The Endocrine System

Explain the characteristics of the endocrine system that make its reactions different from those of the nervous system.

The endocrine system glands produce hormones in the body to allow the body to regulate many functions such as sleeping, metabolism, reproduction, growth, development and it regulates the body's behavior. The endocrine system has an impact on almost all of the organs in the human body (Zimmermann, K.A., 11 March 2016).

One gland which has an important role in the endocrine system is the pancreas which is an organ in the upper abdomen. The pancreas has two main functions the pancreas excretes enzymes to break down proteins, lipids and carbohydrates and nucleic acids in food therefore functions as an exocrine gland. The hormone insulin and glucagon are produced in this organ and serve as an endocrine gland .The function of these hormones being created are controlling blood sugar levels.

The nervous system uses sensory receptors, nerves and your brain to control your cells, and acts quickly. The endocrine system uses your circulatory system and hormones to care for your cells and acts more slowly. The reproductive system and endocrine systems use hormones to function. The nervous and endocrine systems are connected by sending information to the hypothalamus and uses the autonomic nervous system to transmit what activity needs to take place in the body. This activity might be what hormones are needed, or what sensations the body feels. While the nervous and endocrine systems send information to the hypothalamus, the reproductive system receives information from the hypothalamus. So all three systems do work together, although

*Endocrine glands produce – hormones, they work with other hormones to perform many functions including: control water & electrolyte balance, regulating carbohydrate metabolism, working as neurotransmitters, maintaining stress & inflammation, regulate reproductive functions

1. Neurons is a basic building block of the nervous system. The sensory nerves carry the message from body tissues to the brain and spinal chord to be processed. The motor neurons are then used to send instructions to the body tissue from the brain and spinal cord. Dendrites, which are connected to the body cell (soma) receive information and pass it through the axon. Myelin sheath covers the axon and helps speed the process. When triggered by a signals from our senses or other neurons, the neuron fires an impulse called the action potential. The resting potential is the neuron’s visual charge of positive

Six different hormones produced by the anterior lobe will be studied here. Three of these have direct effects on the body, the other three control other glands.

Diabetes is a chronic condition involving glucose in the blood. It is caused by a problem in the way the body makes or uses insulin. Insulin, a hormone that is necessary for glucose to move from the blood to the inside of the cells. The body cannot use the insulin for energy if it cannot get into the cells. Diabetes occurs when the body has too much blood glucose due to either the pancreas does not produce enough insulin or the body cannot effectively use the insulin produced.

The Endocrine System is made up of the pituitary gland, thyroid, parathyroid, pancreas, thymus, ovaries, testes, adrenal glands, and the hypothalamus. These glands secrete hormones that help maintain homeostasis in the body. The endocrine system releases hormones that promote growth, development, reproduction, and metabolism.

The uterus of the rat that received injections of estrogen was found to weigh more than that of the rat that received injections of saline.

The endocrine system is a group of glands distributed throughout the human body. This group of glands secretes substances called hormones. These hormones are dumping into the bloodstream (Shier, Butler & Lewis, 2009). The endocrine system does not have a single anatomic location. It is dispersed throughout the human body. The final purpose of this process is to control, regulate, and coordinate the functioning of the human body. Some body functions can be activated or inhibited by hormones, which are secreted in very small quantities. The hormone related diseases may be due to hyper secretion, or a hypo secretion. The hormones secreted by the endocrine glands regulate growth, development and function of many tissues, and coordinate the

Figure 2: The figure below illustrates how the interior structure of the pituitary gland and hypothalamus facilitate for hormone secretion. The pituitary gland consists of the posterior and anterior lobe. It is lined with

The Pituitary Gland - The pituitary gland is a pea-sized structure located at the base of the brain, just below the hypothalamus, to which it is attached via nerve fibers. It is part of the endocrine system and produces critical hormones, which are chemical substances that control various bodily

Peptides hormones are usually large and hydrophilic charged, and cannot diffuse across a plasma membrane. Therefore the receptors they bind to are on the cell surface. When the peptide hormone binds to the receptor of the cells surface of the target cell it activates the receptor and as a result transmit a signal to the cellular interior. The purpose of this signal can be to turn on a protein kinase that phosphorylates (which is a modification of proteins in which an amino acid residue is phosphorylated) specific proteins and alter their activity however it could also release a second messenger into the cell this cell can be calcium, this amplifies the signal and changes many different cellular

Do you know how you were born? Do you know how you came to be? The reproductive system is the system that made that all possible. Without the reproductive system you wouldn’t have been born. In order to produce offspring, the male and female reproductive systems have to be different. Each system has different parts, problems and care. Each system have different purposes, the male reproductive system’s function is to produce sperm, while the female reproductive system’s function is to produce ova, store ova and house a fertilized egg.
