Question

Select the correct statement(s):

Answer 1

Answer:

The correct option is B Pressure-sensitive baroreceptors uses tonic receptors which adapt slowly to the stimulus

Explanation:

a. The thalamus receives stimulus from all of the five senses (sight, smell, taste, hear, touch). FALSE. Olfactory information is not sent to the thalamus for its process. The rest is.  

b. Pressure-sensitive baroreceptors uses tonic receptors which adapt slowly to the stimulus. TRUE. Among the different types of tonic receptors, we may find baroreceptors, irritation receptors, tactile receptors, and proprioceptors. Tonic receptors characterize by their slow adaptation to the stimulus. The first discharge is maximal when the stimulus is received and then it progressively decreases. They send a continuous signal to the CNS.

c. The three layers that the retina is made of: photoreceptors, bipolar cells, rod cells. FALSE. There are in fact three layers in the retina: photoreceptors, bipolar cells, and ganglion cell layers. NOT rod cells.  

d. The sense of smell uses phasic receptors which continuously fire as long as the stimulus is present. FALSE. Olfactive sense uses phasic receptors, but not continuously. These receptors shoot when they receive the stimulus, and then cease if the stimulus keeps constant.
