Neurons transmit information to each other and to muscles, organs and glands. The nerve impulse is sent from the axon of one neuron to the dendrite of another neuron. The neuromuscular junction as labeled in Part A of this assignment, shows that there is a space between the axon of a neuron and the motor plate of the muscle cell. The two parts do not actually touch each other. When the football player’s brain sends a message to move during the game, the nerve impulse is sent from neuron to muscle cell. The space (synapse) between the axon of a motor neuron and a muscle cell is called a neuromuscular junction. The axon of the motor neuron contains synaptic vesicles which contains thousands of molecules of the neurotransmitter acetylcholine. This acetylcholine is released into the space between the axon and the muscle cell. The muscle cell membrane has receptors to accept or to bond with the acetylcholine. This region is called the motor end plate. When the acetylcholine bonds with the protein receptors in the motor end plate, sodium and potassium gates in the region open at the same time
(AGG) Hands have always been used to create things. They separate humans from most beasts. In Ray Bradbury’s world, they separate the robots from the few humans that truly live like humans. (BS-1) Hands are used to show the lack of creativity in most citizens. (BS-2) Montag, a main character discovering his creativity, also battles with his hands. (BS-3) When the readers are introduced to the main teachers in the book, we see their hands constantly moving. (TS) Ray Bradbury, in his novel Fahrenheit 451, constantly references hands as a symbol for different forms of creativity.
Hello I am Arturo Haces- Garcia I am an 11th grade student at Santa Gertrudis Academy High School, in Kingsville, Texas, and I am interested in developing a project for my local science fair, this project involves using electromyography signals to control servos. The project in question is a Prosthetic forearm, which will move by connecting small muscle electrodes to certain muscles in the face, where certain actions, like blinking, smirking, and frowning will make the arm do a certain moves. Last year I entered the competition, and I reached the State level with my Self Driving Accident Avoiding Car, I also attended the INTEL-ISEF as a Student Observer. I got interested in prosthetics because I love electronics, and want to make
Everyone knows Terry Fox, the man who travelled the world with one leg, but what made his journey possible after he got his leg removed, what gave him the hope to keep going? Good morning/afternoon teachers and classmates, today is the day where you learn about the inspiring technology of prosthetic limbs. Some of you may not even know what a prosthetic is or how it works, but you may have heard of or know about the Paralympics. I see the paralympics as an opportunity for people with prosthetic limbs to show the world that they are not so different, that they can do the same thing as people with natural limbs.
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.
Spinal anesthesia is the most commonly used technique for lower abdominal and lower limb surgeries as it is very economical and easy to administerIntrathecal α2 agonist when used as adjunct potentiates the effect of local anaesthetics and allows a decrease in required doses..

A legend was born on January 31, 1947 in Refugio, Texas. His name is Nolan Ryan. The book Nolan Ryan: The Road the Cooperstown by Nolan Ryan gives many details about his life and many of the difficulties he had. Ryan is married to Ruth Holdorff, and has three kids by the names of Reid, Reese, and Wendy. He currently holds many different pitching records in baseball. His first major league team was the New York Mets in 1965. He was drafted in the twelfth round. Little did he know, that was the start of his twenty-seven year long career as a pitcher. He later on would overcome many injuries and continue his career much longer than he had expected. The pictures on my poster illustrate several aspects of Nolan Ryan’s life.
A ghoul is a being of pure evil, one with no soul, a foul disgusting thing that desires to be the most horrific being it can be like Ivan the Terrible. Ivan the Terrible was the Tsar of Russia from 1533 to 1584. He was a ruthless, cunning evil being who killed and brutally murdered hundreds of thousands of people. The Tsar ordered people to be beheaded, strangled, hanged, blinded, burned, stabbed, boiled, disemboweled, buried alive, impaled, and fried. The Villain would often force parents to watch the execution of their children. When Ivan ordered people to be executed, he would often watch and sometimes his executions would take up to 15 hours. Ivan would often remove people’s ribs with red hot pinchers. Peasant girls were often tortured,

Knowing people can help Vladek survive in these wars.Vladek a Jewish survivor of the Holocaust and WW II used his skill of speaking more than one language.Some people may say that Vladek Spiegelman was not resourceful, but more lucky surviving the WW II and the Holocaust.Vladek’s key to surviving WW II and the Holocaust was being both resourceful and lucky.
The hands are the most complicated part of the arm in structure, having 27 bones (as well as the bone structure in the wrist joint), at the same time as the rest of the arm has only 3 bones. The so much complicated structure of small bones enables the hand a higher degree of elasticity, but it also implies that any injury happened to the hand is very much difficult to deal with, because cracks to these small bones might be not easy to get right, or may has more compilations in surgical treatments.
Vladek fought to survive, at first alone. Vladek deserves the most admirable character award because he was confident, intelligent, and for the entire time, brave. For this, he is admirable.
There are an estimated 1.9 million amputees in the United States and approximately 185,000 amputations surgeries performed each year. (McGimpsey) Many amputees are hit with the reality that they are unable to participate in many physical activities due to their lack of a limb. Science has come up with a way to make it possible for disabled people to walk, run, and jump with prosthetic legs. In the early 70s there were mostly prosthetics that allowed an amputee to pick up and hold things. Scientists and sport enthusiasts began their work to make it possible for more upper body accessibility with prosthetics. Now people can do almost anything just using fake arms.
