auris externa - outer ear

1.

auricula, ae, f = pinna - auricle, outer portion of ear

a. helix, icis, f - gr. spiral, volute; the prominent rim

• f the auricle

b. antihelix - the inner curved rim c. scapha, ae, f - gr. light boat, skiff; the curved depression separating the helix and antihelix d. concha auriculae - concha gr. mussel , large sea- shell; the large hollow, or floor of the auricle, e. tragus, i, m - gr. he-goat; so called for the tuft of hair which grows there, which resembles a goat's beard.- projection anterior to the external

• pening of the ear

f. antitragus - projection opposite the tragus g. lobulus auriculae - the lowest fleshy part of the auricle

2. meatus acusticus externus - the passage/ear canal

from the auricle to the tympanic membrane 3.

tympanum, i, m = -TYMPAN- (o)

auris media - middle ear

1. membrana tympani = tympanica - tympanic membrane 2. cavitas (cavum) tympani - tympanic cavity 3. tuba auditiva (Eustachii) dextra / sinistra - auditory tube (*Eustachian tube - after the name of

the Italian anatomist Bartolomeo Eustachio 1514 – 1574)

4.

• ssicles

a. malleus, i, m - hammer-shaped bone,

• r club * named so by the Ital. anatomist

Achillini (1463-1512), as it appears to strike the tympanic membrane like a hammer

b. incus, udis, f - anvil-shaped bone; *

term, introduced by Andreas Vesalius to describe the bone which is struck by the hammer

c. stapes, edis, m - stirrup-shaped bone;

*so called because the bone is shaped like a stirrup (loop shaped device attached to each side of the saddle to support the rider’s foot)– this was an invented Modern Latin word for "stirrup", for which there was no classical Latin word, as the ancients did not use stirrups

auris media = gr. -TYMPAN- (o) * used for the whole middle ear, and

also a term-element precisely for the eardrum tympanum

Оtology. Some pathological conditions

• Otosclerosis fenestrae ovalis - otosclerosis of the oval window* (the oval opening in the middle

ear)

• * When the diagnosis phrase has to express a location of particular, more specific

anatomic structure you need to use Anatomical Latin in Genitivus
