The book (also called the libretto) is the least appreciated and yet most dramatically important element of a musical. It is the narrative structure that keeps the score from being nothing more than a disjointed medley of songs.
Another term for the eardrum is the tympanic membrane, which is the scientific term for the eardrum. The tympanic membrane is a circular layer of tissue that separates the outer ear from the middle ear. It is incredibly thin and only measures roughly 0.1 millimeter thick. Continue Reading.
Not to be confused with the secondary tympanic membrane of the round window. In human anatomy, the eardrum, or tympanic membrane, is a thin, cone-shaped membrane that separates the external ear from the middle ear in humans and other tetrapods.Its function is to transmit sound from the air to the ossicles inside the middle ear, and then to the oval window in the fluid-filled cochlea.Hence, it ultimately converts and amplifies vibration in air to vibration in fluid. The malleus bone bridges the gap between the eardrum and the other ossicles.he pars tensa forms most of the tympanic membrane. Its periphery is thickened to form a fibrocartilaginous ring called the anulus tympanicus. The central part of the pars tensa is tented inwards at the level of the tip of malleus and is called the umbo.
