In biology , the nervous system is a highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body. The nervous system detects environmental changes that impact the body, then works in tandem with the endocrine system to respond to such events.

William E. Skaggs , Scholarpedia. The nervous system is the part of an animal's body that coordinates its behavior and transmits signals between different body areas. In vertebrates it consists of two main parts, called the central nervous system CNS and the peripheral nervous system PNS.

It isresponsible for maintaining the membrane potential of theneuron, and it contains ion channels through which ions can flow. Eachcollateral may split into telodendria which end in a synapticknob, which contains synaptic vesicles — membranous bags ofNTs.

A lack of serotoninat postsynaptic neurons has been linked to depression. Inside the fascicle are agroup of axons bathed in endoneurial fluid. The nerve is then wrapped in themain epineurium From one end of a neuron to the other end.

Understanding how cells in the nervous system exhibit fine communication at the synapse level is crucial to elucidating principles underlying fine control in biological systems. The development and maintenance of precise synapses requires inhibitory mechanisms to prevent excessive neuronal inputs. Impaired inhibition of synapse formation is implicated in serious neurological conditions including autism spectrum disorder and intellectual disability.

Routing of signals to one of several alternative circuits, amplification of certain signals while reduction of others, integration of signals from diffuse sources, learning etc, are performed by? Under the condition of disturbed permeability of surface membrane of axon the nerve impulse will. An impulse will travel through a nerve fibre only if the membrane becomes more permeable to ions of. A synpase at which local currents resulting from electrical activity flow between two neurons through gap junctions joining them is called. During conduction of an impulse, electric potential on inside of axolemma plasma membrane of axon changes from. Each cell in resting stage is in polarized state with a membrane potential of. The alkaline and lymph-like serous fluid present inside the cavity of brain and spinal cord is called.

The nervous system is responsible for our thoughts, our emotions, our senses, and our movements. The brain, nerves, and spinal cord are all members of this important process. How much do you know about the nervous system? Do you know what happens when the system malfunctions? Find out by taking this multiple-choice quiz.

Танкадо пишет, его партнер отвечает. - Убедительно.  - Сьюзан нахмурилась.

Они буквально пожирали ее тело. Новая волна паники охватила Сьюзан. Хейл всей тяжестью своего тела придавил ее ноги, холодно следя за каждым ее движением. В сознании Сьюзан промелькнуло все то, что она читала о приемах самозащиты. Она попыталась бороться, но тело ее не слушалось.

 Мы выстрелили в него новым Джей-23, это нервно-паралитическое вещество продолжительного действия. Конечно, это чертовски болезненно, но нам нужно было его остановить. - Не волнуйтесь, мадам, - заверил второй агент.  - С ним все будет в порядке.

Явный звук шагов на верхней площадке. Хейл в ужасе тотчас понял свою ошибку. Стратмор находится на верхней площадке, у меня за спиной.

Мидж изумленно всплеснула руками. - И там и там уран, но разный. - В обеих бомбах уран? - Джабба оживился и прильнул к экрану.  - Это обнадеживает: яблоки и яблоки. - Чем отличаются изотопы? - спросил Фонтейн.  - Это должно быть что-то фундаментальное.

Бледная, жуткая в тусклом свете мониторов фигура застыла, грудь шефа тяжело вздымалась. - Ком… мандер! - вскрикнула она от неожиданности.  - Хейл в Третьем узле. Он напал на. - Что. Этого не может. Он заперт внизу.

Коды, с которыми столкнулось агентство, больше не были шифрами, что разгадывают с помощью карандаша и листка бумаги в клетку, - теперь это были компьютеризированные функции запутывания, основанные на теории хаоса и использующие множественные символические алфавиты, чтобы преобразовать сообщение в абсолютно хаотичный набор знаков. Сначала используемые пароли были довольно короткими, что давало возможность компьютерам АНБ их угадывать. Если искомый пароль содержал десять знаков, то компьютер программировался так, чтобы перебирать все комбинации от 0000000000 до 9999999999, и рано или поздно находил нужное сочетание цифр. Этот метод проб и ошибок был известен как применение грубой силы. На это уходило много времени, но математически гарантировало успех. Когда мир осознал возможности шифровки с помощью грубой силы, пароли стали все длиннее и длиннее. Компьютерное время, необходимое для их угадывания, растягивалось на месяцы и в конце концов - на годы.

Synopsis: Geert Hofstede has completely rewritten, revised and updated Culture's Consequences for the twenty-first century, he has broadened the book's cross-disciplinary appeal, expanded the coverage of countries examined from 40 to more than 50, reformulated his arguments and a large amount of new literature has been included. The book is structured around five major dimensions: power distance; uncertainty avoidance; individualism versus collectivism; masculinity versus femininity; and long term versus short-term orientation.
