Insects have skeleton that is present outside their body which is known as exoskeleton.
External appendages of radiates push the water outside in the backward direction and moved in the forward direction, while bilaterians moves from place to place through their legs which are specialized for this movement and their muscle in their hands are used for holding things.

As the patient is holding his ears there is a problem associated with the ears. The patient may be suffering from hearing loss.
Hearing loss can be due to neuronal damage or problem with the conduction of soundwaves. If the hearing loss is due to nerve damage it is termed sensorineural hearing loss. If it is due to a conduction problem it is called conductive hearing loss.
Hearing loss can be caused due to genetic reasons, trauma, or injury. Treatment depends on the type of hearing loss. For conductive hearing loss hearing aids are prescribed to the patients.
