ch 1 class Flashcards
define dissection
careful cutting apart of body structures to study their relationships
define anatomy and physiology
anatomy: study of body structures and their relationship among structures
physiology: study of the body functions
name some branches of anatomy
developmental biology, embryology, cell biology, histology, gross anatomy, systemic anatomy, regional anatomy, surface anatomy, imaging anatomy, clinical anatomy, pathological anatomy
what is developmental biology
branch of anatomy, the growth and development of an individual from fertilization to death
what is embryology
branch of anatomy, first 8 weeks of growth and development after fertilization of a human egg; earliest stage of developmental biology
what is cell biology
branch of anatomy, cellular structure and functions
what is histology
branch of anatomy, microscopic structure of tissues
what is systemic anatomy
structure of specific systems of the body
what is regional anatomy
specific regions of the body (head, chest)
what is surface (topographical) anatomy
surface markings of the body to understand internal anatomy through visualization and palpation (gentle touch)
what is imaging anatomy
internal body structures that can be visualized with techniques such as x-rays, CT scans, MRI
what is clinical anatomy
application of anatomy to the practice of medicine, dentistry, and other health-related sciences
what are some branches of physiology
molecular physiology, neurophysiology, endocrinology, cardiovascular physiology, immunology, respiratory physiology, renal physiology, exercise physiology, and pathophysiology
what is molecular physiology
functions of individual molecules such as proteins and DNA
what is neurophysiology
functional properties of nerve cells
endocrinology
functional properties of hormones (chemical regulators in the blood)
cardiovascular physiology
functions of the heart and blood vessels
immunology
body’s defence against disease-causing agents
respiratory physiology
functions of the air passageways and lungs
renal physiology
functions of the kidney
exercise physiology
changes in cell and organ functions due to muscular activity
pathophysiology
functional changes associated with disease and aging
what are the six levels of structural organization
chemical, cellular, tissue, organ, system and organismal
explain the chemical level of structural organization
- atoms (C, H, O, N, P, Ca, S) join to form larger molecules
- the 4 macromolecules in our body are proteins, lipids, carbohydrates and nucleic acids
explain the cellular level of structural organization
- cells are the basic structural and functional living units of an organisms
-smalled living units in the human body
-stem cells differentiate to become specialized cells with different functions
explain the tissue level of structural organization
-tissues are groups of cells and the materials surrounding them that work together to perform a particular function
explain the organ level of structural organization
- organ: composed of two or more different tissue types
- have specific functions and usually have recognizable shapes
