Answer 1

2. The vibrissae are the type of hairs grown around nostrils and are specialised for tactile sensation. The perpendicular plate of ethmoid is part of ethmoid bone. The Choanae are the two openings of the nasal passage. The nasal conchae ( also called turbinate) are the three bony folds that project from lateral walls towards septum. Hence option ( nasal conchae) is correct

3. Nasopharynx extends from nasal cavity to soft palate. The laryngopharynx is inferior portion connecting to larynx below. Oropharynx is the central portion that lies between soft palate and the top of the epiglottis. Hence option ( Oropharynx) is correct. 4. Cricoid cartilage is ring of cartilage that surrounds trachea. Arytenoid cartilage forms part of larynx. Corniculate cartilage are the accessory cartilage of larynx. Adam's apple is a part of larynx formed by thyroid cartilage( composed of hyaline cartilage). Hence option ( thyroid cartilage) is correct.

5. Tidal breathing also called quiet breathing involves the diaphragm, external intercoastal, and some portions of internal intercostals during the process of respiration. Hence option ( diaphragm, external intercoastal and internal intercostal) is correct. 6. Parietal pleura is a serous membrane attached to thoracic wall. Visceral peritoneum covers abdominal organs. Parietal peritoneum covers the abdominal cavity. Visceral pleura also called pulmonary pleura is a serous membrane attached directly to the surface of lung. Hence option ( visceral pleura) is correct.

8. Trachea and large bronchi is lined by ciliated pseudostratified columnar epithelial cells. Hence option (ciliated pseudostratified columnar) is correct. 9. The right lung consists of three lobes and left lung Two lobes. The left lung also has indentation on its surface called cardiac notch. Hence option ( right lung has three lobes and left has indentation called cardiac notch) is correct. 10. The trachea is held up by 16-20 C shaped rings. Hence the statement is ( true)
