,What is heart block? - CORRECT ANSWER - Impaired transmission of
impulses from atrium to ventricle resulting in slower heart rhythms, and
pacemaker would be implanted
The bones of the skull, veretbral column, and rib cage are part of the _______ -
CORRECT ANSWER - Axial skeleton
Name 2 of the 4 factors affecting the velocity of action potential conduction. -
CORRECT ANSWER - Axonal diameter, myelination, chemical factors
(alcohol and anesthetics), physical factors (pressure and temperature)
What two factors directly affect cardiac output?
(a) stroke volume and resistance
(b) stroke volume and heart rate
(c) heart rate and mean arterial pressure
(d) heart rate and total peripheral resistance - CORRECT ANSWER - b- stroke
volume and heart rate
In what phase of the mitosis is this cell? - CORRECT ANSWER - Metaphase
What division of the nervous system regulates skeletal muscles? - CORRECT
ANSWER - Somatic nervous system
A ____ consists of one motor neuron and all the muscle fibers it innervates -
CORRECT ANSWER - motor unit
,Explain the polar nature of water , that is, why is water polar? - CORRECT
ANSWER - The oxygen is more electronegative compared to hydrogen
resulting in the electrons spending more time around oxygen conferring a partial
negative charge on the oxygen and less time around hydrogen thus conferring a
partial positive charge on the hydrogen.
In what form and in what location(s) do humans store the majority of their
carbohydrates? - CORRECT ANSWER - Humans store their carbohydrates as
glycogen in the liver and in skeletal muscles.
How can the Na+/K+ pump relate to the process of secondary active transport? -
CORRECT ANSWER - The ATP-driven Na+/K+ pump stores energy by
creating a steep concentration gradient for Na+ entry unto the cell. As Na+
diffuses back across the membrane through a membrane co-transporter protein,
it drives glucose against its concentration gradient into the cell.
What type of chemical bond holds two water molecules together? - CORRECT
ANSWER - Hydrogen bonding
What two hormones control bone remodeling? - CORRECT ANSWER -
Parathyroid hormone and calcitonin
The Frank-Starling law of the heart indicates that the stretching of cardiac cells
lead to: - CORRECT ANSWER - Increased contractile force, which increases
stroke volume
Explain the negative feedback mechanism that occurs when blood calcium
levels become too low - CORRECT ANSWER - Parathyroid hormone is
released and it (1) increases osteoclast activity activity (2) increases calcium
absorption from food (requires vitamin D) , and (3) increases calcium
reabsorption at the kidneys. These three responses cause blood calcium levels to
return to normal.
, Phagocytosis and pinocytosis are both specific types of which vesicular
transport? - CORRECT ANSWER - Endocytosis
Depolarization opens more sodium channels, which leads to increased
depolarization, which increases sodium permeability . This is an example of
(a) negative feedback
(b) positive feedback
(c) homeostasis
(d) feed-forward control - CORRECT ANSWER - b - positive feedback
What type of gland is distributed over most of the skin, especially on palms of
the hands and soles of the feet, and secretes sweat onto the surface of the skin? -
CORRECT ANSWER - Eccrine gland which is a specific type of a
sudoriferous (i.e. sweat gland)
Draw a hypertonic solutio - CORRECT ANSWER -
During excitation-contraction coupling, ________
(a) the action potential propagates along the sacrolemma and down the t-tubules
(b) calcium binds to troponin
(c) the binding sites for myosin are exposed
(d) all the above - CORRECT ANSWER - d- all the above
What is cell apoptosis? - CORRECT ANSWER - Programmed cell death
What epithelial tissue type is found in the urinary bladder?
