Topic 1 - Intro to Anatomy

Question 1

define anatomy

Answer 1

the study of internal and external structors of the human body. how all organisms work together in an organismal fashion.

Question 2

describe the divisions of anatomy

Answer 2

gross anatomy: all that can be seen with the naked eye
mirco-anatomy: a microscope is necessary in all instances such as cytology; to see in depth one specific cell. or histology; to see the four tissues. (cant be seen with a naked eye).

Question 3

describe in order from simplest to most complex the order and levels of organization of the human body

Answer 3

chemical: atoms, tiny building blocks, form together creating molecules such as water and proteins. molecules then form together creating organelles and in turn there are blood cells. *cells are the most basic function of life.
cellular: as cells are made up of molecules such as H20 and O, molecules form organelles which form life. this leads to the next level; tissue
tissue: there are four tissue types; epithelial (covers body surface), connective tissue (protects organs), muscular (allows movement) and nervous (notifies the mind and body with a rapid electrical impulse). these tissues are groups of similarly structured cells coming together to accomplish a common function.
organ: two or more tissues used, typically four, that work together to accomplish a common function amongst other organs in the body. eg. respiratory system: use of lungs, branchi, oesophagus… function is respirating.
organism: organ system consists of multiple organs that work together closely
organismal: the human body is made up of many organ systems that work closely together to maintain life!
