Epithelial Membrane

Epithelial Membrane

Made up of Epithelial tissue

Cutaneous Membrane (Skin)

Has two layers Epidermis and Dermis

Mucous Membrane

Surface Epithelium resting on Areolar Tissue, lines the body cavities that open to the exterior

Serous Membrane

Composed of Simple Sqaumous Epithelium

Parietal Membrane

Outer membrane lining body cavity

Visceral Membrane

Inner Membrane lining body cavity

Serous Fluid

Thin clear fluid that separates serous layers

Peritoneum

The serous mebrane lining the abdominal cavity and covering its organs

Pleura

Each Pair of Serous Membranes lining the Thorax and enveloping lungs

Pericardium

Membrane enclosing the heart, consisting of outer fibrous layer & inner double layer of Serous Membrane

Synovial Membrane

Composed of Areolar Tissue and contain none Epithelial cells, & line Fibrous capsule surrounding the joints

Keratin

Fibrous protein that makes up Epidermis in a tough protective layer

Integumentary System

Skin and its Appendages (Sweat & Oil glands, hair, & nails

Cutaneous Sensory Receptors

Sensory Receptor found in the skin

Epidermis

Outer surface layer often kertainizied

Dermis

Made from Connective Tissue consists of two regions (Areolar Tissue on top, Fibrous Connective Tissue on bottom

Hypodermis (Subcutaneous tissue)

Fat tissue that anchors skin to underlying organs and is not part of the skin

Stratum Basale

Lies closest to Dermis, deepest layer of Epidermis, where skin is produced, goes through Mitosis & Daughter cells are pushed “Upward”

Stratum Germinativum

Also known as stratum Basale, is separated from the dermis by the basement membrane (basal lamina)

Stratum Lucidum

Outermost layer of Epidermis found in thick, hairless skin (Palms of hands & Soles of feet)

Stratum Corneum

Layer with Shingle like cells filled with Keratin (Epidermis) and dead cells

Melanin

A Dark Brown to Black pigment found in hair, skin, iris (Eye), responsible of for tanning of skin exposed to sunlight

Dermal Papillae

Uneven peg like projections from its superficial surface, indent Epidermis, have Capillary loops

Sebaceous Glands

Sweat Glands two Types

Sudoriferous Glands

Oil glands, duct empty hair follicles, lubricates skin, prevents brittle hair, kills bacteria, active during Puberty

Hair Follicle

Compound structure, inner Epithelial Sheath is composed to form the hair

Arrector Pilli

Small bands of Smooth Muscle, connect each hair follicle to the dermal tissue, when contracts creates “Goosebumps”

Lanula

Thickened Nail Matrix that appears as a White Crescent
