Insect Physiology - Nervous System

Nervous System

Insects have a complex nervous system which incorporates a variety of internal physiological information as well as external sensory information (Gullan & Cranston, 2005) Like invertebrates the basic component is the neuron or nerve cell. This is made up of a dendrite with two projections that receive stimuli and an axon, which transmits information to another neuron or organ, like a muscle. As for vertebrates, chemicals (neurotransmitters such as acetylcholine and dopamine) are released at synapses (Gullan & Cranston, 2005).

Famous quotes containing the words nervous system, system and/or nervous:

    A car can massage organs which no masseur can reach. It is the one remedy for the disorders of the great sympathetic nervous system.
    Jean Cocteau (1889–1963)

    In the course of the actual attainment of selfish ends—an attainment conditioned in this way by universality—there is formed a system of complete interdependence, wherein the livelihood, happiness, and legal status of one man is interwoven with the livelihood, happiness, and rights of all. On this system, individual happiness, etc. depend, and only in this connected system are they actualized and secured.
    Georg Wilhelm Friedrich Hegel (1770–1831)

    A car can massage organs which no masseur can reach. It is the one remedy for the disorders of the great sympathetic nervous system.
    Jean Cocteau (1889–1963)
