|
Epithelial Tissue
Simple Squamous |
Thin, flat, irregular (tiled cells, basal lamina, CT)
Delicate; found in protected regions where absorption takes place (e.g. alveoli); reduce friction |
|
|
Epithelial Tissue
Stratified Squamous |
Series of layers (superficial, stem cells, basal lamina, CT)
Tough; found where; keratinized to be water resistant (e.g. skin) or non-keratinized (e.g. oral cavity) |
|
|
Epithelial Tissue
Simple Cuboidal |
Hexagonal boxes with nucleus near center
Provide limited protection; occur where secretion and absorption take place (e.g. kidney tubules) |
|
|
Epithelial Tissue
Transitional |
Resemble stratified non-keratinized epithelium when stretched
Permits expansion and recoil after stretching (e.g. bladder) |
|
|
Epithelial Tissue
Simple Columnar |
Column-like cells bound to FT; modified with microvilli, goblet, cilia
Used for secretion, absorption (e.g. intestine), protection (e.g. stomach) |
|
|
Epithelial Tissue
Pseudostratified Ciliated Columnar (PSCC) |
Different sized columnar cells that appear to be stratified; apical membrane is ciliated
Used for protection (e.g. nasal cavity), secretion (e.g. male reproductive tract) |
|
|
Epithelial Tissue
Stratified Cuboidal |
Many layers of "cube"-like cells; lines some ducts (rare)
Used for protection, secretion and absorption |
|
|
Epithelial Tissue
Stratified Columnar |
Layers of rectangular shaped cells; no microvilli or cilia
Found in pharynx, epiglottis, anus, salivary gland ducts and urethra |
|
|
Connective Tissue
Mesenchyme |
Star shaped cells in thick fluid ground substance with collagen and reticular fibers
Found in developing embryo; precursor to all CT |
|
|
Connective Tissue
Areolar Tissue |
Least specialized CT; highly vascular; fibers (collagen, elastic and reticular) + cells (fibroblasts, macrophages, WBC's, adipocytes)
Support, strength, elasticity, cushioning (e.g. upper dermis) |
|
|
Connective Tissue
Adipose Tissue |
Modified areolar tissue; adipocytes + little matrix + blood vessels + lymphocytes
Cushioning, protection, energy reserve, insulation |
|
|
Connective Tissue
Reticular Tissue |
Few fibroblasts + interconnecting loose reticular fibers = loose meshwork
Supportive framework (stroma) within organs (e.g. spleen, liver, kidney) |
|
|
Connective Tissue
Dense Regular Connective Tissue |
Densely packed fibroblasts + well-organized collagen in parallel bundles; not very vascular
Attachment (e.g. tendon) |
|
|
Connective Tissue
Dense Irregular Connective Tissue |
Few fibroblasts + densely packed, unorganized collagen fibers in various directions
Protection, attachment, support (e.g. deep dermis) |
|
|
Connective Tissue
Elastic Connective Tissue |
Few fibroblasts + elastic fibers (bundled) + collagen fibers
Support, flexibility, joint movement (e.g. spinal ligaments) |
|
|
Connective Tissue
Hyaline Cartilage |
Chondroctes within lacunae; firm ground substance (chondrotin sulfate); no fibers
Support; flexibility; smooth movement at joints (e.g. rib, articular cartilage at end of long bones) |
|
|
Connective Tissue
Fibrocartilage |
Chondrocytes in lacunae surrounded by dense bundles of collagenous fibers and little ground substance
Support, fusion, shock absorption (e.g. intervertebral discs, pads of knee joint) |
|
|
Connective Tissue
Elastic Cartilage |
Chondrocytes in lacunae surrounded by elastic fibers and moderate ground subsance
Flexible support; maintains shape (e.g. external ear, epiglottis) |
|
|
Connective Tissue
Spongy (cancellous) Bone |
Osteocytes within lacunae in calcified matrix (osteoid + Ca salts); trabecular lattice with marrow cavities
Support, protection, mineral storage (e.g. epiphyses of long bones) |
|
|
Connective Tissue
Compact (dense) Bone |
Osteocytes within lacunae in calcified matrix in osteons/Haversian systems (lamellae + lacunae + caniculi); surrounded by periosteum
Support, protection, mineral storage (e.g. diaphyses of long bones) |
