Reflex action is controlled by Reflex-Arc which is a sudden immediate reaction to a sensory stimulus. Reflex action can occur as an inborn or learnt. An inborn reflex action is not needed to be learnt because it is inherited action. For instance, when we touch to extremely a hot object accidentally we move the hand away immediately without thinking. How does it happen? Reflection action is made up of five parts.
1. Receptor - such is the pain in the skin creates a nerve impulse in a sensory neurone
2. Sensory neurone travels along the nerve impulse to the spinal cord
3. Relay neurone is ensured the message is received correct in motor neurone
4. The response travels down through motor neurone to a muscle in the upper arm
5. Effector - the muscle in the upper arm receives the response and produces the effect that pulls away the hand quickly from the hot flame

Endocrine system sends out a chemical message is called a hormone. These hormones help control the growth and the development of the body, metabolism, sexual function and reproduction. Endocrine systems diffuse hormones throughout the body and the target cell responds to hormones. In order to be recognised by the cell, the hormones need to announce its arrival by binding to its receptors when they target a cell. However, if the hormones are water soluble they are not able to enter the cells membrane instead they dock with a protein on a surface of their cells. The example of water-soluble hormones can be epinephrine. If hormones are lipid-soluble such as steroid hormone is capable to pass through the plasma membrane of the cell. The example of lipid-soluble hormones can be a female hormone estrogen and a male hormone testosterone (Lumen, 2018). https://courses.lumenlearning.com/boundless-biology/chapter/how-hormones-work/ How Hormones Work.
