Chapter 43.5, Problem 6LO
Summary Introduction
To compare: The functions and mechanisms of action of the following mechanoreceptors: tactile receptors, proprioceptors, statocysts, hair cells, and lateral line organs.
Introduction: Mechanoreceptors are the sensory receptors that are activated in response to any change in shape caused due to mechanical pull or push. They help animals to maintain balance and hear or feel things. They are also useful in detecting the external environment by identifying the shape, texture, and height of objects. Main types of mechanoreceptors are: tactile receptors, proprioceptors, statocysts, hair cells, and lateral line organs.

Describe each of the following types of receptors, indicating what sensation it detects and giving an example of where it can be found in the body: pain receptors (nociceptors), temperature receptors,mechanoreceptors (including proprioceptors and barorceptors/pressoreceptors), chemoreceptors, and photoreceptors.
Fill out the information indicated for tactile receptors in the table below:

- Select all of the statements that are true about gustation: The papillae on the tongue are the receptor cells for taste molecule stimuli. Salt and sour taste stimuli sense Na+ ions and H+ ions respectively. In order for sweet tastes to be sensed, the taste molecule must first bind to a protein receptor in a taste bud. The gustatory pathway for the processing of taste stimuli are relayed to the thalamus, and then to the gustatory cortex for processing by the brain.arrow_forwardIdentify the three classes of mechanoreceptors.arrow_forwardIn the process of sensory coding Recruitment of additional neurons occurs with a weak stimulus in order to make the stimulus stronger. The larger the receptive field of a sensory receptor, the greater the expected acuity and the more accurate the two-point discrimination. Lateral inhibition of neighboring receptors resulting in a relative reduction of action potentials in the neighboring second order neurons would be expected to increase acuity. A receptor potential that remains suprathreshold into the absolute refractory period will result in additional action potentials.arrow_forward
