INTRODUCTION The human brain has a remarkable ability to manage the body functions, and process the information that allows us to act on a changeable external environment. To achieve these functions, during evolution, it developed a large computing power, and specialized functions, such as cognition, emotion and consciousness. With approximately 86 billion neurons (Herculano-Houzel, 2009), each neuron has approximately hundreds up to thousands of synapses, it has high structural complexity, and…

3. A. Cranial nerve involvement can be broken down into two portions. The anterior 2/3 of the tongue are innervated by the Chorda Tympani branch of the Facial nerve which is carried by the lingual nerve which branches off the mandibular branch of the Trigeminal nerve. Sensory component of the anterior 2/3 is maintained by the lingual nerve. The posterior 1/3 of the tongue is innervated by the glossopharyngeal nerve which supplies both sensory and taste. B. The human tongue contains multiple…

Researching the correlation amongst brain anatomy and physiology is a primary pursuit of neuroscience. Simplistic in its composition the brain is astoundingly the most complicated machine known to man. This mass of protein and fat in addition to being responsible for maintaining homeostasis also encompasses attributes that not only make us unique, creative, empathetic, moreover human. Overview of structure & function The brain of humans is primarily composed of two general classes of…

LIMBIC SYSTEM AND TINNITUS Introduction A human body is a very delicate and complicated group of systems and organs that work together. We can say that each part of the body is controlled by and connected to several many organs. Thus, many diseases and disorders in one organ can actually indicate the error in completely different organ or system. That brings us to this, The limbic system and Tinnitus. A person who has tinnitus is a person who is continuously hear noisy and annoying voices and…

proteins can turn healthy -synuclein proteins (via a toxic template) into misfolded -synuclein leading to LP. Braak, Del Tredici [10] examined brains of PD as well as asymptomatic individuals’ during intervals post-diagnosis. They believed the olfactory bulb and dorsal motor nucleus of the vagus nerve (DMV) were initially attacked by an infectious agent or environmental pathogen that causes LP, which is then transported throughout the brain retroactively (by neural pathways) [11]. Ultimately,…

handwriting may appear smaller and this is due to difficulty with repetitive actions. Nonmotor symptoms are a way to detect the disease as early as possible. The National Parkinson Foundation notes that the enteric nervous system, the medulla and the olfactory bulb which controls the sense of smell can all be affected by Parkinson’s. The theory is because of the evidence that a loss of sense of smell, sleep disorders, and constipation may be evident long before motor symptoms appear which could…

and electromagnetism. The Smithsonian Institution's Open Portal explains all six sensed of the great white shark. Great whites have an incredible sense of smell. They can smell a single drop of blood floating in the water. "The great white’s olfactory bulb is reported to be the largest of any shark" (Web). Their sense of hearing in impeccable. Their ears are small. "Inside, there are cells that can sense even the tiniest vibration in the surrounding water. Sharks also have an ‘ear…

improving the overall well – being. Aromatherapy massage brings a deeper level of relaxation, balance and health to client’s life. It stimulates the emotional part of our brain as the aroma from essential oils is sent to the limbic system though the olfactory bulb. The aroma aids the brain to release neuro messengers such as serotonin to counteract anxiety and stress and endorphins to reduce pain. It is a powerful therapy to balance the body. Aromatherapy is the use of plant substances that…

Hallucinogens are a chemical substance that causes hallucinations. Hallucinations, derived from Latin, álucinari, means to ‘wander in the mind.’ Hallucinations includes all sensory perceptions whether real or not. Psychedelics, Greek derived, translates to ‘soul and mind manifesting’ and are a class of hallucinogens that are useful tools in gaining understanding of how the brain, mind and body works. The study is complex and requires a broad and deep knowledge of the various mechanisms and…
