Dendrites Are Important. These Tiny, Little Nerve Cells

space occupied by only three pints of milk yet includes components that, laid end to end, would stretch several hundred thousand miles? What looks like an oversized walnut made of soft, grayish-pink cheese but contains the equivalent of 100 trillion tiny calculators? What, according to James Watson, co-discoverer of the helical structure of DNA, is "the most complex thing we have yet discovered in our universe"? To all four of these intriguing questions there is but one surprising answer: the human

Injury). The spinal cord is an immensely fragile part of the body, it contains a bundle of nerve fibers that connect the brain to the rest of the body. Since the spinal cord is exceptionally fragile it has to be protected by something hard, like the vertebral column. The brain, spinal cord, and the vertebrae is considered the central nervous system, whereas, the peripheral nervous system is formed when the nerves that enter and exit the spinal cord (Boyce). When the spinal cord, brain, or vertebral column

Site Plan | I. Neurons/nerve cells A neuron is a cell specialized to conduct electrochemical impulses called nerve impulses or action potentials. Neuron is the main cellular component of the nervous system, a specialized type of cell that integrates electrochemical activity of the other neurons that are connected to it and that propagates that integrated activity to other neurons. They are the basic information processing structures in the CNS.

4: HUMAN PHYSIOLOGY CELLS AND TISSUES This is a diagram of an animal cell with all its key components labelled The structures within an animal cell are described as follows: Plasma Membrane or Cell Membrane: This is a thin membranous layer which surrounds the cell and acts as a barrier, it works to separate the contents within the cell from its external environment as well as from other cells. It 's structure is important as it provides structural

“According to doctors in the early 20th century anyone over the age of 65 who marked a sign of confusion was diagnosed with Alzheimer’s disease (AD) (Bair, 5).” AD is form of dementia. “It is also a progressive neurodegenerative disorder with a mean duration of around 8.5 years between onset of clinical symptoms and death (ncbi.nlm.nih.gov).” The medicine and science related to dementia and AD specifically has evolved a long way to develop strategies to encourage the healthy altitude of the brain

most important. Other natures are adaptive/nature or acquired/innate, secondary/primary, passive/active, humoral/cell mediated and some parts or antigen specific. Antigen specific means when it recognizes certain antigens it will act upon them. Some pats are systemic which is the don't just stay at the infected area but go through the body and they have memory, so when they come the same antigen again they know, they will attack it even stronger. The non-self/self recognition is every cell has

The Study of Anesthesia: History, Chemistry, and Activity By Cordell Jones The Description of Anesthesia, It’s Effects, its Careers, and it’s Future By Cordell Jones Introduction In 1591, a young mother was dragged from her home and taken away. Her mercy pleas were ignored, and she was thrown intro a pit and buried alive. What was this mother’s crime? She had given birth to twin sons, and during her labor she had asked for some pain relief. The Church regarded the

You just pick one or two a night to discuss while you eat with your family. You can change the slips weekly to focus on a lesson. Another aspect to create positive feelings during dinner is to invite your kids to share any kind deed or tiny act of goodness they did that day. This includes a smile, a kind word or a helping hand. Compliment them on that. Sharing the good they did and being recognized for it helps kids feel happier. It also trains them to notice other's needs and develop empathy.  My

mood and your appetite. Who hasn’t indulged in a pint of Ben and Jerry’s for emotional reasons? What you may not know is that emotional eating is not purely psychological. It’s actually deeply rooted in a biological response controlled by a very important chemical messenger manufactured in the brain and gut: serotonin. Some scientists have coined it the “feel good chemical,” but research has proven that this neurotransmitter is responsible for so much more than a natural high. Serotonin at the Cellular
