Unformatted text preview: BIPN 100 Chris Childers Dr. Fortes Winter 09 Lecture 11 February 2 nd Lecture 12 February 4 th Sensory Receptors Tonic vs. Phasic Fine touch vs. pain receptors Rubbing a wound - Why does it feel good? Sympathetic vs. Paraympathetic Nervous Systems Pre-ganglionic vs. post-ganglionic neurons Adrenergic receptors Adrenal Cortex Compare and contrast tonic versus phasic receptors. Give some examples of each. Tonic Receptors as long as the stimulus is present, the receptor will respond to the stimulus. Examples stretch receptors, proprioception receptors, baroreceptors, chemoreceptors etc. Phasic Receptors not monitored continuously, olfaction for example Tonic receptors are slowly adapting receptors that respond for the duration of a stimulus Phasic receptors rapidly adapt to a constant stimulus and turn off. They fire once more when the stimulus turns off. Compare and contrast fine touch / proprioception receptors with pain / temperature receptors. How is signal information translated in the spinal chord? Where do the signals cross to the contralateral side? Which fibers are they carried by?...
