Anatomy of the Facial Nerve The facial nerve is the seventh cranial nerve; it emerges from between the medulla and the pons, and travels through a 30mm intraosseus canal in the skull until it exits via the stylomastoid foramen and the “motor root” of the facial nerve forms the parotid plexus, splitting into 5 terminal branches i.e. temporal, zygomatic, buccal, marginal mandibular and cervical branches and innervates the muscles of facial expression, stapedius muscle, stylohyoid muscle and the posterior

Abstract This investigation explores both short and long term effects of psychedelic drugs on the brain, citing research from fifteen peer-reviewed sources. Within the paper are biological explanations of how psychedelics trigger various effects by interacting with serotonin and dopamine receptors. Following this are case studies in psilocybin mushrooms, salvinorum A, and dextromethorphan. Medical studies administering these psychoactive substances to participants illustrate classic hallucinogenic

the effects it takes on the brain. Most people view the effects of video games on the brain as a bad thing, some people view the effects of video games as a good thing.

desperate attempt for one to improve specific skills. Once a specific rhythm of movement is repeated enough, the motor neurons actively engaged in these movements communicate with the basal ganglia region of the brain, which is located just above the spinal cord and next to the cerebellum. This brain region is composed of hundreds of millions of specialized glial cells known as oligodendrocytes, which play a crucial role in muscle memory and hand-eye coordination. This muscle memory process expands a significant

phenomenon are most popular (Yacoub & Ferrucci, 2011). Deafferentation occurs when the destruction or injury to sensory nerve fibers causes an elimination or interruption of action potential propagation along an afferent nerve pathway. The areas of the brain that have lost sensory stimulation due to deafferentation may experience hyperexcitability. Hyperexcitability is caused by one or a combination of increased neurotransmitters in the presynaptic region of neurons, or increased receptors on the postsynaptic

Professor Gordon Ruesch Comp 1A September 3, 2014 How the Brain is Like a Colony of Ants: Response In Edward O. Wilson’s educational article, “On Free Will-And How the Brain is Like a Colony of Ants”, Wilson compares the brain, the mind, and consciousness to a community of ants. Through this analogy, Wilson portrays the human brain as an extremely elaborate organ. In its complexity and in all of its contributing parts, the brain is indeed similar to a colony of ants. Like the many individual

The adolescent brain and the adult brain have many similarities and differences. A difference that Richard Knox explains in his article between the teen brain and the adult brain is the white matter coating your nerves. “That’s because the nerve cells that connect teenagers’ frontal lobes with the rest of their brains are sluggish. Teenagers don’t have as much of the fatty coating called myelin, or “white matter,” that adults have in this area. Think of it as insulation on an electrical wire. Nerves

Americans are addicted to sugar is because when sugar is absorbed into the human bloodstream sugar is sent to the brain , which according to Dr. Lustig, a specialist in Neuroendocrinology “stimulates the same areas as cocaine or heroin” (Rose). When sugar is digested, it makes one want to eat more and more of it, because the body naturally craves sugar. If sugar affects the same areas of the brain as cocaine or heroin, then why is sugar, so widely available in society and why is sugar so readily given to

In spite of Multiple Sclerosis (MS), profundity of the body sightsees five distributed resources that account within the study produced through both Internet and novel resources. The studies include the affiliations alongside the association of the Central Nervous System (CNS). Nonetheless, the articles incorporated, fluctuate in the usage and meaning of the CNS. Stoppler (2014) believes "humans diagnosed with Multiple Sclerosis habitually occur difficulty focusing on two tasks simultaneously
