Question
6. Using the following scenario, describe the role of the following sensory receptors:
Merkel Discs, Hair cells of the Macula, Gustatory receptors, Cone photoreceptor
Also be sure to list where each receptor is located and whether it is ionotropic or metabotropic.
You are up late studying vertebrate physiology and you suddenly feel hungry so you decide to walk towards the vending machine and after eyeing the snacks you opt for a candy bar. You place the money in the machine, press the button for your selection, then take a bite of your snack.
Explanation / Answer
SENSORY RECEPTORS:
These are the dendrites of sensory neurons. The sensory receptors are specialized for receiving specific kinds of stimuli. The sensory receptors are following types they are
These are the following types of sensory receptors.
The sensory receptors are two types
The ionotropic receptors are the receptors where the sensory stimulus gates the channel directly.
The metabotropic receptors are the receptors where the receptor activates the G- protein that can activate the ion channel.
MERKEL DISCS:
These are the modified free nerve endings. These are unencapsulated.
The location is EXTEROCEPTORS. These are ionotropic receptors.
Hair cells of the macula:
LOCATION: The location is within the utricle and saccule.
GUSTATORY RECEPTORS:
LOCATION: The gustatory receptors are located on the surface of the tongue. The function of the gustatory receptors is parallels the olfactory receptors.
These are metabotropic receptors.
CONE PHOTORECPTORS:
The cone photoreceptors are one of the three types of the photoreceptor cells.
LOCATION: These are located in the retina of the mammalian eye. These are responsible for the colour vision.
These are metabotropic receptors.
The sensory receptors that are located on the tongue are sending the stimulus when we take a bite of your snack. The receptors are gustatory receptors.
