Introduction and General Orientation to Human Anatomy Flashcards
Anatomy
the study of structure
Physiology
the study of function
Inspection
simply looking at the body’s appearance, as in performing a physical examination or making a clinical diagnosis from surface appearance
Palpation
feeling a structure with the hands, such as taking a pulse or feeling a swollen lymph node
Auscultation
listening to the natural sounds made by the body, such as heart and lung sounds
Percussion
the examiner taps on the body, feels for abnormal resistance, and listens to the emitted sound for signs of abnormalities such as pocket of fluid or air
Dissection
the careful cutting and separation of tissues to reveal their relationships
Cadaver
a dead human body
Comparative Anatomy
the study of more than one species to examine structural similarities and differences and analyze evolutionary trends
Exploratory Surgery
opening the body and taking a look inside to see what is wrong and what can be done about it
Medical Imaging
methods of viewing the inside of the body without surgery
Radiology
the branch of medicine concerned with imaging
Gross Anatomy
structure that can be seen with the naked eye - whether by surface observation, radiology, or dissection
Histology (microscopic anatomy)
take tissue specimens, thinly slice and stain them, and observe them under the microscope
Histopathology
the microscopic examination of tissues for signs of disease
Cytology
the study of the structure and function of individual cells
Ultrastructure
refers to fine detail, down to the molecular level, revealed by the electron microscope
Comparative Physiology
the study of how different species have solved problems of life such as water balance, respiration and reproduction
Organism
a single, complete individual
Organ System
a group of organs with a unique collective function
Organ
a structure composed of two or more tissue types that work together to carry out a particular function
Tissue
a mass of similar cells and cell products that forms a discrete region of and organ and performs a specific function
Cells
the smallest units of and organism that carry out all the basic functions of life; nothing simpler that a cell is considered alive
Organelles
microscopic structures in a cell that carry out its individual functions
Molecules
a particle composed of at least two atoms that make up organelles and other cellular components
Atoms
the smallest particles with unique chemical identities
Anatomical Position
a stance in which a person stands erect with the feet flat on the floor and close together, arms at the sides, and the palms and face directed forward
Sagittal Plane
passes vertically through the body or an organ and divides it into right and left portions
Median (Mid-Sagittal) Plane
the sagittal plane that divides the body or organ into equal halves
Frontal (Coronal) Plane
extends vertically but is perpendicular to the sagittal plane and divides the body into anterior (front) and posterior (back) portions
Transverse (Horizontal) Plane
passes across the body or an organ perpendicular to its long axis; it divides the body or organ into superior(upper) and inferior (lower) portions
