What is a gene
...a unit of heredity that is transfered from a parent to
offspring and is held to determine some characteristic of the
offspring.
What are positive feedback systems, give examples
.. It encourages a process or amplifies the action of a
system. This will continue until Negative Feedback takes
over. Ex. during labor a hormone called oxytocin is released
that intensifies and speeds up contractions. The incresse in
conractions casues more oxytocin to be release and the
cycle goes on until the baby comes. The birth ends the
release of oxytocin and positive feedback.
What is gross anatomy
...branch of anatomy that deals with the structure of organs
and tissues that are visible to the naked eye.
Define embryology, cytology & microscopic anatomy
,...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
...Cytosol
What is mitosis
...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
...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
...are the molecules of life and are built around chains of
carbon atoms that are often quite long.
, Some functions of lysosomes
...they breakdown, degrade and digest safely within a cell
What type of epithelium would you find dense microvilli(
lining intestines and kidney tubules)
... simple cubodoidal epithelium
Where would you find Pseudostratified columnar epithelia
...ciliated is found in the trachea and upper respitory tract;
non ciliated is found in the male sperm
Major functions of fat
...provides reserve fuel for cell, insulates against heat loss,
supports and protects organs
What is metabolism
... 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)
