Axon

The neuron is also a nerve cell that can transmit nerve signals to and from the brain at up to 268 mph. The neuron releases neurotransmitters (also known as chemical messengers or information) from one end of a neuron call an axon to the beginning of another called a dendrite. These electrical charges are passed or stopped through the transport of the signals. The information of the signals gets processed within milliseconds of your entire brain and this is what happens every…

brains are relaxing as well. There is no scientific theory behind how much we use of our brain. Most of us use our brains daily, to think, to react, to sense feelings, etc. You may be surprised on how much we use our brains each day. Its always active, axons are always transmitting signals toward the target of communication. Our brain contains different parts like the central nervous system, peripheral nervous system, somatic nervous system, autonomic nervous system, sympathetic nervous system,…

Health Care: Right or Privilege? We sat drinking coffee on my front porch as I listened to Linda tearfully explain that she and her husband, John, were forced to separate and divorce. Sounds odd, but it was their only solution to be able to get treatment for her recent breast cancer diagnosis. Yes, she had catastrophic insurance coverage, but with the high deductibles and limits of coverage, the exuberant cost of cancer treatment would bring them to financial ruin, and they would lose…

Anti-Calbindin binds to Calbindin (CB) and labels GABAergic neurons In our immunohistochemistry (IHC) experiment, we used anti-Calbindin as our primary antibody, Goat anti-Rabbit 488 IgG as our secondary antibody (“488” meaning that the fluorescent dye is excited at a wavelength of 488nm, fluorescing green), and DAPI-mounting serum as a DNA (nucleus) marker with blue fluorescence for reference against anti-Calbindin-marked GABAergic neurons (Lammel, 2016). While GABAergic-neuron-expressing…

Were the human body compared to a machine by today’s standards, it would be considered something of a marvel that is far ahead of its time. In addition to bringing together multiple systems to work as one cohesive unit, it also has the ability to independently maintain relative amounts of consistency and constancy within and between these systems. Comparatively speaking, if a computer is infected by a virus the user typically has to manually diagnose and remove the virus, but if a person is…

Figure 1 Myosin and actin work together to generate motion within skeletal muscles, however, a vital means of communication, uniting motor neurons and muscles, must be present prior to movement. Tropomyosin and troponin maintain control over the contractions produced by myosin and actin and provide an essential outlet for dictating instructions. Tropomyosin, a two-stranded, alpha-helical coil protein, is positioned laterally along actin filaments and is responsible for “blocking” myosin heads…

Introduction During the early stages of foetal development, differentiation of sexual organs begins. When a male foetus is developing, a cascading of genes, beginning with the sex determining gene (the SRY) on the Y-chromosome, causes the foetal gonads to develop; whereas female development depends on an absence of androgens (Bao & Swaab, 2011). Once the process of differentiation of sexual organs is complete, sexual differentiation of the developing brain commences by the permanent organising…

Falling at number eight on the thirteen steps of complexity are organ systems. These organ systems are extremely important in the makeup of organisms. Two very important organ systems are the muscular and nervous systems. Both have separate functions and organs and also have their own fair share of problems. The muscular system composes of the tissues and organs that are used to exert a force, whether under voluntary or involuntary control. Muscles are composed of long, slender cells called…

Ronald Reagan was diagnosed with Alzheimer 's disease in 1994, which was after his presidential term. Alzheimer 's disease (AD) is an incurable and debilitating chronic progressive neurodegenerative disorder which is the leading cause of dementia worldwide (Kazim and Iqbal, 2016). Many of Reagan’s speech characteristics changed and can be associated with the neurological structures such as the myelination of the neurons as well as specific genes and the thickness of the surrounding cells of the…

Schizophrenia Overview of Schizophrenia Schizophrenia is one of the challenging mental disorders that affect the way individuals think clearly, distinguish between real and unreal, manage emotions, relate to people, and function normally. Although this does not mean that a patient suffering from Schizophrenia may not live usual life. Many of Schizophrenia patients find themselves in lifelong problems due to ignorance (Kisch, 2008). Scientific studies show that although most cases of…
