Brain Anatomy And Functions

Connecting the brain to the spinal cord the brainstem is the most inferior portion of our brain. Many of the most basic survival functions of the brain are controlled by the brainstem.

Bacteria in the Brain.

Brain anatomy and functions. The brain is one of the largest and most complex organs in the human body. Functions of this area include sneezing vomiting swallowing and movement of the eyes and mouth. Besides relaying sensory and motor signals the structures of the brain stem direct involuntary functions.

The brain and spinal cord are the two main structures of the central nervous system. To breath to control blood pressure and to release hormones. The medulla handles respiration digestion and circulation and reflexes such as swallowing coughing and sneezing.

It is made up of more than 100 billion nerves that communicate in trillions of connections called synapses. Anatomy of the Cerebrum The brain is the major part of every persons central nervous system CNS and the cerebrum is the largest portion of the brain. View and Print Infographic.

1 The cerebral cortex is what we see when we look at the brain. The brain is a dense organ with various functional units. The anatomy of the brain is complex due its intricate structure and function.

The pons helps control breathing rhythms. The main function of the pons is to connect the cerebellum to the rest of the brain and to modify the respiratory output of the medulla. Bacterial infections can make their way to the brain where they can linger undetected.

The pons is the origin of several cranial nerves. The cerebral cortex is the part of the brain that functions to make human beings unique. We will discuss each part separately but keep in mind that they are all interconnected and work together.

Brain Anatomy and Functions. Brain stem works together to regulate essential life functions including body temperature breathing heartbeat and blood pressure. Understanding the anatomy of the brain can be aided by looking at it from different organizational layers.

Brain the mass of nerve tissue in the anterior end of an organism. The brain is a unique organ that is responsible for many functionssuch as problem-solving thinking emotions controlling physical movements and mediating the perception and responses related the five senses.

The pons is the rounded brainstem region between the midbrain and the medulla oblongata. Alcohol 4 Alzheimers Disease 6 Anatomy 233 Amygdala 9 Auditory Cortex 3 Basal Ganglia 3 Brainstem 3. This amazing organ acts as a control center by receiving interpreting and directing sensory information throughout the body.

In higher vertebrates it is also the centre of learning. Brain is the maximum responsible of the thinking and motion the body generates. The study of the anatomy of the brain is neuroanatomy while the study of its function is neuroscience.

Brain Anatomy Function Brain Anatomy and Function Bacteria in the Brain Bacterial infections can make their way to the brain where they can linger undetected. The medulla oblongata the pons and the midbrain. Distinctly human traits including higher thought language and human consciousness as well as the ability to think reason and imagine all originate in the cerebral cortex.

In addition the brain stem coordinates the fine movement of the face and limbs. The two hemispheres of the cerebrum reside in the skull above the brainstem also called the mid-brain and the cerebellum at the very back or bottom of the brain. There are three major divisions of the brain.

Numerous techniques are used to study the brain. They coordinate specific functions including visual memory such as facial recognition verbal memory such as understanding language and interpreting the emotions and reactions of others. The many nerve cells of the brain communicate with each other to control this activity.

In this lesson well discuss the principle brain regions layers of the brain and lobes of the brain as well as common terms used to orient neuroanatomical discussions. In fact pons means bridge in Latin. The brain integrates sensory information and directs motor responses.

The brain consists of many parts that function as an integrated wholeThe major parts are the medulla pons and midbrain collectively called the brain stem the cerebellum the hypothalamus the thala-mus and the cerebrumThese parts are shown in Fig. Physiological functions of human brain involves in reception of information from the body understanding it through cognitive process and guiding the bodys reply. The human brain also mediates in vital actions such as.

The human brain weighs approximately 14 kg 3 pounds and is made up of billions of cells called neurons. The brainstem is made of three regions.
