Lingula: structures and functions

Lingula is a term that describes several different structures within the body of humans and other animals. In this article we will look at several meanings of this term and their functions.

1. Cerebellar uvula

The cerebellar uvula is a thin, unpaired structure that projects forward from the back of the brain. It is connected to the superior medullary velum and plays an important role in coordinating movement and balance.

In addition, the uvula cerebellum is involved in processing information about muscle tone and body position in space. It is also associated with the function of vision, hearing, balance and other sensory systems.

2. Lung uvula

The uvula is a small area of ​​the upper lobe of the left lung, located between the cardiac notch and the oblique fissure. It gets its name from its shape, which resembles a tongue.

The function of the uvula is not fully understood, but it is believed to be involved in the breathing process and maintains a balance between pressure in the lung and pressure in the chest.

3. Tongue of the lower jaw

The lingula of the mandible is a bony plate on the inner surface of the lower jaw, located above its angle. It serves as an attachment point for muscles that are involved in chewing and speaking.

4. Tongue of the sphenoid bone

The sphenoid lingula is a small paired projection on the sphenoid bone located lateral to the carotid sulcus. It also serves as an attachment point for muscles involved in chewing and speaking.

5. The uvula of the seminiferous tubule

The uvula seminiferous tubule is a structure in the male gonads that helps produce sperm. The seminiferous tubules are a system of small convoluted tubules in which sperm develop. The wall of the seminiferous tubule is lined with a layer of spermatogenic epithelium, consisting of spermatogenic cells at different stages of development and supporting cells.

Sertoli cells form the microenvironment of developing sperm and carry out their trophism. Biochemical maturation of sperm occurs in the epididymis (epididimis), which also secretes a fluid that dilutes the sperm. Located between the tubules, interstitial cells (or Leydig cells) are the main producers of androgen, which are the main male sex hormones.

In general, Lingula is a term that describes several different structures within the body of humans and other animals. Each structure has its own unique function that contributes to the overall functioning of the body. Although some of these structures are not fully understood, understanding them helps improve our medical practice and helps us better understand the functioning of the body as a whole.

The tongue (Lingula) is a small anatomical structure that can represent:

1. A thin, unpaired, slightly protruding part of the cerebellar vermis, connected to the superior medullary velum. The cerebellar vermis is a brain structure located in the posterior cranial fossa.

2. A small area of ​​the upper lobe of the left lung, which is located between the cardiac notch and the oblique fissure. It separates the apex of the lung from its lower and middle lobes.

3. A bony plate on the inner surface of the lower jaw, above its angle. It serves as the attachment point for the muscles of the tongue.

4. A small paired projection of the sphenoid bone located lateral to the carotid groove. The sphenoid bone is an unpaired bone at the base of the skull.

Thus, the term "uvula" can refer to a variety of small structures, including parts of the brain, lungs, jaw, and base of the skull. These structures play a certain role in the anatomy and physiology of the corresponding organs and systems.

Uvula (lingvula)

The uvula is a thin, unpaired part of the cerebellar vermis. It connects to the superior medullary velum. The uvula is located in the upper part of the brain.

Also, the uvula is a small area of ​​the upper lobe of the lung. It is located between the cardiac notch and the oblique fissure.

The bone plate is located on the inner surface of the lower jaw. It is located above the angle of the jaw.

A small paired projection in the sphenoid bone is located lateral to the carotid groove. The processes of sperm development take place in it.

The wall of the seminal canal is lined with layers of spermatogenic epithelium. It consists of spermatogenic cells at different stages of maturation and supporting cells.

Sertoli cells form the microenvironment for sperm development and also provide their trophic support.

Biochemical maturation of sperm occurs in the epididymis.
