The, The Endocrine System, And Genetics

The stimuli will cause a specific reaction within the body depending on the signals – these allow the body to perform its functions smoothly and aid in quick reflexes. Different nerves and cells implement their own distinct actions, each which serve their own purpose in the total body operation.

There are eight theoretical perspectives in contemporary psychology. Any topic in psychology has many approaches that have a variety of perspectives for each that is given. Starting with the biological perspective, it is noted that physiology has played a major role in psychology. The organ systems such as the nervous system, endocrine system, immune system, and genetics are greatly emphasized in studying physical bases of human and animal behavior. Neuroscience more specifically studies the nervous system, particularly the brain. The next theoretical perspective is the cognitive perspective, which is a relatively modern approach. It focuses on the important role of mental processes in how people process and remember information, develop language,

Everything we do is a product of neural communication, whether that be reacting to senses or feeling emotions, it is all due to us having neural communication through millions of neurons passing small electrical signals throughout the body through such pathways as the central nervous system and the peripheral nervous system and passing information to and from the brain. These ‘’neurons’’ are made up of Dendrites which are connected to a cell body, or also known as the soma, these are tree-like feathery filament ‘’message receivers’’ that collect these messages from other neurons it is connected to, neurons are connected through a dendrite to axon terminal connections and pass these ‘’messages’’ through the body as action potentials.

*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

Biological sex is determined by chromosomes in your genes. At prenatal development, only a few weeks after conception, there is no notable difference between male and female structure until the Gonadal Ridges, the structure which develops either female or male sex organs, grows to determine the sex of the baby. All prenatal babies have genitalia that appears distinctly feminine until at three months, hormones- testosterone if the baby’s to be a boy, and oestrogen if the baby’s to be a girl- is released and the baby develops into the hormone determined gender. For these reasons it is believed that there is a direct link between chromosomes and sex, and therefore sex and

Biological psychology, of biopsychology, is the application of the principles of biology to the study of mental processes in terms of bodily mechanisms. The view that psychological processes have biological (or physiological) correlates, is the basic assumption of the whole field of biological psychology. Biological psychology is a hopeful domain, one that has much to offer in terms of improving the quality of life of the healthy as well as those suffering from disorders. It also contributed important therapeutic data on a variety of conditions, including: Parkinson 's Disease, Alzheimer 's Disease, Clinical depression, Schizophrenia and a lot others. Humans have very complex nervous system, they use neurons and neurotransmitters to make the highest active communication network throughout the body. “most of the body’s neurons are found in the central nervous system(CNS), which consists of the brain and spinal cord” (psychology 5th edition). “Neuroscience emphasizes that the brain and nervous system are central to understanding behavior, thought, and emotion. (Van Horn, 2014; Zhao & others, 2014). Therefore, for biological psychologist all that is psychological is first physiological. All thoughts, feeling & behavior ultimately have a biological cause.” We are benefited from biological approach for diagnosing and treating human brains Ex. Schizophrenia. Scientists are also able to create medications for different types of illnesses. Besides having psychologists

Every behavior begins with biology. Our behaviors, as well as our thoughts and feelings, are produced by the actions of our brains, nerves, muscles, and glands. In this chapter we will begin our journey into the world of psychology by considering the biological makeup of the human being, including the most remarkable of human organs—the brain. We’ll consider the structure of the brain and also the methods that psychologists use to study the brain and to understand how it works.

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

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.

The human body composes with many systems, and each of this system plays a major role in maintaining life. The hematology and the endocrine system can be considered as the two most important system in the human been body function. Any abnormality can result in disease. For example, a low serum of thyroid hormone and iron level can make the patient to feel very tired. As part of this assignment in the two case scenarios, these disorders will be elaborate with their differential diagnosis, the critical values, and the management

The levels of hormones in the body can be regulated by several factors. The nervous system can control hormone levels through the action of the hypothalamus and its releasing and inhibiting hormones. For example, TRH produced by the hypothalamus stimulates the anterior pituitary to produce TSH. Tropic hormones provide another level of control for the release of hormones. For example, TSH is a tropic hormone that stimulates the thyroid gland to produce T3 and T4. Nutrition can also control the levels of hormones in the body.The thyroid hormones T3 and T4 require 3 or 4 iodine atoms, respectively, to be produced. The people lacking iodine in their diet will fail to produce sufficient levels of thyroid hormones to maintain

Human behavior has been a mystery to scientists and psychologists for years. What causes humans to act the way they do? Is it learned by experience, or inherited from prior generations? The human brain is a complex machine driven by numerous intangibles that influence our thinking process directly and indirectly.

The nervous, endocrine, and reproductive systems are all alike in many ways and also very dependent as well. For example the nervous system works along side the endocrine system by helping us adapt and using chemical messengers to signal cells but the response may be different. The nervous system has an immediate response for the body to react to pain, temperature, and many other things. While the endocrine system helps the body to react in a slower way and can help clam the body. While both these systems rely on the messenger cells, the reproductive system reproduces these cells both male and female. All three systems rely on another's job to come together and function productively.
