Exam III-SomatoSensory Receptors Flashcards
What are the receptors for Smell, Taste, and pH?
ChemoReceptors
What are the receptors for Light?
PhotoReceptors
What are the receptors for Temperature?
Thermoreceptors
What are the receptors for Pain?
Nocieptors
What are the receptors for touch, muscle length/force, auditory, and vestibular
MechanoReceptors
What is the translation of energy from external stimuli to an electrochemical signal?
Receptor Potential
What are the two structural types of receptors?
Encapsulated- surrounded by multiple layers of epithelial tissue and Non encapsulated
What are the two categories of adaptation?
Slow and fast
What are the TWO cell types that are NOT alpha-Beta innervated? What are their innervations?
Free Nerve Endings (alpha-Delta & C Fibers) and Hair Receptors (alpha-Delta)
What is the only receptor found on just hairy skin?
Hair Receptor!
What is the only receptor found on just glabrous skin?
Meissner’s Corpuscle
What are the only two purely slow receptors?
Merkel’s & Ruffini
What is the only rapid AND slow receptor?
Free Nerve ending
What are the three encapsulated receptor endings?
Meissener’s, Pacininan, and Ruffini
What is the process that helps localize a touch stimulus?
Lateral Inhibition
What type of receptor has Free nerve endings, Riffini’s, Paciniform corpuscles, and ligament receptors?
Joint Receptors
What are the two types of fibers involved with the muscle spindle? What are their innervations?
Nuclear Bag (Ia), and nuclear chain(II)
Ia VS II: Which is the dynamic response? Which is the slow and steady?
Ia: dynamic II: slow and steady
What type of motor innervation fibers at in intrafusal muscles?
gamma motor neurons
What type of sensory neuron is found in the aponeurosis of a muscle?
Golgi Tendon Organ
What is a monosynaptic reflex loop? How is it tested by the doctor?
Deep tendon reflex.. tested by the ole hammer to the knee
