What are facts about the human body mouth?
there are 32 teeth in the average human body mouth.The upper jaw, that is part of the skullThe lower jaw, connected with the upper jaw and with ability to move up-down and from side to side
What is a specific body part that starts with a m?
Maleus; an ossicle in the middle ear (also called hammer)
What body system is the human jaw in?
The Mandible is your jaw, so it is associated with the Skeletal System, and the Digestive system.
What are the four parts of the human mouth?
There are three main parts of the human jaw. It is the chin, the mandible and the maxilla that all come together to form what is the lower half of our jaw.
How does does your ear hear sound?
Your ear may be considered to have three major parts, the external ear, the middle ear, and the innerear.The external ear comprises the parts that are exposed to the outside air, up to the ear drum. Attached to the innerpart of the eardrum are three tiny bones (the smallest bones in your body - grain sized.), and these in turn connect to an oval window, which is one of the boundaries of the inner ear. The inner ear is a tapering tube, arranged compactly as a spiral, and with a membrane dividing the tube into two lengthwise. Arranged along this dividing membrane, are numerous sensory hairs, each connected to its hair cell, and these to our auditory nerves.The ear drum vibrates in response to a sound, and this moves the series of three middle ear bones. Their arrangement helps the ear to deal with the huge range of sounds we encounter. The third of these is the stapes, which in turn vibrates the oval window, and passes the sound wave (now a vibration) to the fluid-filled cochlea. The vibrations in the cochlea, in turn activate the many thousands of hair cells (grouped according to frequency), and these send an electrical signal to the brain for interpretation.[Mammals have a 3-bone middle ear, and a 1-bone jaw. Earlier species in evolution have a 2-bone middle ear, and a 2-bone jaw.] The middle ear is ventilated to the atmosphere via your Eustachian tube, and when this becomes blocked by an infection, (or by rapid change in altitude e.g. air travel), we experience pain due to the ear drum being pressurized.[Located in the general vicinity of your ear are your balance organs, but these are not part of the hearing process. Birds have a magnificent 3-axis set of balance tubes, land animals have a good set, and fish have rather inferior set of balance tubes. [It doesn't matter so much if a fish falls over!]]
My ear hurts and it hurts my ear to chew food. do I have and ear infection or is it something else?
Depending on what you're eating, It may not be the ear at all, it might be the jaw. There is a bone that runs from the middle of the ear to the jaw and even though you don't feel anything around your jaw, it may be the reason your ear hurts. It might help if you had a doctor check it out though.

Hard lump between ear and jaw line hurts when touch swollen and red by the ear what could it be?
hard lump between jaw and ear what is it and how can it be cured?
Why snake can eat bigger animal?
because its jaw can unhinge and its jaw is not rigidly connected and it is Meryl connected by ligaments
Does swimmers ear affect your jaw?
Yes if its causing enough pain that moving your jaw is uncomfortable
How do you spell the human jaw?
The human jaw consists of two parts, one fixed and one movable. The fixed jaw is the maxilla (upper jaw) and the movable lower jaw is the mandible.
Why you cannot speak or hear properly when you yawn?
You can't speak properly because you are inhaling and then exhaling one right after another while your brain is forcing your jaw to drop. You can't hear correctly during a yawn because your brain is making your jaw drop as said before to equalize pressure in the middle ear. While this is happening there is a mild vacuum and pressure in the middle ear, as if you were in an airplane about to land.
Where is your jaw line?
the bone connected to your chin
What are all the human body parts that have nine letters?
eye, ear, lip, gum, jaw, arm, rib, hip, leg, and toe
What happens in different parts of the ear?
The three general sections of the ear are the outer (focusing), middle (converting) and inner ear (translating vibrations into nerve impulses).The Outer EarThis consists of the Pinna - the external bit you see, and the ear canal which terminates at the Ear Drum, a thin membrane. Also called the tympanic membrane.The Middle earThe middle ear contains three small bones, the smallest in the human body, Hammer (Malleus); Anvil (Incus); and the Stirrup (Stapedius).The Hammer and the incus are connected together in such a way that the efficiency of the sound transmission path may be varied depending on their relative position. You can hear over a range of about 120dB (decibels) and this is a range of 1012 to 1. *In addition as an accessory, here are located your balance organs.The middle ear connects to your mouth via theEustachian Tube, and this is responsible for balancing the air pressure across the Ear Drum. This is the one that causes trouble sometimes when in an airplane, or when you have a cold.The Inner EarThe inner ear is connected by the tiny Oval window to the Stirrup. The inner ear is called the Cochlea, as it resembles a snail shell curled up and is fluid filled. If it were straightened, it would be found to have a dividing membrane down the length of it, and on one side of it are thousands of hair cells, each group of which respond to sounds of different frequencies. Connecting to this fluid filled volume is also the round window, which helps balance out the pressure.The tiny hair cells are connected to the auditory nerve which goes to the brain, and when the hair cell is moved, its base creates an electrical signal which our brain interprets as sound, each of several thousand frequencies with its own amplitude.By comparison, if humans were able to judge weight over a similar range, they could distinguish any weight from one milligram right up to 1000 tonnes!One of the distinguishing characteristics of mammals is three middle ear bones, and one movable jaw bone. Reptiles have a two-part jaw bone, and only two middle ear bones.
Why can you move your lower jaw and not upper jaw?
Because your upper jaw is part of your skull which is connected to your spine and your lower jaw is connected to your upper jaw by a hinge type joint that allows you to move your lower jaw so that we can eat. So therefore we cannot move our upper jaw because that would require moving our head which would move our lower jaw too.
