Q

What is the pathway of the maxillary branch of the trigeminal nerve

A

exits the cranial cavity through the foramen rotundum and enters the pterygopalatine fossa. it exits by transversing the inferior orbital fissure and it enters the orbit where it continues as the infraorbital nerve.

Q

what does the anterior superior alveolar nerve innervate?

A

maxillary canines and incisors

23
Q

what are the branches of the mandibular division of the trigeminal nerve?

A

lingual, buccal, chorda tympani (branch of facial), auriculotemporal, inferior alveolar

24
Q

what is the pathway of the mandibular division of the trigeminal nerve?

A

enters the infratemporal fossa from the foramen ovale

25
Q

what does the buccal branch innervate?

A

sensory info from mucosa of the cheek

26
Q

what does the auriculotemporal branch innervate?

A

sensory info from skin of anterior scalp, it also provides a route for autonomic fibres to reach the parotid gland

27
Q

what does the inferior alveolar nerve innervate?

A

mandibular teeth, mylohyoid muscle and anterior belly of digastric

28
Q

what is the path of the inferior alveolar nerve

A

before entering the mandibular canal it gives off the motor branch to mylohyoid innervating the anterior belly of digastric and mylohyoid. it emerges from mental foramen and continues as mental nerve that innervates skin of the chin.

29
Q

what is the clinical relevance of the pterygomandibular raphe

A

used as a guide to anaesthetize the inferior alveolar nerve and therefore all the lower teeth

30
Q

what is the sphenomandibular ligament

A

connects the sphenoidal spine to the medial side of the ramus

31
Q

which branch of the mandibular nerve innervates the TMJ

A

auriculotemporal

32
Q

what are the functions of the lingual nerve

A

sensory info from anterior 2/3 of tongue
taste sensation of anterior 2/3 of tongue
autonomic fibres to submandibular and sublingual glands

33
Q

what is the function of the inferior alveolar nerve

A

sensory info on chin, innervate all lower teeth

34
Q

what are the 3 functions of auriculotemporal nerve

A

innervate skin of anterior scalp
route for autonomic fibres to reach parotif salivary gland
sensory info from TMJ

35
Q

what nerve gives sensory info from mucosa of lower lip, cheecks, teeth, gingiva and floor of the mouth?

A

mandibular

36
Q

which nerve gives sensory info from mucosa of upper lip, cheeks, teeth, gingiva and roof?

A

maxillary

37
Q

which nerve gives sensory info from boundaries of fauces?

A

glossopharyngeal

38
Q

what branches of the maxillary artery supply the oral cavity?

A

inferior alveolar artery
buccal artery
posterior superior artery
infraoribital artery
descending palatine artery

39
Q

what does the inferior alveolar artery supply?

A

mandible, mandibular teeth, mylohyoid

40
Q

What does the buccal artery supply?

A

buccal mucosa

41
Q

what does the posterior superior alveolar artery supply

A

maxillary molar, premolar teeth, and gingiva

42
Q

what does the infraorbital artery supply?

A

maxillary canines and incisors (through the anterior superior alveolar branch)

43
Q

what does the descending palatine artery supply?

A

mucosa and glands of soft and hard palate

44
Q

which veins are tributaries of the pterygoid venous plexus

A

posterior superior and inferior alveolar veins, infraorbital veins, buccal veins

45
Q

what are the superficial tissues of lymphatic drainage

A

cheek, upper lip, lower lip, mucosa of floor of mouth, tip of tongue

46
Q

where does the cheek and upper lip drain into

A

submandibular and sometimes buccal lymphnodes first

47
Q

where does the lower lip drain into

A

submandibular and submental lymph nodes

48
Q

where does the mucosa of the mouth and tip of tongue drain into

A

submental nodes

49
Q

where does the gingiva drain into

A

submandibular lymph nodes

50
Q

where do the teeth drain into

A

mandibular incisors submental and all other teeth submandibular lymph nodes

51
Q

where does the rest of the tongue drain into

A

directly to nodes of deep chain (except for centre dorsum of tongue)

52
Q

Function + structure of the hard palate

A

Made up of bone + covered with a layer of keratinized squamous epithelium

This creates a strong rigid structure for the roof of the oral cavity allowing the tongue to press food against it to push food towards the teeth for the further breakdown or manipulate the bolts before swallowing

53
Q

Function + structure of soft palate

A

Made up of skeletal muscle (therefore soft tissue)

While swallowing will contract to close the nose pharynx preventing food or liquid from entering the nasal cavity
