Vocab #5 Flashcards
Membranes composed of epithelial tissue with an underlying layer of connective tissue; covering and lining membranes
Epithelial membranes
The skin, composed of epidermal and Demerol layers
Cutaneous membrane
Membrane that forms the lining of body cavities open to exterior
Mucous membrane
A clear, water secreted by the cells of a serous membrane
Serous fluid
The serous membrane lining the interior of the abdominal cavity and covering the surfaces of the abdominal organs
Peritoneum
The serous membrane covering the lung and lining the thoracic cavity
Pleurae
Membrane sacs enveloping the heart
Pericardia
Composed of loose Areolar connective tissue; line the fibrous capsules surrounding joints
Synovial membrane
The skin and accessory organs
Integumentary system
The outer layer of the skin; an epithelium
Epidermis
Deeper layer of the skin, composed of dense irregular tissue
Dermis
Adipose tissue beneath the skin
Hypodermis
Tough, insoluble protein found in tissues such as hair, nails, and epidermis of the skin
Keratin
Cells contain thick bundles of intermediate filaments made of pre-keratin
Stratum spinosum
Cells are flattened, organelles are deteriorating; cytoplasm full of granules
Stratum granulosum
Cells die and form this clear layer
Stratum lucidum
Cells are dead, flat membranous sacs filled with keratin. Glycolipids in extracellular space make skin water resistant
Stratum corneum
Stem cells are actively dividing, some newly formed cells become part of the more superficial layer
Stratum basale
The dark pigment synthesized by melanocytes, responsible for skin color
Melanin
Important sentries that alert and activate immune system cells to a threat such as bacterial or viral invasion
Epidermal dendric cells
Superficial layer of dermis bordering epidermis contains dermal papillae the cause of fingerprints
Papillary layer
Cells associated with nerve endings that serve as touch receptors
Merkel cells
When blood supply is restricted these appear in dermis
Decubitus ulcers
A blush coloration of the mucous membranes and skin caused by deficient oxygenation of the blood
Cyanosis
Glands that empty their sebum secretion into hair follicles
Sebaceous glands
The oily secretion of sebaceous glands
Sebum
“Fast flowing sebum”, known as cradle cap in infants, is caused by overreacting of the sebaceous glands
Seborrhea
The glands that produce a salinc solution called sweat
Sudoriferous glands
Deep layer of the dermis, contains hair follicles, sweat glands, sebaceous glands and highly vascular
Reticular layer
Peg like like projections; indent the epidermis
Dermal papillae
