Summary In summary, the brain is the most important superordinate instance of our organism. It is here that a multitude of processes are regulated and executed that enable interaction with the environment. The brain also assumes control over important physical processes that influence the growth and development of the organism. Last but not least, the … Summary | Brain
Synonym lat. cerebrum, Greek. Encephalon, English: BrainThe brain is the most important organ of vertebrates and forms the superior command center of the central nervous system. It regulates all conscious and unconscious functions and processes. The brain is also the most highly developed organ of vertebrates, as its large number of networked neurons (19-23 billion … Brain
Structure The brain is divided into several brain sections: Belong to the brain stem: The end and diencephalon of the brain together form the forebrain (prosencephalon), the former consisting of the cortex, the basal ganglia and the limbic system. The latter comprises the structures thalamus, epi-, sub- and hypothalamus as well as metathalamus. The brain … Structure | Brain
The locus caeruleus is a part of the formatio reticularis in the bridge (pons) and consists of four nuclei. Its connections to the forebrain (prosencephalon), diencephalon, brainstem (truncus cerebri), cerebellum, and spinal cord are involved in specific arousal processes. Neurodegenerative diseases such as Alzheimer’s dementia, Down syndrome, and Parkinson’s syndrome can damage the locus caeruleus, … Locus Caeruleus: Structure, Function & Diseases
Introduction The hypothalamus is an important area of the brain which, as a superior control center, controls numerous vegetative bodily functions, such as food and fluid intake, circulation regulation, maintenance of body temperature and control of the salt and water balance. It also continues to determine emotional and sexual behavior. Compared to other areas of … Hypothalamus
Diseases of the hypothalamus The hypothalamus produces a variety of different hormones. Some of these hormones are called “releasing hormones”. In a hormonal control circuit, they act directly on the pituitary gland and stimulate the production of further hormones, which in turn act directly on the target organs or trigger further hormone production. In return, … Diseases of the hypothalamus | Hypothalamus
Tumors Tumors can also compress parts of the hypothalamus or the pituitary gland to such an extent that adequate hormone production is no longer guaranteed. Tumors that originate only from the hypothalamus itself are rather rare. In most cases, hypothalamus tumors are gliomas – that is, tumors that originate from certain brain tissue cells and … Tumors | Hypothalamus
Synonyms in the broadest sense Truncus encephali Introduction The brain stem, also called truncus encepahli, consists of the following components: Midbrain=Mesencephalon Afterbrain=Metencephalon from bridge (Pons) and cerebellum Lengthened medulla oblangata The brain stem of the brain comprises, from top to bottom, the midbrain, the bridge with the IV brain ventricle behind it and the adjacent … Brainstem
Cerebellum The cerebellum as a part of the brain lies on the brain stem at its back and is connected to it by three cerebellar peduncles (pedunculi = feet). From the rest of the brain (cerebrum), under which the cerebellum is located, it is separated by a cerebral plate (tentorium cerebelli, tentorium = tent). The … Cerebellum | Brainstem
The cerebral ventricles are the cavities of the brain that produce the vital cerebrospinal fluid. The brain‘s ventricular system consists of a total of four ventricles that communicate with each other and with the outer cerebrospinal fluid space in the connective tissue layer of the spinal cord. One of the most common complaints associated with … Brain Ventricles: Structure, Function & Diseases
Limbic system Anatomy & Function: The centers belonging to the limbic system are sometimes not clearly defined. They are all located near the brain bar (corpus callosum). The limbic system generally includes the following structures: The amygdala lies in the temporal lobe. It plays a decisive role in the emotionally determined regulation of vegetative parameters. … Limbic system | Forebrain
Synonym ProsencephalonThe forebrain is a part of the brain and thus belongs to the central nervous system. It includes the diencephalon (diencephalon) and the cerebrum (telencephalon). These emerge from the forebrain vesicle during the embryonic development phase of the brain. The forebrain has a multitude of functions, the cerebrum is essential for numerous processes such … Forebrain
