Which part of Human ear collects sound from its surrounding?

Pinna

The correct answer is Option (1)- Pinna

The part of the human ear that collects sound from its surrounding is the Pinna.

Pinna:

• The pinna, also known as the outer ear or auricle, is the visible, external part of the ear.
• Its main function is to collect sound waves from the surrounding environment and funnel them into the ear canal.
• The unique shape and structure of the pinna help in capturing and directing sound waves towards the ear canal.

The sound waves collected by the pinna then travel through the ear canal and reach the middle ear, where they are further transmitted to the inner ear for processing. The other structures mentioned (anvil, cochlea, and hammer) are located in the middle and inner ear and play roles in transmitting and transducing sound vibrations.
