Hey! Dr.Zak is here to highlight a new informative article about, "Fastest System in our body". Before I take Start my article, I kinda want to be sorry to BCH Community and Rusty because of mistakes that I always encountered in my Article. I have poor English Grammer Skills but I am learning them from Youtube Tutorials to rectify this deficiency.
Let us start today's article that is related to our body system. First of all, I want to respond and appreciate @Mr_Trenzs on his Article, "What Will happen if we make 100â„… use of our brain?". Dear, First of all, we are not able to use our brain 100% because our Euchromatin material in the nucleus remains condensed Throughout our life. if kinda it gets uncondensed then it means 23 other chromosomes features showed by our body. I am excited to Response one research says due to Phenomenon if happen a man takes control of his death. So God made it condensed so that He will call back to us on our time. I think I respond to ed you in a good way. Any other questions You can ask me.
Now return to today's article, our body is complicated and supported by many Systems. There are the following systems in our body.
1) Digestive system: related to our digestion of food.
2) Urinary System: related to our blood filtration and urine formation.
3) Skeletal System: related to our bones and Muscles and help in Support, movement, and shape.
4) Endocrine System: Related to Glands and hormones.
5) Respiratory System: related to our exchange of gases between lungs and environment.
6) Nervous system: related to neurons and nerves.
etc
These all systems worked in delicate coordination. If one system shuts down all other systems are useless. This is how they are connected and helped each other in making us able to do and perform any activity. We should always say Thanks To God for this great blessing. Now the question is, "Do you Know the Fastest system in our body?". Yeah in the above System, the Nervous System is the fastest of all and it produces a response in a nano-second. I am ready to give you learn more about this System as I have kinda Graduation in medical Sciences. I hope you will enjoy this.
Our nervous system is categorized into two types.
1) Central Nervous System
2) Peripheral Nervous system
Again they both work in coordination for a complete response. Otherwise, we are not able to use any one of them.
1)CNS consists of the brain and spinal cord. Its basic unit is the nerve cell called a neuron. A neuron can be of many types.
1)Motor neuron
2)Sensory Neuron
3) Relay Neuron
All neurons are connected with the brain and spinal cord and perform their different functions within the brain and spinal cord and their outside.
#Origin of Brain
When a baby is born, there is the production of a nerve streak in its skull, this Streak changes into three lobes. The biggest of this lobe is Forebrain, then the hindbrain and the smallest is the mid-brain that functions to interlink the Forebrain and hindbrain. Our brain is a complicated structure. It is just like the Central processing unit of a computer. It controls all the activities of the body. I kinda want to explain its all three parts one by one for your more information.
# Forebrain
The largest part of the brain. It involves many activities occurring in bodies body. I further divider this large part.
1) Cerebrum
2) Thalamus
3) Limbic System
#Cerebrum:
It is the kinda largest part of the whole Forebrain. It can be divided into the Cerebral Cortex and the Cerebral medulla. The cerebral Cortex has many sensory centers where information is analyzed and processed for further details. The cerebral cortex is divided into the Cerebral hemisphere making its right and left parts. Amazingly a man writing from the left hand is using write cerebral Hemisphere and writing with the right hand is utilizing the left cerebral Hemisphere. Some can use both if they can write with both hands. Anyway, these cerebral hemispheres have gaps and these gaps are bridged by thousands of bands of neurons called Corpus Coliseum. The cerebral cortex is involved in Learning as it has a higher brain part. It produces a visual response due to the vision center in it. Thought, sensation, perception, memory, association, and voluntary Physical actions are produced by this part.
#Thalamus
Thalamus is present in almost the center of the brain. It screens all the information and sends it to the cerebral cortex's higher parts. It receives all the sensory information from the body.
#Limbic System
This system is connected to all our emotions, feelings, sexual arousal, punishment, feelings of joy and happiness, rage, and aggressive behavior. It consists of further.
1) Hippocampus
It is present in an arc fashion near to the thalamus. Its main function is to produce new memory.
2) Amygdala
It is connected to all feelings that are related to Happiness and sorrow.
3) Hypothalamus
It is an important part as it changes chemical coordination into nervous Coordination. It controls the Sleep-wake Cycle, Mensuration Cycle, Pattern of breathing, temperature, and monitor glucose level in the blood, etc.
#Mid-brain
It is the smallest part of the brain in humans and the largest part in birds. It makes reticulate information in our brain. It receives information from the hindbrain and sends it towards the forebrain.
#Hind Brain
It is the last part of the brain. It consists of Cerebellum, Pons, and Medulla-oblongata. The cerebellum is related to body balanced motion. It is absent in the butterfly so you can observe its random motion. Pons is related to breathing and sound pattern. Medulla-oblongata is connected with the spinal cord and is involved in many reflexes.
#Brain Stem
Pons, mid-brain, and Medulla-oblongata form the brain stem from where the brain starts.
#Spinal Cord
It has a butterfly structure. Its diameter is equal to our thumb size. It controls all the reflexes of the body. Its dorsal and ventral route has ganglia and sensory and motor nerves.
#Peripheral Nervous System
It produces coordination with CNS and the whole body. It is involved in the control of both emergencies and fight-flight mechanisms. It also controls blood pressure as well. It consists of
1) Sympathetic Nervous system
It prepares the body for emergency conditions. It induces the body for fight or flight mechanisms. Inan n emergency, It inhibits digestion, dilates pupils, and increases heart rate.
2) Parasympathetic Nervous System
It functions to normal back all the systems. It positions back to the pupil, starts digestion, and normalizes heartbeat.
All the essential parts make and produce a response in a nano-second. It was Science relevant but interesting to read you can get any information from this. You can take all the above details through following tutorial Lecture on Youtube.
