Let Me Teach You The Nervous System

Nerve cells are also called neurons. There are 3 types of neurons - sensory, motor and association neurons.

Sensory neurons have sensitive nerve endings called receptors.

Sensory nerves are nerves which pass message to the brain and motor nerves are nerves which pass messages from the brain.

Association neurons are in the brain and the spinal cord. They interpret the messages and pass them on to motor neurons.

Each neuron has a cell body which contains nucleus and strands called nerve fibers.

There are 2 types of fibers –

Dendrites carry information to the cell body and Axons carry information away from the cell body.  The axons of 1 cell joins to another cell’s dendrites or a muscle to pass on information.

Nerves are cords that that contain bundles of nerve fibers  Sensory nerves have sensory neurons and motor nerves have motor neurons. Only mixed nerves have fibers from both. The spinal cord is a thick bundle of nerves, which runs from the brain down in your backbone. Impulses from all parts of the body pass through the spinal cord.

Information moves all along neurons in the form of electrical signals called nerve impulses. When an impulse reaches between one neuron and the next, a chemical called neurotransmitter is released. If enough of this chemical builds up in the next neuron, an impulse is sent on.

There are 2 types of actions – Voluntary and involuntary actions.

Voluntary actions are actions which are under our control like kicking a ball. We are conscious of it.

Involuntary actions are actions which are beyond our control like beating of the heart. We are unconscious about it.

In nervous system both brain and spinal cord pass messages through motor nerves. The spine or the spinal cord only gives messages when there is a sudden action like when you touch a cactus the reflex action is “OUCH”!

Reflex actions are involuntary actions. They are usually sudden movements, such as pulling your hand when you touch something hot. You become aware of them because of the impulses that are sent to the brain to tell you what is happening.

I hope I helped you understand a few things about our nervous system

A Story On Divinity

One day, a simple village boy named Shyam saw a sage praying.

Once the sage finished his prayers, Shyam respectfully asked "O great sage, I would be pleased if you would tell me what it is that you were doing?"  The sage told him that he was praying.

The eager Shyam asked the meaning of prayer. The sage told him "Praying is a way you connect with God”.

The sage then explained that even if a person’s religion or caste differed, it did not matter as the Holy books and God are all One.

Shyam nodded, but politely asked " What does God do? Who is he? And how does He help?

The sage humbly said, “God shows us the true way to knowledge and enlightenment. He is a spirit who has made us and tests us. He teaches us through all the incidents we have in our life.  That is how he helps us.

Shyam's head was full with questions. “Why can't we say all prayers at one time and become enlightened?” he asked.

After hearing this, the sage said “My dear, there are different stages for chanting different prayers. Chanting wrong prayers at the wrong time can cause problems.  We must say the right prayers at the right time.”

“What would happen if the prayers aren't said properly? What would happen then?” asked Shyam. 

“The prayers would have no effect then,” said the sage. “Each of the 108 beads in a mala works on a separate part of your body.”

The sage then said, “The holy book for the Hindus is The Bhagvada Gita, The Bible is for the Christians, The Quran for the Islamic people. They all mean the same. They help our soul grow.”

Then the sage told Shyam that "Spread this message everywhere".

I hope that this story helped you.

What is A Blog ???

A blog (a blend of the term web log) is a type of website or part of a website supposed to be updated with new content from time to time. Blogs are usually maintained by an individual with regular entries of commentary, descriptions of events, or other material such as graphics or video. Entries are commonly displayed in reverse-chronological order. Blog can also be used as a verb, meaning to maintain or add content to a blog.

Although not a must, but most good quality blogs are interactive, allowing visitors to leave comments and even message each other via widgets on the blogs and it is this interactivity that distinguishes them from other static websites.

Many blogs provide commentary on a particular subject; others function as more personal online diaries; yet still others function more as online brand advertising of a particular individual or company. A typical blog combines text, images, and links to other blogs, Web pages, and other media related to its topic.

The ability of readers to leave comments in an interactive format is an important part of many blogs. Most blogs are primarily textual, although some focus on art (art blog), photographs (photo blog), videos (video blogging or vlogging), music (MP3 blog), and audio (podcasting). Micro blogging is another type of blogging, featuring very short posts.

As of 16 February 2011, there were over 156 million public blogs in existence.
