Have your partner stand with his or her eyes closed and arms

Have your partner stand with his or her eyes closed and arms at his or her sides for several seconds. Evaluate his or her ability to remain balanced. Hold an unknown sample near your partner\'s nose, and fan the odor toward him or her by waving your hand over the container. Have him or her identify the substance by its scent. Evaluate your partner\'s ability to taste using papers. Have your partner place a piece of PTC paper on his or her tongue and determine if he or she can taste it (the ability to taste PTC is genetically determined: about half of the population can taste it). If your partner cannot taste the PTC, try the theorem paper instead (a word of warning theorem tastes bad). If your partner cannot taste either of these papers, try the sodium benzoate paper.

Solution

11. observation: When he is made to close his eyes and stand still, hands by his side, the subject tries to maintain its balance and sways in a direction of pendulum. The test goes positive if the test gives the swaying of the subject or he falls down. The test is performed for the test of the loss of the motor coordination.

The CN(s) that is the tested by the test is the motor coordination cells of the brain. if the test is positve it is said that the coordination is cerebellar in nature.

12. Observation: The test determines the ability of sense of smell. the subject detects the correct odor when the smell is waved by hand around the nose. If the smell is sniffed it may harm the mucous membrane of the nose. The Odour test is done for the olfactory nerve or the CNI that has the nerve fibers for the smell.

13. Observation: Since the taste of PTC is bitter or appears tasteless to the tester according to the genetic makeup of the testing person. It appears tasteless to him that means he cannot taste the PTC and is recessive for the trait. The test confirms that the taste of the subject is governed by the PNS and send the signals to the CNS.
