Axon

daylight and don’t pay as much attention to the amount of light as rods do. The rods and cones are connected to specialized neurons called bipolar cells, which in turn hook up with the ganglion cells. The ganglion cells lead out of the eye and their axons from the optic nerve, which is the messenger from an eye to the brain. After the nerve fibers leave the eye they separate and some cross to the other side of the head. The optic…

The human body is a complicated thing. No one realizes what all goes through the mind just to do a simple task. The different anatomical features in the human body are many as are the physiological aspects in which all of these various organs and nerves work together. There are many types of tissues that come together make up the four main systems in the human body. These systems intertwine and jointly work together for a person to eventually phonate, breathe, or just walk around a room. The…

The brain is the most complex part of the human body. It is also the most powerful organ of the human body, although it only weighs approximately three pounds (Alzheimer’s Association, 2012). The brain is responsible for all thought and movement that your body produces. The complexity of the brain allows humans to interact with their environment and communicate successfully with others. The brain is not just one huge organ, it has numerous small divisions that enable humans to thrive and survive…

and peripheral nervous system that are linked with one another to create sensations throughout the body. The Central Nervous system is made up of the brain and spinal cord, while the Peripheral Nervous system consist of nerves that are enclosed in axon that connect the Central system to the rest of the body. Both the brain and the body can transmit signals from to the other, however, the names differ depending what does the sending. Nerves that send signals from the brain are called motor nerves…

puffer fish. Tetrodotoxin affects all excitable tissues, nerves and muscle, by binding to the sodium ion channels and preventing sodium to get into the cell. This will affect conductivity of nerve and prevent action potential from traveling down the axon. Without action potential reaching the neuromuscular junction no neurotransmitters will be released and transferred to the muscle and no muscle contraction will occur. On top of that tetrodotoxin affects sodium channels inside muscles which also…

Football Concussions Helmets were not always standard gear until after World War II, some pioneering players wore primitive head covering as far back as the early 1900s. The earliest versions were made of soft leather and were designed to cover the ears. The flaps on the original head harnesses covered the ear completely. They were ridiculed for hindering communication on the playing field. The first helmets offering full protection of the skull and featuring holes in the earflaps were…

Summary Dr. Marshall had dinner with puffer fish and rice during his trip to Indonesia. Not even an hour later, he suddenly felt numbness in his lips, tongue, face and neck. Dr. Marshal also had a feeling of nausea and acutely vomiting because of the pains in his stomach and throat. He was immediately rushed to the ED. His symptoms are diaphoresis, motor dysfunction, parethesias, nausea, ascending paralysis, cyanosis, and hypoventilation. He was prescribed with atropine due to the bradycardia.…

Once the brain structure itself has formed in the womb, nerve cells called neurons begin to form (Broderick & Blewitt, 2010). The brain sends information to the rest of the body through neurotransmitters that are housed in terminals at the end of axons (Sylwester, 1995). Sylwester gave an interesting analogy of how neurotransmitters communicate information. Sylwester explained that receptors are like a lock and neurotransmitters are like a key. Neurotransmitters are a specific…

Adolf Hitler AKA Trump Hitler is described as an idealist, Dictative, Radical, and persuasive person. Hitler was a very hopeful leader at the time. He was a great orator, but his ideals of what was right and what he thought was Germany's destiny were obviously misconstrued. He was very vengeful at the Jews (mother's death), and he was very Idealistic in the fact that he wanted to create a "Pure" Race, a "breed" of man that would be the ultimate in everything, he definitely brought Germany up…

They are made up of different types of nerve cells, which all have an axon which is a long stem-like part of the cell which relays potential signals to the following cell. It organises and controls many of the body’s activities. It also helps to stimulate muscle contraction, makes the body aware of its surroundings and environment…
