Question

Match the following parts of the ear with functions

$\begin{array}{cc}ColumnI& ColumnII\\ i.\text{Pinna}& a.\text{Collects Vibrations in the air}\\ ii.\text{Cochlea}& b.\text{Region between Pinna and eardrum}\\ iii.\text{Meatus}& c.\text{Transfers vibrations to ear ossicles}\\ iv.\text{Tympanic membrane}& d.\text{Translates sound to nerve impulses}\\ v.\text{Eustachian tube}& e.\text{Equalises pressure between the inner and outer ear}\end{array}$

• A. i).➡ a., ii).➡ d., iii).➡ b., iv). ➡ d, v). ➡ e.
• B. i).➡ e., ii).➡ c., iii).➡ b., iv). ➡ a, v). ➡ d
• C. i).➡ d., ii).➡ e., iii).➡ a., iv). ➡ b, v). ➡ b.
• D. i).➡ c., ii).➡ a., iii).➡ e., iv). ➡ c, v). ➡ d.

Answer 1

The correct option is A

i).➡ a., ii).➡ d., iii).➡ b., iv). ➡ d, v). ➡ e.

In reference, parts of the ear with functions:
$\begin{array}{cc}ColumnI& ColumnII\\ i.\text{Pinna}& a.\text{Collects Vibrations in the air}\\ ii.\text{Cochlea}& d.\text{Translates sound to nerve impulses}\\ iii.\text{Meatus}& b.\text{Region between Pinna and eardrum}\\ iv.\text{Tympanic membrane}& c.\text{Transfers vibrations to ear ossicles}\\ v.\text{Eustachian tube}& e.\text{Equalises pressure between the inner and outer ear}\end{array}$

Therefore, the correct option is A. – i).$\to$ a., ii).$\to$ d., iii).$\to$ b., iv). $\to$ c, v). $\to$ e.
