Solution to example 2. 1  multiply all terms in the first equation by 2. 2  add the two equations. 3  Conclusion: Because there are no values of x and y for which 0x + 0y = 11, the given system of equations has no solutions.
Baroreceptors (or archaically, pressoreceptors or baroceptors) are sensors located in the blood vessels of all vertebrate animals.hey sense the blood pressure and relay the information to the brain, so that a proper blood pressure can be maintained. Baroreceptors are a type of mechanoreceptor sensory neuron that is excited by stretch of the blood vessel.
the saccule and utricle The sensory receptors for static equilibrium are located in structures called maculae (singular is macula), which are found in the saccule and utricle. The macula sacculi lies nearly vertically in the wall of the saccule, and the macula utriculi lies almost horizontally on the floor of the utricle. These receptors take notice when our bodies move faster or slower in a forward or backward direction.
