Movement
Movement is an essential part of any organism whether it is an animal or a plant. Movement is vital for a red fox because it enables it to hunt prey and find food, escape from predators and travel where ever it may want to go depending on the seasons. The act of moving is created by bones, muscles, ligaments, tendons and the nervous system all working in conjunction with each other to move joints. All of these parts are made up of specialised cells which have evolved to do one job in harmony with the others.
-Specialised cells
There are many specialised cells involved in the movement of the red fox.
-Bones
The are many types of specialised cells in the bones of the red fox but they are built for repairing and keeping it strong and sturdy. The cells are also built to produce red blood cells in the marrow( inside) of the bone. To keep the bones strong, the cells that form them are a cube shape and are stacked on top of each other with the nucleus in the centre. To help not wear away the bones when used in the joints, cartlidge is put in between them and a mixture made up of old flat bone cells called periosteum, coats the outside where the bone doesn't touch other bones. There are three types of bone, long, irregular and fused. Long bones are categorised not by the the distance they are but the ration of length being much longer than the width and having growth plates at each end. Irregular bones are bones that don't fall under any other category because of the odd shape. Fused refers to the bones that have been fused together in the body. The skeleton serves three purposes, protection, support/ structure and movement which are all vital parts of a foxes life.

-Muscles
There are three types of muscles in the red fox, smooth, skeletal and cardiac. The muscles all have different specialised cells for the different jobs they are required to do. The cardiac cells are very dense and have many nucleuses because that are an used in all involuntary muscles which means that they are constantly working until the organism dies or cannot be stopped when are reaction occurs.The smooth muscle cells are made up of very long and thin striations with nucleus inside these striations. these muscles are used for organs that require a muscle for example the esophagus or stomach. The last muscle type is skeletal which is the muscles that follow the bones and joints around the body allow for most seen movement for example running. These cells are long, thick striations made up of other striations inside. There is a large nucleus for a large amount of stored energy. The muscle cells are thich because of the explosive effort they provide.

-Nerves
Nerves are the cells that send messages around the body to contract and relax muscles as well as to feel pain. The nerve cell is a star like shaped cell with each of the end tips connecting to send messages throughout the body. The tips are called dendrites. There are three type of nerve cells, sensory, motor and relay. Sensory neurons send the message from the sense organs to central nervous system or the relay neuron depending on what type of action is required. The relay neuron either sends the message to the muscle or to the motor neuron. The motor neuron is the same as the other neurons as sending the message to one of two things depending on the type of reaction. It can either send it to the muscle or relay neuron.

Joints
|
The joints in an animal work by using skeleton of bones to support it's weight and the nerves send a message from the brain to the antagonistic muscles working together to contract and release at opposite times. As the muscles contract they pull on tendons that are attached to other muscles to move the joint. Surrounding the joint the are also ligaments which are pieces of tissue which keep the joint protected and straight. There are three types of joints, immovable, slightly movable and freely movable. An example of immovable joints is the pieces that fit together to build the cranium. Slightly movable can be seen in the red fox when looking at the spine because there is not a giant amount of movement but the spine also allows to bend forwards, backwards and sidewards. An example of the freely movable joint a knee joint which is used very frequently bending backwards and forwards.
