Unveiling Skin Secrets: Exploring the Structure of Skin Through a Mindmap
Embark on a visual journey through the intricate layers and components of the skin with our detailed mind map.
Explore the epidermis, dermis, and subcutaneous tissue, visualizing the structures like hair follicles, sweat glands, and blood vessels that make up this vital organ.
Understand the functions of each layer in protecting, regulating temperature, and sensation
Here is a detailed comprehensive mind map of the physiology topic “Structure of Skin”:
Central Idea: Structure of Skin
Main Branches:
- Epidermis
- Dermis
- Hypodermis
- Skin Appendages
- Functions of Skin
Sub-Branches:
1. Epidermis
- Stratified Squamous Epithelium
- Basal layer: stem cells, melanocytes
- Spinous layer: keratinocytes, desmosomes
- Granular layer: keratinocytes, keratohyalin granules
- Corneum layer: dead, keratinized cells
- Epidermal cells
- Keratinocytes: produce keratin, form barrier
- Melanocytes: produce melanin, protect from UV
- Langerhans cells: immune function, antigen presentation
- Merkel cells: sensory function, touch and pressure
2. Dermis
- Papillary dermis: thin, loose connective tissue
- Papillae: finger-like projections, increase surface area
- Reticular dermis: thick, dense connective tissue
- Collagen fibers: provide strength, elasticity
- Elastic fibers: provide elasticity, recoil
- Dermal cells
- Fibroblasts: produce collagen, elastin
- Macrophages: immune function, phagocytosis
- Mast cells: immune function, allergic responses
3. Hypodermis
- Subcutaneous tissue: loose connective tissue
- Adipocytes: store energy, insulate
- Fibroblasts: produce collagen, elastin
- Hypodermal cells
- Adipocytes: store energy, insulate
- Fibroblasts: produce collagen, elastin
4. Skin Appendages
- Hair follicles
- Hair shaft: keratinized, dead cells
- Hair root: living cells, growth occurs
- Sweat glands
- Eccrine glands: produce sweat, regulate temperature
- Apocrine glands: produce sweat, respond to stress
- Sebaceous glands: produce sebum, moisturize skin
- Nails: keratinized, dead cells, protect tips of fingers and toes
5. Functions of Skin
- Barrier function: prevent water loss, protect from external factors
- Thermoregulation: regulate body temperature
- Sensory function: detect touch, pressure, temperature, pain
- Immune function: protect against infection, disease
- Vitamin D production: produce vitamin D, regulate calcium levels
This mind map provides a comprehensive overview of the structure of skin, including the epidermis, dermis, hypodermis, skin appendages, and functions of skin.
