  2. Supraesophageal ganglion - Wikipedia

    en.wikipedia.org/wiki/Supraesophageal_ganglion

    The supraesophageal ganglion (also "supraoesophageal ganglion", "arthropod brain" or "microbrain" [1]) is the first part of the arthropod, especially insect, central nervous system. It receives and processes information from the first, second, and third metameres .

  3. Pain in crustaceans - Wikipedia

    en.wikipedia.org/wiki/Pain_in_crustaceans

    Each ganglion receives sensory and movement information via nerves coming from the muscles, body wall, and appendages such as walking legs, swimmerets and mouthparts. The ganglia show great functional autonomy; information received by the ganglion is processed by the same ganglion, enabling a faster response than if the message had to travel ...

  4. Arthropod head problem - Wikipedia

    en.wikipedia.org/wiki/Arthropod_head_problem

    Lying above the oesophagus is the brain or supraesophageal ganglion, divided into three pairs of ganglia: the protocerebrum, deutocerebrum and tritocerebrum from front to back (collectively no. 5 in the diagram).

  5. Nervous system - Wikipedia

    en.wikipedia.org/wiki/Nervous_system

    Typically, each body segment has one ganglion on each side, though some ganglia are fused to form the brain and other large ganglia. The head segment contains the brain, also known as the supraesophageal ganglion. In the insect nervous system, the brain is anatomically divided into the protocerebrum, deutocerebrum, and tritocerebrum.

  7. Suboesophageal ganglion - Wikipedia

    en.wikipedia.org/wiki/Suboesophageal_ganglion

    Neurons in the suboesophageal ganglion control movement of the head and neck as well. [1] Supraesophageal ganglion(5), Subesophageal ganglion(31) It is composed of three pairs of fused ganglia, each of which is associated with a pair of mouthparts. Therefore, the fused parts are called the mandibular, maxillary and labial ganglia.

  8. Ventral nerve cord - Wikipedia

    en.wikipedia.org/wiki/Ventral_nerve_cord

    Like the vertebrate spinal cord, the function of the ventral nerve cord is to integrate and transmit nerve signals. It contains ascending and descending neurons that relay information to and from the brain, motor neurons that project into the body and synapse onto muscles, axons from sensory neurons that receive information from the body and environment, and interneurons that coordinate ...
