Roll My Eyes
What's Inside?
There's More Inside?
Miscell-EYE-neous
100
This is part of the lacrimal apparatus that helps to produce tears.
Lacrimal gland
100
What is this muscle that helps to elevate the eye and is innervated by the oculomotor nerve?
Superior rectus
100
This is the "white of the eye" and is formed from dense collagenous connective tissue.
Sclera
100
This is the anterior transparent region that admits light and covers the pupil/iris.
Cornea
100
This can be bent to focus passing light.
Lens
200
This is part of the lacrimal apparatus that collects tears.
Lacrimal sac
200
What is this muscle that helps to depress the eye and is innervated by the oculomotor nerve?
Inferior rectus
200
This structure controls the diameter of the pupil.
Iris
200
This is an opening which allows light to pass into the eye.
Pupil
200
This is the transparent mucus membrane that covers the inner surface of the eyelid and anterior surface of the eye.
Conjunctiva
300
This is 2 small channels in the lacrimal apparatus that receives tears and delivers them for storage.
Lacrimal canals
300
DAILY DOUBLE! -- What is this muscle that moves the eye laterally and what nerve innervates it?
Lateral rectus and Cranial Nerve 6 (Abducens)
300
This is highly vascular, deeply pigmented, and located behind the retina. It helps to absorb light and provide nutrients to the retina
Choroid
300
This is a thickened muscular ring around the lens that helps to shape the lens via the suspensory ligaments.
Ciliary body
300
DAILY DOUBLE! -- Which cranial nerve is contained in the neural layer of the retina, helps to innervate the eye, and joins the _________ which creates a blind spot and allows blood vessels to enter/exit the eye. (Needs 2 answers)
Optic Nerve (cranial nerve II)
Optic disc
400
This is part of the lacrimal apparatus that receives tears and drains it into the inferior meatus of the nasal cavity.
Nasolacrimal duct
400
What is this muscle that helps to elevate and turn the eye laterally and is innervated by the oculomotor nerve?
Inferior oblique
400
This is a cup shaped extension of the diencephalon that contains a pigmented and neural layer.
Retina
400
This is in the neural layer of the retina which produces finely detailed images.
Fovea centralis
400
What is this muscle that helps to move the eye medially and what nerve innervates it? (Needs 2 answers) is innervated by the oculomotor nerve?
Medial rectus
Oculomotor nerve (Cranial nerve III)
500
This is 2 small openings in the lacrimal apparatus that collects tears and helps with drainage to other parts in the apparatus.
Lacrimal punctum
500
What is this muscle that helps to depress and turn the eye laterally and what is the nerve that innervates it?
Superior oblique and Cranial Nerve 4 (Trochlear)
500
Which layer of the retina absorbs light and prevents it from scattering and also stores Vitamin A whereas which layer generates chemical or electrical signals in response to light stimulation? (Need to name 2 layers)
Pigmented layer (absorbs light)
Neural layer (generates chemical/electrical signals)
500
Which humor is a clear fluid that is secreted by the ciliary body and flows from the pupil to the anterior chamber whereas this humor is transparent jelly that lies behind the lens and holds the retina in place.
Aqueous humor (clear fluid)
Vitreous humor (transparent jelly)
500
Which photoreceptor (located in the neural layer of the retina) is responsible for night vision whereas this photoreceptor (also located in the neural layer of the retina) is responsible for color vision.
Rods (night vision)
Cones (color vision)
