The human brain is made up of 100 to 150 billion neurons. The folds of these neurons on the surface of the brain, often referred to as gray matter, allow for an increase in surface area, giving humans more space for cognitive processes. The brain...
The central nervous system, which consists of the brain, spinal cord and nerves, controls every function in the body. The brain is divided into three parts: the forebrain, the midbrain and the hindbrain, each of which is further divided into...
According to the National Institute of Mental Health, approximately 1 percent of the U.S. population is diagnosed with schizophrenia. Schizophrenia has no exact known cause but is categorized as a brain disorder affecting the balance in...
The brain, sitting atop the spinal column, controls everything a person does, whether the functions classify as voluntary, such as standing up or running, or involuntary such as breathing and having a heartbeat. The brain itself consists of...
The brain is a complex organ. It controls and regulates everything your body does. The human brain is divided into sections. Each section is responsible for various functions such as breathing, speaking, vision and so forth. At the back bottom...
The human brain is an extremely complex organ which, among many other things, controls blood pressure and heart rate, interprets the senses, initiates body movement, and is the home of emotions and intelligence. The adult human brain weighs about...
Your brain and body work in conjunction to produce the movements needed for exercise. Exercise requires select muscle contractions to provide the coordinated movements necessary for activities such as running, walking, jogging, swimming, skating...
The human brain, or encephalon, is composed of the forebrain, the midbrain and the hindbrain. The forebrain includes the cortex, the latest to appear in evolutionary development, and deeper structures. The cortex is responsible for the higher...
There are three main structures that make up the brain. These include the cerebrum, cerebellum and the brainstem, explains the Brain Explorer site. Within each of these main structures are several smaller, but very important parts. The brain is...
The human brain is part of the body’s central nervous system; in conjunction with the spinal cord and nerves, it controls everything that the body does. The main functions of the brain are controlled by three of the brain structures: the...
Physicians grade brain tumors according to their degree of malignancy. One aspect of a tumor's appearance that affects its grade is whether it is diffuse--with no clear edge or margin--or focal--with a clear margin defining where it begins and...
The human brain can be anatomically divided into three main sections, or layers. The outermost part is called the forebrain (the prosencephalon); the middle layer is called the midbrain (the messancephalon); and the innermost part of the brain is...
The human brain weighs about 3 lbs. and contains 100 billion neurons and even more glial cells, according to Neuroscience For Kids, a University of Washington website. The brain has three major divisions, which contain different structures and two...
The brain and spinal cord make up the central nervous system. They process information presented by sensory receptors located all over the body and execute appropriate responses. Different regions of the brain are responsible for integrating...
The nervous system is comprised of three primary structures: the brain, spinal cord and nerves. Together, these systems control all aspects of the body from simple movements to solving complex calculations. The spinal cord and nerves play vital...
The brain is considered to be the most complex organ and system of the human body. It averages, according to Neurosurgery Today, 2.7 pounds for women and 3 pounds for men. The brain is the seat of all interpretive sensory experience, thought and...
The brain is a complex structure that is composed of different structures and tissues. According to the National Institutes of Neurological Disorders and Stroke (NINDS), the brain has three major parts: prosencephalon, mesencephalon and...
The human brain is a complex organ that weighs three pounds. It holds intelligence, interprets sensations, controls behavior and initiates body movements. It has different interdependent parts that work together to perform all of the intricate...
The brain is located in the cranial cavity inside the cranium, or skull, and makes up the central nervous system along with the spinal cord. Beneath the bony surface of the cranium, three layers of tough connective tissue called the dura mater,...
Your brain is an amazing structure that coordinates all voluntary movements, involuntary movements and plays a role in your vision, emotions and storage of memories. Your brain must constantly process information coming from within your body as...
The brain is an amazing organ that weighs about 3 lbs. and is encased in a protective layer of bone called the skull. The brain is the central feature of the human body, and adds dimensions such as personality and emotions to life as well as...
The human brain is an exquisitely complex and highly organized organ. The forebrain, midbrain and hindbrain comprise the three functional regions of the brain. Within each region, individual lobes and structures exist, which control specific...
According to the U.S. Department of Health and Human Services, 51.6 percent of Americans over the age of 12 reported themselves as alcohol drinkers in 2008. The National Institute of Alcohol Abuse and Alcoholism (NIAAA) has reported what we all...
Making up the central nervous system are the brain, spinal cord and the peripheral nervous system. The highly complex brain is the center of the nervous system, in charge of the body. According to the National Institute of Neurological Disorders...
The term "hand-eye coordination" describes the ability of your body's visual system to process information received through the eyes and use it to direct the movements of the hands. Tennis, golf, baseball and basketball players obviously require...
The most complex organ in the body, the brain, is made up of a hundred billion neurons communicating with each other. This single organ is divided into three distinct parts with some regions responsible for more than one function. To date,...
The brain is far more than a 3-pound single entity housed beneath the skull. The brain is divided into three sections, each controlling a number of brain functions. Each area of the brain is important for full human functioning. In much of the...
Chiari malformation refers to a condition in which the brain doesn't fit into the back part of the skull and so gets squeezed down into the top part of the spinal canal. Some people don't have symptoms, but others experience headaches and other...
The brain contains three main parts: the forebrain, the midbrain and the hindbrain. The cerebrum is the largest part of the brain. Located in the forebrain, it is divided into the frontal lobe, parietal lobe, occipital lobe and temporal lobe. The...
