Study Notes

Skin Anatomy and Functions

Melanin-absorbing cells for pigmentation exist in the stratum spinosum.
The highest concentration of sudoriferous glands found on palms, soles, scalp, forehead, and underarms.
Sebum functions to mix with sweat and form the acid mantle, protecting the skin.
The stratum corneum is primarily composed of keratin cells, providing a protective barrier.
Dry skin is characterized by not being prone to acne due to its lack of excess oil.

Skin Layers

Cells in the stratum spinosum exhibit a spiny appearance and become irregularly shaped.
Sebaceous glands are responsible for producing sebum (oil) for skin lubrication.
The protective cushioning layer is the subcutaneous layer, giving body's shape and contour.
Pores are small openings on the skin associated with sudoriferous glands.
The reticular layer houses sudoriferous and sebaceous glands, sensory nerve endings, and arrector pili muscles.

Layer Specifics

Sudoriferous glands are identified as duct glands due to their structure.
Squamous cells reside in the stratum lucidum, which is found only on soles and palms.
The constantly shedding layer of the epidermis is the stratum corneum.
The stratum basale is synonymous with stratum germinativum where cell division occurs.

Skin Health and Conditions

The stratum corneum is considered the toughest layer of the skin, providing resilience.
To maintain moisture balance, the stratum corneum serves as a barrier against moisture loss.
Control of sweat excretion is managed by the nervous system.
Dry skin is the skin type least prone to acne, unlike oily or combination skin.

Skin Lesions and Infections

Bulla are lesions larger than vesicles, commonly seen in second-degree burns.
Impetigo is a highly contagious bacterial infection characterized by honey-yellow crusted lesions primarily on the face.
Steatoma typically presents on the scalp, neck, or back, known for being a fatty tumor.

Mitosis and Skin Physiology

The process of mitosis, or cell division, primarily takes place in the stratum basale.
