2025年2月12日 · Human ear, organ of hearing and equilibrium that detects and analyzes sound by transduction and maintains the sense of balance. Anatomically, the ear has three distinguishable parts: the outer, middle, and inner ear. Learn about the anatomy and physiology of the human ear in this article.

The ear muscles are supplied by the facial nerve, which also supplies sensation to the skin of the ear itself, as well as to the external ear cavity. The great auricular nerve , auricular nerve , auriculotemporal nerve , and lesser and greater occipital nerves of the cervical plexus all supply sensation to parts of the outer ear and the ...

2023年11月3日 · All muscles of the external ear are associated with the auricle and are innervated by posterior auricular branches of the facial nerve (CN VII). They are classified into two groups, intrinsic and extrinsic. Intrinsic muscles contribute to defining the shape of the auricle by passing between its cartilaginous parts. They are: helicis major ...

2024年3月14日 · The human Ear does two main jobs: it helps us hear and keeps us balanced. It works by turning sound waves into signals our brains can understand. 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.

2022年11月24日 · There are two groups of muscles associated with the external ear. The intrinsic group of muscles consists of the tragicus and antitragicus, obliquus auriculae, transversus auriculae and the helicis major and minor. The tragicus muscle …

2020年9月13日 · The human ear has three segments: external, middle, and inner ear. The tensor tympani muscle is one of the two muscles in the middle ear. What are the three segments of the ear?

2025年2月12日 · The lobule, the fleshy lower part of the auricle, is the only area of the outer ear that contains no cartilage. The auricle also has several small rudimentary muscles, which fasten it to the skull and scalp. In most individuals these muscles do not function, although some persons can voluntarily activate them to produce limited movements.

2021年11月15日 · The ear can be divided into three parts: the external, middle and inner ear. The ears are an organ of hearing and balance, converting information from our external environment into electrical signals that can be processed by the brain.

Different sources group muscles differently, regarding physical features as different parts of a single muscle or as several muscles.

Hearing, or audition, is the transduction of sound waves into a neural signal that is made possible by the structures of the ear (Figure 15.3.1). The large, fleshy structure on the lateral aspect of the head is known as the auricle.
