Dental or oral health is concerned with your teeth, gums and mouth. The goal is to prevent complications such as tooth decay (cavities) and gum disease and to maintain the overall health of your mouth.

A healthy mouth, free of infections, injuries and other problems with teeth and gums, is important in maintaining your overall health.

Although a different set of medical professionals focuses on dental health, they are still part of your regular health care team.

Disease and other conditions can affect your dental health and dental problems can affect other parts of your body. Failing to properly care for your oral health may lead to other health problems.

You can help prevent or minimize many oral health problems by regular preventive steps (brushing, flossing and so on) and regular visits to dental health professionals.

Injuries to mouth

Injuries to the mouth and teeth can cause problems, especially for young people playing sports. Make sure young (and not so young) athletes use a properly fitted mouth guard, especially when playing contact sports or engaging is activities where falls and blows to the mouth are possible.

Dental health begins shortly after birth and continues the rest of your life. Constant and consistent oral health habits come from habits and patterns established as children under the direction of a parent.

Good oral health practices and regular visits to dental health professionals will help you enjoy the benefits of a bright smile and a pain-free mouth.

What is a Neurologist?

Introduction to Neurology

Neurology is the branch of medicine concerned with the study and treatment of disorders of the nervous system. The nervous system is a complex, sophisticated system that regulates and coordinates body activities. It has two major divisions:

  • Central nervous system: the brain and spinal cord
  • Peripheral nervous system: all other neural elements, such as eyes, ears, skin, and other “sensory receptors”

A doctor who specializes in neurology is called a neurologist. The neurologist treats disorders that affect the brain, spinal cord, and nerves, such as:

  • Cerebrovascular disease, such as stroke
  • Demyelinating diseases of the central nervous system, such as multiple sclerosis
  • Headache disorders
  • Infections of the brain and peripheral nervous system
  • Movement disorders, such as Parkinson’s disease
  • Neurodegenerative disorders, such as Alzheimer’s disease, Parkinson’s disease, and Amyotrophic Lateral Sclerosis (Lou Gehrig’s disease)
  • Seizure disorders, such as epilepsy
  • Spinal cord disorders
  • Speech and language disorders

Neurologists do not perform surgery. If one of their patients requires surgery, they refer them to a neurosurgeon.

Introduction to the Human Heart

The human heart is one of the most important organs responsible for sustaining life. It is a muscular organ with four chambers. The size of the heart is the size of about a clenched fist.

The human heart functions throughout a person’s lifespan and is one of the most robust and hardest working muscles in the human body.

Besides humans, most other animals also possess a heart that pumps blood throughout their bodies. Even invertebrates such as grasshoppers possess a heart like pumping organ, though they do not function the same way a human heart does.

Position of Heart in Human Body

The human heart is located between the lungs in the thoracic cavity, slightly towards the left of the sternum (breastbone). It is derived from the embryonic mesodermal germ layer.

The Function of Heart

The function of the heart in any organism is to maintain a constant flow of blood throughout the body. This replenishes oxygen and circulates nutrients among the cells and tissues.

Following are the main functions of the heart:

  • One of the primary functions of the human heart is to pump blood throughout the body.
  • Blood delivers oxygen, hormones, glucose and other components to various parts of the body, including the human heart.
  • The heart also ensures that adequate blood pressure is maintained in the body
