Dense Regular Connective Tissue description and functionparallel 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 locationtendons, ligaments, aponeuroses
Dense Irregular Connective Tissue description and functionIrregularly 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 locationdermis of skin, submucosa of digestive tract, fibrous capsules of organs and joints
Hyaline Cartilage description and functionAmorphous but changeable matrix. Collagen fibers form matrix. Immature cells (chondoroblasts) produce matrix, mature cells (chondrocytes) located in lacunae. Supports and reinforces
Hyaline Cartilage locationforms most of embryonic skeleton. Covers ends of long bones, forms costal cartilages of ribs, cartilage of nose, trachea, and larynx
Elastic Cartilage description and functionlike hyaline cartilage but more elastic fibers in matrix (elastic fibers made by chondrocytes). Maintains the shape of a structure while allowing flexibility
Elastic Cartilage locationexternal ear and epiglotis
Bone description and functionhard, 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 locationskeletal bones
Cell that makes bony matrixOsteoblasts
Diaphysis structurecompact (dense)
Epiphysis Structurespongy
Lamellaeconcentric, ring-linke arrangement of bone tissue
Lacunaespace for osteocyte (mature bone cell)
Canaliculismall canals radiating in all directions from launae, allowing for communication between osteocytes
Haversian Canalcentral canal that contains blood vessels and nerves
Skeletal Muscle description and functionlong, cylindrical, multinucleated cells with striated appearance that are voluntary. voluntary movement, locamotion
Cardiac muscle description and functionbranching, striated appearance, uninucleated cells that connect at intercalated discs. involunatry propulsion of blood into the circulation of myocardium
Smooth Muscle description and functionspindle-shaped, non-striated cells with central nuclei. involutary propulsion of substances along internal passages
Smooth muscle cells contract what happens to blood vessels diameterconstrict
Nervous tissue description and functionneurons 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 locationbrain, spinal cord, nerves
