The middle ear contains the

a. cerumen and sebaceous glands.
b. umbo and malleus.
c. vestibule and cochlea.
d. pars tensa and semicircular canals.
e. helix and antihelix

A

B umbo and malleus
The middle ear contains the ossicles, which are three small bones: the malleus (the umbo is part of the malleus), the incus, and the stapes. The tympanic membrane separates the external ear from the middle ear and is composed of the pars tensa. Cerumen and sebaceous glands lie outside the middle ear; the semicircular canals, vestibule, and cochlea lie in the inner ear. The helix and antihelix are parts of the auricle.
