What does the cilliary muscles do?
The Cillary Muscles are basically muscles inside your eye that stretch and change shape to get the perfect image to your brain
Is shampoo bad for anal?
In a word, yes. What would happen if you shampooed your hair over and over? You would ruin it since all the natural oils would be taken out. Now imagine your anus (or their anus) which is very sensitive mucal membranes becoming really dried out. The same for your or their penis. Both of you might end up becoming really sore and in the worst event ending up in the emergency room. "You used what where?" Far better to use vaseline or some hand cream or one of those special products on the market specially for this. In any case, try a little at first to make sure it doesn't sting, burn etc.
What functions do the extrinsic muscles of the eye perform?
It's the string like things on the back of the eye next to the optic nerve, it allows the eye to move around.Human eye have ciliary muscles not eye muscles,which holds the eye lens in position.these muscles controls the focal length of eye lens.They change the shape of the lens. (Novanet)
What percent of drugs is absorbed into the body and what percent of the drug is excreted out of the body?
Absorption will depend on the drug itself and the method of injestion, IV, IM, and SC injection will usually be absorbed at 100%, smoking, nasal or anal absorption is usually much higher eating the drug, which is the least effective due to stomach acids and enzymes. This is why users will prefer injecting, smoking or snorting a drug in order to reduce their usage and save money. The method of injestion also affects the speed of absorption, which is in this order: fastest: intra-venus injection, then Smoking, IM injection, SC injection, insufflation, anal injestion, mucal absorption(holding it in the mouth) and then, last and slowest: oral. As for excretion, as far as I know, all drugs are excreted at 100%, given enough time, marijuana can take months to leave the system, cocain takes mere hours, but all drugs are excreted completely, however, if more drug is taken before it has finnished excreting, then the body may end up with very large amounts building up, and unless the user stops, the amount will keep growing. Also note, there is no known basis for the spinal fluid theory propagated about every drug known to man at some point in time.
What lens are need to correct hyperopia?
Read lots of books. Spend hours focusing on close things. Learn how to knit to or something. If ur eyes hurt that means your cillary muscles are working hard to accomodate. Eventually your eye will elongate to compensate. Unless your over 25. Everyone is born with Hyperopia. We're built that was so that our eyes adjust to the world around us. Most people tho end up over adjusting because of school word and lack of outdoor abilities. Hyperopes are rare these days. That means you were probably born with a high degree of hyperopia and modern society life wasnt enough to create a myopic shift. If your still young, try spending hours doing close work. Dont over do it tho.. u may end up nearsighted lol.
What is a lung infection?
A lung infection can be a difficult thing to diagnose and has many contributing factors. The most common way to get an infection is from a common virus. A cold or virus or a bout of bronchitis that keeps coming back can leave a mucal build up in your lungs that can become infected, especially in those without the ability to naturally cough up the phlem themselves. That's why it is very important to see a doctor whenever a cold or virus lingers or keeps coming back, because left alone it can turn into a serious health problem. Even something as simple as a sinus infection left unattended can be a serious thing , it can spread over several weeks into ear infections , throat infection due to post nasal drip & can easily lead to chronic upper respritory infections . Most common symptoms of a bacterial infection are; sinus pain & pressure headache ear pain swollen glands cold/clammy hands& feet jaw / neck pain difficulty sleeping difficulty thinking breathing discomfort post nasal drip lethargy weakness burning feeling around neck / ears facial swelling/tenderness coughing / sneezing congestion tightness in chest some may even get a stomach ache or have digestive problems due to swallowing lage amounts of infected mucus. Some people may have some or all these symptoms.That's why it is important to get to a doctor and get diagnosed before the infection gets serious. Doctors will generally prescribe antibiotics for a week or longer & a combination of nasal sprays, allergy medications , and possibly a steroid medication for nasal or lung inflammation.
Why it hurts when i touch the glans of my penis?
Yes the exposed glans of an intact penis can be very sensitive especially when it has not been exposed on a regular basis.however you my be confusing pain with senitivity. It is normal for the glans to be sensitive because the glans is highly enervated and protected by the foreskin. it will become less sensitive and easier to deal with over time. Both the glans and the iner mucal surface of the prepuce (foreskin) are very sensitive parts of the penis and can a first be so sensitive that hey may be difficult to handle.But how do you distinguish between hurt and sensitiveness ?Its easier to masturbate with the foreskin over the glans but does hurt (not really but the sensation is just too weird) when you touch the glans directly. How to enjoy the weird sensation ? Is there any kind of reading material available on the same ?I have this problem, I am uncut and touching my glans with my bare hands is uncomfortable and can be painful if I do it a lot, luckily the tongue and lips are soft enough that it causes no pain or discomfort at all, but if you don't have a willing partner or just can't bend that way, I find a good lubricant usually helps, Ansell Lifestyles 'silky smooth' is the best that I have found. (But see below.)I have exactly the same problem Soreness/Sensitivity of the glans, I have been told it's very normal especially as I have very very rarely pulled my foreskin back I have been advised to roll the foreskin back and hold the glans between finger and thumb under water, to get the head used to being touched. I am going to try this over the next few weeks to see how I get on. I have always had this problem but just lived with it.[By the way, it's worth noting that the word 'glans' is singular, not plural.]The glans is an internal organ designed to be exposed on each thrust within a vagina during sexual intercourse. It is kept supple, protected and naturally lubricated by the foreskin when the penis is flaccid. The foreskin is innervated with multiple nerves which activate when masturbation or sexual penetration occurs.After ejaculation takes place - either through masturbation or sexual intercourse - the glans is intensely sensitive. Any touch by clothing or fingers on the exposed glans is similar to accidentally knocking our humerus (funny bone). But the sensation is clouded with such an intense mix of sensitivity and relative pain, we recoil from any touch. This is nature's way of 'correcting' us if we leave our foreskin still retracted after ejaculation.Males circumcised as infants, or at any time before puberty, can never know the pleasure of owning a foreskin. Grown, circumcised, adult males will say, "I'm just fine as I am," never knowing what they missed!So, yes... it's normal and wonderful that the glans of an intact penis is so marvelously sensitive - even if you touch it when erect. All it is telling you is that it's working properly!When you are still young and your penis is left intact it is normal for you to find that the glans of the penis is extremely sensitive, to the point where this may be confused with pain. However in time the sensation will become bearable and give you the pleasure that circumcised penises will never be able to give. Just be a little patient. Many circumcised males, young and old, find they need artificial lubrication to masturbate satisfactorily; whereas intact males don't. Happily, the inner foreskin is self-lubricating. It's all part of nature's perfect design.intact men's heads are very sensitive when they circumcise you they take away all the sensitivity that why its better to have foreskinBe proud to be intact first off, but to answer your question, your penis is more sensitive because the foreskin is protecting the head of your penis from minor abrasions that occur in your underwear from day to day. If it is so uncomfortable or painful, speak to your doctor, maybe he can shed some light on the subject!If you are worried about the sensitivity of your penis or it's giving you pain, please consult your doctor for more information and helpAt first the head of the intact penis is very sensitive and you may well confuse it with pain However given a little time and adequate lubrication when handling it you will soon get used to it.play with it. touch it, but lightly. it will toughen it up a bit. if you have a partner, encourage them to use their tongue. a bit of masturbation using a lubricant will help get it under control as well and it feels good too.
Parts and functions of the eyes?
ConjunctivaIs a thin protective covering of epithelial cells. It protects the cornea against damage by friction (tears from the tear glands help this process by lubricating the surface of the conjunctiva)CorneaIs the transparent, curved front of the eye which helps to converge the light rays which enter the eyeScleraIs an opaque, fibrous, protective outer structure. It is soft connective tissue, and the spherical shape of the eye is maintained by the pressure of the liquid inside. It provides attachment surfaces for eye musclesChoroidHas a network of blood vessels to supply nutrients to the cells and remove waste products. It is pigmented that makes the retina appear black, thus preventing reflection of light within the eyeball.Ciliary bodyHas suspensory ligaments that hold the lens in place. It secretes the aqueous humour, and contains ciliary muscles that enable the lens to change shape, during accommodation (focusing on near and distant objects)IrisIs a pigmented muscular structure consisting of an inner ring of circular muscle and an outer layer of radial muscle. Its function is to help control the amount of light entering the eye so that:- too much light does not enter the eye which would damage the retina- enough light enters to allow a person to seePupilIs a hole in the middle of the iris where light is allowed to continue its passage. In bright light it is constricted and in dim light it is dilatedLensIs a transparent, flexible, curved structure. Its function is to focus incoming light rays onto the retina using its refractive propertiesRetinaIs a layer of sensory neurones, the key structures being photoreceptors (rod and cone cells) which respond to light. Contains relay neurons and sensory neurons that pass impulses along the optic nerve to the part of the brain that controls visionFovea (yellow spot)A part of the retina that is directly opposite the pupil and contains only cone cells. It is responsible for good visual acuity (good resolution)Blind spotIs where the bundle of sensory fibres form the optic nerve; it contains no light-sensitive receptorsVitreous humourIs a transparent, jelly-like mass located behind the lens. It acts as a 'suspension' for the lens so that the delicate lens is not damaged. It helps to maintain the shape of the posterior chamber of the eyeballAqueous humourHelps to maintain the shape of the anterior chamber of the eyeball
