tekilochka [14]

Vectorborne transmission of an infectious organism occurs via <u>animals or insects. </u>

Vectors are living organisms that can transfer an infectious disease from infected animals to humans. These species are known as arthropods. It includes mosquitoes, ticks, triatomine bugs, sandflies, etc.

There are two types of vectors; Biological and mechanical.

Biological vectors such as mosquitos transmit the disease by biting the host body. Mechanical vectors on the other hand cause infectious disease just by physical contact.

Arthropod vectors are cold-blooded. The diseases that are transmitted by them are known as vector-borne diseases. Malaria and Dengue are examples of vector-borne diseases.

Acetycoline is an example of neurotransmitter and it is located in the parasympathetic nervous system. Ligand are substance that form complexes with biomolecule. They serve biological purpose with this biomolecule.

This ligand binds to target site. Neurotransmitter act as ligand by binding to receptor in the postsynaptic neuron and acetycoline a type of neurotransmitter can also serve as ligand they bind to acetycoline receptor on cell surface.
