Brain Structures and Their Functions Brain Structures and Their Functions The human brain is a specialized organ that is responsible for all thought and movement that the body produces.

Learn which part plays what role. The human brain allows humans to successfully interact with their environment, by communicating with others and interacting with inanimate objects near their position.

The functions of the brain

If the brain is not functioning properly, the ability to move, generate accurate sensory information or speak and understand language can be damaged as well. The brain is made up of nerve cells which interact with the rest of the body through the spinal cord and nervous system.

These cells relate information back to specific centers of the brain where it can be processed and an appropriate reaction can be generated. Several chemicals are also located in The functions of the brain brain, which help the body maintain homeostasis, or a sense of overall comfort and calm as its basic needs are met.

Keeping these chemicals balanced and the nerve cells firing properly are essential to healthy brain function. Parts of the Brain and Their Functions Cerebrum The cerebrum is the largest portion of the brain, and contains tools which are responsible for most of the brain's function.

It is divided into four sections: The cerebrum is divided into a right and left hemisphere which are connected by axons that relay messages from one to the other.

This matter is made of nerve cells which carry signals between the organ and the nerve cells which run through the body. The frontal lobe is one of four lobes in the cerebral hemisphere. This lobe controls a several elements including creative thought, problem solving, intellect, judgment, behavior, attention, abstract thinking, physical reactions, muscle movements, coordinated movements, smell and personality.

Located in the cerebral hemisphere, this lobe focuses on comprehension. Visual functions, language, reading, internal stimuli, tactile sensation and sensory comprehension will be monitored here. Sensory Cortex- The sensory cortex, located in the front portion of the parietal lobe, receives information relayed from the spinal cord regarding the position of various body parts and how they are moving.

This middle area of the brain can also be used to relay information from the sense of touch, including pain or pressure which is affecting different portions of the body. Motor Cortex- This helps the brain monitor and control movement throughout the body.

It is located in the top, middle portion of the brain. The temporal lobe controls visual and auditory memories. It includes areas that help manage some speech and hearing capabilities, behavioral elements, and language. It is located in the cerebral hemisphere.

Wernicke's Area- This portion of the temporal lobe is formed around the auditory cortex. While scientists have a limited understanding of the function of this area, it is known that it helps the body formulate or understand speech.

The optical lobe is located in the cerebral hemisphere in the back of the head. It helps to control vision. Broca's Area- This area of the brain controls the facial neurons as well as the understanding of speech and language.

It is located in the triangular and opercular section of the inferior frontal gyrus. Cerebellum This is commonly referred to as "the little brain," and is considered to be older than the cerebrum on the evolutionary scale. The cerebellum controls essential body functions such as balance, posture and coordination, allowing humans to move properly and maintain their structure.

Limbic System The limbic system contains glands which help relay emotions. Many hormonal responses that the body generates are initiated in this area. The limbic system includes the amygdala, hippocampus, hypothalamus and thalamus. The amygdala helps the body responds to emotions, memories and fear.

It is a large portion of the telencephalon, located within the temporal lobe which can be seen from the surface of the brain.

This visible bulge is known as the uncus. This portion of the brain is used for learning memory, specifically converting temporary memories into permanent memories which can be stored within the brain. The hippocampus also helps people analyze and remember spatial relationships, allowing for accurate movements.Anatomy of the Brain Overview The brain is an amazing three-pound organ that controls all functions of the body, interprets information from the outside world, and embodies the essence of the mind and soul.

WebMD's Brain Anatomy Page provides a detailed diagram and definition of the brain including its function, parts, and conditions that affect it. Brain Function, It's a Team Sport The brain is the most complex organ in the body.

It is the organ that allows us to think, have emotions, move, and even dream. Given this complexity, it should not be surprising that there are many ways to separate the parts of the brain. Brain parts can be separated on the basis of what they look like to the. Brain Stem: Underneath the limbic system is the brain stem.

This structure is responsible for basic vital life functions such as breathing, heartbeat, and blood pressure. This structure is responsible for basic vital life functions such as breathing, heartbeat, and blood pressure.

The higher functions of the brain are associated with its higher and more developed region called cerebral cortex that contains four lobes, each assigned a particular task.

The overall activities are accomplished with the division of labor, that is, different parts perform different functions. Brain Stem: Underneath the limbic system is the brain stem.

This structure is responsible for basic vital life functions such as breathing, heartbeat, and blood pressure. This structure is responsible for basic vital life functions such as breathing, heartbeat, and blood pressure.
