what is the function of glottis?

The space between the vocal cords is called the glottis. As the vocal cords vibrate, the resulting vibration produces a "buzzing" quality to the speech, called voice or voicing.\n\nSounds production involving only the glottis is called glottal. English has a voiceless glottal fricative spelled "h". In many accents of English the glottal stop (made by pressing the folds together) is used as a variant allophone of the phoneme /t/ (and in some dialects, occasionally of /k/ and /p/); in some languages, this sound is a phoneme of its own.\n \nSkilled players of the Australian didgeridoo restrict their glottal opening in order to produce the full range of timbres available on the instrument. \n\n(glottis-the vocal apparatus of the larynx; the true vocal folds and the space between them where the voice tone is generated.)

"Some muscles attached to the external ear in humans seem vestigial in terms of evolution.  Some of us can wiggle our ears, some of us cannot.  In lower mammals, dogs for instance, these muscles allow exquisite control of the external ear for purposes of moving them to better able to detect where sounds originate.  In some aquatic animals, the little tab of skin in front of the ear canal, called the tragus, can be operated to act as a valve to open and close the ear canal.\n\nHowever, the earlobe itself has no known biological function."

Goblet cells are glandular simple columnar epithelial cells whose sole function is to secrete mucus.\n\nThe majority of the cell's cytoplasm is occupied by mucinogen granules, except at the bottom. Rough endoplasmic reticulum, mitochondria, the nucleus, and other organelles are concentrated in the basal portion. The apical plasma membrane projects microvilli to increase surface area for secretion.

vocal cords in humans are called larynx.\nDog and Cats both have 1 each vocal cords.\n(I think)

When it goes and touches the wind pipe the epiglottis closes the wind pipe preventing the fluid going inside the wind pipe.  The cough is the natural  and defensive phenomena which brings out the minute amounts  what is gone inside.

The primary function of the male reproductive system is reproduction, which includes the production of spermatozoa, the transportation of spermatozoa from the testes out of the male body, the secretion by glands, and the placement of spermatozoa in the female reproductive tract. Spermatozoa are produced in the testes then transported from the testes by a series of ducts which become gradually larger and connect with the urethra of the penis.  Various accessory glands in the male system secrete materials which together with the spermatozoa constitutes the semen. A secondary function of the male reproductive system is the production of the male hormones which are responsible for the secondary sex characteristics of the male animal.\n\nhttp://www.cvm.okstate.edu/instruction/mm_curr/histology/MR/himrp1.htm\n\nThe male reproductive system, like that of the female, consists of those organs whose function is to produce a new individual, i.e., to accomplish reproduction. This system consists of a pair of testes and a network of excretory ducts (epididymis, ductus deferens (vas deferens), and ejaculatory ducts), seminal vesicles, the \nprostate, the bulbourethral glands, and the penis. \n\nhttp://training.seer.cancer.gov/module_anatomy/unit12_2_repdt_male.html\n\nThe organs of the male reproductive system are specialized for the following functions:\n\nTo produce, maintain and transport sperm (the male reproductive cells) and protective fluid (semen) \nTo discharge sperm within the female reproductive tract \nTo produce and secrete male sex hormones \n\n\nhttp://www.cchs.net/health/health-info/docs/2300/2376.asp?index=9117

Myoelastic-aerodynamic Theory\nEarly voice researchers in the 1950's and 1960's explained vocal fold oscillation with the myoelastic-aerodynamic theory. According to these theories, Bernoulli forces (negative pressure) cause the vocal folds to be sucked together, creating a closed airspace below the glottis. Continued air pressure from the lungs builds up underneath the closed folds. Once this pressure becomes high enough, the folds are blown outward, thus opening the glottis and releasing a single 'puff' of air. \n\nThe lateral movement of the vocal folds continues until the natural elasticity of the tissue takes over, and the vocal folds move back to their original, closed position. Then, the cycle begins again. Each cycle produces a single small puff of air; the sound of the human voice is nothing more than tens or hundreds of these small puffs of air being released every second and filtered by the vocal tract. \n\nLet's further examine the myoelastic-aerodynamic theory. Myo- means muscle; the vocal folds, after all, are mostly comprised of muscle tissue. The -elastic suffix serves to remind us that the vocal fold is elastic and that we have active control over its elastic properties. Aerodynamic means that the theory deals with the motion of air and other gaseous fluids, and with the forces active on bodies in motion (such as the vocal folds) in relation to such fluids.

Drink some water, or some nice hot tea. Eat light. Maybe a bowl of soup. Anything to keep your vocal cords moist, and not cloggy. Stay away from chocolate and peanut butter too, they tend to coat your vocal cords like dairy products do. GOOD LUCK!:)

if you mean the glottis then you always activate both-you can't only activate one of them.

They tighten in the larynx to produce higher sounds, and loosen to produce lower sounds.

my sister had her tonsils taken out when she was 11. Even though she was young it never had any effect on her voice at all. I looked this up on the net....According to reference book “Encyclopedia and Dictionary of Medicine, Nursing and Allied Health,” the tonsils are lymphoid tissues that are often partially embedded in the mucous membranes. The tonsils’ primary function in this system is its vigilant prevention of pathogen invasions in the upper respiratory tract. This is made possible by the abundance of lymph nodes in its framework thus filtering out the circulating lymph of bacteria and any other foreign material that gain access to the body especially those that pass through the nose and the mouth. Your tonsils are not any where near your voice box. The Palatine tonsils at the back of the throat are located a fair distance from the larynx or voicebox. \n It may take awhile to heal after your get your tonsils out. My suggestion is: try drinking soda, like 7-up or any clear liquid with carbonated water.  It will make the healing work faster. The carbonated water helps clear the mouth and throat.

any forced expiratory effort (“strain”) against a pinced nose, whether at the nose and mouth or at the glottis; will help you for the hiccups\n\none more option is to drink water

I believe it's main purpose is to sooth a sore irritated throat.

Actually, I think we're thinking of this backwards.\n\nThe uvula is more likely to be an evolutionary remnant rather than a structure with a true purpose.  Early land animals probably had independent structures for breathing and eating (i.e. a distinct nasotracheal tube and a distinct pharyngoesophagus) as do modern ocean mammals like dolphins and whales.\n\nThe theory is that at some point (God know's why... and I'm sure He is the only one) the tubes crossed and coalesced into the nasopharyngeal cavity that humans now have.  The wall that once separated the tubes receded, the lower part becoming the epiglottis and the upper part becoming the soft palate and uvula.  \n\nThis also explains why the trachea is in front of the esophagus and the need for an epiglottis to even exist.  The soft palate and the posterior wall of the nasopharynx act as a barrier for food from going up the nose.  The uvula on the other hand literally just hung on for the ride.  ;)

If you mean the "Uvula"....The uvula, is a muscular flap of tissue that hangs down from the back of the mouth from from your soft palate. The soft palate is part of what separates the mouth (oral cavity) from the nose and the back of the throat (nasopharynx). The main purpose of the uvula is to close of the nasopharynx when you are swallowing or speaking. As far as I know it serves no other purpose.
