Receptors may be defined as chemicals or the structure that has the ability to respond against the particular stimuli. Different physiological changes occur in the body after the sensing by the receptors.
Stretch receptors may be defined as the type of mechanoreceptors that regulates the blood pressure in the body. These receptors are located in the carotid artery and can sense the change in the blood flow and also linked with the nervous system of the body.
Since the options have not been provided the question is incomplete, the complete question is as follows:
Certain blood vessels that contain specialized sensors that detect the level of internal pressure and transmit messages to the nervous system, which then triggers the smooth muscle in the vessel walls to make any needed size adjustments, are called:
A) pressure receptors.
B) stretch receptors.
C) chemoreceptors.
D) volume receptors.
Answer: B) stretch receptors.
Explanation:
The stretch receptors are the mechanoreceptors these are responsible for connecting the organs and muscles with the neurologically to the medulla of the brain stem. These receptors are present in the arms and leg muscles which helps in stretching of the body. These are also present in the colon wall and the lungs for expansion in digestion and respiration process.
The given situation indicates that the adjustments of the smooth muscles in the walls of vessels is because of the stretch receptors.
People who have AB blood are considered "universal receivers" because they can take every single type of blood; their bodies can safety use A (because it already contains some A type blood), B (for the same reason), and O (because it is a neutral blood type).
An exotoxin is a toxic substance secreted by bacteria. The botulism exotoxin is the exotoxin secretes by bacterial strain named as Clostridium botulinum.
Point source outbreak is a condition in which people are exposed to the same source of infection from a pathogen. This may occur due to the consumption of a single meal which is being infected by the pathogen. This may lead to incidences of food poisoning, disease and even mass death.
