QUESTIONS WITH ANSWERS GRADED

◍ Crypt.
Answer: 190
◍ Nerve.
Answer: Neural processes in the peripheral nervous system (PNS)
◍ What are red blood cells?.
Answer: Biconcave disc; no nucleus; 1/3 is hemoglobinTransport oxygen
and carbon dioxide
◍ mesoderm.
Answer: urinary tract
◍ Dentinal hypersensitivity.
Answer: Dentinal tubules may become open due to caries, recession,
attrition, cavity preparation
◍ Where is enamel matrix derived from?.
Answer: Enamel matrix is ectodermal and is derived from inner enamel
epithelium (IEE) of enamel organ
◍ function of taste buds?.
Answer: contain the taste receptor cells, which are also known as gustatory
cells. The taste receptors are located around the small structures known as
papillae found on the upper surface of the tongue, soft palate, upper
esophagus, the cheek and epiglottis
,◍ Thymus.
Answer: 147
◍ locations of reticular CT.
Answer: liver, spleen, lymph
◍ Primary embryonic layers or primary germ layers.
Answer: Ectoderm, mesoderm, endoderm
◍ 2 types of cells found in cartilage.
Answer: chondroblasts and chondrocytes
◍ Disse.
Answer: 350
◍ Hypocalcification.
Answer: Chaly areas due to incomplete or lack of maturation, deficiency of
mineral content (Ca), enamel did not form properly
◍ life cycle of a cell.
Answer: 1. interphase (dna replication)2. mitosis (cell division)3.
cytokinesis (cytoplasmic division)4. differentiation
◍ lips.
Answer: non-keratinized squamous epithelium (inner lips)- lamina propria
contains minor seromucous salivary glands - submucosa contains muscle
fibers of the orbicularis oris muscle- vermillion border is the junction
between the oral mucosa and the skin of the face- contains eleidin (clear,
semi fluid, intracellular protein) so the blood vessels of the papillary layer
transpire thru making the color of the lips pink/red
◍ What is immature bone (primary bone)?.
Answer: First bone produced by either intramembranous or endochondral
ossification; many cells present; indistict lamellae
◍ Basophil.
Answer: 10
◍ Portal triad.
, Answer: 343 what is the line?
◍ What is the cause of cementicles? Is it cellular/cellular?.
Answer: Unknown cause, and is acellular
◍ floor of the mouth.
Answer: non-keratinized, thin- lamina propria: extensive vascular supply,
broad CT papillae- submucosa includes: submandibular and sublingual
salivary glands, loosely attached to bone/muscles
◍ Lumen.
Answer: 356
◍ examples of apocrine gland.
Answer: mammary glands
◍ Serous secretion.
Answer: Clear, watery with proteinContain digestive enzyme amylase (carb
digest)
◍ Capsule.
Answer: Connective tissue that surrounds the thyroid
◍ Sublingual gland duct.
Answer: Bartholin's duct
◍ hepatic arteriole.
Answer: 346
◍ parotid salivary gland.
Answer: largest, encapsulated gland- behind mandibular ramus, anterior and
inferior to the ear, between the skin of the cheek and masseter muscle-
stensons duct- the duct system, within the gland consists of LONG
INTERCALATED ducts and SHORT STRIATED ducts with basal
striations- it contains only serous acini therefore the secretion is mainly
serous- 25% of saliva volume
◍ esophageal glands.
Answer: 205
