The Brain: The Most Complex Organ In Human Body

Great Essays
Anatomy of cerebral cortex:
Brain is most complex organ in human body. The ability of brain for its functioning normally is manifestation of various activities it takes participation in various activities of day to day life, being it hidden from the view or perceptible, like walking, smelling, thinking, laughing, speaking, and hearing. These manifestations are results of very coordinated and complex electrical and chemical activity within and between the cells those makes up our brain. Abnormal functions in the brain may cause hampering the normal functioning of a person. So, it’s very important to understand the basic formation of a human brain to demystify the epileptic seizures.
The human brain constitutes three main structures: the cerebrum or cerebral hemispheres, the

It is a system of tubes, vesicles and sacs, made up of the cells similar to those are around the neurons. Their two types rough and smooth are two different entities and are separated from each other. Large numbers of ribosomes are bound to the surface of Rough endoplasmic reticulum. Under the prescription for sequence of the steps by RNA released by the nucleus of the cell, Rough endoplasmic reticulum makes large segments of protein molecules. These protein segments are moved down through endoplasmic reticulum for assembling, and when completed, these segments are released into ribosome lacked smooth endoplasmic reticulum. These segments are further transported by it to Golgi Apparatus.
f) Polyribosomes: These free ribosomes are several in numbers and attached by a thread. This cluster of ribosomes is referred as Polyribosomes. And the thread is a single strand of mRNA (messenger RNA). These ribosomes in an association make multiple copies of same protein in protein

Ribosomes 3) Ribosomes are non-membrane- bounded particles that float free in the cytoplasm or it is usually attached to the rough endoplasmic reticulum (ER).

    Summary: In the article “Brainology”, Dweck talk about two types of attitudes or mindsets. The two types are a growth mindset and a fixed mindset. Students with a growth mindset tended to get up again from setbacks and continuously improve academically with added effort, while those with a fixed mindset had a mindset that their abilities is what they are stuck with, they are afraid to further challenge themselves; due to belief that they aren't capable. Dweck had concluded that praising one without any acknowledgement of effort tended to create a fixed mindset while those praised for hard work or effort were more likely to not only feel more confident but still kept trying even if a task was a challenge, making these qualities a growth mindset,…

    Cells rely on ribosomes when they need to produce more protein. They are found in all living cells and they host protein synthesis. They can occur as free particles in prokaryotic and eukaryotic cells and also attaches to the membranes of endoplasmic reticulum in eukaryotic cells. When it comes to size, ribosomes are roughly spherical and usually measure 200 angstroms in diameter. To get an idea of how small this is, imagine trying to pick one little speck of dirt in your yard.…

    Seizure-Alert and Response Dogs “A service dog is a canine service animal that generally serves a single individual with a physical or mental disability” (Ensminger definitions xi). SEIZURES AND EPILEPSY “Epilepsy is a neurological disorder characterized by repeated occurrences of seizures” (Varsavsy et al. 313). Seizures can cause a person to fall, shake, walk, or lose consciousness (Fetty 7). “The symptoms of epilepsy are very diverse and these depend on the region of the brain that is affected. An abnormality may cause seizures the via the same mechanisms, but affect the epileptic person differently depending on its location” (Varsavsy et al. 13).…

Its genome is partitioned into three segments, termed (large)L, (medium)M and (small)S. With L about 6,400 nucleotides in length, M about 4,200 nucleotides in length, and S about 1,900 nucleotides in length. L encodes for the viral polymerase, M encodes for structural glycoproteins and S encodes for nucleoproteins (kuhn,Bebermeyer & Hartmann-Klosterkotter , 2005). Pathogenesis…

    Then the signal sequence is then cut from the polypeptide chain. Then the vesicles holding the protein bud from the rough endoplasmic reticulum move too nearby Golgi apparatus. Then the vesicles from the rough endoplasmic reticulum join at one end, adding their proteins to the first flattened vesicle. Then the small vesicle buds from this structure move the proteins to the next layer of the stack.…

    These go about as a boundary to keep DNA inside the core where interpretation happens. The RNA produced amid interpretation is transported out through atomic pores. Numerous proteins are integrated at the Endoplasmic reticulum. The ribosomes tie to the ER (a film bound organelle) and make an interpretation of the RNA message into protein that either navigates the layer (like a protein channel does) or is inside the ER in a vesicle (for solvent proteins that are emitted by the cell by exocytosis... like development elements and hormone proteins) (Meiner,…
