Transverse auricle muscle (M. Transversus Auriculae, Pna, Bna, Jna)

The transverse pinna muscle, also known as M. Transversus Auriculae, Pna, Bna, Jna, is a small muscle that is found in the pinna of the human ear. This muscle belongs to a group of muscles that control the movements of the auricle and contribute to its change in shape and position.

The anatomical term "M. Transversus Auriculae" indicates that this muscle overlaps or runs across the pinna. Pna, Bna and Jna are abbreviations used to refer to this muscle in various classification systems or scientific studies.

The transverse pinna muscle connects to other muscles and ligaments in the ear area. Its exact position and size may vary from person to person. However, in general, this muscle runs across the pinna and can influence its movement.

The function of the muscle, the transverse auricle, is not fully understood, and its contribution to auricular function remains the subject of research. However, it is suggested that this muscle may play a role in regulating the direction of sound waves, improving sound perception, and protecting the pinna from harmful environmental factors such as loud noise or dust.

Although the muscle, the transverse auricle, may be small and relatively unknown, understanding its structure and function is important to fully understanding the anatomy and physiology of the ears. Further research and observations will expand our knowledge about the role of this muscle and its effect on ear function.

In conclusion, the transverse pinna muscle (M. Transversus Auriculae, Pna, Bna, Jna) is a small muscle found in the pinna. Its function and significance in ear anatomy require further research. Understanding the role of this muscle may have important implications for studying ear function and developing new approaches to treating ear diseases.



The muscles that ensure mobility of the middle ear and auricle are included not only in the group of muscles of the middle ear region, but also in the system of muscles of the cervicocephalic region. Contrary to the name transverse, this muscle can be either flat or trapezoidal. The pinna muscle can be easily found by palpation. The three layers of muscles located under the skin can be traced due to the characteristics of the muscle relief. With well-developed masticatory muscles, a network of muscle bundles can be felt, extending into the soft tissues of the auditory canal. With powerful circular movements, you can feel the rounding of the facial bones in the temple area, due to the flow of blood to the muscles. This occurs directly from the branches of the external carotid artery. When making movements while eating, an ear click may be noted, which is caused by the displacement of the bone in the socket in response to compression. Thus, the muscles have the following effects: 1. The accommodative muscle helps change the position of the auditory ossicles in the ear canal in the direction of movement. 2.Castation muscles reduce the angle of the auditory tube, creating an obstacle to the penetration of sound waves. In this way, the tightness of the external auditory canal is maintained. 3. In the task with turning the head, the pressure position in the middle ear and the displacement of the eardrum are monitored. Given the importance of this muscle group, you should pay close attention to their functioning. If the disease provokes movement disorders in this area, it is important to immediately contact an otolaryngologist for examination and the appointment of additional procedures (ultrasound, radiography).
