Chapter 7, Problem 18SAE
Summary Introduction
To review:
Identification of four cutaneous sensory receptors and description of sensations which they detect also to tell which is the most abundant sensory receptor and its physiological importance.
Introduction:
In the dermis and epidermis layer of the skin special sensory receptors are found which are known as the cutaneous receptors. Mainly the cutaneous receptor comprises those receptors which can detect pain, pressure, and temperature.

- What is the best physiological explanation as to why a particular area has a low two-point threshold? A greater skin surface area always results in a lower two-point threshold because there is physically more room in which to house sensory receptors. With a low two-point threshold, there is a greater density of sensory receptors to allow for more precise location of the sensation by the somatosensory cortex. O A low threshold suggests a decreased sensation in that area, meaning a wide receptive field on that area of skin.arrow_forwardRegarding the anterolateral pathway, (1) what type of sensory receptor is involved, and what type of sensory information is being provided to the brain, (2) what is the location of each of the sensory neurons within the chain of three neurons that compose this pathway, and (3) what specific region of the brain receives the sensory information?arrow_forwardHow does the sensory transduction mechanism in the vestibular and auditory systems demonstrate the importance of the general principle of physiology that controlled exchange of materials occurs between compartments and across cellular membranes?arrow_forward
- What are somatosensation and sensory transduction?arrow_forwarda) Based upon how the neural membrane functions, briefly explain how electrical stimulation can cause a neuron to generate an action potential. Describe in one sentence a type of action potential that can be generated by electrical stimulation, but that cannot be generated by synaptic inputs. b) The central part of the retina consists largely of cones, which are responsible for colour vision in normal sight. However, presently available retinal prostheses are not able to reliably provide a perception of colour for people implanted with these devices. Explain why people with a retinal prosthesis are currently unable to reliably perceive colour.arrow_forwardBased upon stimulus origin, would a cutaneous pain receptor beclassified as an exteroceptor, an interoceptor, or a proprioceptor?Based upon receptor distribution, would this same cutaneousreceptor be classified as a general somatic, general visceral, orspecial sense? Finally, how would this pain receptor in the skinbe classified based upon modality of stimulus?arrow_forward
- What structural type are the sensory nerves of pain in the skin ? (1) Tripolar (2) Unipolar (3) Bipolar (4) Motor (5) Multipolar (Please provide the answer with proper explanation)arrow_forwardSelect the statement that explains the neural mechanism underlying the sensation of fast, sharp pain followed by delayed, longer-lasting pain after an injury. a. Fast pain is conducted by mechanoreceptors, whereas delayed pain is conducted by fibers with free nerve endings. b. Fast pain is conducted by free nerve endings in the dermis, whereas delayed pain is conducted by deep nerve endings in the subcutaneous layer. c. The receptive fields differ for the two types of pain sensation such that fast pain fibers have smaller receptive fields than the delayed pain fibers. d. Fast and delayed pain represent the progression of the injury; both are conducted by the same fibers. e. Fast, sharp pain is conducted by myelinated axons, whereas delayed, longer-lasting pain is carried by unmyelinated axons.arrow_forwardGiven that touch receptors are not uniformly distributed on the body surface, name two sites where the highest density of receptors are found.arrow_forward
- 9) Describe the three types of afferent nerve fibers linked to nociceptors in terms of myelination, size and speed of transmission. How is pain modulated in the body? What is referred pain?arrow_forwardReceptor cells that are neurons with sensory dendrites are faster than receptor cells that are separate from neurons. Why is that, and why might that be important in, for example, the sense of touch versus vision?arrow_forwardThe velocity of conduction in a sensory fiber is dependent on axon diameter Omyelination length a) and b)arrow_forward
