A&P TISSUES chapter
| Question | Answer |
|---|---|
| Apical | exposed |
| Basal | attached |
| smooth muscle tissue | involuntary, uninucleate |
| cardiac muscle tissue | uninucleate, striated |
| skeletal muscle tissue | voluntary |
| canaliculi | osteocytes to canal |
| lamellae | rings of bone tissue surround canal |
| bone (osseous tissue) | organized around central canal |
| fibrocartilage | interwoven collagen fibers--found around joints, makes up vertebral discs and pubic symphysis |
| Adipocytes | fat cells |
| mesenchymal cells | stem cells |
| collagen fibers | straight, unbranched fibers strong and numerous in connective tissue proper. Make up tendons and ligaments |
| reticular fibers | branch and interconnect. Form supportive framework of fibers |
| Reticular tissue | contained in liver, kidneys, spleen, lymph nodes, and bone marrow. |
| Dense regular connective tissue | Tendons, ligaments, and aponeuroses(broad, flat tendons)--collagen fibers run parallel to one another, tightly packed |
| Dense irregular connective tissue | collagen fibers run in different directions. Located in dermis, around cartilage (perichondrium), and around bone and tough capsules around organs |
| elastic tissue | dense regular tissue dominated by elastic fibers. Found in walls of arteries, walls of lungs, and ligaments of vertebrae |
| cartilage cells | (chondrocytes) |
| Lacunae | enclosed in tiny chambers...belongs to cartilage cells |
| hyaline cartilage | most common. tightly packed collagen fibers. Found covering bone surfaces and synovial joints, larynx, trachae, bronchi, and between tips of ribs and sternum |
| elastic cartilage | external ear, auditory tract, and larynx. |
| alveolar/acinar | forms pockets...glandular cells |
| psuedostratified cilated columnar epithelium | lines respiratory tract and contains cilia (hair-like projections that sweep material over surface). Has goblet cells |
| Simple columnar | located in digestive tract organs. Microvilli- finger-like projections located at surface, thin, fuzzy layer increase surface area for absorption. Goblet cells rounded and scattered, secrete mucus |
| simple cubodial | found in thyroid gland, ducts and portions of kidney tubules |
| simple columnar | lines stomach and intestines |
