Chapter One : The myths that we “debunked” during lecture are really important. In the beginning we learned how to understand these cases and how to look for other sources to prove them wrong. When we finished reviewing these myths, it left me mindblown! I learned lots of information on how opposites attract, the lie detector test, and different learning styles. The scientific method is something that we should have learned about in elementary school but we reviewed it again because these are…

2017). In spite of this, “Brandon Steburg Sr. is the father of Brandon Jr., who was injured on a tackle for Papillion-La Vista High School in Nebraska in September. Brandon Jr. was placed in a medically induced coma to reduce pressure on his brain” (Axon, Barnett, Brady & Smith, 2016). Although some may say that it is very important to play a sport while growing up, at some point you have to ask yourself if it’s worth it for the risk of such a dangerous injury. Of course sports can be a great…

Alternative Imaging for MRI in MS MRI is a great tool for medical imaging and widely used for Multiple Sclerosis (MS), but it has some limitations in lacking specificity1. New emerging techniques such as transcranial magnetic stimulation (TMS) and optical coherence tomography (OCT) have the potential to address issues not resolved by current MRI techniques. TMS is a non-invasive technique used for monitoring the central nervous system (CNS) activity and response in a pain-tolerated manner. It…

not expect anterograte transport to interfere with the ability to identify retrogradively labeled neurons because the signal produced by anterograde labeling is weak and requires IHC amplification121,122. CTB uptake by fibers of passage or damaged axons has been reported to be minimal11,120 thus, non-specific labeling is not…

Cell-Cell Communication in Taste Buds: Activation of Type II cells by taste stimuli causes the release of ATP through pannexin hemichannels and/or CALMH1 channels. The released ATP or sour stimuli can activate Type III cells and causes release of different hormones such as 5-HT and NE via Ca2+-dependent exocytosis. In some instances NE is co-released with 5-HT (Dvoryanchikov et al., 2007; Huang et al., 2008a). The ATP released by Type II taste cells acts as a paracrine as well as an autocrine…

measuring what has happened to the matter of the brain. When researcher measure the amount of damage do the different regions of the brain 43 percent had levels that were below the average norms. There is a lot of nerve damage specifically to the axons, and cause the brain not to relays messages to different parts of the brain to executive functioning can…

hundreds of billions of neurons in the human brain, while there are millions of nerve cells throughout the entire human body. The neurons control all of your five senses: touch, smell, taste, sight and hearing. There are thin fibers in the brain, or axons, which receive signals sent from neurons (Zimmerman, 2016). If there happen to be any faults in the nervous system, neurological diseases such as…

1. What is the difference between mitosis and meiosis? Define each term, and then explain how each process contributes differently to the conception and growth of a zygote. The two ways cell division can occur are through mitosis and meiosis. In mitosis, a cell produces two clones of itself, each with the same number of chromosomes. In meiosis, a cell will produce four cells called gametes through the process of spermatogenesis and oogenesis. Gametes are most commonly known as sperm cells in…

the host immune response, infection is present and often causes recurrent illness. Seldom reinfection can occur in spite of immunity. HSV-2 invades predisposed mucosal membranes or abraded skin. Next, the virus is transported along peripheral nerve axons to the nerve cell bodies’ sacral ganglia. The virus then remains latent in the paraspinous ganglia. Factors such as fever, stress, or pain will result in reactivation which persuades viral replication. The reactivated virus travels to mucosal…

innervation of these cells could be investigated by an indirect method. The experiment would test if these cells attract neurones by chemotaxis by releasing factors to their environment. Many factors are known to be important in the growth and guidance of axons to their targets, examples include semaphorins, ephrins and neurotrophins. By screeing for these factors the mode of innervation can be…
