Sixth Sense: The Vomeronasal Organ
"We are all more influenced by smell than we know." (Hercule Poirot)
....Murder in Retrospect, Agatha Christie
Biologists have long realized that the noses of most vertebrates actually contain two sensory channels. The first is the familiar olfactory system, which humans possess. The second channel is the vomeronasal complex, a system that has its own separate organs, nerves, and connecting structures in the brain. The function of the vomeronasal system is the detection of pheromones, chemical messengers that carry information between individuals of the same species. It was widely believed (as I found in some of the older texts I examined) that humans had long ago discarded this sensory system somewhere along evolution's trail. But convincing behavioral and anatomical evidence has since brought the notion of a human vomeronasal organ (VNO) into the realm of scientific fact. Some thirty years ago, when anatomist David Berliner was studying human skin composition using scraped skin cells from the insides of discarded casts, he found that when he left vials containing skin extracts open, his lab assistants would become more friendly and warm than usual (1). When, months later, he decided to cover the vials, the warm and relaxed behavior was noticeably reduced. These findings led him to investigate the possible existence of odorless human pheromones and a "sixth sense" organ to detect their presence, a VNO.
While this early evidence was not empirical, anatomists have since found that all humans display two tiny pits, with duct openings, on both sides of the septum just behind the opening of the nose (3). The duct leads into a tubular lumen lacking a thick, distinct sensory epithelium. ...

Purpose- To identify the functions of the cranial nerve of the peripheral nervous system such as the olfactory, optic, oculomotor, trochlear, trigeminal, abducens, facial, vestibulocochlear, glossopharyngeal, vagus, accessory, and the hypoglossal nerves. I will examine these functions with a series of behavior tests on my partner who is Jazmine Cooley to see if all nerves are functioning properly and if they are not, then this will be considered an identified dysfunction of a cranial nerve which is a diagnosis.
Keeping with the legacy of American history, the African American family is a topic of controversy and concern. While other aspects of the family are studied, it could be argued that the area of African American motherhood receives the most attention. Unequivocally, African American mothers are depicted as matriarchs, crack-mothers, and welfare queens. In addition, Black mothers are often portrayed as lazy, irresponsible, destructive, and even worthless. These stereotypical images of African American mothers are important because they have powerful implications for African American moms, and for their families at large.
According to Brea Darnell, cheerleading is not a sport because of “the inability to compete against an opponent. One of the most important requirements of a sport [is] to compete against another opponent, not just cheer to support your team” (Daily Republic). Pom-poms and sideline chants are aspects of sideline cheerleading that lack in contributing to the definition of competitive cheerleading. Competitive cheerleading is a different side of cheerleading that consists of tumbling, jumping, and dancing, alongside a greater amount of contact activity in comparison to sideline cheerleading. Lori A. Selke, a writer for Livestrong.com, creates the argument that, “in order to gain and maintain those athletic qualities, a competitive cheerleader must train as hard as any other athlete… In addition to attending cheer practice to practice stunting, tumbling, and dancing, cheerleaders must also weight lift and work out several times a week” (Selke). The arrogation of cheerleading illuminates why it is a sport and not just an activity because of the overall devotion to the sport and time a cheerleader must generate to practicing, refining, and executing skills, similar to any other athlete in
From an outsiders perspective one may see brainless and beautiful robots, which scream and perform neat tricks. This is not the case from the inside; cheerleading is so much more than that. Many people are under the impression that cheerleading is not a sport. I am the voice of reasoning that will let you in, and I will show you that cheerleading, in fact, is a sport. Cheerleading requires much physical demand from the body just as any other sport would. Cheerleading, in general, is a team effort. There are many sides to cheerleading, which make it a versatile sport. When it comes to cheerleading there’s more to it than what meets the eye.
Because some cheerleading squads don’t compete, society thinks of it merely as a physical activity. Even though cheerleaders’ main purpose is to support other athletic activities, cheer squads whom compete, follow all physical criteria to be considered a sport. Cheerleaders put forth an incredible amount of determination. They practice tirelessly to show off their skills, with little or no recognition for their efforts. Cheerleading is a sport because it requires physical fitness, skill, dedication, and stamina. Cheerleading should be considered a sport globally.

The New York Times states that cheerleading is the fastest growing girls’ sport, yet more than half of Americans do not believe it is a sport. A sport is defined as “an athletic activity requiring skill or physical prowess and often of a competitive nature” (dictionary.com). Cheerleading at a competitive level is physically demanding and requires team work to be the best. The misconception of cheerleaders being weak, nonathletic crowd entertainers makes people believe cheerleaders are not athletes and that cheerleading is just a hobby but cheerleaders that compete at a competitive level are in fact athletes because it meets the standards of what a sport is, which includes rules and regulations, and overcoming air resistance.
Stephen Edwin King was born on September 21, 1947 at the Maine General Hospital in Portland, Maine. His parents were Donald Edwin King and Ruth Pillsbury King. Stephen being the only natural born child in the family and his older brother David having been adopted at birth two years earlier.
Cheerleading has all the elements to be a sport, being a physical activity, competes against other team for entertainment purposes. I have given differences and similarities as I compared cheerleading to other well-known sports. Show them some respect, it’s time you become more accepting to the obvious, that cheerleading is a sport.
Cheerleading has not always been a feminine sport. In the 1880’s, Princeton University created an all-male pep club to the football game against the University of Minnesota. Since then cheerleading has evolved profoundly. In the late 80’s Cheerleading competitions began with the help of the Universal Cheer Association. Cheerleading Competitions require a vast majority of time dedicated to practices and teammates. The process of creating a routine no longer than two-minutes and thirty-seconds, with at least one cheer, and a segment of music is very time consuming and stressful on the squad. With the help of choreographers and leaders the squad is able to produce a routine that represents their school and exhibits all their hard work in a matter
I am a competitive cheerleader and as well as all the other cheerleaders in the world, I want to prove to the world that what I do best, love with all my heart, and can’t live without is most definitely a sport. Trying to clarify this long debate on how cheerleading is a sport and how it is not is my biggest intention in this paper. Polls say that 60% of the voters think cheerleading is a sport and 35% think it is not (Varnavas), so the polls are already on my side. Cheerleading should be accepted as a sport and it is all up to the voters, depending on if the voters are into competitive cheerleading or non-competitive cheerleading.
Stephen King is one of the most respected and well known men to ever write horror stories, behind Edgar Allen Poe of course. Stephen King is very famous all around the world for his novels such as It, Halloween, Carrie, The Shining, Pet Cemetery, as well as another amazing fifty-nine other novels. I have only read three of Kings books, Carrie, Pet Cemetery, and The Girl Who Loved Tom Gordon, which I have selected for my book report. Personally The Girl Who Loved Tom Gordon was my least favorite, I did not find it frightening at all, and a little boring at times. It seemed like a nine year old would not be as intelligent as the the girl in the book and very unrealistic. Not that any of his other books are realistic, just this one did not satisfy me with the amount of horror even though it is classified as a horror story.
The nose is divided into the right and left cavities and is lined with tiny hairs and mucous membrane, which secretes a sticky fluid, called mucus, which helps prevent dust and bacteria from entering the lungs. The nose moistens, warms and filters the air and is an organ, which senses smell. The naso-pharynx is the upper part of the nasal cavity behind the nose, and is lined with mucous membrane. The naso-pharynx continues to filter, warm and moisten the incoming air.
There are many issues that arise for transgender individuals, particularly those effecting one’s emotional and psychological state.
The five senses of sight, hearing, touch, taste and smell are all sensations throughout the human body. Sensation is the involvement of sensory receptors as well as the central nervous system in order to allow us to experience outside stimuli. The system that allows us to experience sensation is the sensory system.
