of Inner Ear The inner ear is the essential part of the organ of hearing‚ receiving the ultimate distribution of the auditory nerve. It also called the labyrinth. Inner ear consists of two parts: the osseous labyrinth‚ a series of cavities within the petrous part of the temporal bone‚ and the membranous labyrinth‚ a series of communicating membranous sacs and ducts‚ contained within the bony cavities. The osseous (or bony) labyrinth: Bony labyrinth is the rigid outer wall of the inner ear

Anatomy and Functions of the Middle Ear The middle ear contains many important parts that necessary for hearing sounds. The middle ear consists of the structures enclosed in a space right behind the eardrum. They are the tympanic membrane or eardrum. The tympanic membrane is a thin membrane shaped like a drum that separates the outer ear from the middle ear. Next is a chain of three ossicles‚ or very small bones. The chain begins with the malleus‚ which is connected to the center of the tympanic

Evolution of the craniate middle ear The evolution of the auditory structures of the middle ear began with the recycling of the second gill arches in primitive fish (Braxeau and Jeffery 2008). While the first set of gill arches became the upper and lower jaws‚ the upper portion of the second gill arch‚ the hyoid arch‚ became a support structure for the cranium as the hyomandibula (Manley 2010). Examinations of Sarcopterygiian fishes such as Rhipidistians and Rhizodonts describes the role of

Ear on Arm is an ongoing conceptual work in progress which has become an example of a new technological body‚ pushing Stelarc to explore transhumanism in new ways. Ear on Arm has involved the cultivation of a prosthetic ear out of cartilage and cells‚ several surgeries‚ and the insertion of a microphone and blue-tooth transmitter that would wirelessly broadcast to the Internet the sounds of Stelarc and his environment (Schwartzman 2015). It is located on his inner forearm‚ which is anatomically

binoculars do to improve your vision‚ this personal sound enhancer circuit does for listening. This light-weight gadget produces an adjustable gain on sounds picked up from the built-in high-sensitivity condenser microphone. So you can hear what you have been missing. With a 6V (4×1.5V) battery‚ it produces good results. As shown in Fig. 1‚ a small signal amplifier is built around transistor BC547 (T1). Transistor T1 and the related components amplify the sound signals picked up by the condenser microphone

Anatomy of Hearing including Ear Structures and Brain Structures The ear‚ an organ for hearing and balance‚ is anatomically divided into three sections: the outer ear‚ the middle ear‚ and the inner ear (Henderson). Each section contains many distinct parts that assist in the task of detecting and interpreting sound which is otherwise known as hearing (Henderson). The outer ear is composed of the auricle (pinna) and the external auditory canal (ear canal) (Sisco). The outer ear functions to catch

The Ear and Hearing Loss The ear is the organ of hearing and balance in vertebrates. The ear converts sound waves in the air‚ to nerve impulses which are sent to the brain‚ where the brain interprets them as sounds instead of vibrations. The innermost part of the ear maintains equilibrium or balance. The vestibular apparatus contains semicircular canals which in turn balance you. Any movement by the head‚ and this apparatus sends a signal to the brain so that your reflex action is to
