BIO 1306 Lecture Notes - Lecture 13: Signal Transduction, Neural Adaptation, Membrane Potential
Document Summary
The star-nosed mole can catch insect prey in near total darkness in as little as 120 milliseconds. It uses the 11 pairs of appendages protruding from its nose to locate and capture prey. Sensory processes convey information about an animal"s environment to its brain, and muscles and skeletons carry out movements as instructed by the brain. Concept 50. 1: sensory receptors transduce stimulus energy and transmit signals to the central nervous system. Sensation involves converting energy into a change in the membrane potential of sensory receptors. When a stimulus"s input to the nervous system is processed a ____________ may be generated. This may involve a simple reflex or more elaborate processing. Sensory pathways have four basic functions in common. Sensations and perceptions begin with sensory reception, detection of stimuli by sensory receptors. Sensory receptors interact directly with stimuli, both inside and outside the body.
