A medical thermometer or clinical thermometer is a device used for measuring the body temperature of a human or other animal. The tip of the thermometer is inserted into the mouth under the tongue (oral or sub-lingual temperature), under the armpit (axillary temperature), into the rectum via the anus (rectal temperature), into the ear (tympanic temperature), or on the forehead (temporal ...
Video showing how sounds make their way from the source to the brain. Hearing, or auditory perception, is the ability to perceive sounds through an organ, such as an ear, by detecting vibrations as periodic changes in the pressure of a surrounding medium. [1]
The temporal theory of hearing, also called frequency theory or timing theory, states that human perception of sound depends on temporal patterns with which neurons respond to sound in the cochlea. Therefore, in this theory, the pitch of a pure tone is determined by the period of neuron firing patterns—either of single neurons, or groups as ...
the tympanic duct or scala tympani (containing perilymph), which lies inferior to the cochlear duct and terminates at the round window; the cochlear duct or scala media (containing endolymph) a region of high potassium ion concentration that the stereocilia of the hair cells project into
When the stapes presses on the oval window, it causes the perilymph, the liquid of the inner ear to move. The middle ear thus serves to convert the energy from sound pressure waves to a force upon the perilymph of the inner ear. The oval window has only approximately 1/18 the area of the tympanic membrane and thus produces a higher pressure ...
This bony part is known as the auditory bulla and is formed by the tympanic part of the temporal bone. The ear canal ends at the external surface of the eardrum, while the surrounding skin contains ceruminous and sebaceous glands that produce protective earwax . [ 3 ]
For example, in a scenario where the actual temperature is 10 degrees but the "feels like" temperature is -5 degrees, what that really means is that the wind chill is making it feel as if the air ...
BA41(red) and BA42(green) are auditory cortex. BA22(yellow) is Brodmann area 22, HF(blue) is hippocampal formation and pSTG is posterior part of superior temporal gyrus. The auditory cortex is the part of the temporal lobe that processes auditory information in humans and many other vertebrates.
