Quiz 10 Flashcards
The (name for wind pipe) is the largest conduit for air flow.
trachea
The ________ and the _______ have smooth muscles that surround the tubular structures. Are also conduits for air flow.
bronchi/ bronchioles
The autonomic nervous system plays a significant role in regulating the diameter of these structures, with the sympathetic nervous system, through Norepinephrine and Epinephrine causes (bronchodilation or bronchoconstriction) of these structures
bronchodilation
The parasympathetic nervous system, through innervation of vagus nerve causes (bronchodilation or bronchoconstriction) of these structures
bronchoconstriction
Irritants in the air or inflammatory mediators, such as histamine or leukotrienes can cause (bronchodilation or bronchoconstriction).
bronchoconstriciton
To create the changes in pressures that permit inspiration, there must be a decrease in both the intrapulmonary pressure and the intrapleural pressure. What two muscle groups must contract to create this change?
external intercostal muscles and diaphragm
Group of muscles that are involved in forceful expiration.
internal intercostal muscles
The receptor for taste is the gustatory cell and is located in a pore on the taste bud. This is innervated by the cranial nerves VII and IX. (T/F?)
True
The lateral line system in fish serves as their senses of taste and smell. Through the movement of water through pores along the lateral line system, they are able to detect movement, magnetic fields, and in some fish detect electrocurrents. (T/F?)
True
The middle ear includes the horizontal canal, the tympanic membrane, ossicles, and the oval window. Cranial nerve VI innervates the ear. (T/F?)
False
Going from the outer ear to the inner ear, sounds start as waves in the air, then become mechanical movements through the interaction of the ossicles with the tympanic membrane, then become fluid waves in the inner ear, with final transfer as nervous impulses to the brain in the organ of corti. (T/F?)
True
The tapetum lucidum is found between the lense and the retina to intensify the light as it passes on its way to the retina. This is a system that is especially helpful for night-time vision of humans, and of relative help to animals such as cats. (T/F?)
False
