RCA lecture 1 nerve

Question 1

whats the branches of the opthalmic nerve and where does it exit the cranial vault

Answer 1

opthalmic is trigeminal branch one remember,
this is a wholly sensory branch. its branches are the frontal nerve, lacrimal nerve, nasociliary. all going into the orbit via the superior orbital fissure

Question 2

tell me about the path and the function of the lacrimal gland

Answer 2

passess laterally to the lacrimal gland, supplies the lateral skin and conjunctiva of upper eyelid

Question 3

what are the branches of the frontal nerve , and whats the frontal nerve a branch from itself

Answer 3

the frontal nerve comes from the opthalmic branch of the trigeminal nerve. its branches are the supraorbital and supratrochlear nerve

Question 4

what does the frontal nerve supply

Answer 4

the upper eyelid, forehead and scalp

Question 5

whats the branch of the nasociliary nerve anmd whats it a branch of itself

Answer 5

gives rise to the external nasal nerve, it branches off of the opthalmic nerve from the trigeminal

Question 6

whats the nasociliary nerve supply

Answer 6

nasociliary does the eye
the external nasal nerve does the skin of the dorsum of the nose

Question 7

what are the branches of the maxillary nerve

Answer 7

zygomatic nerve and the posterior superior alveolar nerve

Question 8

whats the path of the maxillary nerve

Answer 8

it becomes the infraorbital nerve after entering the orbit via the inferior orbital fissure, runs along floor of orbit then to the face via the infraorbital foramen

Question 9

whats the nerve supply of the infraorbital nerve

Answer 9

sensation to lower eyelid, cheek and upper lip

Question 10

tell me the path of the zygomatic nerve

Answer 10

comes from the maxillary nerve after going through the inferior orbital fissure. this one runs on the lateral wall of the orbit. emerges on the face through a foramen in the zygomatic bone

Question 11

what is the supply of the zygomatic nerve

Answer 11

the skin over the zygomatic arch

Question 12

what does the mandibular nerve divide into

Answer 12

the medial pterygoid nerve and then the anterior and posterior branches

Question 13

what are the anterior branches of the mandibular nerve

Answer 13

all motor except the buccal nerve,
the others are the lateral pterygoid, temporalis and masseter

Question 14

what are the posterior branches of the mandibular nerve

Answer 14

all sensory except the mylohyoid nerve
the others are the auriculotemporal, lingual and the inferior alveolar

Question 15

where does the auriculotemporal nerve supply

Answer 15

sensory supply to the skin of the temporal region

Question 16

whats the buccal nerve supply

Answer 16

the cheek

Question 17

whats the mental nerve supply

Answer 17

chin and lower lip

Question 18

whats the mental nerve a branch of

Answer 18

terminal branch of inferior alveolar nerve, emerging from the mental foramen

Question 19

whats the cervical plexus roots

Answer 19

C1-C4

Question 20

whats the cervical sensory supply

Answer 20

anterior and lateral neck, lateral head

Question 21

whats the greater auricular nerve

Answer 21

a branch of the cervical plexus, skin of auricle and angle of mandible

Question 22

whats the nerve roots of the greater auricualr nerve

Answer 22

C2-C3
