Exocrine Glands: Unicellular and Multicellular Glands

32.6K
Exocrine glands are classified as unicellular and multicellular. The unicellular glands are scattered single cells, such as goblet cells, found in the mucous membranes of the small and large intestines. On the other hand, multicellular exocrine glands develop as secretory sheets, like the internal lining of the abdomen or chest. Such secretory sheets release their secretions directly into the lumen of these organs. In addition, some multicellular glands have deep-seated secretory units to...

The Pituitary Gland01:17

The Pituitary Gland

10.8K
The pituitary is a small endocrine organ in the sphenoid bone under the hypothalamus. Primarily, the pituitary in adults has two distinct anatomical and functional regions— the anterior and posterior lobes. During human fetal development, a third pituitary gland region called the pars intermedia atrophies and disappears. However, some of its cells migrate and exist adjacent to the anterior pituitary in adults.

The Parathyroid Glands

5.3K
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...

The Pineal Gland

5.3K
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...

The Mammary Glands

The female breast is a hemispheric projection of variable size positioned anterior to the pectoralis major and serratus anterior muscles. A fascia layer composed of dense, irregular connective tissue connects it to these muscles.
Each breast features a pigmented projection known as the nipple, through which milk emerges via closely spaced openings of ducts, referred to as lactiferous ducts. Surrounding the nipple is a circular pigmented area of skin named the areola, which appears rough due to...

Summary

Meibomian gland dysfunction (MGD) can cause evaporative dry eye and superficial punctate keratopathy (SPK). Recognizing and treating associated meibomitis with antimicrobials is crucial for effective ocular surface disease management.

Area of Science:

  • Ophthalmology
  • Ocular Surface Disease

Background:

  • Meibomian gland dysfunction (MGD) is a leading cause of evaporative dry eye, characterized by meibum stagnation, tear film instability, and superficial punctate keratopathy (SPK).
  • MGD can involve inflammation (meibomitis) due to bacterial proliferation, leading to significant ocular surface inflammation, including corneal infiltrates, neovascularization, SPK, and conjunctivitis.

Purpose of the Study:

  • To highlight the diagnostic challenge in differentiating SPK caused by dry eye from that caused by meibomitis.
  • To emphasize the importance of considering the meibomian gland and ocular surface as a single unit (MOS) for effective treatment strategies.

Main Methods:

  • Clinical observation and differentiation of SPK causes.
  • Review of treatment outcomes for dry eye and meibomitis.

Main Results:

  • Superficial punctate keratopathy (SPK) can be difficult to distinguish between dry eye and meibomitis.
  • Standard dry eye treatments may fail if meibomitis is not identified and treated with systemic antimicrobials.

Conclusions:

  • Effective management of ocular surface inflammatory diseases requires recognizing meibomitis as a distinct cause of SPK.
  • Treating meibomian gland inflammation is a more rational approach for meibomitis-related keratoconjunctivitis, improving patient outcomes.
