Jaw : Parts of the body

                                                 A to Z 2019

Cambridge dictionary describes Jaw as the lower part of the face that moves when the 

mouth is open and shut.

The lower jaw is called mandible and fixed upper jaw is called maxilla. The joint where 

the mandible meets the skull is the temporomandibular joint. Jaws function by moving in 

opposition to each other and are used for biting, chewing, and the handling of food.

Wikipedia :  Jaw is a structure at the entrance of the mouth, typically used for grasping 
and manipulating food. 

Jaws function by moving in opposition to each other and are used for biting, chewing, 

and the handling of food.

The upper jaw is firmly attached to the nasal bones at the bridge of the nose. The arched 

lower part of the maxilla contains the upper teeth. Inside the body of the bone is the 

large maxillary sinus.

In the human fetus and infant both the upper and lower jaws have two halves; these fuse 

at the midline a few months after birth. 

The mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the 

human face. It forms the lower jaw and holds the lower teeth in place.

Jaw popping can be a painful sensation that's caused by dysfunction of the 

temporomandibular joints (TMJ). These joints connect the jawbone to the skull, with one 

joint on each side. ... When the joint doesn't work properly, popping can occur. The term 

TMJ is used both to refer to the joint and to the disorder.

Jaw problems include Fractures, Dislocations, Temporomandibular joint dysfuntion, 
Osteonecrosis and cancers. Treatment of jaw problems depends on the cause.
                                               Care of the Jaw

Becoming more aware of tension-related habits — clenching your jaw, grinding your teeth 

or chewing pencils — will help you reduce their frequency. The following tips may help 

you reduce symptoms of TMJ disorders

Avoid over-use of Jaw muscles : Eat soft foods. Cut food into small pieces. Steer clear of 

sticky or chewy food. Avoid chewing gum.

Stretching and massaging : The doctor, dentist or physical therapist may show  how to do 

exercises that stretch and strengthen the jaw muscles and how to massage the muscles. 

Heat or cold : Applying warm, moist heat or ice to the side of your face may help 

alleviate pain.

                                                          Sporting Arena
Athletes can suffer jaw injuries during sports  even with all the right equipment and 
skill. A study showed that nearly half of elite field hockey players will suffer mouth, 
tooth, or jaw injuries. Any time one plays a sport,  be mindful of mouth and jaw and do 
what one can to prevent injuries. Volleyball, soccer, basketball, football, martial arts, 
and many other activities can put  jaw at risk.

Jaws is a novel by Peter Benchley in 1974. A movie by the same name was made in 
1975. Jaws became the highest-grossing movie in history up to that point, becoming a 
watershed film in motion picture history. Three sequels followed the film.
       Readers, have you read this novel? Did you enjoy the novel or the movie?

Stones lay scattered everywhere; on the road, pavement and the kerb. Were all stones 

gathered in this place for a school reunion?, a soliloquy from John. He hunched as his 

school satchel bore the weight of his wisdom. His head turned in the direction of the 

noises heard in the distant. He picked up a stone and made a dash. The uniformed 

garrison were clashing with the hoi polloi. A commoner was punched in the jaw. This 

made John's jaws drop. He had never seen such a commotion before. John went further 

towards the epic center of the action. A stone came flying from nowhere . John ducked it 

in the nick of time. He has escaped from the jaws of death. His legs beat a hasty retreat.

  2. I clench my teeth and do have jaw ache problem. But the clenching of teeth seems to be related to some kind of problem with the digestion. It is believed that if we have some digestive problem because of infections of intestine there is a tendency to clench the jaw. And as far as the movie jaws is concerned I have watched it two or three times.

  3. I am not aware of the relation of Jaw clenching to infections of intestines. Let me check with my doctor. Thanks Jai .

  4. I'd never given my jaws much thought before reading this. I've now got that creepy music from the movie running through my mind!

    1. One has to pay attention to the jaw as food started to break down in the mouth.
      Thanks Keith.

  5. We should take care of our jaws as unhealthy jaws can lead to many problems.

  6. I had never even given Jaws this much of a thought. But your post is a harsh reminder of how much we ignore or abuse our body parts. Another enlightening post.

    1. Thanks Sonia C. we all ignore our body parts.

  7. Jaws fascinate me not the movie though.

  8. Yes, Jai is right. My old flatmate in Noida also used to do this while sleeping. Repeatedly clenching her jaw and grinding her teeth. I've also heard that it's related with some kind of intestinal infection. Not sure though.

    1. I enquired with a medico friends of mine and this is called Bruxism . Thanks Chick K for reading and commenting.

  9. I have become much more aware of jaw clenching so I try to avoid that. Also, I'm not chewing as many pencils as I used to. But eating nothing but soft foods??? I don't think that I can go quite that far!!!

    1. Thanks Alice G for visiting my blog. Could you please leave a link to your blog so that I can visit?

  10. Nice informative post which shows how much we neglect our body parts. The abuse they undergo daily is tremendous

  11. Insightful post. I did not know about TMJ disorder. I haven't seen jaw movie - will keep in the watch list.
    Trivia at the end - I liked the use of phrases like jaw drop, jaws of death! :)
