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 |
