Tissues & Membranes
A&P chpt4
Term | Definition |
---|---|
dense fibrous connective tissue | tissue in tendons & ligaments |
smooth muscle | found in walls of hollow body organs |
blood | only connective tissue with liquid matrix |
elastic connective tissue | closely packed elastic fibers |
erythrocytes | red blood cells |
leukocytes | white blood cells |
cardiac muscle | found only in wall of heart |
nervous tissue | found in brain, spinal chord & nerves |
inflammation | nonspecific defense mechanism that attempts to localize or contain tissue energy & to prepare the area for healing |
regeneration & fibrosis | 2 types of tissue repair |
fibrosis | replacement of destroyed tissue by the generation of fibrous connective tissue |
fibrosis | formation of scar tissue |
peritoneum | serous membrane in the abdominopelvic cavity |
tissue | group of cells, similar structure & function together as a unit |
basement membrane | epithelial tissue, opposite the free surface the cells are attached to underlying connective tissue by a non cellular |
simple cuboidal epithelium | single layer cube shaped, covering of ovary, lining of kidney tubules |
goblet cells | interspersed amoung simple columnar cells |
goblet cells | flask shaped, secrete mucus |
thrombocytes | blood platelets |
neurons or nerve cells | cells in nerve tissue that generate & connect impulses |
serous membrane | epithelial membrane that secretes a serous fluid, lines the closed body cavities & covers the organs within those cavities |
serous membrane | also called serosa |
pericardium | serous membrane lines the pericardial cavity & covers the heart |
epithelial, connective, muscle & nervous | 4 types of tissue |
simple columnar epithelium | single layer of cells that are taller than they are wide, lining stomach & intestines |
pleura | serous membrane lines thoracic cavity & covers the lungs |
adipose tissue | fat connective tissue |
tendons | connects muscles to bone |
ligaments | connects bones to bones |
cartilage | connective tissue, solid yet flexible |
bone | osseous tissue, most rigid of all connective tissue |
regeneration | replacement of destroyed tissue by the proliferation of cells that are identical to the original cells |
simple squamous epithelium | single layer, thin flat cells |
elastic cartilage | flexible cartilage |
hyaline cartilage | most common type of cartilage, connects ribs to sternum, supports rings of trachea |
skeletal muscle | typical "muscle" |
skeletal muscle | 40% of body weight |
meninges | connective tissue membranes in dorsal cavity that covers or protects the brain & spinal chord |
stratified squamous epithelium | consists of many layers, forms outer layer of skin & extends a short distance into every body opening that is continuous with the skin |
epithelial tissue | widespread throughout the body, forms covering of all body surfaces, lines body cavities & hollow organs |
epithelial tissue | major tissue in glands |
muscle tissue | composed of cells that have special ability to shorten or contract |
fibro cartilage | connective tissue has an abundance of strong collagenous fibers embedded in the matrix |
synovial membranes | secrete synovial fluid into the joint cavity |
synovial membranes | fluid in it lubricates the cartilage on the ends of the bones so they can move freely & without friction |
connective tissue | binds structures together |
loose connective tissue | packing material in the body |
serous fluid | secreted by the epithelium, lubricates the membrane & reduces friction & abrasion when the organs in the thoracic or abdominopelvic cavity move against each other or the cavity wall |
body membranes | thin sheets of tissue that cover the body, line body cavities, cover organs within the cavities & line the cavities in hollow organs |
mucous membranes | epithelial membranes that consist of epithelial tissue attached to underlying loose connective tissue |
glandular epithelium | consists of cells that are specialized to produce & secrete substances |
transitional epithelium | specialized type of tissue that has several layers but can be stretched in response to tension |
