1

what is the innervation of the naso, oro and laryngopharynx

naso= maxillary V2
oro= glossopharyngeal
laryngo= vagus

2

what nerve supplies motor innervation to stylopharyngeus

glossopharyngeal

3

what nerve supplies motor innervation to cricothyroid

external branch of superior laryngeal

4

origin and insertion of pec major

origin= medial clavicle and sternocostal head
insertion= lateral lip of bicipital groove

5

origin and insertion of pec minor

origin= ribs 3-5
insertion= coracoid process

6

origin and insertion of serratus anterior

origin= upper 8 ribs
insertion= vertebral border of scapula

7

innervation of pec major, minor and serratus anterior

major= medial and lateral pectorals
minor= medial pectoral
serratus= long thoracic nerve

8

what travels through diaphragm at T8, T10 and T12

T8= right phrenic and vena cava
T10= vagus and oesophagus
T12= aorta and thoracic duct

9

role of clara cells

detoxification of pollution and role in controlling inflammatory response

10

final branch of the bronchioles

respiratory bronchioles, terminal bronchioles come before respiratory

11

are azygos veins left or right side of the body

azygos are right and hemiazygos are left

12

what are the routes of the two recurrent laryngeals

right= loops under right subclavian and between trachea/ oesophagus
left= loops under aorta and ascends between trachea/oesophagus

13

what is the drainage of the frontal and maxillary sinuses

hiatus semilunaris of middle meatus

14

what is the drainage of the sphenoid sinus

sphenoethmoidal recess lateral to attachment of nasal septum

15

what is the action of the pec major minor and serratus anterior

major= adduction and medially rotates humerus
minor= draws scapula and forearm forwards
serratus= protraction of the scapula

16

where is the pulmonary artery in relation to the bronchus in the right and left lungs

RALS
right= anterior to bronchus
left= superior to the bronchus

17

what level is the horizontal fissure of the lung

5th rib`

18

what may you find at T4-T5 at transverse plane

sternal angle
bifurcation of trachea
costal cartilage and rib 2
arch of aorta starting and ending
T4/T5 also divides the mediastinum into superior and inferior

19

where are the heart sound locations

aortic valve= right of sternum- 2nd intercostal space
tricuspid valve= left of sternum 5th intercostal space
pulmonary valve= left of sternum 2nd intercostal space
mitral valve= left mid-clavicular 5th intercostal space

20

insertion of the sternocleidomastoid

mastoid process of temporal bone

21

what the 4 infrahyoids

TOSS
thyrohyoid
omohyoid
sternohyioid
sternothyroid

22

what two valves are the AV valves

tricuspid and mitral

23

what two valves are the semi lunar valves

pulmonary and aortic

24

how are papillary muscles attached to the valves

chorda tendinae

25

what is the only artery in the body to carry deoxygenated blood

pulmonary artery

26

how many pulmonary veins do we have

4

27

the right atrium is made up of smooth and trabeculated portions, where do they come from

smooth arises from sinus venosus and trabeculated is from the original atrium

28

what seperates the smooth and trabeculated portions of the right atrium

crista terminalis

29

what lies under the crista terminalis

sino-atrial node

30

what is the fossa ovalis a remnant of

foramen ovale
