Measurements were conducted in vivo in 37 volunteers with healthy finger and toe nails, using a skin pH meter. The pH of unwashed and washed fingernails and the big toenails was measured and the influence of washing, anatomical site (fingers/toes), side (left/right), finger digit (digits 1-5) and gender were determined. The pH of the nail plate surface was around 5. There was no significant difference between the sides i.e. right or left hand/foot, among the ten fingernails, and between the two great toenails. However, toenails had a significantly higher pH than fingernails. Washing the nails caused an immediate, but transient increase in pH, which was not sustained with time, and pH returned to pre- washing levels within 20 minutes. In males, washing did not significantly influence finger or toe nailplate pH. In females however, washed fingernails had a significantly higher pH than unwashed ones, while there was no difference in the pH of the toenails. The pH of the nail plate interior, measured after tape-stripping, was found to be slightly lower than that at its surface.

  • Cheek & Tongue Pressures
    European Journal of Orthodontics 21 (1999) 299–309 1999 European Orthodontic Society Cheek and tongue pressures in the molar areas and the atmospheric pressure in the palatal vault in young adults Urs Thüer, Robert Sieber and Bengt Ingervall Department of Orthodontics, University of Bern, Switzerland SUMMARY The pressures acting on the maxillary and mandibular posterior teeth from the tongue and cheeks were measured in 24 adults aged 22–29 years. In addition, the pressure in the palatal vault was recorded. The pressure at two maxillary (buccal and lingual) and two mandibular (buccal and lingual) measuring points, and in the palatal vault was recorded simultaneously. Repeated recordings of the pressures at rest, and during chewing and swallowing were made. The pressures at rest were of similar magnitude (about 2 g/cm2) at the buccal and lingual sides of the mandibular posterior teeth. The median resting pressure at the maxillary posterior teeth was 2.7 g/cm2 on the buccal side and 1.0 g/cm2 on the lingual side. The difference in the maxilla was significant, but not in the mandible. It was concluded that the equilibrium of tooth position is maintained by the pressure from the cheeks and the tongue. During chewing and swallowing the pressures on the lingual side of the teeth were greater than those on the buccal side. At rest about half of the subjects had a negative pressure at the palatal vault, but no correlations between the resting pressure at the palatal vault and the resting pressures on the teeth were found.

Be sure to identify the major organs as you explore the extent of each system. As you encounter each structure, discuss its function and interactions with surrounding structures with your lab partners Recommendations: • Carefully follow the directions • Read the description of each incision and understand it prior to beginning • Each group should have a directions reader and a dissector • The rest of the group should follow along referring to the textbook or lecture notes with details on the structures being studied • Use the scissors for most incisions • All students handling the specimen must wear gloves Use the scalpel only when absolutely necessary Clean-up at the end of each dissection: • Dispose of lab discards in the provided receptacles • Place your pig into the plastic bag provided o Expel excess air from the bag and tie it shut o Write your group name and class time on the tag provided and attach it to the bag o Place the bags in the storage bin for your class • Return dissection instruments to their proper places in the set-up tray • Clean table tops with red bottled sanitizer • Wash hands before leaving class 1 FETAL PIG LAB ONE: Respiratory 1, Mouth, Pharynx & Thorax External Anatomy • Examine the fetal pig and locate the external features shown above. • Two rows of nipples of mammary glands are present on the ventral abdominal surface of both males and females.
