BIO 202 EXAM 1 QUESTIONS
AND CORRECT ANSWERS
(VERIFIED ANSWERS) A GRADE
Adenohypophysis = _?_ - correct answer- Anterior
pituitary
ADH and oxytocin are produced in the _?_ and stored in the _?_
- correct answer- Produced in the hypothalamus and
stored in the neurohypophysis
ADH is also known as _?_ - correct answer-
Antidiuretic hormone
Adrenergic vs. muscarinic receptor in cardiac pacemaker tissue
- correct answer- Parasympathetic hits Muscarinic ACh
Muscarinic - slows heart down
Since adrenergic stimulation can increase the activity of these
channels, this is an explanation for why the risk of sudden death
in individuals with LQTS is increased during increased adrenergic
states (i.e., exercise, excitement)
,Anatomical and physiological relationship between the
hypothalamus and anterior pituitary. - correct answer-
The hypothalamus is just superior to the anterior pituitary
Hypothalamus makes the hormones and they are stored and
stimulated in the anterior pituitary.
ANP and BNP - correct answer- Atrial natriuretic
peptide (ANP)
Produced by cells in right atrium
Brain natriuretic peptide (BNP)
Produced by ventricular muscle cells
The wall of the atrium releases ANP and the ventricle releses
BNP - these two go to the kidneys - tell them to get rid of the
sodium (and therefore water) - should decrease his blood
pressure
Antigens vs antibodies - correct answer- Antigens
- unique molecules on cell surface
- used to distinguish self from foreign
- foreign antigens generate immune response
Antibodies
- secreted by plasma cells
,- as part of immune response to foreign matter
Arteries vs. veins - anatomical and physiological differences -
correct answer- Arteries - strong and thick
Veins - smushed, valves
Baroreceptros - correct answer- Changes in BP
detected by stretch receptors (baroreceptors), in large arteries
above heart
Aortic arch
Carotid sinus (base of each internal carotid artery)
Be familiar with the general values found in a CBC, especially,
hematocrit, hemoglobin, and WBC count. - correct
answer- Complete blood count
A LOT MORE RBC (millions) than WBC (thousands)
Platelets (hundred thousands)
Hematocrit - around 35-55%
Hemoglobin - around 12-18
Briefly, list AND describe the endocrine tissues of other systems.
Yes, we will cover these in detail as the semester progresses, but
, you still need to be familiar with them for this unit! - correct
answer- Many organs of other body systems have
secondary endocrine functions
Intestines (digestive system)
Kidneys (urinary system)
Heart (cardiovascular system)
Thymus (lymphoid system and immunity)
Gonads (reproductive system)
Breast Tissue (reproductive system)
Can preload be increased indefinitely? Why or why not? -
correct answer- It can be strengthened, but it can also
get overstretched if too much blood is going in, but efficiency
goes down with stretching
Cardiac muscle vs. skeletal muscle action potential - correct
answer-
Clotting cascade and the formation of fibrin - correct
answer-
