Study Notes
Vitamin D Precursors and Activation
- Precursors for Vitamin D are created in the skin.
- Vitamin D is activated in the liver and kidneys.
- Activated Vitamin D stimulates organs to produce proteins.
Integumentary System Components
- Integumentary system includes the hair matrix cells, melanocytes, melanosomes, sebaceous glands, eccrine sweat glands, parts of hair and hair follicle layers, pilosebaceous units, and fingernails.
- False integumentary refers to a specific feature or structure.
- The dermis (true skin) is connective tissue, containing fibroblasts.
- Arrector pili muscles are smooth, involuntary muscles innervated by the parasympathetic nervous system.
Skin Structure and Function
- The skin's layers include the epidermis (epithelium) and dermis (connective tissue).
- The papillary and reticular plexus are structures within the skin.
- Keratinization is a process in the skin.
- Skin color is influenced by melanin.
- Melanocytes produce melanin.
- Sweat glands and sebaceous glands are important components of the skin, differing in their functions.
Tissue Connections and Proteins
- Tissue cell connections include gap junctions and tight junctions, with corresponding proteins involved in their formation and function.
Relationships between components of the skin
- The relationships between various components, such as hair follicles and associated glands, are described in the provided information. Examples include the pilosebaceous units.
