The human brain acts as the body’s control center. The brain controls all body systems such as circulatory, nervous, breathing, urinary, integumentary systems, among other systems. It’s at the control center in sending and receiving signals to the body organs through the nervous system and secreted hormones. The brain is as well responsible for our memories, thoughts, feelings, storage, and our general perception of the world.
How does the brain control the body systems? Cardiovascular system case study
The research revealed that the brain has master control center cells controlling the cardiovascular system. These master controller cells orchestrate blood flow to different designated parts. This discovery was published in the Journal of physiology and identified where the cardiovascular issues, for instance, heart failure and high blood pressure are stages managed by the brain.
The researchers used genetically modified viruses in animal models to make brain cells that administrated blood flow supervised by the microscope. This allowed them to trace how these cells were connected to the parts of the cardiovascular system. The brain cells were reported to exert influence on many parts of the body, such as the blood vessels and the heart. This, without a doubt, suggested how the cells coordinated body activities in the cardiovascular system.
The nervous system and Brain
Ideally, the brain control thoughts, feelings, memory, movements, and what we learn and talk. The brain controls all that happens in our bodies, and the nervous system is a network that transmits messages back and forth to body parts. This happens via the spinal cord that runs from the brain through the back down. The nervous system contains thread-like structures branching to every organ of the body.
When the brain receives a message form any body organ, it generates an appropriate response. For instance, touch a hot stove, the skin nerves will shoot a message of pain to the brain then the brain will send a coded message prompting the hand muscles to withdraw or pull away. Fortunately, such neurological relay race happens instant.
Parts of the Brain
The forebrain, midbrain, and hindbrain are the three main subsections of the brain.
This is the complex and most substantial part of the brain consisting of the cerebrum and its structures. The cerebrum is responsible for body memory, intelligence, personality, emotion, speech, and ability to move and feel. The outer layer of the cerebrum is known as the cortex, which receives information from the five senses. In turn, the information is sent to the parts of the nervous system for processing. For instance, touch a hot stove; the experience you get will never allow you to repeat touching again.
The midbrain is located underneath the forebrain and is the master for all the information circulating in and out of the brain to the spinal cord.
The hindbrain is located underneath the cerebrum end, and it consists of cerebellum, medulla and the pons. The cerebellum is responsible for general body balancing, movement, and coordination. On the other hand, medulla and the pons with the midbrain are considered as the brain stem. The brain stem takes in messages and sends them out as well as coordinates the brain information. Besides, it controls many of the body automatic functions such as heartbeat, breathing, blood pressure, swallowing, digestion, and eye blinking.
In summary, when asking yourself what functions does your brain provide your body? The simple answer is that the brain is the master controller of our body activities. The brain controls all the body systems, thereby forming an integral part of our body.
