The tympanic membrane is the formal name of the eardrum. Incoming sound waves are channeled into the ear canal and come into contact with this membrane, causing it to vibrate. These vibrations are transmitted to the bones of the middle ear, called the auditory ossicles. These bones are the malleus, incum, and stapes, also known as the hammer, anvil, and stirrup. These bones transmit the vibrations through to the oval window of the cochlea, which houses the receptor cells that will transduce the physical energy into electrical energy within the nervous system. Thus, the correct order is, tympanic membrane, auditory ossicles, cochlea.

Visual acuity is best for light falling upon the fovea. The fovea is an area of the retina corresponding to the center of our visual field. In other words, any object we focus our eyes on will be reflecting light that is striking our fovea. This region contains the highest concentration of cones, which are more sensitive than rods, and produce more detailed visual information.

Visual acuity diminishes towards the periphery of the retina and visual field, as more rods and fewer cones are responsible for processing light information in these regions.

The blind spot receives no visual information whatsoever, as no photoreceptors are present here. Instead, the optic nerve interrupts the retina and exits the back of the eye in this location.

The vestibular sense is that which controls our sense of balance and orientation. It is produced as a result of movement sensitive receptor cells in fluid filled chambers within the inner ear called the semi-circular canals. Changes in the body's orientation in space cause this fluid to move, as it seeks to find its level under the affect of gravity. This movement is detected by the hair-like receptor cells within the semi-circular canals, which send signals to the brain. 

As a result of this sense, we are aware of our balance, and are able to stand upright and move without falling over.

Pain receptors in the skin help keep us away from injurious stimuli, and the olfactory sense helps us to avoid noxious stimuli. 

Hormones and physical factors help prevent us from overeating, and the pupil and pain receptors in the eye help keep us from staring directly into the sun- that and hopefully common sense!

The kinesthetic sense is the awareness of the body's position in space, and of the movements of its various limbs. This sense is generated by receptors within muscles and joints that respond to the body's motion. This sense explains how you can close your eyes, but still know how your body is positioned, and accurately perform motions without needing sight of your limbs. Individuals suffering from disruption of their kinesthetic sense must use their vision to guide body movements, for instance by watching their feet and legs as they walk, or following a hand or arm as it moves towards an object.

The semicircular canals of the inner ear, and the hair-like receptors within them, contribute to the vestibular sense. This is the body's sense of balance and orientation, and it is generated by responses to movements in the fluid within the semicircular canals. This is distinct from the kinesthetic sense, but both contribute to somatosensation. 

Skin receptors responding to pain, pressure, vibration, and temperature also contribute to somatosensation. These do not contribute to the kinesthetic sense however.

Transduction is the conversion of one form of energy to another. In audition, the sense of hearing, transduction involves the conversion of physical energy carried in sound waves and vibrations into electrical energy within the nervous system. This occurs in the cochlea. Within the cochlea are hair-like receptors that respond to movements in the fluid that surrounds them, which in turn moves as a result of the vibrations which are transmitted to it by the auditory ossicles and the eardrum.

The tympanic membrane is the eardrum. This membrane transmits vibrations further into the ear, by moving the auditory ossicles.

The auditory ossicles are the bones within the ear. These sensitive bones transmit vibrations to the cochlea from the eardrum.

The stapes is the third of the auditory ossicles. It causes the oval window of the cochlea to vibrate, thereby transmitting vibrations to the fluid filled chamber within.

The pinna is the outside of the ear (the part we see sticking out the sides of our heads and that we think of when we hear the word 'ear'). It helps to capture sound and channel it inward to the eardrum, rather like a satellite dish.

Subliminal messaging can produce some minor changes in behavior in laboratory settings; however, research has indicated that these effects have been very minor. The general consensus is that it is unable to influence complex human behaviors. As a result, subliminal advertising is no longer commonly explored by marketers, nor feared by the public.

It has been observed that regardless of the environment subliminal messaging is unable to manipulate complex behaviors without the subject's awareness; therefore, it does not require regulation by law.

Olfactory loss constitutes a loss of the sense of smell. Aside from detecting airborne odors, this sense is also responsible for much of our ability to experience the flavors of foods and beverages. As a result, the loss of this sense would be a terrible setback to someone who's profession relied upon a sensitive palate, such as a food critic or wine taster.

Cortical blindness is a form of blindness, and would not be a severe hindrance to such an individual. Likewise, an astigmatism is a defect in vision caused by an imperfection in the shape of the eye, and neither this nor a loss in hearing ability brought about by damage to the auditory ossicles—the inner ear bones—would result in as significant a setback to a food critic or wine taster.

Subliminal perceptions are those that involve stimuli occurring too weakly or quickly to be recognized consciously. When these were first discovered, there was much excitement and concern over the potential applications of non-conscious perceptions to the field of advertising. Although many subliminal ads were created and tested, it has since become apparent that they are largely ineffective. Although subliminal perceptions can alter behavior in laboratory settings, they fail to have a significant impact on human behavior—especially in the area of complex decision making that interested marketers. Subliminal perceptions also fail to produce significant changes in emotions, and—if anything—have a weak or negligible effect at best.

Astigmatism is an imperfection in the curvature of the eye, which prevents light from focusing correctly on the retina. This imperfection can be found in either the cornea or the lens, and is sometimes resolvable with corrective lenses.

It is not caused by an elongated eyeball. Damage to the nervous system is also not responsible for astigmatism. Likewise, damage to the retina and faults in the brain are not to blame for astigmatism.

"Conduction deafness" is the term for deafness caused by damage to the eardrum or ossicles. It is distinct from nerve deafness, which is caused by damage to the auditory cortex or the apparatus of the inner ear. This form of deafness usually results in uniform hearing loss over all frequencies. This leads to sounds seeming quieter than they actually are.

Neither "ossicle deafness" nor "tympanic deafness" are correct terms for forms of deafness.
