Question

Student A told Student B that his ears are the most lateral structures on his head. Student B corrected Student A and said that his ears are actually bilateral structures. Which student is correct, and why? (2 points)



Student A, because lateral structures are found far from the midline of the body.


Student B, because bilateral structures are paired on either side of the body.


Neither student, because ears are medial structures.


Both students, because ears are both lateral and bilateral

Answer 1

Answer: Both students, because ears are both lateral and bilateral

Explanation: the first student is right by saying the ear is the most lateral structure on his head. Lateral means how far from the middle line the structure is if an imaginary line is drown from head down on an body, dividing the animal into two equal left and right hemispheres.

The second student is also right by saying the ear is a bilateral structure. Bilateral structures are structures with two opposite parts on the opposite body hemispheres if a lateral middle line is drawn on a body from head down, dividing the body into two equal left and right hemispheres. Bilateral structures includes the ear, eyes, hand, legs etc.
