3 tunics of the eye and their contents:
|
Fibrous tunic
--cornea (transparent) --sclera (white)-Dense regular CT limbus is between Vascular tunic --choroid --cilliary body --iris Neural tunic --retina |
|
Identify the labels
|
A-retina
b-choroid c-sclera |
|
What is this? Identify the labels
|
Cornea of the eye
MN: EBSDEin "ebstein" A-epithelium-stratified sqamous B-bowman's membrane C-endothelial cells D-descemet's membrane |
|
How does the cornea get oxygen?
|
It is avascular, so it must receive nutrients from diffusion through the aqueous humor
|
|
Where is this? What is that hole?
|
Corneosclera junction : limbus
SChlemm's canal-drains aqueous humor |
|
What does the choroid of the eye contain?
|
vascular layer that includes capillaries and connective tissue, the innermost layer that separates it from the retina is the Brusch's membrane. It also contains melanocytes,
|
|
What is this?
identify the labels |
Limbus area again
A-conjunctiva b-sclera (covered in bulbar fascia) C-cilliary body d-cilliary processes |
|
What is this?
|
The iris, it contains melanocytes and muscle tissue
|
|
Name each layer 1-10
|
1: pigment epithelium
2: photoreceptors 3: outer limiting membrane 4: outer nuclear layer 5: outer plexiform layer 6: inner nuclear layer 7: inner plexiform layer 8: ganglion 9 optic nerve 10: inner limiting membrane |
|
What is this? What is the arrow pointing at?
|
Optic disk, central retinal artery
|
|
What is this?
|
ora serrata is the serrated junction between the retina and the ciliary body. This junction marks the transition from the simple non-photosensitive area of the retina to the complex, multi-layered photosensitive region. I
|
|
What is this?
|
Macula lutea/fovea centralis- only cones, no rods, best visual acuity in the eye
|
|
What is this?
|
Eye lid- tarsal glands secrete an oily substance, the arrow is pointing to an eye lash
|
|
Which two layers detach in retinal detachment?
|
The pigment epithelium (1) from the photoreceptor layer (2)
|
|
What is this?
|
Lacrimal gland,
similar to parotid gland, has tubular alveolar serous cells that secrete the tears, located in the upper lateral region of the orbit |
|
Identify the labels of what kind of papillae is found at each point.
|
A-foliate
b-fungiform c-filiform d-vallate e-foramen cecum and circus terminales |
|
Name each structure:
|
A-fungiform
B-filiform C-Vallate D-foliate E-von ebner gland |
|
Answer each with the letter that matches the characteristic:
1-has no taste buds 2-is present on the entire surface of the tongue 3-covered in strat squam epithelium 4-non keratinized strat squam epith 5-located on the posterior and lateral border of the tongue 6has von ebner glands opening on it |
1,2,3 =B
4=A 5=D 6=C |
|
What does a von Ebner gland secrete?
|
serous solution that cleans out the groove so new things can be tasted
|
|
What is the structure of a taste bud?
|
oval in shape, with spindle cells inside of it, that have microvilli that project out through a taste pore and into the surrounding environments
|
|
Where are taste receptors located?
|
on the microvili of the taste bud cells
|
|
What is this? Identify the labeled structures and their function:
|
A-olfactory cells-bipolar neurons, allow the sense of smell
b=sustentacular cells-tall columnar cells with a microvilli border, nucelli are found superficial to the nuclei of the olfactory cells c-basal cells-lie against the basal lamina, replace the basal and sustentacular cells D- Bowman's glands-secretes odor binding protein |
|
Which concha has olfactory epithelium?
|
Only the superior concha.
|
|
Identify the labels:
|
A-sustentacular cells
b-olfactory cells c-basal cells d-bowman's glands |
