What is the “cribriform plate”?
  1. ক

  2. খ
    খ) The structure that separates the nose from the nasopharynx.
  3. গ
    গ) Part of the ethmoid bone through which olfactory nerves pass.
  4. ঘ
    ঘ) The nose structure through which air is warmed and humidifi ed as it passes.
ব্যাখ্যা
The cribriform plate of the ethmoid bone has many foramina through which pass olfactory nerves that transmit sensory information from inhaled air to the olfactory bulbs.
১২.
Most abundant constituent of bone matrix
  1. ক
    ক) Bicarbonate
  2. খ
    খ) Citrate
  3. গ
    গ) Magnesium
  4. ঘ
    ঘ) Calcium hydroxyapatite
ব্যাখ্যা
About 50% of the dry weight of bone matrix is inorganic materials. Calcium hydroxyapatite is most abundant, but bicarbonate, citrate, magnesium, potassium, and sodium ions are also found. Significant quantities of noncrystalline calcium phosphate are also present. The surface of hydroxyapatite crystals is hydrated, facilitating the exchange of ions between the mineral and body fluids.
