The Nervous system vs. the Endocrine system The human body is a network of muscles, bones, organs and overall, it is constantly working in its own ways to make sure that the body is performs and functions properly. The most important systems in the body, the nervous and endocrine system, both play huge roles in regulating the biological processes inside an organism. They are the basic systems that pretty much control the body, helping it react properly to any external factor. The main difference between these two systems is that the nervous system uses impulses to control the muscles while the endocrine uses chemical stimuli to pass the signal to the target cells or organs. These two systems have their …show more content…

Nervous system is one of the major organ systems that is responsible for the coordination of biological activities inside the body through cells called neurons. It is composed of the brain and spinal cord which are surrounded by protective layers of bone and membrane tissues called meninges. There are two major divisions in the nervous system; first one is the central nervous system (CNS) and the other being the peripheral nervous system (PNS). The CNS is composed of the brain, spinal cord, and retina while the PNS includes the sensory neurons, ganglia, and connecting neurons. The nervous system applies control using nerves; almost as if sending a message by a telephone. The nervous system is fast due to its electrical nature. The nerve cells in this system are connected with each other in a complex manner where the neural pathways would be possible. Neural …show more content…

Each gland of the endocrine system is responsible for the releasing of different hormones, and those hormones trigger different activities in different places of the body. Hypothalamus, pineal body, anterior and posterior pituitary glands, adrenal gland, and thyroid gland are the main glands of the endocrine system while there are some other associated glands, as well. The endocrine system is known to be as the chemical information system. Some of the main functions of this system have to do with growth and development, metabolism, tissue function, sexual function, mood swings,

    The location of the pituitary gland is in the sella turcica of the sphenoid bone and attaches to the hypothalamus(Marieb & Hoehn 441). The Hypothalamus is included in the function of the pituitary gland as it sends chemical stimulus to it(Marieb & Hoehn 442).Part of the pituitary is called the “ master endocrine gland” due to the fact that is produces many hormones that affect the whole body(Shannon 175).This part of the pituitary gland is called the anterior pituitary(Marieb & Hoehn 601). There are six hormones that the anterior pituitary secretes normally. These Hormones are growth hormones,thyroid stimulating hormones,adrenocorticotropic hormones,luteinizing hormones,follicle stimulating hormones and prolactin hormones( Shannon 175).The Hormone prolactin is one that in normal function stimulates the act of lactation for new mothers to feed their baby(Shannon 175).

    While the respiratory and cardiovascular systems are most reliant on one another, all body systems require a functioning circulatory cycle in order to thrive. Blood circulation and consistent transfer of oxygen to cells is required to maintain cell and tissue life. Disturbances to this process will cause cells and tissues to die (Red Cross 48). This state of balance and functioning body systems is referred to as homeostasis, defined as a “condition of equilibrium in the body’s internal environment due to constant interaction of body’s many regulatory processes” (Tortura 8). Changes or disruptions to homeostasis are regulated by the Endocrine and Nervous systems of the body. The endocrine system is made up of glands placed throughout the body

  • Endocrine Disruption

    An analogy that fits very well with the study of the endocrine system is that of a message in a bottle. We can think of the body as a river, and a specific hormone may be a bottle containing a message. The organs or glands mentioned above would manufacture the “bottles'; (hormones) that would be released into the river (blood stream). If there were no receptor sites for the hormones in the body, then they would continue to flow along the river and probably not make their destination. However, there are systems of receptor sites that enable specific hormones to bind in specific places. Structure also plays a major role in determining which hormones are able to bind to which receptors.

    The human nervous system is divided into two parts, the central nervous system and the peripheral nervous system. The central nervous system, CNS, is just the brain and spinal cord. The peripheral nervous system, PNS, includes the nerves and neurons that extend outwards from the CNS, to transmit information to your limbs and organs, for example. Communication between your cells is extremely important, neurons are the messengers that relay information to and from your brain. Nerve cells generate electrical signals to transmit information.

    The thyroid gland is part of the endocrine system, and it is controlled by the pituitary which is known as the “master gland” of the endocrine system. The pituitary controls the thyroid by producing Thyroid Stimulating Hormone (TSH) which stimulates the production of thyroid hormones. . The thyroid gland secretes two main hormones: Thyroxine (T4) and Tri-Iodothyronine (T3). These hormones increase metabolic rate, heat production, oxygen consumption, appetite, growth hormone secretion, alertness and quicker reflexes. The thyroid gland is located in the anterior portion of the neck, beneath the Adam’s apple. It is divided in two lobes on either side of the windpipe: right lobe and left lobe. These lobes create what looks like a butterfly shape. The gland is essential to the contribution of maintaining the homeostasis of the body. It plays a role in monitoring the body’s expenditure of energy and running the body’s metabolism.

    Almost all animals have a nervous system. Neurons bundle together to form nerves. The purpose of the nervous system is to coordinate all activities of the body, and enables the body to respond and adapt to changes both inside and outside. The central nervous and the peripheral nervous systems are very similar but different at the same time. The CNS is made up of the brain and spinal cord and functions mainly to process information and determine the appropriate responses. The central nervous system receives sensory information, figures out a response, and initiates a motor response if appropriate. The CNS is protected by the skull, vertebral column, and a membrane. The spinal cord provides communication between the brain and the peripheral nerves

    It is the idea that the mind and body are not separate entities. Rather, they are intricately connected, interacting with each other in many ways. The body's three main regulatory systems are the central nervous system (which includes the brain), the endocrine system (which produces hormones), and the immune system. These three systems work together and affect one another. Researchers who study the mind-body connection examine these interactions, and are particularly interested in the effects of emotions and thoughts on physical health.

    Most of the body’s functions such as, thinking, emotions, memories and so forth are controlled by the brain. It serves as a central nervous system in the human body. The mind is the intellect/consciousness that originates in the human brain and manifests itself in emotions, thoughts, perceptions and so forth. This means that the brain is the key interpreter of the mind’s content.

    The nervous system is composed of all nerve tissue in the body. This organ system forms a communication and coordination network between all parts of the body. It plays a major role in everyday activities such as breathing, walking even blinking. It is made up of nerve tissues to receive and transmit stimuli to nervous centers and initiate response. Neurons are nerve cells that transmit signals from one location of the body to another. With damage to the nervous system the body would not be able to function properly. The body has to be well taken care of in order to insure proper regulation. The two anatomical divisions that work hand in hand to help regulate the nervous system are the central and peripheral nervous system. According to the Campbell’s seventh edition biology book the nervous system is the most intricately organized data processing system on earth. It is a complex collection of nerves and specialized cells.
