Question

What is the ear sturcture of dogs ?​

Answer 1

The ear is an organ of hearing and an organ of balance. It consists of the outer, middle, and inner ear.

The outer ear includes the pinna (the part you see that is made of cartilage and covered by skin, fur, or hair) and the ear canal. The pinna is shaped to capture sound waves and funnel them through the ear canal to the eardrum. In dogs, the pinnae are mobile and can move independently of each other. The size and shape of the pinnae vary by breed. The ear canal of the dog is much deeper than that of people and creates a better funnel to carry sound to the eardrum. The average dog can hear about 4 times better than the average person, including sounds at higher frequencies than can be detected by the human ear.

The middle ear includes the eardrum and a small, air-filled chamber that contains 3 tiny bones: the hammer, anvil, and stirrup. It also includes 2 muscles, the oval window, and the eustachian tube (a small tube that connects the middle ear with the back of the nose, allowing air to enter the middle ear).

The inner ear is a complex structure that includes the cochlea (the organ of hearing) and the vestibular system (the organ of balance).
