Histology Flashcards
What are the types of epithelial cells
Cuboidal, Columnar, Squamous
Where are Simple Cuboidal Epithelial Cells found? (Organ and body system)
Glands -Endocrine
Liver - Digestive
Most kidney tubules - urinary
Where are stratified cuboidal ET cells founds (organ and body system)?
Major glands: mammary, some sweat glands- Endocrine
Reproduction
Egg-producing vesicles (follicles) of ovaries
Sperm-producing tubules
What is the functions of Epithelial Tissue?
“Find Some APES”
Protection, Secretion, Excretion, Absorption, Filtration, Sensation
Where is simple Squamous ET cells found (organ - system)
Air Sacs - Respiratory
Serous membrane of stomach - Digestive
Kidney tubules - Urinary
Where is stratified squamous ET (non-keratinized and keratinized) located (organ - system)
Non-keratinized: tongue, oral mucosa, esophagus - digestive
Vagina - reproductive
Keratinized: Epidermis - Integumentary
Where is Simple Columnar ET located (organ - system)
Inner lining of stomach, intensities, gall bladder - Digestive
Uterus - reproductive
uterine tubules - urinary
Where are pseudostratified columnar ET cells located (organ-system)
Typically ciliated
Respiratory tract from nasal to bronchi - respiratory
Portions of male urethra - reproductive
Where are transitional ET located (organ - system)
bladder, ureter, part of urethra - Urinary
Where are goblet cells found, and what is their function?
In simple columnar and pseudostratified columnar epithelial
Produces protective mucous coating over mucous membrane
What if the function of simple cuboidal ET?
Secret/absorb/exchange
Hormone and spit
What is the function of stratified cuboidal ET?
Secretion
What is the function of simple columnar?
Absorb (nutrients)
Secrete (mucous, enzyme)
Exchange
What is the function of stratified columnar
Protect from internal pressure
What is the function of simple squamous ET?
Diffusion, filteration, secretion
What is the function of stratified squamous ET?
Non-keratinized: protects from abrasion (less waterproof, less strength)
Keratinized: protects from abrasion (waterproof, increase strength)
What is the function of transitional ET?
Ability to stretch
What is the function of pseudostratifed (ciliated) columnar ET?
Produce and move mucous
Name the types of CT with watery matrix
Reticular, Adipose, Areolar
Reticular CT: Location/system, Function, Fibers
Location: Lymph nodes, spleen, thalamus, bone marrow (lymphatic)
Function: Supportive Stromatolites (framework)
Fibers: Reticular
Areolar Tissue:
Location/System; Function; Fiber
Location: under ET, surrounding blood vessels
Esophagus, Trachea, Visceral layers of pericardium
Systems: Integumentary, Circulatory, Respiratory
Function: binds ET to deep tissue, allows passage of nerves/blood vessels; nutrients for ET
Fibers: Elastic, Collagenous, Reticular
Adipose - location/system, function, fibers
Location: subcutaneous fat, breast, surround kidney and eyes
System: Integumentary, reproductive, urinary
Function: energy, thermal regulation, cushion
Fibers: collagen
Dense Regular CT - location/system, function, fibers
Location - tendon, ligaments (muscular, skeletal)
Function - attachment
Fibers - collagen (all parallel)
Dense Irregular CT - location/system, function, fibers
Location - skin, submucosa of digestive tract, joints
System - Integumentary, skeletal, digestive
Function - (withstand multi-directional pull)
Fibers - collagen
Cartilage Types and cells
Hyaline - chondrocytes
Elastic - chondrocytes
Fibrocartilage - chondrocytes
Hyaline Cartilage - location/system, function, fibers
Location - costal, nose, end of bones / skeletal
Function - recoil / resist compression
Fibers - collagen
Elastic Cartilage Tissue - location/system, function, fiber
Location - ear, epiglottis / digestive
Function - maintain shape, flexible
Fiber - elastic
Fibrocartilage - location/system, function, fibers
Location - intervertebral disks
Function - recoil, bounce back, shock absorption
Fibers - collagen
Bone - Cells, Fibers, location, function
Osteoblasts, osteoclast, osteocytes
Structure, shape, protection
Bone
Collagen
Blood - cell, fiber, location, function
Cells - Red blood cells, white blood cells
Function - Transport gas
Location - Blood and bone
Fibers - Clotting fibers
Cells in Reticular CT
Fibroblast and white blood cells
Cells in Areolar CT
Immune cells (leukocytes), fibroblasts
Muscular MT - types and location
Skeletal - muscle
Cardiac - heart
Smooth - GI tract / hollow organs
Muscle with multiple nuclei
Skeletal
Muscle MT with only one nucleus
Smooth
what tissue has a Branched Cell Shape
Cardiac with intercalated disks
Muscles Tissue that is striated
Skeletal and Cardiac
