  2. Insect physiology - Wikipedia

    en.wikipedia.org/wiki/Insect_physiology

    The salivary glands (30) produce saliva; the salivary ducts lead from the glands to the reservoirs and then forward through the head to an opening called the salivarium behind the hypopharynx; which movements of the mouthparts help mix saliva with food in the buccal cavity. Saliva mixes with food, which travels through salivary tubes into the ...

  3. Insect mouthparts - Wikipedia

    en.wikipedia.org/wiki/Insect_mouthparts

    The hypopharynx is a somewhat globular structure, located medially to the mandibles and the maxillae. In many species it is membranous and associated with salivary glands. It assists in swallowing the food. The hypopharynx divides the oral cavity into two parts: the cibarium or dorsal food pouch and ventral salivarium into which the salivary ...

  4. Polytene chromosome - Wikipedia

    en.wikipedia.org/wiki/Polytene_chromosome

    In insects, polytene chromosomes are commonly found in the salivary glands; they are also referred to as "salivary gland chromosomes". The large size of the chromosome is due to the presence of many longitudinal strands called chromonemata; hence the name polytene (many stranded). They are about 0.5 mm in length and 20 μm in diameter.

    There can hardly be any doubt (although it has not been proven) that ectohormones of the salivary gland secretions play the main role in this redifferentiation." – Albrecht Bethe[6] Bethe further divided the ectohormones into homoiohormones, which – according to today's definition of a pheromone – act on individuals of the same species ...

  8. Insect morphology - Wikipedia

    en.wikipedia.org/wiki/Insect_morphology

    The salivary glands (element 30 in numbered diagram) in an insect's mouth produce saliva. The salivary ducts lead from the glands to the reservoirs and then forward through the head to an opening called the salivarium, located behind the hypopharynx. By moving its mouthparts (element 32 in numbered diagram) the insect can mix its food with saliva.

  9. Salivary gland - Wikipedia

    en.wikipedia.org/wiki/Salivary_gland

    The two parotid glands are major salivary glands wrapped around the mandibular ramus in humans. [6] These are largest of the salivary glands, secreting saliva to facilitate mastication and swallowing, and amylase to begin the digestion of starches. [7] It is the serous type of gland which secretes alpha-amylase (also known as ptyalin). [8]
