As part of the “fight-versus-flight” response, the sympathetic nervesinnervate the heart, blood vessels, bronchi, and GI tract. Sympathetic neurons have short preganglionic fibers that synapse at ganglia (celiac, superior mesenteric, inferior mesenteric, and hypogastric) outside the GI tract. W...
If the MEMBRANE potential is not at the equilibrium potential for a given ion, then there will be a driving force on that ion. TTX Blocks Na+ Channels Frog toxins cause channels to OPEN At more negative potentials! Electrical Synapse electrical synapses use direct electrical connections between ...

What is ethology? What is orthopedic biomechanics? What is serotonin? What is occupational biomechanics? What is bioinformatics? What is a cholinergic synapse? What are lectins in biochemistry? What is oxytocin? What is cognitive flexibility training?
What are the feedback loops within the nervous system that have the effect which a two-way synapse would have if it existed? What is the function of epinephrine? How does the skin respond to external stimuli? What does dopamine do?
1. neurons communiste with each other by sending neurotransmitters across the synapse between the axon &dendrites of nearby membranes2. neurotransmitters use the lock-&-key theory to bind with receptor sites on dendrites3. Na/K pump opens channel for action potential to move4. AP reaches the ve...

What are activated and reactive glia and what is their role in neurodegeneration? Reactive astrocytes variably undergo process hypertrophy, decrease their normal homeostatic functions such as facilitating synapse formation, and in some cases act to form a tissue scar in response to insult. But what ...
Learning in the human brain is not compartmentalised into ‘cognitive’ and ‘affective’. Long-term memory is closely associated with the part of the brain called the hippocampus, which itself is also associated with emotions [43]. Correspondingly, a longstanding finding from psychology is that ...
When properly signaled by incoming messages, vesicles release their load of neurotransmitters through terminal buttons, bulbous structures at the end of each axon, where they travel across a synapse, a gap between the axon of one neuron and the dendrites of another. ...
