Larynx

Larynx

The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...

Functional Brain Systems: Limbic System

Functional Brain Systems: Limbic System

The limbic system, often called the "emotional brain," is a complex set of structures located deep within the brain. The intricate network of the limbic system supports a wide range of psychological functions, from emotional regulation to memory formation and sensory processing. This functional brain region encompasses specific parts of the diencephalon and the cerebrum, integrating the higher mental functions of the cerebral cortex with the primitive emotional responses of the deep brain...

The Thyroid Gland

The Thyroid Gland

The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Hypodermis

Hypodermis

The hypodermis (the subcutaneous layer or superficial fascia) is present directly below the dermis. It connects the skin to the underlying fascia (fibrous tissue) of the bones and muscles. It is not strictly a part of the skin, although the border between the hypodermis and dermis can be difficult to distinguish. The hypodermis consists of well-vascularized, loose, areolar connective tissue and adipose tissue, which functions as a mode of fat storage and provides insulation and cushioning for...

The Pineal Gland

The Pineal Gland

The pineal gland, a diminutive endocrine structure named for its pinecone-shaped appearance, is situated atop the third ventricle within the diencephalon region of the forebrain. This gland, composed of secretory cells known as pinealocytes arranged in compact cords and clusters around dense particles of calcium salts, plays a pivotal role in hormonal regulation.
The primary secretion of the pineal gland is the hormone melatonin, derived from serotonin. The concentration of melatonin in the...

Diencephalon: Anatomical Regions

Diencephalon: Anatomical Regions

The diencephalon, etymologically translated as 'through brain,' plays an integral role as the conduit between the cerebrum and the vast extent of the nervous system. However, the olfactory system is an exception, as it interfaces directly with the cerebrum. The diencephalon, deeply ensconced beneath the cerebrum, primarily consists of three paired structures — the thalamus, hypothalamus, and epithelamus. It also includes accessory structures such as the subthalamus, which houses the subthalamic...

Summary

This summary is machine-generated.

The laryngeal fat body (LFB) is located in the pre-epiglottic (PE) space. Understanding this anatomy is crucial for detecting early signs of cancer spread.

Area of Science:

Anatomy
Surgical Anatomy
Head and Neck Anatomy

Background:

The laryngeal fat body (LFB) and its surrounding pre-epiglottic (PE) space are important anatomical structures.
Accurate anatomical knowledge is essential for clinical practice, particularly in oncology.

Purpose of the Study:

To detail the anatomy and topographical location of the laryngeal fat body (LFB).
To describe the anatomical characteristics of the pre-epiglottic (PE) space.

Main Methods:

Histological analysis of fetal and newborn head and neck specimens.
Dissection of adult neck specimens.
Computed Tomography (CT) and Magnetic Resonance Imaging (MRI).

Main Results:

The LFB is situated within the PE space, located anteriorly below the hyoid bone.
The PE space is divided into two compartments by a median septum.
The LFB is composed of pure fat lobules without a distinct capsule.

Conclusions:

Histological findings of the PE space align with previous dissection studies.
While fat content is agreed upon, the presence of an LFB capsule varies among studies.
CT and MRI are effective for analyzing these anatomical structures.
Knowledge of the PE space and LFB is vital for identifying early carcinological extension.
