A

skeletal muscle, connective tissue and uvula

18
Q

types of pharyngeal arches

A

palatoglossal and palatopharyngeal

19
Q

where is the anterior tongue attached to

A

to floor via lingual frenulum

20
Q

what is the posterior tongue connected to

A

hyoid bone (via muscles) - not connected to any bone, epiglottis and oropharynx

21
Q

what is the pharynx

A

common passageway for food and air

22
Q

how is the pharynx connected to other systems

A

connected to respiratory system at larynx

connected to digestive system at oesophagus

23
Q

3 regions of pharynx

A

nasopharynx (behind nasal cavity)
oropharynx (behind oral cavity)
laryngopharynx (behind larynx)

24
Q

how is the pharynx lined?

A

ciliated pseudostratified columnar epithelium (nasopharynx)

moist stratified squamous epithelium (oropharynx and laryngopharynx)

25
Q

muscles in the pharynx

A

posterior walls of oropharynx and laryngopharynx
pharyngeal constrictors: superior, middle and inferior
helps push down the food down

26
Q

what is the oesophagus

A

muscular tube

continuation of the laryngopharynx superiorly and the stomach inferiorly

27
Q

what is the oesophageal hiatus

A

at the T10, hole that allows the oesophagus go through diaphragm - how it passes from the thoracic cavity into the abdominal cavity

28
Q

lining of oesophagus

A

moist stratified squamous epithelium

29
Q

layers of muscle of oesophagus

A

outer longitudinal and inner circular

30
Q

sphincters in oesophagus

A

upper oesophageal and lower oesophageal (cardiac)

31
Q

what is the cardiac

A

the lower sphincter in oesophagus - entrance to stomach

32
Q

where is the stomach situated

A

upper left abdominal quadrant

33
Q

what are the rugae

A

the folds in the stomach walls

34
Q

what is the fundus

A

the upper part of the stomach

35
Q

what is in the pyloric region of the stomach

A

pyloric antrum, canal, orifice, sphincter (pylorus) that surrounds the pyloric orifice

36
Q

what two structures does the pyloric sphincter divide

A

the stomach and small intestine

37
Q

lining of stomach

A

mucosa:

simple columnar epithelium

38
Q

how are gastric glands formed

A

by tube-like gastric pits formed by mucosa lining

39
Q

muscle layers of the stomach

A

outer longitudinal
middle circular
inner oblique

40
Q

why do muscles in the stomach have different directions

A

to be able to contract in any type of configuration

41
Q

what is the function of gastric glands

A

secrete hydrochloric acid, enzymes and hormones to digest the food
