tissue
specialized cells similar in structure and function
4 types of tissue
Epithelial tissue, Endothelium, Mesothelium, Connective Tissue
Epithelial tissue or Epithelium
covers internal/external body surfaces in variety of arrangements
Endothelium
cellular covering that forms lining of internal organs/blood vessels
Mesothelium
cellular covering that forms lining of serous membranes
ex peritoneum
Connective Tissue
adds support/structure to the body by holding the organs in place/binds body parts together
ex Adipose or fat
Muscle tissue (and 3 types)
contains cell material with ability to contract/ relax.
(skeletal, smooth, and cardiac)
Nervous tissue
cells with ability to react to stimuli and conduct electrical impulses
anaplasia
Change in structure in cells/orientation to each other
aplasia
lack of development of organ, tissue, or cell
Dysplasia
abnormal growth or development of organ, tissue or cell
Hyperplasia
abnormal increase in the number of normal cells in organ tissue or cell
Neoplasia
abnormal new growth of tissue, where multiplication of cells is uncontrolled and more rapid than normal
Atrophy
decrease in size or wasting of organ, tissue, or cell
Dystrophy
defective growth in size of organ tissue or cell
Hypertrophy
increase in size of organ tissue or cell
Exocrine glands
cell groups that secrete chemical substances in to ducts that lead out of the body or organ
Endocrine glands
cell groups that secrete chemical substances directly into bloodstream
Organ
part of the body that performs special fuction(s)
hypoplasia
incomplete or less than normal development in organ tissue or cell
benign tumor
