Biology 255 Final Exam Questions With
Verified Solutions
The ability of a specific tissue or organ to respond to the presence of a hormone is dependent on
the presence of the appropriate receptors on or in the target tissue or organ cells.
.
Which pancreatic cells make somatostatin, which inhibits release of both insulin and glucagon?
Delta Cells
Insulin, a small (51-amino-acid) protein, is synthesized by the beta cells of the pancreas. This hormone
is released
when the body's glucose levels rise.
Which hormone does the placenta make? (It is used to detect pregnancy.)
Chorionic gonadotropin
The hormone made by the pineal gland is
melatonin.
Mineralocorticoid is to aldosterone as glucocorticoid is to
Cortisol
The adrenal medulla is derived from
Ectoderm (Nervous Tissue)
When we ingest large molecules such as lipids, carbohydrates, and proteins, they must be broken into
smaller molecules. This series of reactions is called
Digestion
Important peritoneal folds do NOT include the
Round ligament
Which of these is NOT part of the splanchnic circulation?
Splanchnic Circulation = Liver and Spleen; hepatic, splenic, left gastric, messentric, intestines.
The layer of the digestive tube containing blood vessels, lymphatic nodes, and a rich supply of elastic
fibers is the
Submucosa
Which is the projection of the soft palate, helping to close off the nasopharynx while you swallow?
uvula
Tooth Structure incudes
a thin periodontal ligament holding the tooth in its place
, Which of the following tongue papillae contain taste buds?
fungiform and circumvallate
Which of the following tongue papillae types has no tastes buds, but functions to give teh tough
roughness and provide friction?
filiform
the primary function of the gastroesophageal aka lower esophageal or cardiac sphincter is to
prevent reflux of food and acid from the stomach
which of the following stomach cells produce intrinsic factor?
parietal cells
the structures of small intestine cells providing microscopic finger like projections in the lumen to the
small intestine to provide increased for food molecules absorption called
microvilli
the functions of the gallbladder include
storage and concentration of bile
which is the exocrine product of the pancreas?
enzyme-rich juice for digestion
which is the correct order of small intestine segments as encountered by chyme?
duodenum, jejunum, ileum
which of these are pocketlike sacs along the large intestine?
haustra
which is NOT a beneficial function of the normal bacterial flora of the colon
Normal flora functions: colonize colon, ferment carbs--> release flatus, synthesize B and K vitamins
anus develops from
mesoderm
the _____ artery lies on the boundary between the cortex and medulla of the kidney
arcuate
.
which type of nephron has a short loop of henle and produces dilute urine
Cortical nephrons
