Plant Physiology Test quiz and
answers graded A+
Tonic control - ANS✅✅regulates physiological parameters in an up-down fashion; signal always
present but changes intensity
Antagonistic control - ANS✅✅uses different signals to send a parameter in opposite directions
2 types of reflex pathways - ANS✅✅nervous and endocrine
Response loop - ANS✅✅stimulus- sensor/receptor- input signal- integrating center- output signal-
target- response
Stimulus- - ANS✅✅disturbance/change that sets pathways in motion
Sensor - ANS✅✅monitors environment for a variable
Integrating center - ANS✅✅compares input to setpoint and decides if output needed
output= - ANS✅✅efferent
input= - ANS✅✅afferent
central receptors are - ANS✅✅special senses
peripheral receptors are - ANS✅✅somatosenses
general systemic response describes - ANS✅✅what the specific cellular tissue events to organism
as a whole
neuroendocrine pathway - ANS✅✅neuron creates an electrical signal, but the chemical released
by the neuron is NEUROHORMONE that goes into the blood for general distribution
, neurohormone connections - ANS✅✅hypothalamus connects to pituitary by infundibulum
anterior pituitary = adenophysis
posterior pituitary = hypophysis
two sides to pituitary gland - ANS✅✅
neurotransmitter (in most pathways) - ANS✅✅released by neurons into extracellular fluid for
communication between cells
neurotransmitter (in few pathways) - ANS✅✅electrical signals pass directly from cell to cell
through gap junctions
emergeant properties - ANS✅✅complex processes that cannot be predicted from what we know
about properties of individual nerve cells and their specific connections
Action potential - ANS✅✅conduction signal
Axon - ANS✅✅nerve fiber
Central Nervous System (CNS) - ANS✅✅brain/spinal chord
Peripheral Nervous System (neurons) - ANS✅✅sensory (afferent) neurons and efferent neurons
CNS doesn't need - ANS✅✅input or to create measurable output to efferent divisions
synapse - ANS✅✅connection btwn presynaptic neuron and post synaptic cell/neuron
electrical synapse - ANS✅✅presynaptic and postsynaptic cells are connected by gap junction
channels
hyperpolarize - ANS✅✅increase of K+ permeability = cell becomes more negative
