Study Notes
Integumentary System Structure
- The main component of the integumentary system located in the dermis layer is collagen.
- The nail body is formed in the nail matrix that protects the tips of our fingers and toes.
- The skin is composed of two main layers: the epidermis and the dermis.
- The epidermis is made of keratinized, stratified squamous epithelium.
Glands and Sweat
- Sebaceous glands primarily help to lubricate and waterproof the skin and hair.
- Sudoriferous glands produce sweat to cool the body when it becomes warm.
- The secretion of sebum by sebaceous glands is stimulated by hormones that become active in puberty.
Nerve Structures and Skin Functions
- Meissner's corpuscles and Pacinian corpuscles are types of sensory nerve structures in the skin that detect touch, surface temperature, and pain.
- The main function of the integumentary system is to protect the body from external damage, regulate body temperature, and aid in the senses of touch and feel.
- Cholinergic nerve fibers in the skin ensure communication to and from the brain.
Vitamins and Skin Conditions
- Vitamin D is synthesized by the epidermal layer of human skin when exposed to UV radiation.
- The active chemical form of vitamin D is calcitriol.
