• Endocrine
• Exocrine

• Secretes to Blood
• Often ductless

• Secrete onto surface or duct
• 1. Unicellular: goblet and mucous, GI and respiratory system, produce mucus
• 2. Mulicellular: usually surrounded by connective tissue, classified by structure and secretion mode

• Common origin (same part of embryo)
• varying vascularity 
• Extensive extracellular matrix

• Ground Substances-liquid and proteins
• Protein Fibers-proteins
• 1. Collagen: fibrous protein, cross-linked
• 2.Elastic: long, thin, networks, stretch and recoil
• 3. Reticular: network, hooked to collagen, example is basement membrane

• Each class of CT has its own cell
• Immature= blasts
• Mature=cytes
• White Blood Cells- immune
• Mast Cells-local inflammation allergies 
• Macrophages-scavengers

• Structure
• Transport
• Protect
• Support, surround, and interconnect others
• Store Energy
• Defense

• blood cells from hematopoietic stem cells
• Matrix: fluid (plasma) + proteins
• Transporter: function

• Chondroblasts and cytes
• collagen + significant ground substance 
• good at compression, smooth (end of bones)

• osteoblasts, cytes, and clasts (responsible for breakdown/recycling bones)
• collagen + salts
• remodeled, blood vascular

• Areolar – fibroblasts + significant
• Ground substance
• Stores H2O and salts (edema is the swelling of lymph)
• Widely distributed
• Superficial fasciaà example (just deep to skin;  hypodermis is a type of superficial fascia

• •Adipose – adipocytes, energy storage, insulation
• •Vascular – lots of blood vessels

•Reticular – fibroblasts 

•Reticular fibers- greater %

•Bone marrow, spleen

• Regular:
• 1.Fibroblasts
• 2.One fiber direction (don’t stretch)
• 3.Tendons, ligaments, deep fascia (around muscles; contain them)

• Irregular: 
• 1.Fibroblasts
• 2.Network of fibers (all directions, cross each other; resists pulling in
• multiple directions)
• 3.Skins Dermis, joint capsules, organ covers

• Membranes:epithelia and connective tissues
• 1.Cutaneous- skin/integumentary
• 2.Mucous-lining digestive/respiratory
• 3.Serous-line body cavities (ventral)
• 4.Synovial- around joints, connective
• tissue only

• 2.Fascia:framework
• a.Superficial –loose connective
• tissue
• b.Deep – dense connective tissue
• c.Subserous – loose
