Nerve and neuron sound similar to most people‚ but they are two different components of the body (Martini‚ 375). Nerves are found only in the peripheral nervous system‚ while neurons are found in the brain‚ spinal cord‚ and peripheral nerve (Martini‚ 375). Neurons are nerves cells that are specialized for intercellular communication (Martini‚ 375). A neuron is composed of a cell body‚ dendrites and axon (Marieb‚ 376). A nerve is a bundle of axons or dendrites that is wrapped in connective tissues

A neuron is a nerve cell in the brain‚ it is essentially the building block of the nervous system. Each neuron is itself a miniature decision making device‚ reacting to signals it receives from hundreds‚ even thousands of other neurons. Each signal is either excitatory or inhibitory. Excitatory signals increase the likelihood of an action potential happening‚ inhibitory make an action potential in a nerve cell less likely. The action potential is a nerve impulse. Once the excitatory signals over

subject of mirror neurons‚ which are neurons that fire when an animal acts or observes the same action done by another. We learned that these neurons exist primarily in the ventral premotor cortex F5 areas of a monkey’s brain. Experiments proved that neurons in the VPC F5 area fire when a monkey does an action‚ but also fire when a monkey watches a human do the same action. However‚ when the monkey watches the human just carry out the motions of the action‚ not actually do it‚ the neurons in this area

(The French Thermidorean reaction refers to the period after the Reign of Terror‚ in 1794‚ when the tyrant Robespierre was removed from power and an economically and culturally liberal government came to power.) This reaction‚ in turn‚ was due to Welch’s less creative‚ more opportunistic and more intolerant leadership during his last years

One source of explanation arose from research on mirror neurons-which fire both during execution and observation of a behaviour (Rizzollati & Arbib‚ 1998). This particular class of neurons plays a crucial function in human social interactions. The importance of the mirror neuron system (MNS) for communication can be understood through its influence on nonverbal communication including facial expressions and hand gestures

Explain the concept of potential output and why actual output can differ from potential output? (2 marks) Potential output is the amount of output that an economy can produce when using its resources such as capital and labour‚ at normal rates. Potential output is not a fixed number but grows over time‚ reflecting increases in both the amounts of available capital and labour and their productivity. As capital and labour can be utilised at greater than normal rates‚ at least for a time‚

How true is the economic mandate that one does not spend others’ money as carefully as spending their own money‚ when it comes to aid practices? Is there an optimal size for a NGO‚ given that bureaucracy tends to become more apparent as a NGO grows‚ which often leads to deviation or inflexibility of the organizational practices and ideals?qq On the intangible

Telemedicine is the use of medical information exchanged from one site to another via electronic communications to improve a patient’s clinical health status. Telemedicine includes a growing variety of applications and services using two-way video‚ email‚ smart phones‚ wireless tools and other forms of telecommunications technology. I believe this is a great way for doctors‚ dentist‚ and any other health care professional to easily get the information that they need quickly. This is a huge time

requires communication between your brain‚ muscles and organs. This starts with the neurons. Our organs sense things the brain needs to know. Signals are sent to the brain‚ it is decoded and then tells your brain what muscles to use and how. The signal is sent‚ a neurotransmitter. This is stored in the axon. An electrical impulse starts in the neuron. The charge is sent down the axon and this is how it starts. A neuron has three basic parts: the body or soma‚ the axon and the dendrites. The Cell

The Neuron Doctrine is a concept that led scientists to the realization that the brain consists of many specialized regions and cells. However‚ during the process‚ scientists had to overcome obstacles such as the minute size of the cell‚ the jello-like consistency of brain tissue‚ and the similar cream- colored pigmentation of tissue cells. Advances in technology over the years‚ though‚ helped to solve these problems: the development of the compound microscope‚ the discovery of how to harden‚ or
