Student no:16472374 The nervous system and neuron communication The nervous system is a highly complex and broad area of biopsychology. People depend on the nervous system for their survival and safety.This essay will explore the components from which the nervous system is composed and their main functions. This essay will also decipher the mechanisms through which neurons communicate. According to Carlson (2014) the Nervous system is branched into two categories - the central nervous system…

The process can take place in three parts. • Filtration – This process happens in the entire nephron system. When blood goes through and into the capillary at the beginning of the nephron, small molecules, such as glucose, urea, ions and water are cleaned out and passed through the nephron tubule. The larger molecules such as blood proteins, cannot fit through the capillary wall as they are too big, therefore they stay in the bloodstream. • Reabsorption – When the small molecules are cleaned…

All the mapping areas surrounding Dillon has the youngest unit of the Quaternary period, which is the alluvial sediment. Alluvium sediment is an unconsolidated deposit of clay, silt, sand and gravel as a result of stream flows in a river valley or delta. The unlithified deposits fill a basin and lump together to form ‘alluvial’ sediments. Other Quaternary depositions include talus and landslide. Talus occupies both Block Mountain and Timber Hill, while landslide only occupies Block Mountain.…

It is then actively transported through the blood brain barrier (BBB) into the central nervous system. From here DMT enters synaptic vesicles through serotonin transporters (SERT), via vesicular monoamine transporter 2 (VMAT2), for up to seven days. Sigma-1 receptors are located in-side the presynaptic endoplasmic reticulum (ER) which regulates calcium ion flow lead-ing to change of gradients…

Hazardous Chemical: Methyl Isocyanate (MIC) In December of 1984 in Bhopal India there was an extremely large chemical leak (Schlager, 2008). The chemical was called methyl isocyanate (MIC) and was used as an intermediate to create a pesticide, or a substance that is used for killing organisms called Seven. Seven, which kills several different types of bugs and is used specifically in Asia but globally as well, is also an insecticide, or a beneficial chemical that kills insects (Living With…

Introduction When analyzing biological processes and development, Drosophila melanogaster is an ideal organism to utilize. Compared to other organisms, the functions of D. melanogaster are easier to manipulate due to its quick sedation time from carbon dioxide. These flies can be sedated in less than ten seconds with a carbon dioxide flow rate of 5L/min. D. melanogaster also produces offspring in a short amount of time (roughly 10 days at 25 degrees Celsius), which makes it a desirable species…

Introduction: Herpes Labialis, also known as the cold sore, is characterized by painful clusters of clear blisters on or around the mouth, and is often accompanied with fever. The disease is usually caused by the virus HSV-1, or herpes simplex type 1, but can also be caused by HSV-2. In a previous study, it was found that 67.6% of Americans possessed antibodies for HSV-1, establishing HSV-1 as an exceptionally prevalent virus even in developed countries 9. The virus is spread through skin to…

Name: Alexis Vick Drawer/Group #: 12 PS ID #: 1059363 Three digit mutant code: 458 BIOL 3311 Fall 2014 Lab Section: 20091/Tu4 Date: 09/29/14 TA Instructor Name: Laura Montier Drosophila Melanogaster: Decapentaplegic gene The fruit fly, Drosophila Melanogaster, has been used for years as a model for genetics. The flies are small and easy to maintain in a lab, cost-efficient, and have a quick life cycle, all qualities that make this a prime organism to utilize for genetic…

Spermatozoa are differentiated motile cells that have two main structures: the head, which houses packed DNA, and the flagellum, the motility portion that transports the sperm genetic information to the egg (1). Within the spermatozoa head both a vesicle which covers the head, known as the acrosome, and the nucleus reside; whereas the flagellum (tail) is divided by the principal and end piece (4). It is in this principal flagellum piece that we can localize the CatSper channels (2,4,5).…

THEY ARE AS FOLLOW 1. Attachment of the virus to the cell surface: This can be blocked by Enfuvirtide e.g in HIV 2. Uptake into intracellular vesicles (endosomes). Blocked by Enfuvirtide e.g in HIV 3. Uncoating of virus:- Can be blocked by Amantadine e.g in Influenza A 4. Integration of the viral DNA into chromosomal DNA of the host cell: Can be blocked by Fomivisen e.g in Cytomegaloviruv. 5.Template…
