Secrete products by exocytosis
Accumulates products then ruputures
Accumulates products but only ruptures at the apex
Goblet cells
Found in simple columnar epithelium and pseudostratified columnar epithelium
Intercalated discs
found in Cardiac Muscle tissue
Where would you find macrophages? (loose connective tissue)
Areolar and reticular CT
White fat
Used for nutrient storage, shock absorption, insulations, and energy storage
Brown fat
Used to heat bloodstream and body
Hyaline cartilage
Found in the ends of long bones
Elastic Cartilage
Found in ears and epiglottis
Strong and able to absorb impact found in intervertebral discs and knee
Tissues with extremely well regenerative capacity
Epithelial tissue, bone, areolar, dense irregular, and blood forming tissue
Tissues with moderate regenerative capacity
Smooth muscle and dense regular
Tissues with no regenerative capacity
Cardiac muscle and nervous tissue
Examples of connective tissue
Areolar, adipose, reticular, dense regular, dense irregular, elastic CT, hyaline, fibrocartilage, elastic cartilage, bone, and blood
What would you find in a bone?
Osteoblasts, Hematopoietic stem cells, collagen, inorganic calcium slats, osteocytes (MAINTAIN MATRIX IN THE BONE), lacunae, and osteons
Found in CT proper
Found in cartilage
found in bone
help increase surface area in epithelial cells (places of absorption)
help move things across a cell (like mucous)
What connective tissue elements makes up the extracellular matrix?
Ground substance and fibers
Simple squamous epithelium (location and function)
Found in air sacs of lungs and are involved in absorption, secretion, and filtration processes
Simple cuboidal epithelium (location and function)
Found in Kidney tubules and are involved in secretion and absorption
Simple columnar epithelium (location and function)
Found in digestive tract, gallbladder, ducts of some glands, bronchi, and uterine tubes. Are involved in absorption and secretion of mucus, enzymes, and other substances
What type of cells will you see in Areolar CT?
Fibroblasts, macrophages, fat cells, and some white blood cells
Main function of epithelial tissue
Protections, absorption, filtration, excretions, secretion, sensory reception
Collagen Fibers
Strongest and most abundant fiber, provides high tensile strength
Elastic Fibers
Network of long thin elastic fibers that stretch and recoil
Reticular Fibers
Short, fine, and highly branched collagenous fibers
Steps in preparing tissue to be viewed under a microscope
1. fixed and preserved with a solvent 2. cut into thin slices to transmit light or electrons 3. stained to enhance contrast
A group of cells similar in stricture that perform common or related functions
The study of tissues
Endocrine glands
Secrete internally (EX hormones), ductless, and travel through bloodstream
Exocrine glands
Secrete on body surface and cavities through ducts
Steps in tissue repair
1. Inflammation (blood vessels dilate, blood clotting occurs) 2. Organization (blood clot is replaced with granulation tissue, debris is phagocytized, fibroblasts produce collagen fibers to bridge gap, and the epithelium begins to regenerate) 3. Regeneration (the scab detaches, fibrous tissue matures, epithelium thickens to resemble nearby tissue, ends in regenerated epithelium with underlying scar tissue)
Main components of CT
Interstitial fluid, cell adhesion proteins, proteoglycans, water
Main job of Connective Tissue
Support, protections, binding of tissues
Cardiac muscle
Involuntary and found in the heart
Skeletal muscle
Voluntary and found attached to bones
Smooth muscle
Involuntary and found in hollow organs
Cutaneous membrane
SKIN, a dry membrane
Mucous membrane
also called mucosae, lines body cavities that are open to the exterior (EX respiratory, urogenital, and digestive), moist membrane, epithelial sheet lies over layer of loose connective tissue called LAMINA PROPRIA, may secrete mucus
Serous membrane
Also called serosae and found in ventral cavities. Made from simple squamous epithelium (mesothelium) resting on areolar CT. PARIETAL serosae lines internal body cavity walls while VISCERAL covers internal organs. moist membranes. Pleurae - lungs Pericardium - heart Peritoneum - abdomen
All connective tissues arise from this as their origin
Keratinized stratified squamous epithelium
Found in skin, nonkeratinized are found in moist linings
Primary tissues
Epithelial, Connective, Muscle, Nervous
What makes up myofilaments?
Actin and Myosin, they help contract muscles
Membrane linings and coverings are composed of what 2 tissues?
Epithelial and CT Proper tissues
Apical surface
Top surface, used to define stratified epitheliums
Basal surface
Bottom layer
Histology tree

serous membranes in the ventral body cavities
lining of lymphatic vessels, blood vessels, and heart
How do you define a stratified epithelium?
By the apical surface
Categorize structure of glands
