Lecture 1 Notes These notes are organized in the same order as the objectives given in the Lecture notes This first set is somewhat short as it will only listcover material that is pertinent for the exams so I ve combined both lecture 1 amp 2 into one set Defining anatomy and Physiology amp Early History 1 Andreas Vesalius published the first modern anatomy textbook titled De Humani Corporis Fabrica Structure of the Human Body First to discover point out that the skeleton is vital to the human body Vesalius contribution was to anatomy 2 William Harvey an English physician discovered the process of blood circulation Specifically that the heart was the pump responsible for pushing blood throughout the body His published work was titled De Motu Cordis et Sanguinis in Animalibus On the Motion of heart and Blood in animals Harvey s contribution was to Physiology Definition of Life For a substance or subject to be defined as a quotliving form it has to be able to replicate The lecture notes have the full comprehensive list of some of the ability that higher life forms have but to name a few moving responding to stimuli reproducing circulating blood etc Biochemical Processes Metabolism 1 Ability to degrade molecules in order to gain energy 2 Ability to synthesize new molecules for the body s structural and functional components Lecture 2 Notes Objective I Essential Human Needs 1 Food Intracellular 2 Water gt 56 human body is fluid lt 339 oxygen Extracellular 4 Warmth Objective ll amp Ill Homeostasis and the Six Factors Homeostasis is essential because it is used to regulate our internal environment 1 Body Temp 2 Oxygen levels in blood and tissues 3 Acidity or alkalinity pH of blood amp body fluids Processes under Homeostatic Control 4 Salt content 5 Glucose level in the blood 6 Metabolic waste product levels Objective IV Negative Feedback Definition process that monitors for extreme deviations from normal limits and takes action if something goes wrong to get conditions stable again Diagram should be memorized Falls to set point Normal Temperature Objective V Body Organization Atoms in our body are organized progressively 1 Molecules 2 Cellswhite blood cells 3 Tissues made up of combined cells 4 Organs groups of tissues 5 Systems groups of organs Objective VI Hox Genes I Rises above set point Normal Temperature These genes are found in most organisms but there are four main groups that control related regions in the human body Essential to the development of the skeleton Also responsible for certain mutations in the human skeleton Objective VII Body Cavities amp Organs 1 Dorsal 2 Ventral cavity Cranial brain Thoracic Vertebral spine Abdominopelvic 3 Small head cavities ora orbita eyes nasa middle ear Objective VIII Membranes associated with Thoracic and Abdominopelvic cavities Thoracic 1 Pleural lines thoracic covers lungs 2 Pericardial surrounds and covers heart Abdominopelvic Peritonea lines abdominopelvic cavity covers organs Objective lXBody Positions I m using the word SCAMPS Superior hold your head high vs being inferior and hanging your head in shame away from the head CenterThe Central Intelligence of the body is in the brain and spinal cord We still need to pay attention to our surroundings outside ie the peripheral Anterior rhymes with interior Watch your step as you come in through the front door or you might land on your posterior Medialm is for middle or midline that one s pretty easy Frankly I don t think lateral riddles are all that funny Proximalanother easy one p is for proximity gt you are close to the body vs being distant or distal Superficial pretty easy it s all about what s on the surface In other words you re not that deep Objective X Planes of the Body 1 Sagittal divides the body into left and right 2 Transverse across horizontal cut superior vs inferior 3 Coronal front vs back ie anterior vs posterior Objective XI Noninvasive vs Invasive Procedure Endoscopes inserted into small body openings or surgical precisions Far less invasive method of surgery called Endoscopy than open surgery which involves larger incisions Invasive body is invaded in some way Noninvasive body is not actually penetrated Ex xrays cat scans etc This is a summary of lectures 1 amp 2 not including the vocabulary list at the end of lecture 2
