BIO 365S Study Guide - Final Guide: Baroreflex, Stroke Volume, Lung Volumes
30 MC
8/9 MCMC
2 integrative questions
Types of transports and energy sources: Facilitated diffusion vs channel, what types of
molecules use what types of transport and types of energy.
Reflex pathway components: identify parts of a given pathway (insulin, which one is integrating
center – beta cells); 6 or 7 pathways, which hormones go with which.
Permissiveness, antagonism, synergism (hormone interactions).
Endocrine pathologies.
Graded potentials and action potentials (temporal and spatial summation), channels
responsible for different parts of the action potential.
-Neuro, autorhythmic, contractile action potentials.
Visual system, and lateral inhibition.
-Dark current, visual fields (types of input). Left field = left and right eye, right field = left
and right eye; left cortex = right field = both eyes.
Types of receptors used for branches of neurosystem, baroreflexes
Cardiac contractile cells (Ca2+ release). Compare normal skeletal muscle cells to cardiac
contractile cells.
-Plateau.
Autorhythmic cells: how they work, know the pathway (SA – AV, etc.).
-Paeaker, ats like a euro ut is’t, atually a usle ell that does’t at like a
muscle cell (NOT MODIFIED NEURONS, BUT MODIFIED CARDIAC MUSCLE TISSUE).
ECG components.
-Heart block pathology.
Stroke volume, MAP, pulse pressure. Simple calculation.
Factors that affect CO and SV:
Pressure-volume diagram.
Respiratory pathologies. Compare and contrast obstructive (increases residual volume) vs
restrictive disorders (decrease all lung volume) and how these affect the levels of oxygen
diffusion (the four levels).
-Left and right shift. Happens during exercise or diabetes with ketoacidosis = right shift
because increased temp/CO2, decreased pH, increased metabolites.
-Understand how altitude works: How it affects HbO2 curve and O2 saturation.
Autoregulation of GFR in kidneys: compare to systemic and neural control. (not much neural
regulation in GFR, mostly local).
-Where does secretion and reabsorption happen, and what types of transporters are
possible (SGLT).
Acid base: scenarios, pathologies.
-Type a and b cells, where their transporters go, what happens when they’re atiated,
hat side they’re goig to e o to affet ody aidity or asiity.
Renal hormones: is this hormone present or not present (scenarios)
