chalazion lacrimal gland!?
Q. Does a chalazion surgery damage any of these glands important gland: - Meibomian gland. - Lacrimal gland. - Lacrimal duct.
Asked by Scott - Wed Apr 15 06:28:33 2009 - - 1 Answers - 0 Comments

A. occasionally it can damage the meibomian gland. the lacrimal gland is too far away and the lacrimal duct wouldn't be touched in the surgery as the surgery is concentrated on the eye lid margin.

Why does lacrimal secretion increase substantially when we are upset?
Q. I understand that lacrimal fluid flows from the lacrimal gland positioned on the lateral orbital region of the eye to the excretory lacrimal ducts which transmit tears across the eye surface. These tears (lacrimal fluids) then collect into medial little holes called the lacrimal puncta and then flow into the lacrimal canaliculus to the lacrimal sac and then drain into the nasolacrimal duct. So then, it seems that this flow of lacrimal secretion/fluid increases substantially in the lacrimal gland where it then oozes out to flow in the rest of its path. Am I right in assuming this? So, then, why does being upset/highly emotional increase lacrimal secretion in the lacrimal glands above the eyes?

A. We humans have the most highly developed forebrains of any creature on earth (except maybe dolphins) The result of this is we have emotions... not just primal instincts. We share fear, anger, jeoulosy, survival instinct and so on with our animal cousins, but we also have love, devotion, admiration, resentment, sorrow, and a whole host of complex emotions that are unique to homo sapiens. One of the most common physical side effects of strong emotion is crying. If this sounds completely alien to you then you have no soul.

Is it true that your lacrimal gland can be empty if you cry too much so that you will stop eventually?

How do our lacrimal glands produce tears when we cry emotionally?
Q. in our anatomy and physiology class, we discussed that there is still no scientific evidence why there are tears pouring when we are upset. im wondering why and how could our glands produce so much tears? i usually cry, like a lot. so yeah, im curious.
Asked by the damsel - Fri Jan 23 07:43:50 2009 - - 1 Answers - 0 Comments

A. Hmm, I've heard differently. Supposedly, when we cry, a certain chemical is released in the tears (salty taste) that helps alleviate the emotions in our brain. Therefore, if you're sad, and you cry, you're, in a way, crying out the sadness.

I understand why we tear when we yawn, but how to prevent it?
Q. I tear up when I yawn, I know how's its caused.. This is because the stretching of the facial muscles during yawning stimulates or irritates the nearby lacrimal gland(tear producing gland located near the upper outer area of the orbit) thus causing it to produce tears. But how do I prevent my eyes watering from yawning?

I have a lump under my eyelid, can you please help?
Q. I can't afford a doctor, but I think I might have come close to figuring out the problem for myself. After doing some research I have concluded that the lump comes from the Superior Lacrimal Gland. Its a small lump that has been there awhile (years). I went to an eye doctor a long time ago about it but he couldn't figure it out. He said after numbing my eye, he could pull the lump all the way diagnal across my eye ball only for it to sling back. I guess it's a ball of fatty tissue, but is it safe? It causes no pain, except itches very occasionaly. If you have any idea what this could be or even more info please let me know. If i have to I can get a picture.

Which one of the following glands secretes hormones without the use of duct?
Q. Likely answers: A. Sweat glands. B. Lacrimal glands. C. Pituitary glands. D. Salivary glands.
Asked by Pat. - Tue Nov 18 14:19:24 2008 - - 2 Answers - 0 Comments

A. i agree, it's the pituitary gland. it's an endocrine gland. (glands without ducts are called endocrine glands. since they don't have ducts, they secrete their products directly to the blood stream surrounding that gland.) sweat glands, lacrimal glands (for tears), and salivary glands all have ducts, so they're called exocrine glands.

A. 1. False. A typical human rib cage consists of 24 ribs, the sternum, costal cartilages, and the 12 thoracic vertebrae. 2. Three: Skeletal, smooth and cardiac. 3. nasopharynx (eustachian tube is in the ear, lacrimal glands are in the eye, larynx is in the throat, nasopharynx is the upper part of pharynx.) 4. bronchi (they branch out into bronchioles that end at the alveoli) 5. capillaries (you want a very thin layer of skin to contact blood for efficient oxygen/carbon dioxide exchange)

If there ws no sebum or lipid on our eyelashes, would our tears TOTALLY evaporate?
Q. In an earlier question I asked if the sticky substance on our eyelashes was sebum. The Wikipedia says that, "The glands of Zeis service the eyelash. These glands produce an oily substance that is issued through the excretory ducts of the sebaceous lobule into the middle portion of the hair follicle. Glands of Moll and Zeis secrete lipid that adds to the superficial layer of the tear film, retarding evaporation." So, does that mean that without the sebum and "lipid" on our eyelashes, our tears would evaporate?? RyanCaz answered with the following, "Yes, the sticky substance on eyelases is sebum, secreted mostly from the glands of Zeis. The Glands of Moll are more of a sweat gland.The wikipedia entry is somewhat true, but the Meibomian… [cont.]

Post-op LASIK Blurring for how long?
Q. Before, my eyes were both grade 20/350. I couldnt drive or watch movies or even read the blackboard without squinting even when seated up front in class. I had to use my glasses/contact lenses. So, i decided to have LASIK done. It cost me 26,500 Philippine pesos (U.S.$ 530) all in all, both eyes. This clinic used to charge over P40,000 ($800) for both eyes, but they had a Holiday promo. The more popular hospitals would charge P50,000 to 75,000 ($1000-1500) for both eyes. Despite the lowered price, my friend who also had his LASIK at the same clinic before the promo price said the whole procedure was the same. (Though his blurring cleared only 30 days after LASIK) The clinic didnt skimp on anything (Surgeon, Meds and Machine… [cont.]

A. Poor lubrication is definitely a common side effect of Lasik surgery. Whether your problem will subside or disappear entirely over time or not can't be predicted --- you will just have to wait and see. I still have lubrication problems a year after Lasik, so I think I'm stuck with it. It's actually not too bad; my problem with glare and light sensitivity is much more bothersome. Get some really good liquigel type lubricant drops and use them several times each day. I like Genteal drops a lot, also Refresh, and Bausch and Lomb Smooth is excellent for restoring the oils that the eyes need. Use a lubricant right before bedtime and if you get up during the night, use them again.

A. you got it right, it's not detailed but that's what you want,it's a nice comprehensive summery for a tricky structure. i just want to point one thing out (for the sake of accuracy) but i think u might already know it, you wrote that "pterygoid canal for autonomic fibers from CN 7". only the parasympathetic fibers come from the CN VII, the sympathetic fibers come from the internal carotid plexus (Postganglionic sympathetic fibers ascending from the superior cervical ganglion) that converge to form the deep petrosal nerve, then it joins greater petrosal nerve to form the nerve of the pterygoid canal. good luck
