Question

What part of the skeleton forms the earlobe?

Answer 1

Hint: The human earlobe is also known as lobulus auriculae is made up of tough aerial and adipose connective tissues. It lacks the firmness and elasticity of the rest of the auricle i.e the external structure of the ear. The lower lobe is connected to the side of the face which is not free hanging.

Complete answer:
The ear lobe is the external part of the ear. It is present in the pinna. The earlobe has a rich blood supply which helps to warm the ears and maintain balance. Earlobes do not have any major biological function. The earlobe has many nerve endings, and also lies in an erogenous zone. The earlobe is made up of cartilage which is present as the covering of the joint and lacks blood vessels.
Earlobes are smooth, but at times it exhibits creases. The creased earlobes are at times associated with genetic disorders in children, including Beckwith-Wiedemann syndrome. In some early studies, earlobe creases are associated with an increased risk of heart attack and coronary heart disease or coronary artery disease. But more recent studies have concluded that, since earlobes become more creased with age, older people are more likely to have heart disease than younger people. Age determines the factor for heart diseases rather than the ear lobe creases. The earlobe crease is also known as Frank's Sign.

Thus, the correct answer is Cartilage.

Note:
 The cartilage is not as rigid as bone but is also less flexible than the muscular tissue. The most frequent complications connected with wearing earrings are i.e piercing ear lobes are inflammation, keloids, loss of tissue by tearing, and mechanical division of earlobes.
