The ears begin their development during the fifth week of pregnancy. Ear formation starts from a few small bulges called branchial arches. Portions of the branchial arches form into structures called auricular hillocks. The auricular hillocks grow and join together to form the outer ears.
During the fifth month, the inner and middle parts of the ear develop, but won't be completely finished until birth.

What else can I help you with?
Can you feel fetal hiccups from the outside?
like fetal hiccups?? yes you can feel them and they can be detected with a fetal doppler. but they can not be heard out loud by the naked ear
What is the long external fold of the ear called on a fetal pig?
The external fold of the fetal pig ear is known as the pinna or auricle. It's most commonly referred to simply as the "outer ear".
What is a fetal pig's pin nae?
If you mean pinna, it's the ear.
Why there is no lymphatic vessels in the bone marrow and coat of the eye and internal ear and fetal placenta and central nerve system?
Innate immune system
How does the process of ear development in a fetus contribute to their overall growth and development?
The process of ear development in a fetus is important for their overall growth and development because it allows them to hear sounds and voices in the womb. This helps with brain development and language acquisition, laying the foundation for communication skills later in life.
What is the function of pinna in fetal pigs?
The pinna in fetal pigs, also known as the external ear flap, helps to capture and direct sound waves into the ear canal. This aids in the pig's ability to detect and locate sounds in its environment, providing important auditory information for survival and communication.
Can you put an earring in your preauricular pit?
No, you cannot put an earring in your preauricular pit. The preauricular pit, also known as a preauricular sinus or fistula, is a small hole or indentation located near the external ear. It is a congenital malformation that forms during fetal development and does not have a through-and-through passage like an ear piercing. Attempting to insert an earring into a preauricular pit can cause infection, irritation, and potential complications.
Which of these processes led to the development of different ear sizes in foxes?
Natural Selection
What is the Doppler method of fetal monitoring?
The Doppler method uses ultrasound; it involves a handheld listening device that transmits the sounds of the heart rate through a speaker or into an attached ear piece.
Carnivores Eg dogs cats have a little flap on the outer edge of their ears. It is almost like a little pouch. Does anyone know what it is for?
Good question! It is formed around the cartilage support of the "pinna" (outer ear/ear flap). It is most comparable to our own ear lobes. As far as I know it has no major function, like the lobes of our own human ears, but it's size and shape will be dictated genetically. It is most likely a remanant of fetal ear development in the womb.
How can the presence of pee in the ear affect the development or treatment of an ear infection?
The presence of urine in the ear can introduce bacteria and potentially worsen an existing ear infection or hinder its treatment. Urine can introduce harmful bacteria into the ear canal, leading to further inflammation and complications in the infection. It is important to keep the ear clean and dry to prevent any additional complications.
