The relative locations of the supraorbital, infraorbital, and mental foramina: A cadaveric study.

J Anat 2021 Jun 12. Epub 2021 Jun 12.

Department of Cell Systems and Anatomy, UT Health San Antonio, San Antonio, Texas, USA.

The purpose of this study is to investigate the applicability of the current surgical guideline stating that the main facial foramina that transmit cutaneous nerves to the face (supraorbital notch/foramen, infraorbital foramen, and mental foramen) are equidistant from the midline in European and Hispanic populations. Previous studies suggest this surgical guideline is not applicable for all ethnicities; however, to our knowledge, no data have been published regarding the accuracy of this guideline pertaining to the Hispanic population. An experimental study was performed on 67 cadavers donated to the Human Anatomy Program at UT Health San Antonio. Read More

Altered Gene Regulatory Networks Are Associated With the Transition From C to Crassulacean Acid Metabolism in (Oncidiinae: Orchidaceae).

Front Plant Sci 2018 28;9:2000. Epub 2019 Jan 28.

Department of Plant Biology, University of Georgia, Athens, GA, United States.

Crassulacean acid metabolism (CAM) photosynthesis is a modification of the core C photosynthetic pathway that improves the ability of plants to assimilate carbon in water-limited environments. CAM plants fix CO mostly at night, when transpiration rates are low. All of the CAM pathway genes exist in ancestral C species, but the timing and magnitude of expression are greatly altered between C and CAM species. Read More

Cranial Pair 0: The Nervus Terminalis.

Anat Rec (Hoboken) 2019 03 17;302(3):394-404. Epub 2018 May 17.

Laboratorio de Neuroplasticidad y Neurodegeneración, Facultad de Medicina de Ciudad Real, Centro Regional de Investigaciones Biomédicas, Universidad de Castilla-La Mancha, Ciudad Real 13071, Spain.

Originally discovered in elasmobranchs by Fritsh in 1878, the nervus terminalis has been found in virtually all species, including humans. After more than one-century debate on its nomenclature, it is nowadays recognized as cranial pair zero. The nerve mostly originates in the olfactory placode, although neural crest contribution has been also proposed. Read More
