Study Notes
Mucous Tissue
- Composed of a lamina propria featuring epithelial sheets supported by connective tissue.
- Common locations: respiratory, digestive, urinary, and reproductive tracts.
- Functions include protection, secretion, lubrication, and absorption.
Serous Tissue
- Consists of simple squamous epithelium and areolar connective tissue.
- Common locations: internal ventral body cavities and organ surfaces.
- Functions to produce lubricating fluid that reduces friction.
Cutaneous Tissue
- Made up of epithelial epidermis and connective tissue dermis.
- Covers the body’s exterior.
- Main functions: protection from external threats and prevention of water loss.
Synovial Tissue
- A type of connective tissue.
- Lines joint cavities in synovial joints.
- Produces lubrication to decrease friction within joints.
Skin Defense Mechanisms
- Epidermal dendritic cells and macrophages serve as biological barriers.
- Intact epidermis provides a mechanical barrier.
- Bacterial secretions and keratin function as chemical barriers.
- Melanin and acid mantle assist in chemical protection.
Sunburn Effects
- Mild sunburn inhibits immune response by depressing macrophage activity.
Sweat Glands and Temperature Regulation
- Increased body temperature activates sweat glands through the sympathetic nervous system.
- Sweat evaporation carries heat away from the body, aiding in temperature homeostasis.
Cutaneous Sensory Receptors
- Part of the nervous system.
- Detects stimuli such as temperature, pain, deep pressure, and light pressure.
Vitamin D Synthesis
- Synthesized when UV light modifies cholesterol molecules in the skin.
- Essential for the absorption and metabolism of calcium ions.
Skin Layers and Features
- Stratum lucidum: translucent cells with keratin.
- Stratum corneum: composed mainly of dead cells, scalelike, constantly flaking off.
- Papillary layer of the dermis is responsible for fingerprints.
- Dermis is vascularized, containing elastic and collagen fibers.
- Stratum basale: site of rapid cell division and melanin formation.
Skin Color and Pigmentation
- Melanin is most responsible for skin color in dark-skinned individuals.
- Carotene provides an orange hue to the skin.
- Hemoglobin is prevalent in the blood vessels, influencing light-skinned coloration.
Thermal Regulation
- Skin helps dissipate body heat through radiation and sweating.
- Fat in the subcutaneous tissue layer below the dermis insulates the body.
Skin Health Concerns
- Vitamin D3 is manufactured in the skin.
- Loss of skin elasticity contributes to wrinkling.
- Decubitus ulcers occur when skin cells lack oxygen.
- Cyanosis indicates inadequate blood oxygenation.
True or False Statements
- Sweat glands secrete a saltwater solution. (False: it's sebaceous glands)
- Keratin is the most abundant protein in dead epidermal structures like hair and nails. (False: it's melanin)
- Sebum is composed of an oily mixture of lipids and cell fragments. (True)
- The observable part of a hair is called the shaft, not the root. (False)
- The mechanical strength of the skin is attributed to the dermis, not the epidermis. (False)
