Longitudinal/Parallel | cutting from tip to tip/ banana split cut |
Oblique/ angle | used to determine what is seen under a microscope |
Histology | study of tissue |
Epithelial | covers surfaces, lines cavities and forms glands |
Connective | supports and forms framework of the body |
Muscle | contracts and produce movement |
Nervous | conducts nerve impulses |
Epithelial Tissue | forms a protective covering for the body, is the main tissue of the outter layer of skin,forms membranes,ducts, and the lining of body cavities and hollow organs |
Squamous | flat and irregular;vessels and alveoil of lungs |
Cuboidal | square, cube-shaped; pancreas and thyroid |
Columnar | long and narrow; stomach and uterine tubes |
Simple | single layer;thin barrier; easy for substances to pass through |
Stratified | many layers; |
Pseudostratified | looks like multiple layers but it is only one |
Transitional | changes size; bladder |
Functions of Epithelial Tissue | secretes mucas,traps foreign particles(cilia),repairs itself quickly |
Exocrine gland | secrete away from glands using ducts |
Endocrine gland | secrete directly into surrounding tissue fluid and into bloodstream, ductless |
Connective tissue | supporting fabric of the body,consists of cells surrounded by the matrix. |
Matrix | contains water,fibers and minerals. |
Generalized connective tissue | loose and dense |
Loose | soft and semiliquid |
Areolar tissue | most common type of conn. tissue,cells and fibers in soft jellylike matrix; |
Adipose tissue | contains adipose that store fat; insulates form heat loss;protective padding |
Dense | more firm and more fibers |
Irregular dense | mostly collagen fibers in random arrangement. membranes covering organs |
Regular dense | mostly collagen fibers in parallel alignment. tendons and ligaments |
Elastic | many elastic fibers for stretching |
Cartilage | avascular,strong,flexible absorbs shock,reduces friction at joints, |
hyaline cartilage | tough ends of long bones,tips of nose,larynx,trachea,fetal skeleton; |
fibrocartilage | firm,rigid, between vertebrae,knee joint; |
elastic cartilage | springs back, outer ear,larynx |
