 | Term | Definition |
| |
Dense Regular Connective Tissue description and function |
parallel collagen fibers with a few elastin fibers. Major cell type . os fibroblast. Bone to bone, muscle to muscle, muscle to bone attachments |
| |
Dense Regular Connective Tissue location |
tendons, ligaments, aponeuroses |
| |
Dense Irregular Connective Tissue description and function |
Irregularly arranged collagen fibers with some elastin fibers. Major cell type is fibroblast. Able to withstand tension exerted in many directions, provides structural strength |
| |
Dense Irregular Connective Tissue location |
dermis of skin, submucosa of digestive tract, fibrous capsules of organs and joints |
| |
Hyaline Cartilage description and function |
Amorphous but changeable matrix. Collagen fibers form matrix. Immature cells (chondoroblasts) produce matrix, mature cells (chondrocytes) located in lacunae. Supports and reinforces |
| |
Hyaline Cartilage location |
forms most of embryonic skeleton. Covers ends of long bones, forms costal cartilages of ribs, cartilage of nose, trachea, and larynx |
| |
Elastic Cartilage description and function |
like hyaline cartilage but more elastic fibers in matrix (elastic fibers made by chondrocytes). Maintains the shape of a structure while allowing flexibility |
| |
Elastic Cartilage location |
external ear and epiglotis |
| |
Bone description and function |
hard, calcified matrix containing many collagen fibers. Bone supports body and protects the organs, provides levers for muscles to act on, stores calcium, fat, and other minerals. Marrow is site of blood cell formation |
| |
Bone location |
skeletal bones |
| |
Cell that makes bony matrix |
Osteoblasts |
| |
Diaphysis structure |
compact (dense) |
| |
Epiphysis Structure |
spongy |
| |
Lamellae |
concentric, ring-linke arrangement of bone tissue |
| |
Lacunae |
space for osteocyte (mature bone cell) |
| |
Canaliculi |
small canals radiating in all directions from launae, allowing for communication between osteocytes |
| |
Haversian Canal |
central canal that contains blood vessels and nerves |
| |
Skeletal Muscle description and function |
long, cylindrical, multinucleated cells with striated appearance that are voluntary. voluntary movement, locamotion |
| |
Cardiac muscle description and function |
branching, striated appearance, uninucleated cells that connect at intercalated discs. involunatry propulsion of blood into the circulation of myocardium |
| |
Smooth Muscle description and function |
spindle-shaped, non-striated cells with central nuclei. involutary propulsion of substances along internal passages |
| |
Smooth muscle cells contract what happens to blood vessels diameter |
constrict |
| |
Nervous tissue description and function |
neurons are branches cells. Transmission of electrical signals from sensory receptors. Control of effectors through the transmission of electrical signals to muscles and glands |
| |
Nervous tissue location |
brain, spinal cord, nerves |
