Brain: Function and Anatomy, Conditions, and Health Tips

What is the brain?

The brain is an organ that ’ south made up of a large mass of nerve tissue that ’ sulfur protected within the skull. It plays a character in just about every major body system. Some of its independent functions include :

  • processing sensory information
  • regulating blood pressure and breathing
  • releasing hormones

Anatomy and function

Cerebrum

The cerebrum is the largest separate of the brain. It ’ mho divided into two halves, called hemispheres. The two hemispheres are separated by a groove called the great longitudinal crevice. The corpus callosum connects the two hemispheres, frankincense allowing the brain to deliver messages from one side to the other. Each hemisphere of the cerebrum is divided into wide 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 cerebellum is located in the back of the brain, barely below the occipital lobe. It ’ s involved with ticket motor skills, which refers to the coordination of smaller, or all right, movements, specially those involving the hands and feet. The cerebellum besides helps the body maintain its position, equilibrium, and libra .

Diencephalon

The diencephalon is located at the base of the genius. It contains the :

  • thalamus
  • subthalamus
  • epithalamus
  • hypothalamus

The epithalamus serves as a connection between the limbic arrangement and other parts of the mind. The limbic organization is a function of the brain that ’ s involved with emotion. The hypothalamus processes information that comes from the autonomic anxious system. Its character includes controlling eating, dormant, and sexual behavior. Some particular actions the hypothalamus is creditworthy for include :

  • maintaining daily physiological cycles, such as the sleep-wake cycle
  • controlling appetite
  • regulating body temperature
  • controlling the production and release of hormones

Brain stem

The brain stem is located in front of the cerebellum and connects to the spinal anesthesia cord. It ’ s creditworthy for passing messages to respective parts of the body and the cerebral cerebral cortex. It consists of three major parts :

  • Midbrain. The midbrain helps control eye movement, processes visual and auditory information, regulates motor movements, and is involved in arousal and wakefulness.
  • Pons. This is the largest part of the brain stem. It’s located below the midbrain. It’s a group of nerves that help connect different parts of the brain. The pons also contains the start of some of the cranial nerves. These nerves are involved in facial movements and transmitting sensory information, as well as breathing.
  • Medulla oblongata. The medulla oblongata is the lowest part of the brain. It acts as the connection between the brain stem and spinal cord. It also acts as the control center for the function of the heart and lungs. It helps regulate many important functions, including motor and sensory functions, breathing, sneezing, and swallowing.
