front 7 What type of cells are in the inner lining of the trachea? | back 7 pseudostratified ciliated columnar epithelium (with goblet cells) |
front 8 What divides the nasal cavity sagitally? | back 8 the nasal septum |
front 9 What bones form the roof of the nasal cavity? | back 9 Ethmoid & sphenoid |
front 10 What prevents liquid from going into the larynx? | back 10 Epiglottis |
front 11 What type of cells make up the three regions of the pharynx? | back 11 1) nasopharynx- pseudostratified columnar epithelium with goblet cells.
|
front 12 True or false: the openings of the auditory tube (eustachian tube) are in the nasopharynx? | back 12 True! |
front 13 True or false: the oropharynx is shared with the digestive system | back 13 True! |
front 14 What are the three types of UNPAIRED cartilages in the larynx? | back 14 thyroid, cricoid, epiglottis (attached to thyroid) |
front 15 What type of cartilage is the epiglottis made of? | back 15 Elastic cartilage |
front 16 What are the three types of PAIRED cartilage in the larynx? | back 16 Arytenoids (attached to cricoid), corniculate (attached to arytenoids), cuneiform (contained in mucous membrane) |
front 17 True or false: the false vocal cords are involved in sound production | back 17 False (the true vocal cords are involved in sound production) |
front 18 What is opening of the vocal cords called? | back 18 The glottis |
front 19 How many c-shaped hyaline cartilage rings are in the trachea? | back 19 15-20 |
front 20 The most inferior tracheal cartilage forms a ridge which separates the openings into the main bronchi. This is called the: | back 20 carina |
front 21 The two primary bronchi meet to form the: | back 21 trachea |
front 22 What does a tertiary bronchus divide in to? | back 22 Bronchioles |
front 23 What structure in the lungs is the site of oxygen exchange with the blood stream? | back 23 alveoli |
front 24 What are the three types of cells in respiratory membrane? | back 24 1) Type I pneumocytes (thin squamous epithelial)
|
front 25 What cells in the lungs are not mature in pre-term babies? | back 25 Type II pneumocytes- they are not mature enough to produce surfactant in pre-term babies |
front 26 What are the parts of the lungs? | back 26 Base, apex, hilus, lobes |
front 27 True or false: each lung has 3 lobes. | back 27 False- the right lung has 3 lobes, the left lung has 2 lobes |
front 28 Name the fissures in the right lung | back 28 oblique fissure, horizontal fissure |
front 29 Name the fissures in the left lung | back 29 oblique fissure (there is only one fissure since there are only two lobes in the left lung) |
front 30 True false: the cardiac notch is located on the right lung | back 30 False: the cardiac notch is on the LEFT lung (this is thought to be why the left lung only has 2 lobes) |
front 31 Name the muscles involved in INSPIRATION | back 31 Scalenes, pectoralis minor, external intercostals, diaphragm |
front 32 Name the muscles involved in EXPIRATION | back 32 Internal intercostals, abdominal muscles |
front 33 Which muscle in the PRIMARY muscle of inspiration? | back 33 The diaphragm |
front 34 What is the region between the two pleural cavities? | back 34 The mediastinum |
front 35 True or false: the mediastinum contains the contents of the thoracic except for the lungs | back 35 true |
front 36 Which pleura is adherent to the lungs: visceral or parietal? | back 36 Visceral pleura |
