A Glance into the Human Brain

A Glance into the Human Brain – Structure and Functions of the Human Brain (Human Brain’s Anatomy and Physiology) – A Voyage Into the Human Brain!

This article describes the structure of human brain (anatomy of human brain) and functions of human brain (physiology of human brain), which is the most complex and mysterious organ of the human body. This article is expected to cater the needs of a variety of audiences including the students, teachers, healthcare professionals, and the laymen. The article has been written in an easy-to-understand language and richly annotated with definitions of difficult medical terms including etymologies.
   

The human brain is the most sophisticated organ of the human body, and can aptly be called as a biological marvel. The brain and the spinal cord constitute the central nervous system (CNS). The brain plays the role of the control tower or control center of the human body, and relies on a vast network of nerves (bundles of fibers of nervous tissue carrying impulses) spread throughout the body. Nerves can be compared to the electrical wiring as they carry electrical impulses.

Noteworthy Facts about the Human Brain!

  • The brain of human beings resembles a small cauliflower in its size and appearance.
  • Human brain is comprised of about 100 billion neurons or nerve cells.
  • The weight of an adult human brain is about 1300 g (about 3 pounds), whereas the weight of a newborn’s brain lies in the range of 350 – 400 g.
  • Although the brain of a human being accounts for only 2 % of the total body weight, it utilizes 20 % of the of the resting total body oxygen consumption.
  • Human brain contains 77 to 78 % water, 10 to 12 % lipids, 8 % proteins, 2 % soluble organic substances, 1 % carbohydrates, and 1 % inorganic salts.
  • The cerebral cortex forms 77% by volume of the human brain.
  • Cerebrum is the largest part of the human brain, whereas Cerebellum is the second largest.
  • Left side of the brain (left cerebral hemisphere) controls the right side of the body, whereas the right side of the brain (right cerebral hemisphere) controls the left side of the human body.

Branches of Biology Depict Its Essence in Diversities!!


Rational and Earnest Thoughts from an Earnest Scientific Mind for All the Readers with the Same Mind – Aditya Sardana aka Adidarwinian –


Science is the study of the Facts; Facts mean the Pure Truths.

Biology is a Complete and Pure Science; Biology is the Pure Truth.


Science studies and describes facts and the facts mean all those things that are pure truths. Biology is a complete science, and therefore, it automatically becomes a pure truth.


As I am a hard-core biologist, I will before answering the question “What is Biology”, like to clarify that Biology is in itself a complete scientific platform on which are based a multitude of Applied Biological Sciences such as Biotechnology, Bioinformatics, Bioengineering, Medicine, Physiotherapy, and plenty of others.

Bioinformatics and Charles Darwin – Biological Approach of the New Age

Bioinformatics and Charles Darwin – Biological Approach of the New Age (updated 27 December, 2014)

Bioinformatics and Charles Darwin – adidarwinian

Great Great Great – It’s For Mr. Darwin Once Again!!

Continue on the radical path paved by the greatest biologist ever born – Charles Darwin – How can an evolutionary biologist do that?

Bioinformatics, sometimes known as Computational Biology, is presently the best way to study the ever interesting field of evolutionary biology. Bioinformatics provides many unique and powerful tools to study evolutionary biology. One such tool that I would like to mention here is PHYLIP (the PHYLogeny Inference Package).

PHYLIP is a free software package which consists of many simple yet powerful programs for inferring phylogenies. PHYLIP can be easily downloaded through the Internet.


Classification of the Programs in the PHYLIP package   

Programs included in the PHYLIP package can be enlisted by the type of data or by the type of algorithm used.

Based On The Type Of Data – DNA sequences; Protein sequences; Distance matrices; Quantitative characters;  Restriction sites; Discrete characters; Tree plotting, consensus trees, tree distances and tree manipulation; and Gene frequencies

Based On The Type Of Algorithm – Branch-and-bound tree search; Heuristic tree search; Interactive tree manipulation; Converting data, making distances or bootstrap replicates; and Plotting trees, consensus trees, tree distances
