CORRECT ANSWERS GRADED A+
◍ Cardiac tissue.
Answer: Found only in heartCells are joined by intercalated discsCells are
arranged in branched, interconnected networksStriated, involuntary muscle
◍ Abraction.
Answer: LOSS of tooth structure (Wedge-shaped lesions) at the CERVICAL
NECK AREA. Of teeth from transmission of forces during occlusion and
mastication. Caused by compressive and tensile forces during tooth flexure
◍ Capillary.
Answer: 62
◍ Tunica Media.
Answer: 34 What is within this band?
◍ Proliferation.
Answer: Controlled cellular growth and accumulation of byproducts
(interstitial growth/ appositional)
◍ What are the causes of hypercementosis?.
Answer: 1. Chronic periapical inflammation2. Occlusal trauma3.
Compensatory mechanism in response to attrition to increase occlusal tooth
height
◍ epithelium.
Answer: 195
◍ What are hemidesmosomes?.
Answer: Attachment of cell to an adjacent non-cellular surface (cell to
, basement) Allows gingival tissue to adhere to tooth surface by epithelial
attachment
◍ esophagus.
Answer: 201 what is the image as a whole?
◍ Golgi Apparatus.
Answer: "chemical process and packaging center"Second largest organelle,
stack of flat membranous sacs (pancakes)Sorts, condenses, packages, and
delivers proteins from Rough ER. Processes protein from Ribosomes.
Attached to cell membrane and releases by exocytosis.
◍ Media.
Answer: 46
◍ What is the turnover time?.
Answer: Time it takes for the newly divided cells to be completely replaced
throughout tissueSkin: 27 daysOral cavity: 14 days
◍ Trabeculae.
Answer: 171
◍ Von ebner gland.
Answer: Watery secretion that washes tongue so new taste can be perceived
◍ Muscular Artery.
Answer: 44 What is this image as a whole?
◍ What are microtubules?.
Answer: Long slender tubes; maintain shape of cell; provides strength to
structure of:Cilia, flagella, centroles, miotic spindle
◍ fordyce granules.
Answer: ectopic (misplaced) sebaceous glands- 60-70% adults have them-
variation of normal
◍ Endothelium of Intima.
Answer: 86
, ◍ periosteum.
Answer: double layered, dense ct sheath- outer layer contains blood vessels
and nerves - inner layer contains single layer of osteoblasts (bone growth)
◍ What is the haversian canal?.
Answer: Central vacular canal; runs longitudinally; provides nutrition for
bone
◍ 3 layers of basement membrane.
Answer: 1. lamina lucida (clear, basal lamina)2. lamina densa (dense, basal
lamina)3. reticular lamina (contains collagen and reticular fibres)
◍ pseudostratified columnar epithelium.
Answer: CROWDED COLUMNAR cells (rectangular form is destroyed) -
NUCLEI are at DIFF levels- MOISTENS, WARM & CLEAN lining
membranes-CILIATED/NONciliated- location: UPPER RESPIRATOY
TRACT (+nasal & paranasal cavity)
◍ Adventitia.
Answer: 92
◍ Fenestrations.
Answer: 71
◍ Cementocytes.
Answer: Cementoblasts that become trapped in the cementum
◍ nucleolus.
Answer: produces RNA and nucleotides of 2 other types of RNA
◍ goblet cells.
Answer: secret MUCIN to moisten and humidify the nasal cavity and trap
foreign materials
◍ Axon.
Answer: Impulses AWAY from cell body
◍ What are osteoclasts?.
Answer: Bone-resorbing cell
