2024年12月26日 · The ear canal is also called the external acoustic meatus, outer ear, or auditory canal. It is the part of the ear that starts at the eardrum (between the outer and middle ear) and continues to the cartilage outside the ear.

2021年7月1日 · The ear canal is a small, tube-like pathway that extends from the outer ear to the eardrum. A range of health problems can affect this sensitive area, including infection,...

The ear canal (external acoustic meatus, external auditory meatus, EAM) is a pathway running from the outer ear to the middle ear. The adult human ear canal extends from the auricle to the eardrum and is about 2.5 centimetres (1 in) in length and 0.7 centimetres (0.3 in) in diameter.

2024年3月14日 · The ear anatomy consists of three parts: the outer Ear, middle Ear, and inner Ear. The outer Ear is the part you can see, including the flap of skin called the pinna and the tube-like ear canal.

2025年2月12日 · external auditory canal, passageway that leads from the outside of the head to the tympanic membrane, or eardrum membrane, of each ear. The structure of the external auditory canal is the same in all mammals.

2023年11月3日 · The external ear, like the middle ear, serves only to conduct sound to the internal ear. It consists of the auricle and external acoustic meatus (or ear canal).

2025年1月21日 · The external acoustic meatus, also known as the ear canal, is a tubular passageway that extends from the outer ear to the tympanic membrane (eardrum). It is approximately 2.5 cm in length and is responsible for guiding sound waves from the external environment toward the middle ear.

External Ear: The ear (external auditory) canal is covered by skin. The skin closer to the outside of the ear is thick, has hair, and produces ear wax (cerumen). This thick skin covers cartilage. The skin covering the ear canal that is further inside is very thin and overlies bone.

2025年1月22日 · Each region contains distinct structures that contribute to the ear’s overall role in hearing and balance. The external ear consists of the auricle (pinna) and the external auditory canal. Its primary role is to collect and direct sound waves into the ear. Auricle (Pinna): The visible part of the ear, made of elastic cartilage and skin.

2024年7月31日 · The external auditory canal (EAC) or external auditory meatus (EAM) extends from the lateral porus acusticus externus medially to the tympanic membrane.
