chapter 6 Flashcards
what are the three forms of local communication
- gap junctions
- contact-dependent signals
- chemicals released in ECF
explain gap junctions
explain contact-dependent signals
explain chemical released in the ECF
what are the two forms of long-distance communication
- chemical signals
- electrical signals
explain chemical signals
explain electrical signals
what are the sequence of events that follow lipophilic ligand binding to intracellular receptors
what is the sequence of events for lipophobic ligand binding to a cell surface receptor
what are the four major groups of cell surface receptors
how do cascades play a role in signal transduction
how does signal amplification play a role in signal transduction
apply specificity to receptors and their ligands
apply competition to receptors and their ligands
apply affinity to receptors and their ligands
apply saturation to receptors and their ligands
what is the role of up-regulation in modulating cell responses to receptors and their ligands
what is the role of down regulation in modulating cell responses to receptors and their ligands
what is the role of pathway termination in modulating cell responses to receptors and their ligands
what Canon’s four postulates
give an example of each of canon’s four postulates
what are the seven steps of a reflex control pathway
compare the speed in neural and endocrine reflex
compare specificity in neural and endocrine reflex
compare types of signals in in neural and endocrine reflex
compare duration of action in neural and endocrine reflex
how is stimulus intensity coded in each type of reflex
