MEDICINE IS FUN !!!

MEDICINE IS FUN INTRODUCTION John Backus said, “They don’t like thinking in Medical school. They memorize – that is all they want you to do. You must not think”. Is this really true? Or is it just a mere fallacy? As a Pre-Med or Pre-Clinical student, one of the things you must know is that Medicine is FUN. By FUN I mean, F – Full of Challenges U – Unequivocally Pleasurable N – Not Unassailable. MEDICINE IS FULL OF CHALLENGES This is not a deniable fact. These challenges include but are not limited to the high volume of information that is given to Medical students at a short time frame, so many new vocabulary and terminologies to learn especially in Anatomy, minimal time given during exams and scariness of textbook size. These should not be setbacks, they should rather be stepping stones for you. Success is not a matter of luck; it requires conscious effort to the attainment of your goals. In order to face these challenges you need to do certain things like: • Int...

AUTOSOMAL DISORDERS

By -
PATTERNS OF INHERITANCE IN FAMILIES 1 A pattern of inheritance can be predicted by studying alleles and how they work together to produce traits GENES; these are units of heredity. They contain enough information to produce a complete protein, they control traits expressed in an individual CROMOSOMES; They carry the genes on specific points called loci ALLELES; these are forms or variations of a gene. They occupy the same position on a chromosome i.e same locus and control the same trait but are variations of a trait, so a variation of a gene is an allele of the gene Ø   AUTOSOMAL DOMINANT ALLELE; These are traits that are inherited in a dominant fashion i.e they find expression even if its only present in one copy of the chromosome. These traits are found on the autosomal chromosomes. These traits affect the male and female child equally. Disorders as a result of autosomal dominant allele are rare because the affected people do not live long enough to get to rep...

STEPS INVOLVED IN THE TRIGGERING AND GENERATION OF ACTION POTENTIALS

By -
There are basically 3 steps involved in the triggering and generation of action potential; Generation of  end plate potential; This occurs after the acetycholine has attached to its receptor and now stimulates the opening of certain chemically gated Na/ K channels allowing the movement of these ions. More of the Na ions move into the cell causing a change in potential. this local depolarization established is called an end plate potential Depolarization; This stage involves the generation and propagation of action potential. the end plate potential stimulates the opening of certain voltage gated Na channels leading to the influx of more Na ion  increasingly until certain voltage - the threshold voltage has been overcomed and action potential is generated. This action potential is propagated in all direction stimulating futher opening of other voltage gated Na channels  Repolarization; This stage involves the restoring of the sarcolemma to its normal polarized state. ...
