What are the three parts of the ear and their functions?
The ear is divided into three parts:
- Outer ear: The outer ear includes an ear canal that is is lined with hairs and glands that secrete wax.
- Middle ear: Three tiny bones — the malleus, incus, and stapes — within the middle ear transfer sound vibrations from the eardrum to the inner ear.
What separates the outer ear from the middle ear?
tympanic membrane
Hear this out loudPauseThe tympanic membrane is also called the eardrum. It separates the outer ear from the middle ear. When sound waves reach the tympanic membrane they cause it to vibrate. The vibrations are then transferred to the tiny bones in the middle ear.
Is the right ear proximal to the left ear?
frontal The body section that divides the right ear from the left ear is sagittal anatomical relationship of the wrist to the elbow the elbow is proximal to the wrist The body tries to maintain a constant body temperture homeostasis a subdivision of the thoracic cavity mediastinum divides the body into front and rear parts frontal plane
Which is the body section divides the right ear from the left ear?
The body section that divides the right ear from the left ear is a _____ section frontal the body section that divides the body into anterior (The nose) and posterior(the head) is a _________ section midsagittal section a section that divides the body into mirror images is a ________ section Dorsal and ventral
Which is plane divides the body into right and left regions?
This plane divides the body into right and left regions. Median or Midsagittal Plane: Sagittal plane that divides the body into equal right and left regions. Parasagittal Plane: Sagittal plane that divides the body into unequal right and left regions.

What are the names of the bones in the ear?
The bones, named for their shapes, are the malleus, incus, and stapes—commonly called the hammer, anvil, and stirrup, respectively. The “handle” of the malleus attaches to the internal surface of the tympanic membrane. The head of the malleus articulates with the body of the incus.
What makes up the external part of the ear?
The external (outer) ear consists of the auricle, external auditory canal, and eardrum (Figure 1 and 2). The auricle or pinna is a flap of elastic cartilage shaped like the flared end of a trumpet and covered by skin.
