Eye

Question 1

palpebral fissure

Answer 1

elliptical opening between the eyelids and is the entrance into the conjunctival sac

Question 2

glands of Zeis

Answer 2

• sebaceous glands

- open directly into the eyelash follicles

Question 3

ciliary glands (glands of Moll)

Answer 3

modified sweat glands that open sepa- rately between adjacent lashes

Question 4

tarsal glands

Answer 4

are long, modified sebaceous glands that pour their oily secretion onto the margin of the lid; their openings lie behind the eyelashes, This oily material prevents the over- flow of tears and helps make the closed eyelids airtight

Question 5

lacus lacrimalis

Answer 5

The more rounded medial angle is separated from the eyeball by a small space

Question 6

caruncula lacrimalis

Answer 6

a small, reddish yellow elevation in the center of lacus lacrimalis

Question 7

plica semilunaris

Answer 7

A reddish semilunar fold, that lies on the lateral side of the caruncle

Question 8

papilla lacrimalis

Answer 8

Near the medial angle of the eye a small elevation

Question 9

punctum lacrimale

Answer 9

small hole on the summit of the papilla which leads into canaliculus lacrimalis

Question 10

The upper lateral part of the superior fornix is pierced by

Answer 10

the ducts of lacrimal gland

Question 11

subtarsal sulcus

Answer 11

its the groove beneath the eyelid, which runs close to and parallel with the margin of the lid, The sulcus tends to trap
small foreign particles introduced into the conjunctival sac and is thus clinically important

Question 12

medial palpebral ligament attaches to

Answer 12

the crest of the lacrimal bone

Question 13

lateral rectus is supplied by

Answer 13

abducent nerve (VI)

Question 14

superior oblique is supplied by

Answer 14

trochlear nerve (IV)

Question 15

Superior rectus action

Answer 15

Raises cornea upward and medially

Question 16

inferior rectus action

Answer 16

Depresses cornea downward and medially

Question 17

medial rectus action

Answer 17

Rotates eyeball so that cornea looks medially

Question 18

lateral rectus action

Answer 18

Rotates eyeball so that cornea looks laterally

Question 19

Superior oblique action

Answer 19

Rotates eyeball so that cornea looks downward and lateral

Question 20

Inferior obliqu action

Answer 20

Rotates eyeball so that cornea looks upward and laterally

Question 21

sphincter pupillae of iris and Ciliary muscle nerve supply

Answer 21

Parasympathetic via oculomotor nerve

Question 22

Ciliary muscle function

Answer 22

Controls shape of lens; in accommodation, makes lens more globular

Question 23

Levator palpebrae superioris nerve supply

Answer 23

• Striated muscle oculomotor nerve,

- smooth muscle sympathetic

Question 24

Levator palpebrae superioris function

Answer 24

raises eyelid

Question 25

The lacrimal gland consists of a large orbital part and a small palpebral part, which are continuous with each other around the lateral edge of the aponeurosis of

Answer 25

the levator palpebrae superioris

Question 26

The lacrimal gland opens into the lateral part of the superior fornix of the conjunctiva

Answer 26

by 12 ducts
