  • Sympathetic Nervous System Case Study

    The parasympathetic division, is associated with actions that conserve and restore energy. It is central during rest, sleeping, digesting food, lowering metabolic rate and restoring blood pressure and resting heartbeat. The parasympathetic system is also referred to as the craniosacral system i.e. preganglionic…

  • Essay On Multiple Sclerosis

    damage to the body. The effects of multiple sclerosis are seen as the result of occurrences taking place at a more molecular level. “If an axon loses myelin, it still lacks sodium channel in the areas previously covered with myelin, and most action potentials die out between one node and the next” (Kalat, p.44-45). Multiple sclerosis will present itself with a wide array of…

  • Locomotor Behavior Essay

    of these neurons occur periodically, which gives rise to the spontaneous tail coiling behaviour (Saint-Amant and Drapeau, 2000). The slow depolarisation arises early on in development from between 17 and 20 hours post fertilisation to produce action potentials for the initiation of activity (Brustein et al.,…

  • Descartes Mechanism Theory

    research prompted Herman von Helmholtz; who stressed a mechanistic attitude supposing a person’s senses performed comparably to machines. He wanted to determine reaction times of neural impulses which were the mechanism that influenced reflexive actions. These three scientists’ research was predicated by the theories of…

  • Similarities And Differences Of Neururotransmitter And Hormones

    switching. Neurotransmitters are released closed to their active site and are synthesized. Hormones are found in the endocrine system. Hormones travel through the bloodstream to their targets. The response can take up to second or hours to begin. The action they produce can last a long time. A single hormone can…

  • Neuroeconomics The Neuroscience Of Decision Making

    Neuroeconomics: the neuroscience of decision making Neuroscience is a scientific field that studies brain activity though changes in brain blood flow. Neuroscience is the discipline in charge of studying through the nervous system activation that occurs in areas of the brain. The body receives information by its interaction with the world and that information gets through our senses, that information is caught from the nervous system and passes through the spinal cord until it arrives to the…

  • Scholapedia's, I Am Thalamus?

    I am Thalamus according Scholapedia, am a small part of the brain located between in the middle and the center of the brain and I’m connected to the cerebral cortex and the midbrain thru nerves. I have many functions, but my main function is to regulate the voluntary motor control, the consciousness whether a person is asleep or awake (the sleep cycle), sight, sound, taste, and touch. I’m composed of 3 different groups of cells; the sensory relay cell or nuclei which receive sensation or…

  • Voluntary Human Movement

    Neurological Factors Affecting Movement Voluntary human movement is regulated and controlled by complex interactions within our central and peripheral nervous systems. The three major types of sensory input come from the visual (eyes), vestibular (inner ear), and somatic (body) sensory systems. The somatic sensory receptors found in muscles, tendons, ligaments, joint capsules, and skin are collectively known as proprioceptors and they gather information about body position and the direction and…

  • Amyotrophic Lateral Sclerosis

    Amyotrophic Lateral Sclerosis Neurologist Jean-Martin Charcot in 1869 discovered Amyotrophic Lateral Sclerosis (The ALS Association, 2015). ALS is more commonly referred to as Lou Gehrig’s disease after Lou Gehrig, a great American baseball player whose career unfortunately ended abruptly due to this incurable degenerative disease. ALS is the deterioration of motor neurons in the brain and spinal cord that leads to muscle weakness. This significant decrease in muscle strength eventually…

  • The Human Body: The Peripheral Nervous System

    The human body is a unique formation that represents how every component, whether it’s a chemical, cell, or organ all have an important role to have a healthy physiological and anatomical system. Dividing into which part of the body they control most, they create the organ systems that are the nervous, respiratory, articulatory, digestive, endocrine, and the cardiovascular system. The neurological, or the nervous, system is our control system that regulates impulses, chemicals, and commands to…
