Alpha motor neuron

In my opinion, the human body is one of the most complex mechanisms known to mankind – even more complex than the latest iPhone X. The human body comprises of many different systems: the digestive system, the endocrine system, the exocrine system, the muscular system, the urinary system, the reproductive system, the respiratory system, the circulatory system, the sympathetic system, the skeletal system. The human body consists of about 300 bones at birth and this number decreases to 206 by…

Football and boxing is a contact sport, indiviuals are getting hit in the head a lot. It is very dangerous. It is very dangerous because, it is bad for indiviuals health.Also, males or females can develop permanent brain damage. However parents and children do not take it serious until something happens to them, or to their child. Studies show, "While much of the health and safety debate over football and other contact sports focuses on the risk of developing severe, headline-grabbing…

It also represents a sense organ, such as an eye. The nervous system also contains neuroglial or glial cells which are not neurons and usually outnumber the neurons at a ratio of 10 to 1. The typical peripheral glial cells surrounding the axons are referred to as Schwann cells and are useful in myelination. The microglia, oligodendrocytes, and astrocytes form the central glia and are associated…

cells called neurons, alongside supporting cells. The human brain contains 1010 to 1012 neurons (1). Neurons have a distinct cell shape and range from microns up to a millimeter in length. Neurons’ unique structure allows for rapid and specific transmission of signals along a neuron, and from one neuron to another. Neurons transmit nerve impulses over long and thin axons, and receive information through branches of dendrites. Although neurons are a diverse set of cells, most neurons share…

“Don’t wait, not everyone gets the time I’m getting” (Albom 166). This was said by Morrie Schwartz. Morrie had a disease called ALS, ALS (also known as Lou Gehrig’s disease) is a disease that affects the nervous system, weakening the muscles and affects how the body functions. It’s slowing taking over his body, even he is dying and his time is limited, he takes the time he has left to make things right with people. Not everyone realizes that they had the time to live the life the right way until…

SCIENCE ENGINEERING TECHNOLOGY MATHEMATICS By Teanah Bautista and Izak Ford BIOLOGY OF HEARING The hearing is a quite a significant piece of creation used by humans. The complex organization of bones, hair, and cells it captures vibrated sound waves and processes to the brain. With everything happening almost instantly. But it's not as easy as it sounds. The sound is invisible vibrated particles through the air. The moving vibrations cause the air around to also vibrate creating sound waves…

the nervous system are Nervous Tissue, Brain, Spinal Cord, Nerves, Sense Organs, and the Cerebrospinal Fluid. The nervous tissue is the main tissue of the central and peripheral nervous system. This tissue conducts nerve impulses and is composed of neurons. The brain sends messages to the spinal cord the peripheral nerves all over the body that serve to control organs and muscles. The spinal cord is a long…

Within the past month, the topic of pornography has come into the public eye with the state of Utah declaring it a public health crisis. For some this came as a shock and offense but to me it was only a matter of time. I have experienced first hand the effects of how pornography use before and sporadically during a relationship negatively affects the relationship. From this I can tell you that when I knew my significant other had viewed porn it hurt me, my self-esteem, my sense of security, and…

The Tale of the Dueling Neurosurgeons written by Sam Kean is a collection of stories throughout history that depicts the discovery, symptoms, and shifts in the fundamental understanding of the brain and brain injuries. Within the pages of this book, Kean does a masterful job explaining the intricacies of the brain, providing captivating stories to stimulate the reader, all while encapsulating valuable information on the brain. The book is written from a scientific perspective, invoking brain…

manipulated in order to elucidate the receptive fields of the electrosensory neurons of the lateral line lobe. The experiment described above involving the Eigenmannia in a two-compartment chamber apparatus allows researchers to identify the approximate location of the neuron’s receptive field responding to amplitude modulations (Heiligenberg 1987). In order to identify the approximate location of the receptive fields for neurons that are responding to phase modulations, a different, more…
