Compare and contrast the role of the endocrine system and the nervous system, in coordination

Extracts from this document...


Compare and contrast the role of the endocrine system and the nervous system, in coordination Both the endocrine system and the nervous system are vital to the survival of organisms. To appreciate their similarities and differences fully we must review their function within humans. The nervous system coordinates the activities of muscles, monitors the organs, constructs and processes input from the senses, and initiates actions or responses. The endocrine system is a control system of ductless endocrine glands that secrete chemical messengers called hormones that circulate within the body via the bloodstream to affect distance organs (referred to as target organs). Both systems are similar in that they affect a target organ or organs, however their affect on these organs is quite different. ...read more.


These differences may be related to the speed at which hormones and nerve impulse are transmitted. Nervous impulse travel as waves of depolarisation along long nerve fibres by a method known as salutatory conduction, where the impulses jump from one Node of Ranvier to the next, speeding up the transmission. Hormones however, travel through the blood in which case they travel slowly. An exception to this fact can be said to be given by the adrenaline hormone. Adrenaline plays a central role in the short term stress reaction, i.e. the physiological response to threatening or exciting conditions (fight or flight response). Although it is relatively slower than the transmission of nerve impulses, it is comparatively faster than other hormones and its effects are usually short lived e.g. ...read more.


This can also be applied to the endocrine and nervous system. Gonadotropin releasing hormone (GnRH) is a peptide hormone responsible for the release of FSH and LH from the anterior pituitary. GnRH is considered a neurohormone, a hormone produced in a specific neural cell and released at its neural terminal. A key area for production of GnRH in the hypothalamus is the preoptic area, that contains most of the GnRH secreting neurons. This can be said to be an example of how both systems work together. To conclude the endocrine system is in charge of body processes that happen slowly, such as cell growth. Faster processes such as breathing and body movement are monitored by the nervous system. However even though the nervous system and endocrine system are separate systems, they often work together to help the body function properly. ...read more.
