Chapter 1 Flashcards
What are anatomy and physiology?
Anatomy and Physiology (A & P) are about human structure and function—the biology of the human body
what are the four ways of examining structure of the human body?
- Inspection
- Palpation
- Auscultation
- Percussion
Describe Inspection.
Visual Examination of the body or looking at the body
Describe Palpation.
Feeling the body with fingers or hands
Describe Auscultation.
Listening to sounds, usually with a stethoscope
Describe Percussion.
Producing sounds, usually by tapping on specific areas of the body
What are some ways of studying human anatomy.
- Medical Imaging (Radiology)
- Gross Anatomy
- Histology
- Histopathy
- Cytology
- Ultrastructure
Describe gross anatomy?
Study of structures that can be seen with the naked eye
Describe Histopathology?
Microscopic examination of tissues for signs of disease
Describe Cytology.
Study of structure and function of cells
Describe Ultrastructure
View detail under electron microscope
What are some subdisciplines of Anatomy and Physiology?
- Neurophysiology (physiology of nervous system)
- Endocrinology (physiology of hormones)
- Pathophysiology (mechanisms of disease)
Describe Neurophysiology?
Physiology of nervous system
Describe Endocrinology
Physiology of hormones
Describe Pathophysiology.
Mechanisms of disease
Describe comparative physiology.
Study of different species to learn about body functions (comparing and contrasting)
- Basis for much of our understanding of human physiology and the development of new drugs and medical procedures
What is a Scientific Fact.
Information that can be independently verified
Describe the Law of Nature.
- Generalization about the way matter and energy behave
- Results from inductive reasoning and repeated observations
- Written as verbal statement or mathematical formula
Describe Theory.
An explanatory statement or set of statements derived from facts, laws, and confirmed hypotheses
Who is Charles Darwin?
He is primarily known as the architect of the theory of evolution by natural selection.
Describe Evolution?
Change in genetic composition of population of organisms; Example: development of bacterial resistance to antibiotics
Describe how evolution works.
Through Natural Selection
How does Natural Selection occur?
- Selective pressures
- Adaptations
Describe how Adaptations promote evolution.
Adaptations are inherited features of anatomy and physiology that evolved in response to pressures and that enable organism to succeed; example: better camouflage
Describe how selective pressures promote evolution.
Selection pressures are forces that promote reproductive success of some individuals more than others; example: predators
Considering the hierarchy of complexity of life, which of the following levels is the most complex?
Organisms
