18 Questions
What type of nerves do catecholamine fluorescence show?
Sympathetic nerves
Which of the following stimuli may cause salivary secretion?
Gustatory
What is the relationship between salivary flow rate and masticatory forces?
Salivary flow rate is directly proportional to masticatory forces
Who first studied the masticatory-salivary reflex in man?
Lashley
What type of nerve endings are implied in the periodontal ligament?
Ruffini endings
What is the primary difference between Parotid saliva and Submandibular/sublingual saliva?
Parotid saliva has a higher flow rate than Submandibular/sublingual saliva.
What is the effect of olfactory stimulation on salivary flow rate?
It increases salivary flow rate in both Parotid and Submandibular/sublingual glands.
What is the name of the reflex that occurs when chewing on one side stimulates saliva secretion on the same side?
Masticatory-salivary Reflex
What is the term for the phenomenon where a stimulus that is not normally associated with salivation can cause salivation?
Conditioned reflex
What is the primary difference between a conditioned reflex and a true reflex?
A conditioned reflex is a learned response, while a true reflex is an innate response.
What is the primary reason why the 'mouthwatering' sensation is not considered a true reflex?
It is an involuntary response, but it is not associated with an increase in salivary flow rate.
Which of the following is NOT a type of salivary gland?
Minor gland
What type of salivary glands are affected by the olfactory-submandibular salivary reflex?
Submandibular glands
Which of the following odors had the highest flow rate in the submandibular salivary glands?
Vanilla
What is the name of the scientist who received the Nobel prize in 1904 for his studies on reflex salivary and gastric control?
Pavlov
What is the term for the process by which the brain learns to associate a neutral stimulus with an unconditioned stimulus to elicit an unconditioned response?
Classical conditioning
What is the term for the flow rate of saliva in the parotid gland?
ml/min
What is the name of the reflex that is elicited by the stimulation of gustatory receptors in the taste buds?
Gustatory-salivary reflex
This quiz covers the physiology of the oral cavity, including the masticatory reflex, gustatory-salivary reflex, and the role of taste buds in salivary secretion. It also explores the basic tastes and their effects on salivary secretion.
