A person who has the condition CIPA is unable to feel pain or temperature. Which sensory receptors are affected by this condition?
photoreceptors and thermoreceptors
chemoreceptors and photoreceptors
thermoreceptors and mechanoreceptors
mechanoreceptors and chemoreceptors
Plz help me
Oh and,
Which observation could you make based on stimuli to your photoreceptors?
This apple is cold.
This apple is tart.
This apple is light.
This apple is red.
Apple is red its easy thats why they call it photo-receptors
To determine which sensory receptors are affected by the condition CIPA (Congenital Insensitivity to Pain with Anhidrosis), we need to understand the roles of different sensory receptors in the body.
CIPA is a rare genetic disorder that affects the peripheral nervous system. It leads to the inability to feel pain, temperature, and often results in anhidrosis (the inability to sweat).
Pain and temperature sensations are detected by specialized sensory receptors called nociceptors and thermoreceptors, respectively. Nociceptors, also known as pain receptors, are responsible for sensing pain, while thermoreceptors are responsible for detecting temperature changes.
Therefore, in the case of CIPA, the sensory receptors that are affected are thermoreceptors, which detect temperature changes, and nociceptors, which detect pain.
Now, let's go over the given options and identify the correct answer:
- photoreceptors and thermoreceptors: While photoreceptors are responsible for detecting light and are found in the eyes, they are not relevant to the condition CIPA. So, this option is incorrect.
- chemoreceptors and photoreceptors: Chemoreceptors are sensory receptors responsible for detecting changes in chemical concentrations, such as those involved in taste and smell. Since chemoreceptors are not directly related to pain or temperature sensation, this option is also incorrect.
- thermoreceptors and mechanoreceptors: This option includes the thermoreceptors, which is correct since they detect temperature changes. However, mechanoreceptors detect mechanical stimuli like touch, pressure, and vibration, which are not affected in CIPA. Therefore, this option is partially correct but not the best answer.
- mechanoreceptors and chemoreceptors: This option includes mechanoreceptors, which are not directly related to pain or temperature sensation. Moreover, we have already discussed that chemoreceptors are responsible for detecting chemical concentrations rather than pain or temperature. Hence, this option is incorrect.
Therefore, the correct answer is: thermoreceptors and nociceptors (also known as pain receptors).
I hope this explanation helps!
