Mouth development
A mouth is present in all animals, and comprises an opening from the outside into the oral cavity and the beginnings of the digestive tract to allow eating. This review focuses on the earliest steps in mouth formation. In the first half, we conclude that the mouth arose once during evolution. In all animals, the mouth forms from ectoderm and endoderm. A direct association of oral ectoderm and d...
متن کاملMaking a mouth: elucidating morphogenetic events of mouth development in the sea urchin Lytechinus variegatus
Deuterostomes are bilaterian animals in which the blastopore, the site of gastrulation, becomes the anus and the mouth develops secondarily. Deuterostome phyla include Chordata, such as vertebrates like ourselves, and Echinodermata, such as sea urchins. The extent of homology among deuterostome mouths is unknown. To address this question, this thesis compares three aspects of mouth morphogenesi...
متن کاملMouth breathing in allergic children: its relationship to dentofacial development.
While there are many claims that abnormal breathing patterns alter facial growth, there are limited controlled data to confirm this. We evaluated forty-five North American Caucasians of both sexes, ranging in age from 6 to 12 years. Thirty chronically allergic mouth-breathing subjects were selected from a pediatric allergy practice, and fifteen nonallergic nose breathers were selected from a ge...
متن کاملDevelopment of prenatal lateralization: evidence from fetal mouth movements.
BACKGROUND Human lateralized behaviors relate to the asymmetric development of the brain. Research of the prenatal origins of laterality is equivocal with some studies suggesting that fetuses exhibit lateralized behavior and other not finding such laterality. Given that by around 22weeks of gestation the left cerebral hemisphere compared to the right is significantly larger in both male and fem...
متن کاملDevelopment of Chlorhexidine Thermosensitive Gels as a Mouth Antiseptic
Chlorhexidine is a widely used antiseptic with a broad spectrum of antimicrobial activities. The aim of this research is to develop a chlorhexidine thermosensitive gel as a mouth antiseptic by using lutrol F127 as a gelling agent. Due to its thermosensitive properties, lutrol has a sol-gel transition ability to change from solution stage at low temperature to the viscous gel at high temperature...
