The Functions of the Limbic System - 1548 Words

The Limbic system compromises of detailed structures which control and regulate major affective activities such as fright, anxiety, and happiness. Further functions of the limbic system are motor functions, sensory systems, hormones and memory which all contribute to the control of affective states. These factors are controlled and regulated by different structures of the limbic system and work inter-relatedly. The central components of the limbic system compromise of the limbic cortex, hippocampus, amygdala, fornix and mammillary bodies. The limbic system also currently involves cortical and non-cortical brain structures such as diencephalon, brainstem and the forebrain. The diencephalon compromises of the thalamus and the hypothalamus, the forebrain includes the basal ganglia and amygdala while the function of the brainstem is to form a connection between the cerebrum and the spinal cord. (Hendelman, 2000). The origin of the limbic system stemmed from the evolutionary period. This is because, during the evolutionary period, brains have developed in a structure that enables mammals to adapt to their environment. For example the forebrain in mammals has evolves to fulfil this function of adaptability of behaviour to the external world (Maclean cited in Hendelman, 2000). Therefore, this has resulted in a different functions and roles of the limbic system in terms of adapting to environments such as fright and how to react in fearful situations. However, the functions ofShow MoreRelatedThe Complex Structures Of The Limbic System975 Words   |  4 PagesLimbic System The complex structures of the limbic system boarder the thalamus, belt around the fornix and the Corpus Callosum. The limbic system possesses an array of unique functions due to its complex and unique structures. The system contains the hypothalamus, mammillary bodies, septal area, amygdala, hippocampus, orbital and medial prefrontal cortex, nucleus accumbens, ventral striatum and cingulate gyrus (ebrain, 2016). The limbic lobe is mainly responsible for facilitating mental functionsRead MoreEssay on Self Destructive Behavior and Role of the I function1601 Words   |  7 PagesSelf Destructive Behavior and Role of the I function The I function describes all behavior associated with the notion of self. Is there really a specific I function and what is its role exactly? Because the I function is linked to the self, one would think that it would prevent harmful behaviors. However, there are cases where the I function does not intervene to terminate detrimental actions for example addiction and a mental disorder called Lesch-Nyhan syndrome. In both cases, a person isRead MoreHow the Human Brain Works The human brain is one of the most amazing organs in a body and at the600 Words   |  3 Pagesone of the most amazing organs in a body and at the same time the most mysterious. It is the control center of the body and it’s important to understand the complexity of the human brain. Although your brain functions as a whole, it consists of three main parts, The Central Core, the Limbic System, and the Cerebral Cortex. Then those parts break into even smaller parts. The brain is just like the computer, it depends on certain parts to work correctly and get every day jobs and even more complex jobsRead More Causes of Sexual Dysfunctions Essay1399 Words   |  6 PagesInnervations of the organs of sexuality are mediated primarily through the autonomic nervous system (12). The autonomic nervous system is the part of the vertebrate nervous system that regulates involuntary action, as of the intestines, heart, and glands, and that is divided into the sympathetic nervous system and th e parasympathetic nervous system (1). It is generally assumed that the parasympathetic system activates the process of erection via impulses that pass through the pelvic splanchnic nervesRead MoreThe Theory Of Attachment Theory1683 Words   |  7 Pagesstructure of the brain, how it develops and stress response system. When an infant is born the wiring of the brain is incomplete in order for it to develop, it needs interpersonal experience (source). Environmental influences and genetic influences can also explain how a brain develops (source). Different regions of the brain have different critical periods for growth and maturation and patterns of development in the environment influence, which systems are used and the brain develops accordingly (source)Read MoreOverview Of The Nervous System Essay785 Words   |  4 PagesThere are two major subdivision of the nervous system, the Central nervous system (CNS) which consist of the brain and the spinal cord and the Peripheral nervous system(PNS) consisting of the neutral tissues outside the brain and the spinal cord. The Central Nervous System integrates and coordinates all bodily functions, process all incoming messages and send commands to different body parts. Sending and receiving messages through the spinal cord and the part of the spinal column called a trunkRead MoreEssay about Drugs Affect on Brain947 Words   |  4 Pagesaffect the body. Drugs mess with the brain in ways that we couldn’t even imagine. From destroying brain cells that help with critical thinking to destroying cells that give us the ability to feel pleasure. Drugs take the place of our natural body functions of the body. They fool receptors of the body and make it to where our bodies produce less of what we need. Over a period of time this may produce very severe consequences on the body. With all the risks involved with drugs it’s a wonder why someRead MoreThe Brain And Its Effects On Human Brain1675 Words   |  7 Page s The brain has four main structures; the Cerebrum, Cerebellum, Limbic System, and the Brain Stem. The Cerebrum, also known as the Cerebral Cortex, is the largest part of the human brain. It is divided into four parts that are called â€Å"lobes†: there s the frontal lobe which is linked with reasoning, planning, parts of speech, emotions, and problem solving- the parietal lobe which is linked to movement, orientation, and recognitions- the occipital lobe which is linked to visual processing like objectRead MoreAlzheimer s And Depression Effects Essay1720 Words   |  7 PagesIntroduction Alzheimer and depression effects an individuals’ occupations, independence and self worth, this will be the aim and focus of the following discussion. This discussion will explore the functions and disability of this scenario which includes, the primary body systems involved in Alzheimer s and depression including the structure’s and function’s.

(Volkow Li, 2005) A view of drug addiction has been changed from the ‘choices’ of the addicted individuals to the dysfunction of brain. The drug addiction may be regarded as the disease of the brain reward system. This system, closely related to the system of emotional arousal, is located predominantly in the limbic structures of the brain. (Vetulani, 2001)
