Rachel 's hand immediately moved away from the hot burner due to an automatic reflex and this prevented her from burning herself. The skin receptors in her hand was stimulated and then nerve impulse were sent to the central nervous system through the sensory neurons this is where the brain coordinates the response but not always this is known as the reflex action and in Rachel 's case her hand instantly moved from the hot burner without to much thinking.(Bbc.co.uk, 2017) In this type of automatic reflex actions are overseen by combination of neurons called the reflex arcs. In the spinal cord, the nerve impulses move from the sensory neurons to the interneurons and signals are then sent to the motor neurons which project out the spinal cord to stimulate the effector to contract like instantly moving your hand away from the hot burner this is known as the reflex arc (Owlcation, 2015).The reflex in which the hand immediately moves away from the stove is known as the polysynaptic reflex, this is a spinal reflex which is intended to protect the body from damaging the stimuli leading to stimulation of sensory and motor neurons. {(Boundless, 2017). …show more content…
Leading the afferent neurons to enter the dorsal nerve root of the spinal cord, the stimulus is passed onto the efferent neuron to reach the efferent pathway to reach the effector organ in Rachel’s case it’s the muscles in the arm leading to hand instantly being pulled back. The brain is not involved in the reflex actions as it will take more time for the impulses to travel to and from the brain. The afferent neurons taking the causal stimulus to the CNS,the spinal cord, the efferent neurons, the exciter neurons and the action performed in response to the stimulus altogether create the reflex arc.(YouTube,
Throughout Zac Unger’s memoir Working Fire the Making of a Fireman he struggles to find a place within the fire station and among coworkers. Unlike many of the fellow recruits who spent years preparing to become a firefighter, Unger an Ivy League grad simply responded to a bus stop ad. After realizing that most recruits were either former military, tradesmen or other firefighter’s kids Unger “Mostly I just stayed quite, tried to down play my existence. I figured if I could just make it through the academy without being called out as a fraud, I’d end up a firefighter like the rest of them”(Unger, 22-23). This distinction between Unger and the rest of the recruits was seen as something to be ashamed of, something to hide away.
During Netflix’s hit show Orange is the New Black Season 5 episode 6 entitled "Flaming Hot Cheetos, Literally", the female inmates receive a box of Flaming Hot Cheetos from the governor who wants them to release the hostages that they have held from previous episodes. They refuse to do so until their demands are met; once they weren’t met, they subsequently create a bonfire of the Cheetos in the front of the prison while being filmed by the press (Morelli, & McCarthy, 2017). The product placement in this episode was very obvious as the entire show focused on the ladies receiving the Cheetos as an incentive to release the prisoners as mentioned above. I didn’t feel deceived by the actors or producers, nor did I find myself any more likely to purchase Flaming Hot Cheetos than I would have before, as it’s not something that I normally eat. Also, the context in
Over hundreds of thousands of books were burned by the Nazis. The books were burned because they were filled with knowledge and ideas that would spread to people causing the Nazis to lose their perfect society. In the novel, the government burned books because reading creates independent thinking and they wanted the citizens to be ignored, so they could control them without fear of a rebellion. In Fahrenheit 451 by Ray Bradbury symbolism is used to evoke strong meaning throughout the novel. Objects such as the phoenix, salamander, and fire are powerful symbols that occur throughout the novel.

Most young adults in the United States cannot wait to turn 21, so they can drink alcohol, but not this girl. I was from a smaller community and rarely ventured farther than the rusted barb wire fences of my families ranch. However, shortly after my 21st birthday life began to change. Applications got submitted, then came interviews, tests and more interviews. “You’re hired” said a voice on the other end of the phone.
The Fire Stick, utilised by Indigenous Australians has been an essential tool in the practice of traditional land management across Australia since their arrival 50,000+ thousand years ago. Fire Stick Farming (as it is now known) shaped the Australian landscape in ways that benefited both land and Aboriginal people. A practice that increases biodiversity of plant species, offered an abundance of food, both for Aboriginal people and wildlife such as the Kangaroo and Emu, and, in turn, increased populations of these species, which were also a desired food source. Additionally, the practice of burning both small and large areas of land ensured the prevention of larger uncontrollable fires which can devastate landscapes, as evidenced by the common
Reflexes Uncovered A reflex arc consists of five essential components – a receptor, sensory neuron, integration center, motor neuron, and an effector. A reflex arc is an automatic response that protects a person from injury by allowing for immediate withdrawal from harmful stimuli. This response is present in situations that call for immediate action, such as when a person steps on a sharp object; instead of sending sensory information to the brain to be processed, a reflex arc rapidly processes and produces the protective response without having to wait for directions from the brain. The process begins when a receptor, which can be specialized cells or the dendrites of a sensory neuron, is activated by the arrival of a stimulus, and ends with the response by an effector.
In Golding’s Lord of the Flies, multiple elements, such as fire, water, earth, and air, affect the boys. Multiple British boys, spanning the ages of six to twelve, survive a plane crash and are stranded on an island with no adults. During their time on the island, each element impacts the boys on a different level, and fire has the greatest impact. Although the elements water, air, and earth have effects on the boys’ lives, Golding uses imagery to suggest that fire has the largest impact on the boys’ lives, due to the fact that it is both the most essential item for survival and that it affects all the positive and negative things that happens on the island.
THE TRIANGLE FIRE: THE DEADLIEST INDUSTRIAL DISASTER IN THE HISTORY OF THE CITY Triangle Shirtwaist Company In a tragic event accruing in the early 1900s, resulting in the deaths of 145 factory workers, ultimately led to the development of several laws and regulations that would better shape labor condition throughout the United States. In the paperback “The Triangle Fire” written by Jo Ann E. Argersinger, there are numerous primary sources with personal stories reflecting how this heartrending event shaped survivors of the Triangle Fire. Life in the Shop, All for One, and The Roosevelt I Knew are three primary sources within the text that reveal the labor conditions before and after the fire, perspectives of workers themselves, factory

A toaster oven is one of the most versatile kitchen appliances available today. They are considered to be great dual-purpose kitchen appliances because they function both as a toaster and as an oven. They can prepare anything from a simple piece of toast to a full-on meal. This versatility makes them a very popular addition to many household kitchens.
