Supraesophageal ganglion (5), Subesophageal ganglion (31) The subesophageal ganglion continues the nervous system and lies ventral to the esophagus. Finally, the segmental ganglia of the ventral nerve cord are found in each body segment as a fused ganglion; they provide the segments with some autonomous control.
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.
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.
The function of taste perception is vital to help prevent harmful or rotten foods from being consumed. There are also taste buds on the epiglottis and upper part of the esophagus . The taste buds are innervated by a branch of the facial nerve the chorda tympani , and the glossopharyngeal nerve .

A typical insect head possesses a pair of antennae; eyes; mandibles, labrum, maxillae and labium (the latter four forming the cluster of "mouth parts", no. 32. in the diagram). Lying above the oesophagus is the brain or supraesophageal ganglion , divided into three pairs of ganglia: the protocerebrum, deutocerebrum and tritocerebrum from front ...
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 ...
Retinal ganglion cell (RGC) found in the ganglion cell layer of the retina [1] Cells that reside in the adrenal medulla, where they are involved in the sympathetic nervous system's release of epinephrine and norepinephrine into the blood stream; Cells of the sympathetic ganglia; Cells of the parasympathetic ganglia; Cells of the spiral ganglia [2]
