Middle Ear Diagram Model

A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the power and signal connections between the devices.
A wiring diagram usually gives information about the relative position and arrangement of devices and terminals on the devices, to help in building or servicing the device. This is unlike a schematic diagram, where the arrangement of the components' interconnections on the diagram usually does not correspond to the components' physical locations in the finished device. A pictorial diagram would show more detail of the physical appearance, whereas a wiring diagram uses a more symbolic notation to emphasize interconnections over physical appearance.
A wiring diagram is often used to troubleshoot problems and to make sure that all the connections have been made and that everything is present.
Architectural wiring diagrams show the approximate locations and interconnections of receptacles, lighting, and permanent electrical services in a building. Interconnecting wire routes may be shown approximately, where particular receptacles or fixtures must be on a common circuit.
Wiring diagrams use standard symbols for wiring devices, usually different from those used on schematic diagrams. The electrical symbols not only show where something is to be installed, but also what type of device is being installed. For example, a surface ceiling light is shown by one symbol, a recessed ceiling light has a different symbol, and a surface fluorescent light has another symbol. Each type of switch has a different symbol and so do the various outlets. There are symbols that show the location of smoke detectors, the doorbell chime, and thermostat. On large projects symbols may be numbered to show, for example, the panel board and circuit to which the device connects, and also to identify which of several types of fixture are to be installed at that location.
A set of wiring diagrams may be required by the electrical inspection authority to approve connection of the residence to the public electrical supply system.
Wiring diagrams will also include panel schedules for circuit breaker panelboards, and riser diagrams for special services such as fire alarm or closed circuit television or other special services.

The middle ear consists of three bones: the hammer (malleus), the anvil (incus) and the stirrup (stapes), the oval window, the round window and the Eustrachian tube. The bones of the middle ear. The eardrum is very thin, measures approximately 8 10 mm in diameter and is stretched by means of small muscles. The pressure from sound waves makes the eardrum vibrate. The vibrations are transmitted ...

This lumped parametric model consisting of 6 messes connected by several pairs of spring and dashpot is proposed for mechanical analysis of the ear, including the external ear canal, tympanic membrane, middle ear ossicles, and cochlea. The air inside the external ear canal was represented by the mass M 1, which coupled the mass M

Helix: It is the prominent outer rim of the external ear. Antihelix: It is the cartilage curve that is situated parallel to the helix. Crus of the Helix: It is the landmark of the outer ear, situated right above the pointy protrusion known as the tragus. Auditory Ossicles: The three small bones in the middle ear, called malleus, stapes, and incus, are connected.

The ear has external, middle, and inner portions. The outer ear is called the pinna and is made of ridged cartilage covered by skin. Sound funnels through the pinna into the external auditory ...

Human Ear – Anatomy, Parts (Outer, Middle, Inner), Diagram. Posted by Dr. Chris. The human ear can be divided into 3 parts – external, middle and internal – with each part playing an integral role in the sense of hearing, while the internal ear has an added function for equilibrium. The external (outer) and middle ear transmit sound waves to the internal (inner) ear. Here mechanical ...

Outer Ear composed of three major parts: Tragus; Helix; lobule. Middle Ear. Middle Ear is also known Tympanic Cavity. Tympanic cavity plays a significant role in an individual’s aptitude to Hear.
