The three ear bones, or ossicles, are the smallest bones in the human body, less than 1 cm easily.
The last of the ossicles of the middle ear is the stapes. It delivers the sound vibrations to the oval window separating the air environment of the middle ear from the fluid environment of the inner ear. The inner ear contains the cochlea, vestibule and semicircular canal.
The associated bones of the skull include the mandible (jawbone), hyoid bone, and auditory ossicles (malleus, incus, and stapes).
Yes, the ossicles located in the middle ear are responsible for transmitting sound vibrations from the eardrum to the cochlea in the inner ear.
No, the three small bones in the ear are collectively known as the ossicles. The stirrup, or stapes, is one of the three ossicles, along with the malleus (hammer) and incus (anvil).
The three ossicle bones are located in the middle ear which is an air space in the temporal bone. The answer to your question is YES, the skull houses the ossicles in the temporal bone.
It is the ossicles :)
Fusion or fixation of the ossicles is where one or more of the three auditory ossicles cannot transmit sound vibrations for a variety of reasons. This does cause "conduction" deafness or hearing loss.
In a starfish, the ambulacral ossicles are little calcified bony plates covering the radial canal.
YES, but it is not the same "ossicles" that are found in the mammal ear. Echinoderm ossicles are small calcium-matrix plates that make up the dermis or endoskeleton of the echinoderm. They provide protection and support to the underlying tissue.

If there is a change to the basic structure or functioning ability of your auditory ossicles, this would result in Conductive Deafness as the ossicles will not be able to transmit and amplify the sound vibrations from the tympanic membrane to the oval window.
The word "ossicle" means "little bone" The sea cucumber has calcified structures just under the skin which are called microscopic ossicles or sclerietes. There are many of these ossicles which are remnants of a previous endoskeleton.
They make up the skeleton and protect internal structures.
One cause of "Conductive Hearing Loss" can be due to the trauma and subsequent fracture of one or more ossicles, as well as the fracture of the temporal bone which houses the middle ear with its ossicles. Conductive deafness is due to the inability of the ossicles to conduct the sound vibrations from the tympanic membrane to the oval window.
Brittle stars are echinoderms with a skeleton of embedded calcite ossicles (little bones) which fuse to form an armor plate. The plates are covered by the epidermis, so that you can tell where the plates/ossicles are, but you cannot see them directly.
The ossicles can be damaged by trauma to the head, loud noises, infections such as otitis media, or other medical conditions that affect the middle ear. Over time, chronic exposure to loud noises can also cause damage to the ossicles.
