Human brain diagram

• It receives information from the inner ear's balance system, sensory nerves, and auditory and visual systems. It is involved in the coordination of movements as well as motor learning. • It is also associated with motor movement and control, but this is not because the motor commands originate here. Instead, the cerebellum modifies these signals and makes motor movements accurate and useful. • The cerebellum helps control posture, balance, and the coordination of voluntary movements. This allows different muscle groups to act together and produce coordinated fluid movement. • In addition to playing an essential role in motor control, the cerebellum is also important in certain cognitive functions, including speech. The Amygdala The amygdala is a cluster of nuclei located close to the base of the brain. It is primarily involved in functions including memory, emotion, and the body's The structure processes external stimuli and then relays that information to the hippocampus, which can then prompt a response to deal with outside threats. The Thalamus Located above the brainstem, the thalamus processes and transmits movement and It is essentially a relay station, taking in sensory information and then passing it on to the cerebral cortex. The cerebral cortex also sends information to the thalamus, which then sends this information to other systems. The Hippocampus The hippocampus is a structure located in the temporal lobe. It is important in memory and learning and is somet...

Cerebrum The The two hemispheres are separated by a groove called the great longitudinal fissure. The corpus callosum connects the two hemispheres, thus allowing the brain to deliver messages from one side to the other. Each hemisphere of the cerebrum is divided into broad regions called lobes. Each lobe is associated with different functions: • Frontal lobes. The frontal lobes are the largest of the lobes. As indicated by their name, they’re located in the front part of the brain. They coordinates high-level behaviors, such as motor skills, problem-solving, judgment, planning, and attention. The frontal lobes also manage emotions, personality, and temper. • Parietal lobes. The parietal lobes are located behind the frontal lobes. They’re involved in organizing and interpreting sensory information from other parts of the brain. • Temporal lobes. The temporal lobes house the auditory cortex. They are located on either side of the head on the same level as the ears. They coordinate specific functions, including hearing, visual memory (such as facial recognition), verbal memory (such as understanding language), and interpreting the emotions and reactions of others. • Occipital lobes. The occipital lobes are located in the back of the brain. They’re heavily involved in the ability to read and recognize colors and shapes. Cerebellum The The cerebellum also helps the body maintain its posture, equilibrium, and balance. Diencephalon The diencephalon is located at the base of the b...

Previous 1 of 8 Your brain contains billions of nerve cells arranged in patterns that coordinate thought, emotion, behavior, movement and sensation. A complicated highway system of nerves connects your brain to the rest of your body, so communication can occur in split seconds. Think about how fast you pull your hand back from a hot stove. While all the parts of your brain work together, each part is responsible for a specific function — controlling everything from your heart rate to your mood.

What is the brain? The brain is a complex organ that controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger and every process that regulates our body. Together, the brain and spinal cord that extends from it make up the central nervous system, or CNS. What is the brain made of? Weighing about 3 pounds in the average adult, the brain is about 60% fat. The remaining 40% is a combination of water, protein, carbohydrates and salts. The brain itself is a not a muscle. It contains blood vessels and nerves, including neurons and glial cells. What is the gray matter and white matter? Gray and white matter are two different regions of the central nervous system. In the brain, gray matter refers to the darker, outer portion, while white matter describes the lighter, inner section underneath. In the spinal cord, this order is reversed: The white matter is on the outside, and the gray matter sits within. Gray matter is primarily composed of neuron somas (the round central cell bodies), and white matter is mostly made of axons (the long stems that connects neurons together) wrapped in myelin (a protective coating). The different composition of neuron parts is why the two appear as separate shades on certain scans. Each region serves a different role. Gray matter is primarily responsible for processing and interpreting information, while white matter transmits that information to other parts of the nervous system. How does the brain work? The brai...

Human Brain The human brain controls nearly every aspect of the human body ranging from physiological functions to cognitive abilities. It  functions by receiving and sending signals via neurons to different parts of the body. T he human brain, just like most other mammals, has the same basic structure, but it is better developed than any other mammalian brain. Table of Contents • • • • Read on to explore the human brain structure, diagram, parts of the human brain and the body functions controlled by the human brain. Also Read: Find out how some people live with just half a brain. The Human Brain On average, an adult brain weighs between 1.0 kg – 1.5 kg. It is mainly composed of neurons – the fundamental unit of the brain and nervous system. Recent estimates have suggested that the brain contains anywhere between 86 billion to 100 billion neurons. The brain, along with the spinal cord, constitutes the central nervous system. It is responsible for thoughts, interpretation and origin of control for body movements.

The skull consists of 22 bones, 14 of which form the facial bones and the remaining 8 form the cranial bones. Anatomically, the brain is contained within the cranium and is surrounded by the cerebrospinal fluid.

The brain connects to the spine and is part of the central nervous system (CNS). The various parts of the brain are responsible for personality, movement, breathing, and other crucial processes that keep people alive. An average adult brain weighs The brain is made up of three main parts, which are the cerebrum, cerebellum, and brain stem. Each of these has a unique function and is made up of several parts as well. Keep reading to learn more about the different parts of the brain, the processes they control, and how they all work together. This article also looks at some ways of maintaining a healthy brain.
