The Human Brain

“The Human Brain”, by myPerspectives, is an informative article that claims that the brain is a complex organ that is truly impressive. The brain is a key part of the central nervous system, that controls the entire body’s activities, to simple things such as breathing. These actions are fired through neurons, that quickly travel through the spinal cord. Surprisingly, the brain transmits these messages at an unimaginable rate, at 150 miles per hour, through 85 billion cells, called neurons. These neurons can form up to 10,000 synapses, or connections to each other. By itself, the brain can create billions of synapses, which change the structure of the brain every time new information is learned. However, there is still much that scientists

Q1: The cerebral cortex is a highly organized, six layered structure (L1-6) with a variety of excitatory and inhibitory cell types. Excitatory (glutamatergic) neurons make up 80% of the cortex and consist of pyramidal and spiny stellate (granule) neurons. Inhibitory (GABAergic) neurons make up only 20% of the cortex and consist of four different subtypes: non-fast spiking serotonin expressing GABAergic neurons, martinotti cells, basket cells, and chandelier cells (Petersen & Crochet, 2013; Shipp, 2007). The total number of neuronal cells in the adult human cortex is 21.4 billion for females and 26.3 billion for males; however, there are also non-neuronal cells present in the cortex (Pelvig, Pakkenberg, Stark, & Pakkenberg, 2008). The major non-neuronal cells are glial cells and consist of: oligodendrocytes (75% of non-neuronal cells), astrocytes (20%) and microglia (5%) (Pelvig et al., 2008). The layering of the cortex is highly organized, with specific cell bodies located in each layer. Layer 1 receives input from other cortical layers as well as subcortical layers and is comprised solely of inhibitory neurons, although there are axons and dendrites that project onto these neurons in addition to non-neuronal cells (Petersen & Crochet, 2013). Layers 2/3 are difficult to differentiate from one another, and often referred to as the supragranular layers. These layers contain medium sized pyramidal cells that have densely packed and highly aligned apical dendrites and make

The brain is made up of neurons. The features that make up the neurons are dendrites which receive signals from other neurons. Another part of the neuron is the axon which holds microfibers that carry information inside the neuron from the detricals to the endpoints of the neurons called terminal branches. The neurons in the brain communicate with one another through neurotransmitters that release chemicals.

Our nervous system is there to help to transfer the things our body feels and what we need. The nervous is broken up into two parts, the central nervous system (CNS), and the peripheral nervous system (PNS). The CNS controls the brain and the spinal cord, the PNS controls the nerves and the ganglia (a small mass of gray matter). Our body uses the spinal cord to send messages to the nerves so that it can control our organs and muscles.

CNS and other parts of you body.

The CNS receives information from all over the body, processes that information, and then sends out messages telling the body how to respond.

Nerve Cells:

Neurons live both in and outside the central nervous system. Understanding how the neurons work is vital to understanding the nervous system. Our nervous systems is responsible for all of Our senses. The nervous controls all actions we do everyday, such as answering the phone, eating the food, and study for things. when we perform this routine act, the individual neurons in our nervous system controls our body to make everything possible. The nervous system has two components: the central nervous system and the peripheral nervous system. The central nervous system is made up of the brain, spinal cord and nerves. The peripheral nervous system consists of sensory neurons, ganglia and nerves that

The brain is a very complex organ that is the center of the nervous system. The brain is able to gather and send information to the rest of the body, which allows living creatures to most effectively live, or survive. The brain is constantly working, even while sleeping or unconscious, to send signals throughout our body. These signals tell us different things such as, when to eat, when to use the restroom, and things as simple as swallowing your spit. The brain is in constant communication.

A lot of people don't realize how crucial the brain is in every task we do, even down to just the slightest movement. The nervous system is responsible for almost all things in your body, “This system is responsible for sending, receiving, and interpreting information from all parts of the body”(Bailey, Regina). This system allows for things such as major organ function and muscle movement. It can go from regulating your body temperature to just moving your fingers, even the movement of your eyes as you read this!

The Nervous system is composed of trillions of neurons/nerve cells that forms a network to serve as communication system for the body. The neurons are able to send electrical impulses from the brain to the body and vice versa, which leads to a response from a person via a coordinated action.

     The brain is aware of its surroundings, via input from the spinal cord and cranial nerves. Cranial nerves with sensory functions allow us to smell and see. Nerves with both motor and sensory functions are responsible for everything from tasting and chewing, to breathing and the heating of your heart. Many of the little things we take for granted are also made possible by cranial nerves.

Neurons also play a part in the control of our behaviour. Like when our brain gives signals to the rest of the body to move via neurons. To move our legs, our legs need a large supply of blood therefore the brain needs to send messages to the heart also. Two parts of the nervous system operate to carry out such movement, the semantic nervous system and the autonomic nervous system. The semantic nervous system controls the skeletal muscles, thus is

The nervous system is in many ways the most vital system of the body. It is responsible for monitoring and regulating homeostasis, coordinating voluntary and involuntary responses and integrating sensory information. Anatomically, it is divided into two sections: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS controls the brain

The human body is complex, and all humans are similar to one another in many ways. As humans we share a lot of characteristics in common with one another, such as having hands, feet, eyes, nose, gender, ethnic backgrounds and etc. There has to be some characteristic or organ we have that differentiate all of us, and all these features we have in common, and that is our brain. The brain is one of the largest and most complex organs in the human body. It is made up more than 100 billion nerves that communicate in trillions of connections called synapses. Synapse is a junction between two nerve cells, consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter. The brain is made up of many

You live and you learn, from the moment that we breathe our first breath, we are assimilating and are acquiring information. Life changing and profound learning experiences happen before we can even speak, as children our learning process is grandiose. Harvard University published a series of summaries on Child development. One of these articles mentions that “The basic architecture of the brain is constructed through an ongoing process that begins before birth and continues into adulthood.” ("InBrief: The Science of Early Childhood Development," n.d.).

The Human Brain is the most important organ in the body. Much like the headquarters of the body. Without the brain the rest of the body will suffer. The brain also creates different traits and personalities. How ever when the brain doesn't function properly it will cause many effects to an individual. These effects can range from minimal to severe, depending on what is wrong with the brain.
