Joints are able to move because of tendons that connect the bones of the joint together. Nerves tell the brain that the joint wants to move and the brain signals movement.
Articulating Cartilage =) Hope this helps
The structure of the saddle joints is that it allows movement backwards and forwards and also upwards and downwards. The saddle joint is found in the hand and it also movement with all the other bones in the hand.
A ball and socket joint allows movement in all directions. This type of joint is formed when a bone with a rounded end fits into a socket-like structure of another bone, allowing for rotational as well as angular movements. Examples include the hip and shoulder joints.
The medial roataion is the movement of Glenohumeral joint .
A saddle joint provides the closest to omnidirectional movement.
A pivot joint is a type of synovial joint which only allows rotary movement around a single axis. One example is the proximal radio-ulnar joints.
flagella /\
The joints in our body contain a fluid known as the synovial fluid which facilitates smooth movement as it reduces the friction between the bones
Flagella are external structures that propel cells. The cytoskeleton (I believe actin and myosin are the components of the cytoskeleton responsible for movement, but I'm not sure) is an internal structure that facilitates movement by changing the shape of the cell.
The structure of the saddle joints is that it allows movement backwards and forwards and also upwards and downwards. The saddle joint is found in the hand and it also movement with all the other bones in the hand.
The purpose of expansion joint , is to anticipate movement of structure due to temperature, earthquake,settlement. In 75 mtrs length of slabs we can make expansion joint in L/2 or 75/ 2 or L/ 3 for every 25 mtrs , we provide bearing Pads for movement. , actually this also name as movement joint.
Nah. It is just there so u dont fall apart.

The thumb is the only structure in the body having a saddle joint.
There are six joints that have movement. The plvotal joint is what allows up and down movement.
The medial roataion is the movement of Glenohumeral joint .
A saddle joint provides the closest to omnidirectional movement.
To increase the angle of a joint is extension. To decrease the angle of a joint is flexion. (plato users the answer is A.)
