Question | Answer |
---|---|
study of tissue | histology |
4 types of tissue | epithelial, connective, muscle and neural |
epithelial tissue include what | it include epithelia cell and gland |
layer of cell that cover internal and external surface is | epithelia |
secreting cell derived from epithelia is | gland |
what are the 4 characteristics of epithelia? | cell are bound together, surface exposed to the environment, attached to basement membrane and avascular |
epithelial cell that produce secretion | gland cell |
secretion are discharge onto the surface of the skin are (sweat,milk) | exocrine |
secretion are release into the surrounding tissue and blood (hormone) | endocrine |
how epithelia is clasified? | it classified by the number of cell and the shape of the cell |
how many types of layers | 2 types of layers: simple and stratified |
how many cell shapes | 3 cell shapes: squamous, cuboidal and columnar |
single layer of cell covering a basement membrane | simple epithelium |
several layers of cell above the basement membrane | stratified epithelium |
appear a s fried egg, thin and flat | squamous epithelium |
resemble boxes or square, lie the center of each other and form a neat row | cuboidal epithelium |
cell are rectangular, tall and slender | columnar epithelium |
all cell contact the basement membrane, cell are not in row | pseudostratified epithelia |
can withstand a large amount of stretching | transitional epithelia. |
3 types of connective tissue | proper, fluid and supporting |
3 characteristic of connective tissue | specialized cell, protein fibers and ground substance. |
connective tissue fibers 3 of them | collagen, elastic and reticular fibers |
connective tissue fibers is form by what | fibroblasts |
what fill the space between cell and surround the connective tissue | ground substance |
is connective tissue exposed to the outside environment/ | no, it never exposed to the outside environment |
what are the 3 connective tissue proper? | fatty, tendons and lagaments |
what are the 2 fluid connective tissue | blood and lymph |
ehat are the 2 supporting connective tissue | bone and cartillage |
what are the 3 types of cartilage | hyaline, elastic-pinna and fibrocartilage |
connect ribs to the sternum cover bone and joint | hyaline |
between vertebra of the spinal colum | fibrocartilage |
what are the 4 membranes | mucous,serous,cuteneous and synovial |
lining cavities that comminicate with the exterior | mucous membrane |
line the sealed division of the ventral body cavity(pleura,pericardium and peritoneum) | serous membrane |
cover the surface of the body | cuteneous membrane |
lining for the fibrous capsule of articulation | synovial membrane |
what are the 3 types of muscles tissue | skeletal, smooth and cardiac |
skeletal | striated voluntary muscle |
cardiac | striated involuntary muscle |
smooth | nonstriated involuntary muscle |
produce a dense network of fibers known as | scar tissue |
study of disease | pathology |
rubor | redness |
atrophy | reduction in size of cell |
disuse atrophy | atrophy from immobilazation of a limb |
increase in size of cell of a tissue | hypertrophy |
accumulation of blood within a body tissue | hematoma |
tumor closely resembling their cell of origin | benign |
malignant tumor from connective tissue | sarcoma |
malignant neoplasm from epithelial | carcinoma |
benign tumor of fiberous tissue | fibroma |
localizez collection of pus | abscess |
difficult to swallowing | dysphagia |
increase in blood flow | hyperemia |
tumor composed of blood vessel | angioma |
benign tumor of a muscle | myoma |
rupture of a blodd vessel | hemmorrhage |
underlying cause of disease is unknown | idiopathic |
tumor an alteration of cell growth | neoplasia |
dolor | pain |
increase in the number of cell | hypertrophy |
tumor which invade and destroy adjacent structure | malignant |
major metastic route of carcinima | lymphatic spread |
epithelial tumor that project from the skin | polyp |
disease from a physician | iatrogenic |
when white blood cell invade an injury | phagocytosis |
interference of blood supply to an organ | ischemia |
nervous | direct immediate response,activities of organs system |
produce sex cell and hormones | reproduction |
eliminates excess water salt and waste | urinary |
process food and absorg nutrient | digestive |
deliver air to site where gas exchange | respiratory |
allow for locomotion, provide support, produce heat | muscular |
provide support, protect tissue, store mineral and form blood | skeletal |
defend against infection and disease | lymphatic |
transport cell and dissolve material | cardiovascular |
direct long term change in activities of other system | endocrine |
