• humans
  • Its presence and functionality in humans was controversial, though most studies agree the organ regresses during fetal development. (wikipedia.org)
  • Chemical communication does appear to occur among humans, but this does not necessarily imply that the human vomeronasal organ is functional. (wikipedia.org)
  • The vomeronasal organs (VNOs) of two humans, a male neonate and a female adult, were examined for immunolocalization of calbindin-D28k (calbindin) which has been immunolocalized to VNO receptor cells in other mammals. (semanticscholar.org)
  • Anatomical evidence for an endocrine activity of the vomeronasal organ in humans. (semanticscholar.org)
  • In the context of human evolution, human vestigiality involves those traits (such as organs or behaviors) occurring in humans that have lost all or most of their original function through evolution. (wikipedia.org)
  • In modern humans, the vermiform appendix is a vestige of a redundant organ that in ancestral species had digestive functions, much as it still does in extant species in which intestinal flora hydrolyze cellulose and similar indigestible plant materials. (wikipedia.org)
  • tissues
  • Some of these organs that had lost their obvious, original functions later turned out to have retained functions that had gone unrecognized before the discovery of hormones or many of the functions and tissues of the immune system. (wikipedia.org)
  • Cells, Tissues, Organs. (wikipedia.org)
  • vestigial
  • For the greater part Organs which may be rightly termed Vestigial. (wikipedia.org)
  • His list of supposedly vestigial organs included many of the examples on this page as well as others then mistakenly believed to be purely vestigial, such as the pineal gland, the thymus gland, and the pituitary gland. (wikipedia.org)
  • system
  • Its presence in many animals has been widely studied and the importance of the vomeronasal system to the role of reproduction and social behavior (through its influence on the anterior hypothalamus) has been shown in many studies. (wikipedia.org)
  • Structure and function of the vomeronasal system: an update. (semanticscholar.org)
  • The nervous system has a specific sensory nervous system, and a sense organ, or sensor, dedicated to each sense. (wikipedia.org)
  • Function
  • When the vomeronasal organ is removed or damaged during a maxillary osteotomy, the inhibitory function is lost, the patient loses the involuntary ability to exclude inappropriate mates, may become less committed to an existing mate, or even become promiscuous. (biomedcentral.com)
  • long
  • Conversely, the elephant's nose has elaborated into a long, muscular, manipulative organ called the trunk. (wikipedia.org)
