Terms | Definitions |
|---|---|
Connective tissues (General) | cells secrete a matrix of protein fibers (collagen and/or elastin) |
Areolar (loose) | (connective) Cells: fibroblasts. Matrix:loose, irregular collagen and elastic network.Location/Function: found everywhere, universal packaging material, holds organs in place, holds tissues together |
Adipose (loose) | Cells: adipocytes each contains a large fat droplet) Matrix: small, irregular collagen Location/Function: fat tissue stores fat, insulates, padding |
Reticular (loose) | Cells:n/a Matrix: web like network of collagen house blood cells Location/Function: tissue in lymph nodes house White blood cells for body defense. Tissue in spleen filters out old/aging Red Blood Cells for recycling |
Dense Regular Fibrous | Cells:fibroblasts Matrix: dense parallel collagen fibers Location/Function: resistant to force in one direction, makes up tendons(attach. muscle to bone) and ligaments (bone to bone) |
Dense Irregular Fibrous | Cells:Fibroblasts Matrix: irregularly arranged collagen fibers Location/Function: resistant to force in multiple directions, found in areas stretched in multiple directions- skin, joint capsules |
Hyaline Cartilage | Cells: chondroblasts Matrix:hard, glassy Location/Function: covers joint surfaces, connects ribs to sternum, tracheal rings. Other types- Elastic (more elastin fibers, found in ears) and Fibrous (more collagen, found in intervertabral disks) |
Bone | Cells: osteoblasts Matrix: collagen mineralized w/ Ca, Mg, P Location/Function:cells are in lacuna (openings w/in matrix), cells are fed by fluid passing from blood vessels in the central canal through canaliculi, osteoclasts, breaks down bone tissue to reshape bones |
Blood | Cells: stem cells in red bone marrow divide into 1) erythrocytes(RBC's transport 02) 2) Leukocytes(WBC's-body defense) Matrix: plasma- the fibers are clotting proteins (fibrins) Location/Function: everywhere |
Muscle (General) | ability to contract, voluntary vs involuntary, found attached to bone, or in heart walls or lining hollow organs |
Skeletal | -striated-long, cylindrical cells with more than one nuclei, responsible for voluntary movement |
Cardiac | -striated-short cylindrical cells, branched, uninucleate cells, cells interconnect through intercalated disks which relay electrical impulses. Responsible for heart wall contractions |
Smooth | -non striated- short spindle, uninucleated cells, sheet forms walls of hollow organs, responsible for slow involuntary activities (digestive tract) |
Nervous | ectodermally derived nuerons support cells(glia) wich insulate and feed them, recieve stimuli, inte grate info send signals, brain spinal cord, all nerve bundles. |
