Benefits of Adaption in touch sensations - ️️1) Helps us to ignore constant, innocuous stimuli, reducing distraction 2) Helps to avoid saturation of neuronal firing rates, allowing us to detect changes in stimulus intensity over a larger ranger of intensities. Merkel Cells and Mechanotransduction - ️️When skin is presed: 1) Mechanically-gated ion channels in the A beta membrane open, letting in ions (Na) 2) This causes the first ("dynamic phase") action potential 3) Mechanically...

Enteric Plexus Correct Answer-Intrinsic nerves are located solely within the GI tract and are controlled by local and autonomic nervous system stimuli through the enteric plexus, which comprises 3 nerve plexuses located in different layers of the GI walls. -these enteric nerve circuits regulate motility reflexes, blood flow, absorption, secretions, and immune responses. Submucosal Plexus Correct Answer-Meissner plexus. Intrinsic nerve located soley in the GI tract and is controlled by the AN...

__________: impulses from the brain stem and spinal cord to the thalamus Correct Answer-Second-order neurons ________ learning occurs when a connection is made between two stimuli Correct Answer-Associative Present in ______muscle fibers are muscle spindles consisting of several slowly adapting _______ nerve endings that wrap around 3 to 10 specialized muscle fibers and detected changes in the muscle. Correct Answer-intrafusal / sensory ____ would detect irritation on the skin if you di...
