Attaches skin to underlying tissues. Loose packing material of most organs and tissues, also known as stroma.
Loose Connective Tissue
Phagocytize or provide protection. Has 2 types: fixed and wandering.
Macrophages
Deepest portion of epidermis and a single layer. Cells become keratinized.
Statum Basale
Muscle that attaches to bones, moves the entire body. Striated and voluntary.
Skeletal Muscle
Tendons:Connects muscles to bones.
Ligaments:Connects bones to bones.
Has abundant collagen fibers that resist stretching.
Dense Regular Connective Tissue
Connection: holds cells together, forms a permeability barrier. 2 types: zonula adherens, zonula occludens.
Tight Junctions
Thin, clear zone, only found in palms and soles of feet.
Stratum Lucidum
Has all 5 layers in the epithelium, found on palms, fingertips, soles of feet. Fingerprints and footprints.
Thick Skin
Supporting Connective Tissue, elastic and collagen fibers, rigid but elastic properties.
Elastic Cartilage
Protein channels aid intercellula communication. Coordinate functions of cardiac and smooth muscle.
Gap Junctions
Most superficial and consists of cornified cells
Stratum Corneum
Provides protection against UV light. Group of chemicals derived from amino acid and tyrosine. Can be yellowish or reddish.
Melanin
Composed of collagen fibers and elastic fibers, able to stretch and recoil like a rubber band, found in vocal cords.
Dense Regular Elastic Connective Tissue
Common in some tissues (dermis of skin); rare in some (cartilage)
Adipose or Fat Cells
Limited cell division, cells shrink from where desmosones connect, lamellar bodies and additional keratin fibers form.
Stratum Spinosum
Superficial layer of the dermis, areolar with lots of elastic fibers.
Papillary
Supporting Connective Tissue, large amounts of collagen fibers, smooth surface. Is found in the trachea, ribs, nose and has some flexibility.
Hyaline Cartilage
Desmosomes
Name the 5 layers of the epidermis in order from deepest->superficial.
Stratum Basale, Stratum Spinosum, Stratum Granulosum, Stratum Lucidum, Stratum Corneum.
Muscle that causes hair to "stand up straight" or goospbumps.
