Bio 201 Exam 1
What is gross anatomy - answer...branch of anatomy that deals with the structure of
organs and tissues that are visible to the naked eye.
Define embryology, cytology & microscopic anatomy - answer...Embryology-
development before birth, Cytology- cells of the body, Microscopic Anatomy- structures
to small to be seen with naked eye
The main component of the cytoplasm - answer...Cytosol
What is mitosis - answer...cell division that results in two daughter cells each having the
same # and kind of chromosomes as the parent nucleus, typical of ordinary tissue
growth.
Role of leptin in the body - answer...Leptin regulates energy intake and fat stores so that
weight is maintained within a relatively narrow range. "Leptin is a hormone made by fat
cells, that decrease appetite"
What is an organic molecule - answer...are the molecules of life and are built around
chains of carbon atoms that are often quite long.
Some functions of lysosomes - answer...they breakdown, degrade and digest safely
within a cell
What type of epithelium would you find dense microvilli( lining intestines and kidney
tubules) - answer... simple cubodoidal epithelium
Where would you find Pseudostratified columnar epithelia - answer...ciliated is found in
the trachea and upper respitory tract; non ciliated is found in the male sperm
Major functions of fat - answer...provides reserve fuel for cell, insulates against heat
loss, supports and protects organs
What is metabolism - answer... either Anabolism- which build larger molucules from
smaller ones ( storage of energy). Catabolism- which breaks down from complex
molecules to simpler ones ( with the release of energy).
What do collagen fibers do for IVDs ( intervertebral discs) - answer...they provide
strentgh with there crosslinks which resits being pulled apart, as well as cushoining.
What produces the most ATPs during cellular respiration - answer...glucose, and the
electron transport chain
, What is a frontal section/cut - answer...through torso- divides the body by anterior(front)
and posterior(back)
Improperly digesting nutrients, may indicate a problem of which tissue layer -
answer...simple epithelium
When does the body normally use proteins for energy (ATP) - answer...When the body
is in starvation mode( doesnt have enough carbohydrate or fat calories for Atp
production.
Normal constituents of the plasma membrane - answer...seperates the inracellular fluid
wihin the cell and the extracellular fluid outside the cell.
What are endocrine glands - answerductless glands - secrete hormones directly into
blood or lymph ex. pituitary, thyroid
What is phagocytosis - answer...cell eat- ingestion of bacteria or other material
The primary function of cellular respiration - answer...metabolism to form ATP
The basic structural material of the body is made of what - answer...Proteins
What are microvilli - answer...projections from the surface of some cells, have a fuzzy
appreance called a brush border (fingerlike extensions)
What is passive membrane transport; - answer...substances cross the membrane
without any energy input from the cell; unlike active transport that requires energy from
the cell
What are the characteristics of Psuedostratified Columnar Epithelium - answer...single
layer of cells of differing heights, some not reaching the free surface; nuclei seen at
diffrent levels; may contain mucus secreating cells and bear cilia.
What is basal metabolic rate (BMR) - answer...reflects the energy the body needs to
perform only its most essential activities. ( this happens at an in rest state ; neutral)
What is Simple Squamous Epithelial tissue - answer...one layer, flat egg shaped ,
allows materials to pass by diffusion and filteration in sites where protection is not
important; secretes lubricating substances in serosae;
Why should elderly patients decrease their caloric intake - answer...becasue their BMR
reduces dramaticly, if they increse their calorie intake they will gain weight
The functions of tRNA - answer...carry amino acids to the ribosomes, there they decode
mRNA's msg for amino acid sequence in the polypeptide to be built
