've been no difference between the human body and trees...!!
when your muscle dont work as well and you cant move as fast
Fussed joints (Stiff joints) they dont move at all
They work the same as our joints.
Check your joints, universal, CV ect that is likely your problem. Like people, when cars joints wear out they dont work properly.
no they dont
A comination of cartillage and synovial fluid resduced the frinction at synovial joints. Cartillagenous and fibrous joints dont really move and so dont need to have friction reduced.
I dont think so because some of my family drinks and their joints are going to hell.
i dont know. someone else answer it
you have to go to a differents sight because we dont know
the cell systems
wood work
not necessary....most of the bones in our body DO have joints like the femur and tibia.....but some dont for example the bones that make up our skull...etc.
