Lesson 1

Zoology - branch of biology that deals with the life of animals.

1. Morphology - studies forms and structure of animals.
a. Gross anatomy - performs surgical technique ; dissection (cutting up).
b. Paleontology - studies pre-historic forms of animals through fossil. 2. Histology - study of tissues & organs, their structure, functions & composition at a microscopic level. 3. Cytology - study of the structure & function and its parts at microsopic level or electromicrospic level. 4. Physiology - study of living organism's function as a whole ; studies function of the vitak processes of living animals. 5. Embryology - study of formation & development of an animal until it is fully grown. 6. Genetics - deals with mode of trandmission of traits from one generation to the next ; studies heredity, and variations in similar related animals. 7. Evolution - any change across successive generations in the inherited characteristics of biological populations. 8. Ecology - study of relation of the animals to their immediate environment.

a. Biotic - plantd, other animals, microorganism: bacteria, viruses, protozoa, fungi.
b. Abiotic - air, water, land/soil, and rocks.
9. Zoogeography - distribution of animals in space.
10. Taxonomy -classification, study of laws and principle governing the grouping and naming of animals. 11. Parasitology -study of parasites (organism that live on the expense of another organism). 12. Molecular Biology - molecular and subcellular structure the chemical reaction underlying biological processes.

* paternity testing - DNA testing in medical legal cases.

Invertebral zoology - without back-bone.
a. Protozoology - unicellular animal
b. Helmintology - helminths/ parasitic worms
c. Malcology - mollusks
d. Entomology - insects
Vertebral Zoology - with back-bone.
a. Ichthyology - fish
b. Herpetology - reptiles & amphibians
