The middle cranial fossa contains the.

A

majority of the sphenoid bone, including the sella turcia, which is the bony structure that houses the pituitary gland

28
Q

which is the bony structure that houses the pituitary gland

A

sella turcia— middle cranial fossa

29
Q

What vein can allow the transport of a retrograde infection originating in the superior labial vein region into the cavernous sinus.

A

Opthalmic vein

30
Q

How can the opthlamic vein allow the transport of a retrograde infection originating in the superior labial vein region into the cavernous sinus.

A

The inferior ophthalmic vein receives a small fraction of the drainage from the facial vein and the superior labial vein.

31
Q

Superficial temporal vein drains

A

the temporal region of the scalp and portions of the forehead.

32
Q

Does superficial temporal vein drain into the Superior sagittal sinus

A

no

33
Q

maxillary vein lies deep within

A

the infratemporal fossa and has no connections with the drainage from the superior labial vein

34
Q

venous drainage that lies deep within the brain. This vein does not drain any areas of the face, nor does it have direct connection with any vessels that drain the face.

A

The inferior sagittal sinus

35
Q

What covers the anterior surface of the cornea and sclera;

A

The bulbar conjunctiva

36
Q

lines the inner surfaces of the eyelids

A

the palpebral conjunctiva

37
Q

What covers the ciliary body which is part of the vascular tunic.

A

Ciliary epithelium

38
Q

What secretes aqueous humor into the posterior chamber of the eye.

A

The ciliary epithelium

39
Q

What is a layer of the eyelid between the layer of muscle and conjunctiva. It connects the tarsal plates to the margins of the orbit.

A

The orbital septum

40
Q

What two components make up the fibrous tunic of the eye.

A

Sclera and Cornea

41
Q

Cornea is vascular/avaslucar?

A

avascular and major refractive properties

42
Q

Vascular layer of eye includes:

A

Choroid, ciliary body and Iris

43
Q

the neural layer of the eye is

A

the retinal layer

44
Q

The anterior cavity contains

A

aqueos humor

45
Q

What nerves transmit postganglionic sympathetic fibers destined for the dilator pupillae muscle.

A

The long ciliary

46
Q

What nerve carries fibers that regulate lacrimation. It also carries taste fibers from the palate

A

nerve of the pterygoid canal

47
Q

What nerve trasnmits visual sensation from the retina to the thalamus.

A

The optic nerve

48
Q

General sensation from the orbit, specifically the conjunctiva, is transmitted by

A

the ophthalmic division of the trigeminal nerve via the lacrimal and frontal branches.

49
Q

infraorbital n. is a branch of ___ Although is supplies general sensation from the lower eyelid,

A

V2

50
Q

the location that the nasolacrimal duct drains into.

A

inferior nasal meatus

51
Q

The opening of the nasolacrimal duct is partially covered by a mucosal fold called the valve of Hasner within the

inferior nasal meatus.

52
Q

receives drainage from the sphenoid sinus and is found most superiorly in the nasal cavity.

sphenoethmoidal recess

53
Q

The nasal meatuses are continuous with the________ that extends down into the throat, but not the_________

A

nasopharynx

oral cavity.

54
Q

receives drainage from the maxillary sinuses via the semilunar hiatus, from the frontal sinuses via the frontonasal duct, and contains the ethmoidal bulla,

A

middle nasal meatus

55
Q

often the artery injured in a posterior epistaxis.

A

sphenopalatine artey as it passes through the sphenopalatine foramen in the posterior nasal cavity

56
Q

Because of its posterior location, damage to this blood vessel can cause drainage of the blood posteriorly into the throat.

A

sphenopalatine artery

57
Q

is a branch of the maxillary artery that supplies blood to the superior teeth and gums, but does not contribute to the nasal blood supply

A

posterior superior alveolar artery

58
Q

is a branch of the ophthalmic artery that travels inferiorly through the anterior ethmoidal canal to supply blood to the lateral wall and septum of the anterior nose.

A

anterior ethmoidal artery

59
Q

is a bilateral mucosal epithelium lined cavity that is located deep to the cheeks and inferior to the bony orbit.

A

he maxillary sinus

60
Q

Often, unilateral sinusitis can occur with infections, causing the backup of mucus, inflammatory debris, and infectious organisms within the cavity. This leads to pressure and discomfort felt in the area of the affected sinus. This patient’s sinus pressure in the cheek most closely corresponds with the

A

maxillary sinus.

61
Q

consists of numerous thin-walled mucosal epithelium-lined cavities that lie within the ethmoid bone. This bone is located in the superior portion of the nasal cavity and the lower portion of the orbits,
