what is the function of the lacrimal apparatus
Tear production and drainage
Protects the eye from excess light
Helps in eye movement
Protects the eye from minute dust particles
Which of the following is not part of the lacrimal apparatus
lacrimal glands
puncta
nasolacrimal duct
Conjunctiva
Our tears form a nutritive layer at the front of the eye
True
False
Nutritive Layer is formed by
Iris, choroid & Ciliary Body
Sclera & Cornea
Pigmented Layer
Neuronal layer
Sensory layer is made up of
Neuronal layer
Pigmented layer
Both
The conjunctiva is a thick , transparent mucous membrane which lines the outer surface of eyelids•
True
False
Which of following is not correct about Cornea
Cornea is transparent part of eye which allows light to enter the eye.
Continuous with the Choroid
Outer surface epithelium protects from abrasions
Inner surface epithelium, contains sodium pumps that help maintain clarity of cornea
Smooth white part of the eyeball is called as
Choroid
Cornea
Sclera
Iris
The middle vascular layer/ nutritive tunic has
choroid,
ciliary body
Iris
All
------lies between the sclera and the retina.
Iris
Choroid
Pupil
Conjunctiva
The choroid along with ciliary body and the iris form the
Uveal tract
Trabecular tract
Vitreous tract
Aqueous Tract
Contraction of ciliary muscles changes shape of lens
True
False
The colorful part of the eye is--
Iris
Ciliary body
Choroid
Retina
Which Structure divide aqueous chamber into anterior & posterior chambers.
Iris
Ciliary body
Pupil
Lens
The black circular opening in the center of the iris is known as
Cornea
Pupil
Iris
Conjunctiva
The pupil dilates when there is no light and constricts when light shines
True
False
The lens' job is to focus light rays on the back of the eyeball - a part called
Retina.
Choroid
Iris
Optic nerve
The Cornea takes the light , the eye receives and changes it into nerve signals
True
False
Choose the right path of Physiology of Vision
Cornea >> Aqueous Humor>>Pupil>>Lens>>Vitreous humor>>Retina>> Brain (cerebral cortex)
Cornea >> Pupil >>Aqueous Humor >> Vitreous Humor >> lens>>Retina>> Brain (cerebral cortex)
Anterior chamber of Aqueous Humor is the present between
the iris and the cornea
the iris and the lens
Filled with a clear watery fluid called the
aqueous humor
Vitreous humor
Tear
Through the trabecular meshwork, aqueous humor drains into
Blood stream
Uveoscleral outflow
Trabecular outflow
The functions of the aqueous humor is to
Maintain the intraocular pressure
Provide nutrition
Carry away waste products
All of the above
The functions of the vitreous humor include
Maintains shape of eyeball
Maintains intraocular tension & Nutritive function
Maintains intraocular tension
All
Vitreous humor present between the back of the lens and the surface of the retina.
True
False
