 Histology | Study of Tissue |
| Epithelial Tissue | Protective linings |
| Connective Tissue | Supportive, bone, cartilage, etc. |
| Muscular | Contract |
| Nervous | Transmit information |
| Characteristic of Epithelial Tissue | tightly packed mosaics, covers external surface |
| Squamous | flat cells (ex. blood cells) |
| cuboidal | square shaped cells (ex. secretary) |
| columnar | elongated cells (ex. linings of nasal cavity, bronchi) |
| Simple | one layer of cells |
| stratified | multiple layers of cells |
| epithelial tissue proper | Skin, internal continuous linings |
| Mesothelial Tissue | Specialized type of epithelial tissue; lines cavities (2 pleural/ lungs, 1 pericardial/ heart, 1 peritoneal/ abdominal); slippery and smooth for ease of motion |
| Endothelial Tissue | lines blood/ lymph vessels, made up of smooth squamous cells |
| Connective Tissue | connect structures together, support body, contain a lot of intercelluar substance (matrix) |
| Matrix | intercelluar substance |
| Connective Tissue Divisions | loose, Dense, Special |
| Areolar Tissue | very loose tissue, irregular network of fibers, commonly found below the skin and between muscles and organs, binds things together, loose connective tissue |
| adipose Tissue | high concentration of fat cells, found in subcutaneous fascia, nucleus on cell wall, spherical "signet ring" shape, loose connective tissue |
| Tendon tissue | tough, nonelastic chords, made of densely packed parallel fibers, connect bone to muscle, dense connective tissue |
| aponeurosis | wide sheets of tendons |
| ligaments | connect bone to cartilage, tight parallel fibers, more elastic than tendons, dense connective tissue |
| fascia | bundle muscles int groups, spider-webby network that holds body together, dense connective tissue |
| subcutaneous fascia | continuous sheet around the whole body |
| Hyaline Cartilage | bluish white, translucent cartilage, covers articular surface of joints, forms framework of lower respiratory system, special connective tissue |
| elastic cartilage | bubbly looking cells, yellowish opaque color, rubbery, found in Ear (External auditory meatus, Eustacian tube), and Epiglotis, special connective tissue |
| fibrocartilage of intervetebral disc | found between vertebrae, collagenous fibers with cartilage cells, special connective tissue |
| chondroblasts | early cartilage cells, become cartilage cells |
| chondrocytes | cartilage cells |
| osteocytes | bone cells |
| osteoblasts | early bone cells, become bone cells |
| yellow bone marrow | makes fat and adapose tissue |
| red marrow | makes blood cells |
| aplastic anemia | deficiency in red blood cells |
| Dense/ Compact Bone (Osseous) Tissue | forms the cortex of bones, has lamellae, haversian canals, lacunae, and canaliculi, bone (osseous) tissue |
| Spongy/ cancellous bone(osseous) tissue | forms the interior of the bone, trabeculae, bone marrow, bone (osseous) tissue |
| haversian canal | circular canal within bone tissue that contains blood vessels and nerves |
| lamella | thin, sheetlike structures within bone tissue, form concentric circles |
| lacunae | hold bone cells in bone tissue |
| canaliculi | passages that connect lacunae to the haversian canal within bone tissue |
| condyle | rounded knuckle like process (bump) on a bone, elevation |
| crest | prominent ridge on a bone, elevation |
| process | bony prominence on a bone, elevation |
| head | enlargement on one end of a bone, beyond the neck, elevation |
| tubercle | small, rounded projection (bump) on a bone, elevation |
| fissure | cleft, deep groove on a bone, depression |
| fossa | pit or hollow on a bone, depression |
| foramen | hole in the bone, depression |
| groove | rut, thin furrow in a bone, depression |
| meatus | tube, passage way in a bone, depression |
| neck | constriction near the head of a bone, depression |
| sinus | cavity within a bone, depression |
| sulcus | moderately deep groove in a bone, depression |
| Joint | where two bones meet |
| synovial joint | highly moveable joint, ex. arm, knee |
| cartiliginous joint | limited mobility, ex between vertebrae |
| fiberous joint | no mobility, ex skull |
| striated (skeletal) | voluntary muscle, striped, multinuclear (ex biceps, abdominal, quadriceps) |
| smooth | autonomic muscle, mononuclear, nonstriated (ex. blood vessels, bronchial tubes, organs) |
| Cardiac | autonomic muscle, striated, mononuclear (ex. heart) |
| odontoid process | dens on which skull rotates |
| spinous process | sticks out back of vertebrae |
| transverse foramen | sticks out sides of vertebrae |
