WHAT IS COORDINATION SYSTEM??

The definition of coordination system is work together to process information received from stimuli and to produce appropriate responses. We have two coordination systems one is the nervous system and other one is endocrine system. The nervous system are regulates the body’s activities and responses. It works by means of specialized cells called neurons which transmit information in the form of nerve impulses. Besides that, the endocrine system regulates and coordinates the body functions by means of chemical substances called hormones. The endocrine system regulates functions which require maintained responses. These include changes during the metamorphosis of some animals, growth, and the production of milk in mammals. Now, we talk about the responsive organs for coordination. There are two types of responses to stimuli, one is motor responses, the response is movement and endocrine responses, the response is the release of hormones. The responsive organs, or effectors, control motor and endocrine responses. The motor and endocrine systems need to receive an instruction from the nervous system in order to respond. Futhermore, motor responses are controlled by organs in the motor system, which consist of skeletal system , bones support the body and act as levers during movement. The skeleton is internal. And muscular system are muscles are contractile organs attached to the bones by tendons. The endocrine responses is a release of hormones. Endocrine responses are controlled by gland in the endocrine system. These glands produce hormones which are releases onto the blood and control and coordinate activities throughout the body. Both vertebrates and invertebrates have endocrine systems. The conclusion is movement scientists refer to body coordination as motor coordination, a term that describes the interactions between your muscular, skeletal and nervous systems. Clear communication between these systems creates coordinated movements. Injury, disease, alcohol, drugs and faulty postural alignment might cause communication roadblocks, which interfere with your body’s ability to coordination your movements.

nervous system is made of special cells called neurons. The neurons carry messages in the form of electrical impulses or nerve impulses. A neuron has three components:

• Cell body or cyton
• Dendrites
• Axon

1.  The cell body contains a nucleus and cytoplasm. In the Cytoplasm are embedded different cell organelles like mitochondria, Golgi apparatus, endoplasmic reticulum.
2.  From the cell body extend out two kinds of protoplasmic extensions the cell body - dendrites and axons
3. Dendrites - are short and branched processes. They carry the impulse towards the cell body

AXON

• It is a long process, may be several centimeters long. it conducts nerve impulses away from the cell body. 
• The axon has an insulating and protective sheath of myelin around it.

NEURONS has three types:

1. Sensory neurons : They carry nerve impulses from receptors to the central nervous system. They carry stimulus from receptors.
2. Receptors - > CNS. Motor neurons : They take nerve impulses from CNS to effector organs that may be a muscle or gland
3. CNS-> Effector. Interneuron or relay neurons. They are found only in CNS and make links between sensory and motor neurons

SYNAPSE

• There is no physical connection between the neurons at synapse and so the impulse has to pass through the synapse to be passed on to other neurons.
