Intro of the body, Our mechanism

     In our bodies, there is lots of different things that make it up.  Cells combining to make tissue.  Tissue being used to make our structures.  Certain structures would include the heart, liver, muscles, tendons connecting our muscle to bone, or bone to bone.  Different studies include cytology (study of cells), embryology (study of body when in the womb) and histology (tissue study).  Our bodies in a sense are mechanisms.  They can communicate, do physical tasks, digest fuel, circulate oxygen through it, and send electric currents through the nerve all at the same time.  Theres many different walks of studying the body.
   
     But in analyzing the body for study, we go into anatomical ways of studying it.  Such terms as anterior. posterior, proximal, distal, superior, and inferior to name a few pop up to show different sides/sections of the body.  When dividing the body into cut up sections, you go into scientific terms to describe simple parts of the body.  Instead of right and left side, you would call it sagittal.  "That part lies in the right sagittal area."  Or Medial, which would be smack dab in the middle of the right and left sagittal sections.  Frontal and coronal division is when the front (anterior) and back (posterior) get separated.
     Then the oblique section, a section of nine important parts divided up like a tic tac tow board.  the top right of the "oblique board" is the right hypochondriac region.  Opposite side of course being the left hypochondriac region.  In between those two, is the epigastric region.  these three regions are right below the chest muscles, and right above midway between the belly button and the chest.  Below that is the right and left lumbar, with the umbilical region inbetween the two.  The umbilical region as you might of guessed, includes the belly button towards the bottom of it.  Finally under that layer, is the right and left iliac with hypogastric between those.  Hypogastric includes the top of the pubic region, and just below the belly button. 
     In cytology, you study how cells are layered in different ways in order to make tissue.  Many, many different types of tissue.  Different tissues make up different organs.  But, back to cells, cells can be arranged in different sizes, shapes, and texture. or other wise known as epithilia.  Squamos, very short and fat shaped cells are similar to a checkers set piece.  Cuboidal would be shaped like an alphebet block that young children play with.  A culumnar type of cell would be similar to an unused pencil that is vertically standing upright.  These cells can combine to each other to make different types of tissue.
     If these epithelia are simply combined the simple squamos would look like train cars going down the track.  Short, fat, one strata'd cells combines to each other.  But if they were stratified, then it would be train cars stacked on top of each other.  Strata meaning layers of course.  Simple cuboidal would be when the baby try's to spell out words with his/her alphabet blocks.  But when the baby try's to build a house or a pyramid with the blocks it becomes a stratified cuboidal cell structure.  In a stratified columnar structure, the pencils I was talking about earlier would be stacked on top of each other and some what inner twined as well.
     That is just a short description of what cell structures tend to look like.  I like using analogies to describe what i'm talking about.  I feel that it gives you a pretty good idea of what the cell structures would look like.  Then when a real picture is seen, it binds the memory that much more.
