Introduction Flashcards
What is the science dealing with animals and all aspects of animal life?
Zoology
What are the four aspects taken up in zoology?
1) structure, function, and embryonic development; 2) nutrition, health, and behaviour; 3) heredity and evolution; and 4) relationship between animate and inanimate environment
What is the study of structures?
Anatomy
This means “to cut”
“ana”
What are the three subdivisions of anatomy?
Gross Anatomy, Developmental Anatomy, Microscopic Anatomy
What is another name for developmental anatomy?
Embryology
What is another name for microscopic anatomy?
Histology
What is the study of functions?
Physiology
What are the four subdivisions of physiology?
Cellular Physiology, Comparative Physiology, Endocrinology, Neurology
What are the eight subdivisions of zoology?
Anatomy, Physiology, Genetics, Ecology, Zoogeography, Paleontology, Taxonomy, Evolution

Conchology
Took interest in animals (as pets, source of food, recreation, games, etc.)
Pre-historic Man
Learned how to domesticate cattle, sheep, pigs, cats, geese, and ducks
Egyptians
Father of Zoology
Aristotle
Who is Galen?
1) first to experiment and make dissections to determine structure and function; 2) made important discoveries on the function of the brain; and 3) the first to state that arteries carry blood not air
Who pointed out inaccuracies in Galen’s description of the human body?
Andreas Vesalius
Who is the Father of Anatomy?
Andreas Vesalius
Who discovered the circulation of the blood and the atrio-ventricular contraction?
William Harvey
Who were the two people responsible for the development of the compound microscope?
Jansen (1950) and Galileo (1610)
Who was the first to describe the presence of cells in plant tissue?
Robert Hooke
Who was the first to describe bacteria, protozoa, and sperms?
Leeuwenhoek
Who is the father of taxonomy?
Linnaeus
Who is the father of embryology?
Karl Ernst von Baer
He was the first to investigate the origin of structure from the three germ layers.
Karl Ernst von Baer
They were the pioneers of comparative anatomy of animals.
George Cuvier and John Hunter
“Cells are the basic units of structures in plants and animals and that organisms are aggregates of cells that are arranged according to definite laws.” Who said this?
Schleiden and Schwann
“All cells can come from pre-existing cells.” Who said this?
Rudolf Virchow
It is the body of knowledge and concerns the laws governing patterns in nature (cause-effect relationships).
Science
What is the scientific method?
A method of research in which: 1) a problem is identified; 2) relevant data are gathered; 3) a hypothesis is formulated; 4) the hypothesis is tested; and 5) a conclusion/s is arrived at, which help/s identify the patterns in the physical world.
Two Objectives of the Scientific Method
1) To uncover the laws governing the patterns in nature; and 2) To make life better and to solve problems
It is a planned inquiry to discover new facts, to confirm or deny the result of previous investigations by testing hypothesis/es.
Experimentation
It is that variable which is presumed to cause, effect, or stimulate the outcome.
Independent Variable
It refers to the outcome or response variable.
Dependent Variable
These, by themselves, produce changes which can be mistaken to be the effect of the independent variable being considered. These variables thus need to be controlled.
Extraneous Variable
This is the group experimented on.
Treatment Group
This is used to establish a baseline for result comparison.
Control Group
Two types of Control Group
Negative Control and Positive Control
This is the control group that is not exposed to any type of treatment at all.
Negative Control
This is the control group that is not exposed to the experimental treatment but is exposed to another treatment that is known to have the same effect.
Positive Control
When does a conclusion become a theory?
If the conclusion of the experiment confirms the hypothesis and remains the same after a series of experiments by various individuals over a period of years.
When does a theory become a law?
If it has been proven to be universally valid and to have such a high degree of probability.
This is constantly subjected to testing, modification, and refutation as new evidences and ideas emerge.
Theory
This is the basic unit of life.
The Cell
What is biological organization based on?
Hierarchy of Structural Levels
What are the seven attributes/qualities of life?
1) Organization; 2) Metabolism; 3) Homeostasis; 4) Reproduction; 5) Growth and Development; 6) Response to Stimuli; and 7) Evolution and Adaptation
The use of energy to perform the different activities of the body.
Metabolism
Energy Utilization
Anabolism
Energy Production
Catabolism
The “thermostat” of the body
Hypothalamus
This characteristic of biological processes means that an output or product of a process regulates that process.
Self-regulating
Slows or stops processes
Negative Feedback or Feedback Inhibition
Speeds up a process
Positive Feedback
Provides the blueprint for the organization, development, and function of living organisms
DNA
This produces more or larger cells.
Growth
This produces organisms with a defined set of characteristics for a particular organism; also includes differentiation.
Development
Responses of plants to their respective environments
Tropisms
Response of animals to their respective environments
Taxis
Short-term Responses
Adjustment/Irritability
Changes within a single lifetime
Short-term Responses
Changes that require multiple generations
Long-term Responses
This is the genetic change in a population through time
Evolution
This is the consequence of evolutionary change.
Adaptation
This is the change in an organism’s structure or habits to survive new environments.
Adaptation
What are the five characteristics of animals?
1) Multicellular, Ingestive Heterotrophs; 2) Lacks Cell Wall; 3) Stores Carbohydrates as Glycogen; 4) Exhibits Mobility and Complex Behvaior; 5) Presence of Hox Genes
What are the subdivisions of Gross Anatomy?
Comparative Anatomy and Human Anatomy
Study of inhertance of characteristics from parents to offspring; heredity and variation
Genetics
Study of the relationship/s of organisms to each other and to their respective environments
Ecology
Study of the distribution of animals throughout the world
Zoogeography
Study of the distribution of animals through time
Paleontology
An old science; Involves the identification and classification of organisms
Taxonomy
Study of the change in population through time
