Anatomy Book Notes for Exam 1: August 23, 2011 Chapter One: -Function cannot be separated completely from structure. -Obvious structure-function relationships: tight connections between the bones of the skull that protects the brain. The shape of the external ear assists in the collection and localization of sound waves, which facilitates hearing. -Not obvious structures- passageways that carry air into the lungs branch extensively when they reach the lungs. -Histology- microscopic structure of tissues -Six levels of organization of the human body: -Chemical level: (letters of the alphabet) includes atoms (C-carbon, H-hydrogen, etc), which are the smallest unit of matter that participates in chemical reactions and the most essential for life and molecules (DNA), which are two or more atoms joined together. -Cellular Level: (assembling letters into words) molecules combine to form cells. In the body there are muscle, nerve and blood cells. Cells- are structures composed of chemicals and are the basic structural and functional units of an organism. -Tissue Level: (words are put together to form sentences) Tissues- groups of cells and the materials surrounding them that work together to perform a particular function. 4 different types of tissues: -Epithelial tissue- covers the surfaces, lines hollow organs and cavities, and forms glands. -Connective tissue- connects supports, and protects body organs while distributing blood vessels to other tissues -Muscular tissue- contracts (shortens) to make body parts move and generates heat. -Nervous tissue- carries information from one part of the body to another. -Organ level: (sentences to paragraphs) different types of tissues are joined together. Examples are stomach, heart, liver, lungs and brain. Organs- structures that are composed of two or more different types of tissues; they have specific functions and usually have recognizable shapes. -System level (organ-system level)- (like chapters) consists of related organs with a common function. It is like the digestive system and how it breaks down and absorbs food. The organs within the digestive system are the mouth, salivary glands, pharynx, etc. Sometimes an organ is Part of more than one system. -Organismal level- (known as the book) largest organizational level. All the parts of the human body functioning together can constitute the total organism. Anatomical Position -prone: the body is lying face down -supine: the body is lying face up
