Updated.
compound microscope - Answer microscope used in lab, with 2 sets of magnifying lenses
oculars and objective - Answer the sets of magnifying lenses in a compound microscope
ocular lenses - Answer 10x, bring image into focus of eye
objective lenses - Answer 4x-100x, closest to object, located on rotating nosepiece, collect
light from sample
coaxial stage control - Answer on the side of the microscope, moves slide in 4 directions
light source - Answer illuminates specimen, controls light intensity, located on base of
microscope
iris diaphragm - Answer located beneath condenser, adjusts contrast and lighting
hold by arm and base - Answer how to properly move microscope
4x/scanning - Answer what objective do you start with
epithelia characteristics - Answer free apical, fixed basal, specific intracellular junction,
basement membrane, avascular, sensory nerve ending, fast regeneration
epithelia functions - Answer resist dehydration/injury, secretion, monitor environment,
regulate permeability
transitional epithelia - Answer stratified, transition from cuboidal to squamous in urinary
tract
pseudostratified - Answer in trachea, all cells contact basal lamina but not all reach apical
surface, nuclei appear on top of each other, can be ciliated
,cilia - Answer fingerlike, motile projections in simple columnar
microvilli - Answer nonmotile, increase surface area, in digestive and urinary tract
simple cuboidal - Answer collecting duct of kidney tissue type
nonkeratinized - Answer stratified squamous is keratinized/nonkeratinized
apical surface - Answer define epithelial cell shape by shape of cells at ______
keratinized stratified squamous - Answer skin tissue type
ocular micrometer - Answer measuring guide in ocular lens
connective tissue - Answer diverse, abundant, widely distributed throughout the body
structural support, fat storage, exchange of nutrients and metabolic waste, defense, protection -
Answer connective tissue functions
CT proper, supporting, fluid - Answer connective tissue broken into
loose and dense - Answer CT prober broken into
loose CT - Answer abundant ground substance, scattered cells, and loosely arranged protein
fibers
dense CT - Answer abundant, tightly packed fibers with few cells, less ground substance
areolar, adipose reticular - Answer types of loose connective tissue
areolar - Answer
adipose - Answer
reticular - Answer
, cartilage and bone - Answer types of supporting connective tissue
dense regular - Answer
dense irregular - Answer
dense regular - Answer found in tendons and ligaments, densely packed, parallel collagen
fibers, fibroblasts between layers, little ground substance
dense irregular - Answer dermis, periosteum, perichondrium, and capsule of organs,
composed of randomly arranged collagen fibers and fibroblasts between layers, more ground
substance
dense elastic tissue - Answer in the walls of elastic arteries, trachea, bronchi, and vocal cords,
composed of branching elastic fibers with fibroblasts between layers
regular, irregular, elastic - Answer types of dense connective tissue
cartilage - Answer semisolid extracellular matrix, allows flexibility (supporting CT)
bone - Answer solid, more rigid, more support (supporting CT)
hyaline cartilage, elastic cartilage, fibrocartilage - Answer types of cartilage
hyaline cartilage - Answer
elastic cartilage - Answer
fibrocartilage - Answer
elastic cartilage - Answer found in external ear and epiglottis, contains abundant elastic fibers
around lacunae that contain chondrocytes, perichondrium
hyaline cartilage - Answer found in larynx, trachea, and nose, chondrocytes in lacunae
scattered in matrix, collagen fibers, perichondrium
