The Structure of the ANS System and the Effects it Has Shown to Have on Physiological and Behavioral Functions
The ANS is a purely motor system, meaning that it transmits impulses out of the CNS to various motor or effect or organs of the body. These include the smooth muscle of the blood vessels and the gastro intestinal system, heart muscle, and several glands such as the pancreas, the adrenal medulla and the salivary glands. The ANS first function is to regulate internal bodily processes. It does this by sending information to and from the CNS. Although the ANS is very important it is the CNS that is in control.
The ANS operates as an independent or autonomous control system. Although we learn as we mature in age to control our autonomic functions, such as urination and defecation, these would occur in the absence of control of them. These bodily processes and many others are controlled by the ANS without requiring conscious effort. To enable the ANS to perform its functions it has two branches. The sympathetic branch that produces a pattern of arousal in the body, with h...
...r within. The physiological indicators are primarily recognized through “vision, hearing, olfaction and even the pressure of the skin,” where they are primarily found within the hypothalamus, a key factor to the animal’s homeostasis. (3)
As previously mentioned above, psychobiology studies psychological phenomena in terms of biological processes. Studies that are deemed to be psychobiological must consist of both psychology and biology. The study focused on the ar...

The Autonomic Nervous System is responsible for the functions of the body that are not thought about to control. When this system dysfunctions, it can cause havoc on the human body. One example of this would be Dysautonomia. Dysautonomia is a rare but serious disease that affects the autonomic nervous system, has many symptoms, and offers few treatment options.

The ANS is part of the peripheral nervous system, being split into sympathetic pathways, which prepare the body for action and parasympathetic pathways which prepare the body for rest. This regulates the functions of the body and some of the muscles automatically.

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.
Firstly, there is various of sensing activities as in seeing and hearing as in a sense of understanding of what is seen and heard. Secondly the sense of feeling in numerous parts of the body from the head to the toes. The ability to recall past events, the sophisticated emotions and the thinking process. The cerebellum acts as a physiological microcomputer which intercepts various sensory and motor nerves to smooth out what would otherwise be jerky muscle motions. The medulla controls the elementary functions responsible for life, such as breathing, cardiac rate and kidney functions. The medulla contains numerous of timing mechanisms as well as other interconnections that control swallowing and salivations.
The ANS is positioned just below the medulla oblongata in the lower brainstem. The medulla is responsible for many major functions, such as respiration, cardiac regulation, vasomotor activity, and reflex actions; which include coughing, sneezing, vomiting, and swallowing. The input is received by the hypothalamus, which is located right above the
Within the human anatomy, an intricate and complex network of specialised nerve fibres and neurons works in collaboration with the central nervous system and peripheral system, designed to carry out the various actions humans perform every day. The nervous system is also known as the master control unit of the human body, as it operates other major functions such as the circulatory and respiratory systems (Jakab, 2006). It is composed of the central nervous system (CNS) and the peripheral nervous system (PNS). The neurons established within the various sections of the nervous system, is structured with three main parts: a dendrite which is a cluster of branches that operates by receiving information from the receptor and neurons and transferring nerve impulses to the cell body; furthermore, a cell body is composed of a nucleus, that works to provide energy and nutrients for the neuron; lastly is an axon, electrically conducted by the myelin sheath, the axon is a pathway nerve impulses pass through from the cell body. In addition, this is the process in which nerve impulses travel by to be able to access the rest of the system (Core Science, 2010). The correct function of the nervous system is vital to the daily survival of an individual, as it obtains a significant role in the control and co-ordination of the human body. Furthermore, if a situation occurs where the nervous system dysfunctions or develops a disease (such as multiple sclerosis), it would in that case threaten the current status of one’s health and cause havoc in the system.
The sympathethic nervouse system and the parasympathetic nervous system. The sympathethic nervous system of the body acts to control the bodly functions like heart rate, urination, digestion and sexual arousal. The parasympathetic nervous system controls the fight or flight responses during difficult or stressful times. This system triggers the body to fight off any stress or danger.

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.
The nervous system’s main function is to coordinate all of the activities in the body. The main organs are the cerebellum, which controls and coordinates movement. The cerebrum, is the center for conscious thought, learning, and memory. The last main organ is the brain stem. The brain stem keeps the automatic systems in your body working. Problems of the nervous system include, epilepsy, Alzheimer’s, and multiple sclerosis. You can care for your nervous system by wearing a seatbelt, wearing a helmet, and by not using drugs or alcohol. Something very confusing about the nervous system is that the left side of human brain controls the right side of the body and the right side of the brain controls the left side of the body!
