Q

What is the difference between epidemic and pandemic?

A

Epidemic is due to antigenic drift (where the surface proteins slightly change) occuring in a set area

Pandemic is prevalent in a whole country or the world, occurring due to the complete changing of surface antigens

41
The stage of lung maturation that takes place between 6-16 weeks' gestation. It involves the development of multiple branches of the bronchial tree down to the level of the terminal bronchioles.
Pseudoglandular
42
The stage of lung maturation that takes place between 26 days' and 6 weeks' gestation. It involves the first stages of lung development, and sees the formation of the lungs' lobes and segments.
Embryonic
43
The germ layer that forms the cartilage and smooth muscle in the thorax.
Visceral mesoderm

What does the vagus nerve innervate?
The soft palate and intrinsic laryngeal muscles
45
What does stimulation of the glossopharyngeal and vagus nerve cause?
A cough reflex response
46
1. The stage of lung maturation that takes place between 16-28 weeks' gestation. It sees the branching of terminal bronchioles into respiratory bronchioles and finally alveolar ducts.
Canalicular
47
What germ layer forms the lining of the trachea and bronchial tree?
The endoderm
48
What is the first respiratory structure to develop
Respiratory diverticulum
49
What occurs during the pseudoglandular phase of lung developemnt
Bronchial branches are formed, occuring 6-16 weeks gestation
50
What stage of lung development is surfactant beginning to be produced
Saccular stage 28-36 weeks
51
What tumour produces keratin pearls and may produce thyroid transcription factor?
