Communication Systems Flashcards
what are the mediator molecules of the nervous system
Neurotransmitters that are released locally in response to nerve impulses
What is the site of mediator action in the nervous system
Close to the site of release, at the synapse, neurotransmitters bind to receptors in the postsynapticbmembrane
What are the types of target cells in the nervous system
Muscles, glands, and other neurons
What is the time to onset of action in the nervous system
Milliseconds - fast
What is the duration of action is the nervous system
Short term
What are the mediator molecules in the endocrine system
Hormones that are delivered to tissues throughout the body by the blood
What is the site of mediator action in the endocrine system
Far from the site of release, hormones bind to receptors on or in target cells
Whatare the types of target cells in the endocrine system
Cells throughout the body
What is the time to onset of action in the endocrine system
Seconds to hours or day - slow
What is the duration of action in the endocrine system
Generally longer
