CELLULAR PHYSIOLOGY - 1

Image
 The cell is the basic and most fundamental structure of the human body. It contains all the things required for the functioning.  A cell is basically the command centre. Millions of such command centres gather together to form an organism. The 1st cells to form are the stem cells. They form the basis of the human body. There are various properties of stem cells that include pluripotency, multipotency, nullipotent and totipotency.   This video shows the mitotic division of the stem cell. Note the mitotic spindle formed that leads to division. As the zygote further grows the fundamental properties of cell become more potent. This is where the cells decide their functions and behave as they are. This property of cell is called as differentiation; a process where the cell takes up a particular function or cells of particular function gather up to perform a function later turning into a tissue and organ. This event generally happens in the 2nd and 3rd week of intrauterine life (or the peri

  Ever wondered what is this pattern? Some of have seen this pattern get zoom into and then repeating itself from the small outgrowths present and it continues as if there is no end to this.. This is called as the MANDELBROT Set. This set is characterised by a set of complex numbers that come in the equation of  , which does not diverge if z=0, i.e. for the function f(0) and so on. For each value of c the set becomes more stable. and thus sometimes cannot remain stable. There is something common between the reproduction of the population, a leaking tap water, and the human heart beats and neuronal transmission. The amount of times a population can grow is just a multiplication factor, for instance if u know that the population of rabbits double every year then u can easily predict the population next year. If u plot the graph of population of this year and next year, u get an inverted parabola (something similar to shown in graph below). Now if u know the growth factor u can always kno

Neurosurgery - Telovelar approach

Image
 Telovelar approach is carried out for the removal of any pathology that is present inside the 4th ventricle or the rhomboid fossa of the brain. The Space seen here behind the cerebellum is the rhomboid fossa (Fossa is just a trench or a channel). This rhomboid fossa forms a part of the 4th ventricle, which is connected to the third ventricle above by cerebral aqueduct and then runs downwards into the spinal cord as the central canal of the spinal cord, carrying the CSF (CerebroSpinal Fluid). The part behind the PONS and between the white core of cerebellum is called as the 4th ventricle. {For more information on anatomy of brain, please refer to our another blog on BRAIN}

Rape - Medical point of view.

  RAPE Note: This post is only for educative purposes and giving the information regarding the legal aspect of RAPE. Please do not take it lightly because it is a sensitive subject and a very difficult one for all of the citizens of the country as well as the rest of the world. Hope you will learn something important from this post. Also, this post might be disturbing for someone who are sensitive. Reading is not advised for such people, but if they want to read no problem (but still read at your own safety). RAPE, A condition which is psychologically more devastating than the physical damages done. It is a crime of highest order inflicted on the human body. To understand rape, we must know about various types of unnatural sexual offences or practices carried out, just to get sexual satisfaction. Unnatural Sexual methods are those which involve any other interaction other than natural peno-vaginal route. These are some of the unnatural sexual perversions which are done in order to obta

Bizarre yet amazing !!!!!

 Have you ever wondered to be in a place where you are superior! Or a place where there is no other person equivalent to you because of the Superpowers you have? Well, there are certain medical conditions which present with these manifestations and are thus very interesting to study, yet bizarre and rare that few cases exist. Werner's Syndrome -   Named after the German Scientist - Otto Werner. He observed 4 children with premature aging and thus noted this down in 1904. It is one of the rare diseases with global rate of 1 in 100,000 live births. Although this is common in countries like Japan with expected incidence rate of 1 in 20,000 - 45,000. The average life expectancy can be estimated up to 45-50 years and death may be occurring in average age of 50-54 years of life. This means that the maximum a person can live is up to 50 years and above. Since aging is accelerated, the main cause of death is either cardiovascular compromise or any type of malignancy (cancer). People pr

PARKINSON'S

Image
Parkinson's is the second most common neurodegenerative disease. It is named after an English physician who first recorded it in with a detailed description in 1817, named James Parkinson. The risk factors for Parkinson's - Age, Genetic history, Male gender, shyness, depression, any environmental exposure like herbicides, or magnesium and iron exposure, etc. Classification of Parkinson's -  1. Classical - Genetic, sporadic, Lewy body with dementia 2. Atypical - Multiple system atrophy, Cerebellar type,  corticobasal ganglionic degeneration, frontotemporal dementia 3. Secondary Parkinson - Drug induced, tumor associated, liver failure, Normal pressure hydrocephalus, toxins like Carbon monoxide poisoning, cyanide poisoning, etc. How it is caused? Parkinson is a disease which is mainly involved with the BASAL GANGLIA of the brain. Basal Ganglia consist of - Globus pallidus - external and internal Thalamus Subthalamic nuclei Caudate nucleus Putamen Substantia nigra These struct

OCD - Obsessive Compulsive Disorder

Image
OCD or Obsessive Compulsive disorder is a type of disease where you see 2 components together at same time. Obsessions are intrusive, recurrent, unwanted thoughts or ideas that are difficult to dismiss, despite of their disturbing nature. Compulsions are repetitive behaviours, which can be mental or observational, that reduce anxiety by leading to obsession. Women develop OCD more than Males, and generally occur from the age of puberty. Some cases have been reported of OCD manifesting in as early as 2 years of age. OCD is known to occur with other disorders as well, most commonly, OCD tends to co-exist with depression.  Obsessions can be - Contamination, Symmetry, Aggressive, Sexual, Somatic, etc. Compulsions can be - Checking, Washing, Confessing something, Symmetry, Counting, etc. The factors that cause OCD is still unknown, But generally these factors are assumed to cause OCD -  Genetic Environmental Psychological Neurobiological Neurobiological factors include - neuroimmunity, neur
