Nerves of the Labial Posterior of the Labia Majora (N. Labiales Posteriores, Pna, Bna)

Labial nerves of the posterior labia majora (N. Labiales Posteriores, PNA, BNA): anatomical review

Introduction:

The posterior labial nerves of the labia majora (N. Labiales Posteriores, PNA, BNA) are nerve fibers that innervate the posterior part of the labia majora in humans. They are part of the nervous system responsible for transmitting sensation and movement signals to this area of ​​the body. In this article we will look at the anatomy and function of the labial nerves of the posterior labia majora.

Anatomy:

The labial posterior labia majora nerves run along the back of the labia majora and provide innervation to this area. They are branches of a nerve that receives its initial signals from the nerve trunk. Although the exact number and location of these nerves may vary slightly from person to person, their overall function remains the same.

Functions:

1. Sensation: The labial nerves posterior to the labia majora are the main source of sensation in the posterior portion of the labia majora. They transmit signals about tactile sensations, temperature and painful stimuli in this area. Thanks to these nerves, we can feel touch, pressure and other stimuli that affect the back of the labia majora.

2. Motor function: Along with sensation, the labial nerves of the posterior labia majora also play a role in controlling some movements in this area. They innervate the muscles that control lip movement, allowing us to perform various functions such as smiling, lip gestures and speech.

Conclusion:

The posterior labial nerves of the labia majora (N. Labiales Posteriores, PNA, BNA) are an important part of the nervous system that provides sensation and movement in the posterior part of the labia majora. They transmit signals about tactile sensations, pain and temperature, and also control lip movements. Understanding the anatomy and function of these nerves is important for medical professionals such as surgeons, dentists and neurologists who treat and diagnose problems associated with this area of ​​the body.

It is important to note that this article provides only an overview of the anatomy and function of the labial nerves of the posterior labia majora. More detailed and specific studies can be conducted to gain a deeper understanding of this area and its connections with other structures in the human body. If you have any problems or questions related to the posterior labia majora nerves, it is recommended that you contact a qualified healthcare professional for further advice and treatment.

Nerves labial major labial LAD LNA. Sensitive n. labialis posticus, nn. genitofemoralis, genitotibius and n. obturatorius recurrens. They are responsible for the innervation of the lateral and anterior parts of the labia majora. Engines n. vaginalis - innervate the bulbospongiosal ridge and la. labiorum inferiorum laterales In the proximal parts of the subcutaneous tissue of the lateral part of the lower lip, the branches of n. cutaneus clitoridis posterior In women, the branches of the nervi n. genitalis communicans.
