Goblet cell population in the normal middle ear and Eustachian tube of children and adults

Insights

Goblet cell density in the Eustachian tube increases with age, reaching high levels in adults. Middle ear goblet cell density is highest in infants and decreases with age.

Area of Science:

  • Otolaryngology
  • Anatomy
  • Histology

Background:

  • Goblet cells are crucial for mucosal defense.
  • Understanding their distribution in the Eustachian tube and middle ear is important for respiratory health.

Purpose of the Study:

  • To investigate the age-related distribution and density of goblet cells in the human Eustachian tube and middle ear.

Main Methods:

  • Analysis of 54 temporal bones from individuals across various age groups (prematures, infants, children, adults).
  • Quantification of goblet cell counts in different regions of the Eustachian tube and middle ear.

Main Results:

  • Eustachian tube goblet cell density is low in prematures, increasing through childhood to high levels in adults, particularly at the pharyngeal orifice.
  • Middle ear goblet cell density is low in prematures, slightly increases in infants, and then decreases in older children and adults.
  • Goblet cells are present throughout the middle ear, with density decreasing in a specific anatomical sequence.

Conclusions:

  • Goblet cell distribution and density significantly change with age in the Eustachian tube and middle ear.
  • These findings provide normative data for goblet cell populations in the auditory system.
  • Understanding these changes may offer insights into age-related susceptibility to ear conditions.

Classification of Epithelial Tissues: Simple Epithelium

Simple epithelium consists of a single layer of cells that lines body cavities and blood vessels. The shape of the cells in the epithelium reflects the function of the tissue. Cells in simple squamous epithelium appear as thin scales with flat, elliptical nuclei that mirror the form of the cell.
Because of the thinness of the cells, simple squamous epithelium is present where the rapid passage of chemical compounds is observed. For example, the endothelium that lines the capillaries and vessels...
Anatomy of the Ear01:16

Anatomy of the Ear

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...
The Parathyroid Glands00:59

The Parathyroid Glands

The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by producing...

Structure and Function of Erythrocytes

There are between 4.2 and 6 million erythrocytes, also known as red blood cells, in every microliter of blood. These cells are small, flattened biconcave discs with centers that are depressed.
The erythrocyte plasma membrane is associated with proteins such as spectrin, which forms a flexible cytoplasmic meshwork. This meshwork allows erythrocytes to twist, turn, become cup-shaped, and regain their biconcave shape as they pass through narrow capillaries. Additionally, erythrocytes can form...

Alveoli and Alveolar Ducts

The respiratory zone of the human body, which stands in contrast to the conducting zone, comprises the structures that actively participate in the exchange of gases. The initiation of this zone is marked by the terminal bronchioles converging into respiratory bronchioles, the tiniest bronchiole classification. The respiratory bronchioles give way to the alveolar ducts that opens into a congregation of alveoli. Actively involved in gas exchange, alveoli resemble tiny sacs similar to clusters of...
Microbiota of the Respiratory Tract01:29

Microbiota of the Respiratory Tract

The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more like...
