QUESTIONS WITH SOLUTIONS
GRADED A+
◍ Dentinogenesis.
Answer: Proces of dentin formation
◍ MALT- GALT- stomach.
Answer: 191 What is this image as a whole?
◍ Interradicular (alveolodental ligament).
Answer: found only between roots of multirooted teeth- from cementum to
cementum only, no bony attachment- resist intrusive, extrusive, tilting,
rotational forces
◍ How do we perceive taste?.
Answer: Taste cells are associated w sensory neuron processes which
receive messages of taste sensation through receptorsMessage is sent to
CNS to be identified as certain type of taste
◍ What is pulpal mode of entry?.
Answer: Apex. Accessory canals.
◍ Where is the tomes granular layer found?.
Answer: Found in the root area of tooth just below cementum
◍ What is the function of hemopoetic tissue?.
Answer: Transports white blood cells to connective tissues
◍ microtubules.
Answer: long slender tubes w diameters 2 or 3x greater than microfilaments-
, usually stiff, forming an internal skeleton within a cell which helps
MAINTAIN the SHAPE of the cell- provides strength to the structure of:
cilia (shorter, many), flagella (longer, few), centrioles, mitosis spindle
◍ Lymph.
Answer: Tissue fluid that drains from surrounding region into lymphatic
vessels- increased pressure within interstitial spaces forces some fluid into
the lymphatic capillaries- transports foreign particles to the lymph nodes and
returns protein into the bloodstream
◍ stomach.
Answer: 211
◍ Paracortex.
Answer: 133
◍ columnar.
Answer: rectangular
◍ nerve supply.
Answer: Cell bodies of afferent axons lie in the dentinal tubules. Changes in
temperature, vibrations, and chemical changes are perceived only as PAIN.
◍ What are sharpey fibers?.
Answer: Serve to anchor periosteum firmly to bone
◍ Combination of serous and mucous cells called.
Answer: serous demilunes
◍ Spleen.
Answer: 161 What is this image as a whole?
◍ Hyperkeratinization + examples.
Answer: non KT tissue can become KT, response to frictional or chemical
traumaex. Linea alba, frictional keratosis, gingival fibrosis, nicotine
stomatitis
◍ How do epiblast and hypoblast layers become mesoderm and endoderm?.
Answer: Migratory cells move to the middle between epiblast and hypoblast
, layers - becomining mesoderm and endoderm
◍ Hunter-Shreger Bands.
Answer: change the direction of rods from one prism to the next. Originate
from DEJ and run perpendicular to lines of retzius. Altering zones have
different mineral content, which allows for adaption of occlusal forces.
◍ Duodenum (small intestine).
Answer: 269 what is this image as a whole?
◍ Lobule.
Answer: 320 What is the line?
◍ 4 life cycles of a cell and their basic description.
Answer: Interphase - DNA ReplicationMitosis - Cell DivisionCytokinesis
(cytoplasmic Division)Differentiation
◍ Adipocyte.
Answer: 24
◍ Locations of Simple Columnar Epithelium (Ciliated and Non-Ciliated).
Answer: Non Ciliated:Stomach, large/small intestine, cervical
canalCiliated:uterus, fallopian tubes, small intra pulmonary bronchi (lungs),
male reproductive (ductus de Ferens)
◍ acini.
Answer: group of cells, like cluster of grapes- each acinus is located at the
terminal part of the gland connected to the ductal system, with many acini
within each lobule of the gland
◍ Palatine Tonsil.
Answer: 188 What is this image as a whole?
◍ Where are tight junctions located?.
Answer: cells that line the inside of the small intestine
◍ Lymphatic Nodule with Germinal Center.
Answer: 112
