Understand basic mechanisms of receptor regulation Desensitization, homologous or heterologous Spare receptors -1- OVERVIEW OF AUTONOMIC PHARMACOLOGY PHARMACOLOGICAL (NOT ANATOMICAL) DIVISION OF PNS: Cholinergic vs. Adrenergic Cholinergic: All preganglionic and parasympathetic postganglionic Acetylcholine is the neurotransmitter at ganglia, nmj, and muscarinic tissue synapses Adrenergic: Postganglionic sympathetic neurons (most). Norepinephrine is the transmitter Exceptions: Cholinergic transmission in sympathetic system - all ganglia, adrenal medulla, sweat glands (muscarinic)…
1. Acetylcholine is released by the axon terminal, diffuses to the muscle cell and attaches…

5. Cerebellum- The area located directly behind the brainstem. It processes sensory input, organizes movement, helps sustain balance, and implements nonverbal learning and memory.…
It is expected to recognize a threshold of the daphnia in its reaction the three different adrenalin concentrations, in terms of heart rate.…
3. Describe how the sympathetic and parasympathetic nervous systems work together to regulate the heart rate.…
The autonomic nervous system (ANS) consists of two divisions, each innervating the effector organs. The sympathetic nervous system (SNS) generally speeds up everything except digestion. The parasympathetic nervous system (PNS) generally slows down everything but digestion.…
