Histology Jackie Hernandez P.5
Epithelial Tissue
Stratified Cuboidal ET
function: Protection
Looks like an open pomegranate
Location: Lining of ducts or mammary glands, sweat glands, salivary glands & pancreas
Simple Cuboidal ET
Looks like chia seeds when they absorb water
Function: Protection & Secretion
Location: Surface of ovaries, linings of kidney tubules, & linings of ducts of certain glands
Simple Columnar ET
Function: Protection, secretion & absorption
Looks like a footprint or cantaloupe
Location: lining of uterus, stomach & intestine
Stratified Columnar ET
Looks like like a separated river with tadpoles
Function: Protection & secretion
Location:Male urethra, linings in large excretory glands
Pseudostratified Columnar ET
Function: Protection
Looks like caviar
Location: Passageways of respiratory system
Stratified Squamous ET
Function: Protection
Looks like waves crashing into each other
Location:Superficial layer of skin, linings of oral cavity, throat, vagina, & anal canal
Simple Squamous ET
Looks like tadpoles (baby frogs)
Function: Filtration, Diffusion, osmosis; covers surface
Location: Air sac lungs, wall of capillaries, lining of blood & lymph vessels, part of the membranes ling body cavities & covering viscera
Transitional ET
Looks like the ocean
Function: Prevents urine from diffusing back into internal environment
Location: Lining of urinary bladder, urethra, &uterus
Types of Membranes
Connective
Synovial Membranes
Line joints& are composed of connective tissue
Connective
Serous
Line cavities don't open to the outside
Exist as double layer membranes
Cutaneous
dry membrane that is keratinized for protection & waterproof
the skin
Mucous
Line cavities & tubes open outside body
Contain goblet cells
Include oral & nasal cavities & tublar organs
Connective Tissue
Blood
Location: Found all over body
General Characteristics: Red blood cells, white blood cells & platelets
Function: To transport substances throughout the body
Reticular
General Characteristics: Thin collagen fibers that for branching, supportive networks in a variety tissues
Function: Forms a frame work for certain internal organs
Location: Liver & Spleen
Adipose
Location: Under skin, between muscles, around kidneys & abdominal membranes & behind eyeballs
General characteristics: Only tissue to have fat droplet
Function: Cushion joints & organs, stores energy & insulates body
Dense
Location: Tendons, ligaments, deep layer of skin & scelra
General Characteristics: Densely packed collagen fibers & a network of elastic fibers
Function: Heals slowly
Hyaline Cartilage
Location: End of bones, nose & rings in the walls of the respiratory passages
General Characteristics: Fine collagen fibers in matrix: appears glossy
Function: Support & provides framework
Bone
General Characteristics: Matrix arranged in concentric circles around haversian canal
Function: Support, protection & shock absorption
Location: Bones of skeleton
Elastic Cartilage
Location: External ear & parts of the larynx
General characteristics: dense network & contains elastic fibers that make it flexible
Function: Supports, protects & provides flexible framework
Areolar/loose CT
General Characteristics: Forms thin, delicate membranes
Function: Protect & fill space
Location: Binds skin to underlying tissues, under most epithelial layers & between muscles
Fibrocartilage
General Characteristics: Lot of collagenous fibers that make the tissue tough
Function: Supports, protects, & provides frame work
Location:Between bony parts of spinal column, parts of pelvic girdle & knee
Muscular Tissue
Smooth
General Characteristics: Cannot be stimulated to contract with conscious effort
Function: Involuntary movements of internal organs
Location: Walls of hollow internal organs
Cardiac
General characteristics: Connected by intercalated discs
Function: Contraction for heart beats
Location: Heart muscle
Skeletal
General Characteristics: Cells are long and cylindrical
Function:Moves head, trunk & Limbs
Location: Muscles that attach to bones
Glands
Endocrine
Secrete into body fluids or blood
Exocrine
secrete products into ducts that open to body surface
Nervous Tissue
General Characteristics: Contains multiple signal pathways
Function: Coordinate & regulate body functions
Location: Brain , spinal cord & nerves
