Recently it has been claimed to function as a Biological clock regulating day and night periodicity.

Essay on Human Brain: Structure and Function

Internal injuries may involve the skull, the blood vessels within the skull, or the brain. Specific body parts like the tongue or fingers are mapped onto certain areas of the brain including the primary motor cortex.

Its cavity is called diocoel or third ventricle. It is formed of grey matter and contains millions of neurons.

Your lips, in turn, require about as much dedicated brain processing as all of your fingers and your hand combined! Besides looking at the brain as an organ that is made up of two halves we can also examine it by looking at its four various lobes of the cerebral cortex, the outer part of the brain see Figure 5.

Brain and Nervous System

The pons and the medulla, along with the midbrain, are often called the brainstem. These structures are important in producing the neurotransmitteracetylcholinewhich is then distributed widely throughout the brain.

The cerebral hemispheres the left and right hemispheres that make up each side of the top of the brain are in charge of the types of processes that are associated with more awareness and voluntary control such as speaking and planning as well as contain our primary sensory areas such as seeing, hearing, feeling, and moving.

Covering the inner parts of the brain is the cerebral cortex, which consists of two cerebral hemispheres. This means that the left side of the brain is responsible for controlling a number of sensory and motor functions of the right side of the body, and vice versa.

Some of the signals carried by the PNS are related to voluntary actions. In another method the hands stroke near the acupuncture channels: This electrical part of the signal, called an action potential shoots down the axona long tail that leads away from the soma and toward the next neuron. The cerebral cortex is highly convulated in order to increase its surface area.

These include the nucleus accumbensnucleus basalisdiagonal band of Brocasubstantia innominataand the medial septal nucleus. For example, if you accidentally touch a hot stove, the nerves in your skin shoot a message of pain to your brain.

Hind brain or Rhombencephalon Fore Brain: With the addition of gentle movement and stretching extra oxygen is demanded from the blood, which may help to reduce the presence of hydrogen ions and initiate a swing toward a more anabolic level of activity.

The rare split-brain patients offer helpful insights into how the brain works.

The aspects of Qigong and Yoga that quiet the mind and relax the body induce a neurotransmitter profile that is conducive to healing.Each brain hemisphere is specialised and dominates the various other in certain functions. This dominance relates to whether one is right-handed or left-handed.

Generally in most right-handed people, the left hemisphere processes arithmetic, vocabulary, and speech. The Central Nervous System (CNS): The Neurons inside the Brain Figure 1: The central nervous system The Central Nervous System, or CNS for short, is made up of the brain and spinal cord (see Figure 1).

The Brain and Nervous System The nervous system is broken down into two major systems: Central Nervous System and Peripheral Nervous System. We’ll discuss the Central Nervous System first. First, observe how the brain is divided into two hemispheres.

The left side of the brain is the analytical side, helping with logic, math, and speech, and it controls the right side of your body.

The human brain is the central organ of the human nervous system, and with the spinal cord makes up the central nervous system. The brain consists of the cerebrum, the brainstem and the cerebellum.

How the Nervous System Works. The basic functioning of the nervous system depends a lot on tiny cells called neurons. The brain has billions of them, and they have many specialized jobs.

For example, sensory neurons take information from the eyes, ears, nose, tongue, and skin to the brain.
