Yellowing of the Skin

• Yellowing of the skin and whites of the eyes indicates a potential internal issue, particularly with the liver.

• Clinical Significance:

  • When you observe jaundice, it's essential to assess liver function, as it could indicate improper detoxification of blood.

  • Hemoglobin is not being broken down correctly, leading to toxic accumulation.

• Jaundice in Infants:

  • Premature infants may experience jaundice due to underdeveloped liver function.

  • The skin may appear waxy yellow.

  • Infants often receive treatment in incubators to help regulate bilirubin levels until their liver matures and functions properly.

Cutaneous Plexus and Skin Layers

• Importance of the Cutaneous Plexus:

  • The cutaneous plexus plays a critical role in skin health and appearance.

  • Focus on the papillary layer, which is essential for nutrient supply and support to the epidermis.

• Layers of the Integumentary System:

  • The integumentary system primarily comprises two layers: the epidermis and dermis.

    • These layers interlock to maintain skin integrity and function.

• Skin Classification:

  • Understanding the difference between thick skin and thin skin is crucial:

    • Thick skin is found in areas with high abrasion (e.g., palms, soles).

    • Thin skin covers most other body areas.

• Role of Melanin:

  • Melanin is responsible for skin pigmentation and offers protection against UV radiation.

Hair Types and Glandular Structure

• Hair Classification:

  • Recognize the difference between types of hair:

    • Terminal hair is longer and coarser (e.g., scalp, eyebrows).

    • Understand the functions of hair in various areas of the body.

• Glandular Structures in Skin:

  • Sebaceous glands: Produce oils to lubricate skin and hair.

  • Sweat glands: Aid in thermoregulation and waste elimination.

• Avoid overloading on glandular information, but understand their relevance in skin health.
