mechanical transmission of the pathogen
Term
Germ theory is the idea that _______. Germ theory was proposed by_______.
Definition
"germs" or pathogens are the cause of the disease; Marcello Malpighi
Term
Some disease pathogens can be moved through generations of the vector by passing from the mother to her young (in the egg). This is referred to as
Definition
Vertical transmission
Term
When the first "explorers" traveled to parts of the world that they had not previously visited there are often severe medical consequences. The primary reason is because
Definition
All the Above:
-the explorers brought arthropods with them that were new to the region of the world being explored
-brought diseases with them to which the native populations had no natural immunity
-brought diseases with them to which the native populations had no acquired immunity
Term

Term
1. What does CDC stand for?
Definition
CDC stands for Centers for Disease Control.
Term
2. What are the requirements that organisms need to meet to place them in the same species?
Definition

Term
4. How many sections are the segments of an insect divided into? Remember your grasshopper illustration and be able to label the parts that we discussed when we did the grasshopper class.
Definition
There are eleven sections of an insect that are divided into three main parts; the head, the thorax, and the abdomen.
Term
Myiasis
Definition
is the invasion of living host tissue. It is the invasion of living flesh by bott flies, and fly maggots.
Term
Dermatosis:
Definition
irritation of the skin through toxins or hairs—spread from Beatles, caterpillars, or tarantulas: their hair is toxic and can rub your skin wrong.
Term
Envenomization:
Definition
injection of venom when an arthropod stings or bites (spiders, wasps, ants, bees, scorpions). Production of toxins when touched or ingested (blister Beatles and certain caterpillars)→antigenic compounds in saliva.
Term
Ovipositor
Definition
the egg laying device on insects

-Population control
-scavenger/decomposer
Term
Ways arthropods are detrimental to humans
Definition
destroy plants, announce/psychosis, vector plant diseases, bite/feed on tissue
Term
Epidemiology
Definition
The study of the distribution and determinance of disease prevalence in population of organisms

Symptomatic
Definition
shows signs of the disease
Term
Asymptomatic
Definition
little or no response to disease
Term
Protozoa
Definition
SIngle celled organisms, vertebras do not usually require strong immunity to protozoas
Term
Helminthes worms:
Definition
immunity responses in human weak. Tapeworms, flukes, round worms, spiny-headed worms. Filarial worms.
