Chapter 1-Intro to Anatomy Flashcards
What is Anatomy?
The science of structure; relationships revealed by dissection
What is Physiology?
The science of body functions; how the body structures function
Subdivisions of Anatomy
surface anatomy, gross anatomy, systemic
anatomy, regional anatomy, radiographic
anatomy, developmental anatomy, embryology,
cytology, and pathological anatomy
Subdivisions of Physiology
cell physiology, systems physiology,
pathophysiology, exercise physiology,
neurophysiology, endocrinology,
cardiovascular physiology, immunophysiology,
respiratory physiology, renal physiology, and
reproductive physiology
Structural Organization of Matter
- Chemical Level
a. Atoms
b. Molecules - Cells
- Tissues
- Organs
- Organ System
What are the types of Atoms?
Protons, Neutrons, and Electrons
What are Molecules?
Two or more atoms joined together by either covalent or ionic bonds
Four biologically important organic molecules in the human body
- Proteins
- Complex Carbohydrates
- Nucleic Acids
- Lipids
What are Proteins made of?
20 different Amino Acids
What are complex carbohydrates made of?
Simple sugars (glucose, monosaccharides, disaccharides, etc.)
What are Nucleic Acids made of?
Nucleotides
What are Lipids made out of?
Fatty Acids and Glycerol
The smallest structural and functional units of the human body
Cells
Tissues are made of?
Groups of cells and the materials surrounding them that work together to perform a particular function
What are Organs made of?
Composed of two or more tissues work together to provide specific functions and they usually have specific shapes
What makes an organ system?
Consist of one or more organs that provide a common function
Examples of Organ Systems
a. Integumentary system
b. Skeletal system
c. Muscular system
d. Nervous system
e. Endocrine system
f. Cardiovascular system
g. Lymphatic system
h. Respiratory system
I. Digestive system
j. Urinary system
k. Reproductive system
What is Metabolism?
Sum of all biochemical processes of cells, tissues, organs, and organ systems
What is Responsiveness?
Ability to detect and respond to changes in the internal and external environment
What is the basic life process of Movement?
Occurs at the intracellular level, cellular, and organ levels
What is Growth?
Increase in the number of cells, size of cells, tissues, organs, and the body. Single cell to a multicellular complex organism
What is Differentation?
Process a cell undergoes to develop from an unspecialized cell to a specialized cell
What is Reproduction?
Formation of new cells for growth, repair, or replacement, or the production of a new individual
What is Homeostasis?
Equilibrium of the body’s internal environment produced by the interaction of organ systems and regulatory processes (feedback systems)
Homeostasis is a dynamic condition in response to changing systems
