Like tubulin, FtsZ forms filaments in the presence of guanosine triphosphate (GTP), but these filaments do not group into tubules. During cell division, FtsZ is the first protein to move to the division site, and is essential for recruiting other proteins that synthesize the new cell wall between the dividing cells.

In all cells of all domains of life (archaea, bacteria, eukaryotes) a cytoskeleton is found (notably in all eukaryotic cells, which include human, animal, fungal and plant cells). The cytoskeletal systems of different organisms are composed of similar proteins.

The Skeleton Inside You Look inside our bodies and the world of x-rays! Our bones hold us up. If we didn’t have them, we couldn’t stand, sit or walk! They provide structure for us and also protect our delicate inner organs.

The skeleton and muscles function together as the musculoskeletal system. This system (often treated as two separate systems, the muscular, and skeletal) plays an important homeostatic role: allowing the animal to move to more favorable external conditions.

The cytoskeleton provides the cell with structure and shape, and by excluding macromolecules from some of the cytosol, it adds to the level of macromolecular crowding in this compartment. Cytoskeletal elements interact extensively and intimately with cellular membranes.

FOR DEPOSIT Bone Bank Deposits Calcium is essential for the growth of strong bones and teeth. It is the most common mineral in the body. Around 99 per cent of the calcium in the body is found in the bones or skeleton; the rest is in teeth, soft tissues and blood. The skeleton is a living tissue and acts as a calcium reservoir, which needs to be topped up daily.

A large-scale example of an action performed by the cytoskeleton is muscle contraction. During contraction of a muscle, within each muscle cell, myosin molecular motors collectively exert forces on parallel actin filaments.

Bones are hard on the outside, but spongy on the inside. Bones are the framework for your growing body. Bones are living tissue that changes constantly, with bits of old bone being removed and replaced by new bone. You can think of bone as a bank account, where you make deposits and withdrawals of bone tissue. During childhood and adolescence, much more bone is deposited than withdrawn as the skeleton grows in both size and density. A healthy diet as a child builds stronger bones as we get older.

Actin filaments are shown in red, microtubules are in the intracellular matrix that supports cell shape and function. In eukaryotes, the cytoskeletal matrix is a dynamic structure composed of three main proteins, which are capable of rapid assembly or disassembly dependent on the cell's requirements.

The arms and legs are part of the appendicular skeleton. The upper bones of the limbs are single: humerus (arm) and femur (leg). Below a joint (elbow or knee), both limbs have a pair of bones (radius and ulna in the arms; tibia and fibula in legs) that connect to another joint (wrist or ankle).
