As we all know, the brain is a part of the central nervous
system (CNS). Along with the spinal cord and the peripheral
nervous system (PNS), it constitutes the decision-making and
communication center of the body. From breathing to memorizing
facts, the complex network of the CNS controls every part of our
daily life – many of which we are not even aware of. The spinal
cord is a bundle of nerves that acts as an expressway that
receives information from the sensory nerves and transmits them
to the brain. The brain deciphers and translates messages that
it receives and signals to the motor neurons to convey a
response to the concerned organ. The brain develops from a
neural tube of ectodermal tissue in the embryo. The anterior
portion or the forebrain develops from the anterior part of the
neural tube. It is comprised of two hemispheres and is also
known as the cerebrum. The midbrain is the middle portion and
the hindbrain is the posterior portion of the brain that
includes the cerebellum and the brainstem. Und
