Coordination is the working together of the various organs of an organism in a systematic manner so as to produce a proper response to the stimuli. Those organs which are specifically build to receive particular type of stimuli are called sensory organs or receptors. If temperature is too high, the enzymes could become denatured. The control and coordination of all the organs of an organism are done by the central nervous system of the body. Let's explore the central and the peripheral nervous system. Receptors are the sensory organs which receive stimuli. All these attributes of physiology can be achieved when the body works as one unit, in which its different organs and systems cooperate and work in harmony with each other, i.e. At the front of the brain are the frontal lobes which regulate fine motor control including movements involved in speech. As already mentioned nervous coordination is brought about through the various elements of the nervous system which are: Central neurons system (brain and spinal cord), made of associative neurons (inter-neurons). The information, acquired at the end of the dendritic tip (shown in the image given below) of a nerve cell, sets off a chemical reaction that creates an electrical impulse.

The working together of various organs of the body of an organism in a controlled manner to produce an appropriate reaction to a stimulus is called coordination. The CNS is the brain and the spinal cord, whereas the peripheral nervous system is the nerves and neurons which connect the CNS to the rest of the body. Our body is made up of billions of cells that get organized into different tissues. The vertebrate brain is divided into three basic regions, the hindbrain, the midbrain and the forebrain (fig 15.2). The animal body has two levels of coordination: nervous coordination (see Chapter 29) and chemical coordination. 1. Followers. Lack of glucose causes respiration to stop, whilst too much glucose may draw water out of the cell via osmosis. All these attributes of physiology can be achieved when the body works as one unit, in which its different organs and systems cooperate and work in harmony with each other, i.e. its diverse functions are coordinated. Paralysis and neurosis are the disorder of nervous system. This cell is highly adapted for communication because of its wire like projection; the dendrites which are often further branched and carry impulses towards the central cell body. The vertebrate brain is chiefly concerned with involuntary, mechanical process. The cell body is a thicker region of the neuron containing the nucleus and most of the cytoplasm. Memory track are also supposed to be present in the cerebrum. These glands are situated throughout the animal body and include such organs as the pancreas, thyroid gland, and adrenal gland.
