Chapter 1 Systems Flashcards
Inspection
The first non-invasive technique observation of the body
Auscultation
To listen to body sounds to evaluate function of certain organs, often with stethoscope
Palpation
To touch, feel surface with hands
Noninvasive diagnostic technique
One that does not involve the insertion of an instrument or device through the skin or into a body opening
Percussion
examiner taps on the body surface with finger tips and listens to the resulting echo
Atoms
The smallest unit of matter
Molecules
Two or more Atoms joined together
Chemical level
Atoms and molecules smallest units of matter compared like the letters of the alphabet at the chemical level
Cellular level
Molecules combined to form cells
Cell
Basic structural and functional units of an organism composed of chemicals
Tissue level of structural organization
Groups of cells and materials surrounding them that work together to perform a particular function
Frontal
Coronal
The chemical level Of structural organization
Includes Adams the smallest units of matter that participate in chemical reactions and molecules which are two or more Adams joined together this is the chemical level
What is the tissue level of structural organization
Groups of cells and materials surrounding them that work together to perform a particular function similar to the way words are put together to form a sentence
What is the organ level of structural organization
The organ level, two or more different types of tissues are joined together similar in the relationship between sentences and paragraphs organs are structures that are composed of two or more different types of tissue and usually have a recognizable shapes and specific functions
What is the system level of structural organization in the body also called organ system level
The system consists of related organs with common function such as a Digestive system which breaks down and absorbs food includes organs like the mouth salvary glands throat esophagus stomach small intestine large intestine liver gallbladder pancreas
The organismal level of structural organization in the human body
All the parts of the human body function together constitute the total organism the largest organizational level is the organismal level
Anatomy
Study of the structure of the body and body parts and their spatial relationships to one another
Physiology
The functions of a particular organ or structure even at the cellular or molecular levels
Gross anatomy
Study of large body structures visible to the naked eye
Regional anatomy
Study all the structures in the body region ; head, thorax, foot etc.
Systemic anatomy
Organ systems
Surface or topographical anatomy
Studying internal body structures as they relate to the overlying skin surface
Microscopic anatomy
Use of a microscope
Histology
Study of tissues
Cytology
Study of cells
Developmental anatomy
From conception to old age
Embryology
Study of process of development from conception to birth
