Answer:An indurated wheal over 10 mm in diameter appears in 48 to 72 hours.
Explanation:Tobacullosis is a very deadly Microbiological infection specifically caused by Mycobacterium tuberculosis,it is very contagious and can easily spread from one patient to another uninfected person.
PPD(purified protein derivative) is a test procedure which involves the use of the skin to test for the presence of Mycobacterium tuberculosis which is the cause of Tuberculosis.
If an indurated wheal over 10 mm in diameter appears in 48 to 72 hours occurs it means a positive test result.
Answer and Explanation:
1) Second line of Defense ---------> includes cells and processes that help remove or neutralize organisms that have penetrated mechanical barriers.
Second line of Defense uses cells such as phagocytic leukocytes and antimicrobial proteins or uses a procedures like inflammatory responses and fever in order to combat with the pathogens which crosses the first line of Defense
2) First line of Defense ---------> includes mechanical barriers that prevent microorganisms from entering the body.
Skin mucous membranes and other secretions of the skin works as the first line of Defense which provides a barrier that prevents the entry of pathogens into the body in first place.
3) Third line of Defense ---------> is a complex defense system that recognizes and reacts to specific organism.
If pathogens somehow manage to cross the first and second line of Defense, it's then encounter by the third line of Defense which is a specialized systems used to kill these pathogens altogether. This includes Lymphocytes, antibodies and memory cells which helps in permanently killing the foreign pathogen.
True.
A neuron is nerve cell. It is considered the functional unit of the nervous system and it carries electrical impulses to the appropriate part of the nervous system or interprets the impulse and allows a response.
The electrical impulse or message is carried through the fibrous extensions of the neuron called dendrites to the cell body. It passes through the cell body via the axon and finally to the end brush , a collection of fibers that extend off the axon.
The electrical impulse then triggers a release of chemicals which permit the impulse to jump through the synapse, the space between the axon of one neuron and the dendrites of the next neuron.
