Connective Tissue and cartilage chapter 4 Flashcards
Connective tissue function
Connects tissues and organs
Provides structure
Stores energy
Transport materials(blood)
Have no contact with enviroment
Connective tissue location
It forms all ligaments and tendons.
It’s also found throughout the body in fibrous membrane coverings.
Connective tissue characteristics
Specialized cells( adipocytes, erythrocytes, thrombocytes, osteocytes, leukocytes, chondrocytes, fibrocytes.
Solid extracellular protein fibers- elastic fibers, collagen fibers, and reticular fibers.
Fluid extracellular ground substance- gels, crystals, or semi solids.
Erythrocytes
Red blood cells
Leukocytes
White blood cells
Thrombocytes
Platelets
Fibroblasts
Found in all connective tissue proper.
Secretes proteins and hyalurinan(cellular cement)
Mast cells
Stimulate inflammation after injury or infection.
Release histamine and heparin.
Basophils are mast cells carried by blood.
Adipocytes
Fat cells
Each cell stores a single, large fat droplet,
Microphages
Phagocytic blood cells
Lymphocytes
Specialized immune cells
Osteocytes
Bone cells
Chondrocytes
Cartilage cells
Collagen fibers
Most common fibers in connective tissue proper
Long, straight, and unbranched
Strong and flexible
Resist force in one direction
Ex: tendons and ligaments
Reticular fibers
Network of interwoven fibers(stroma)
Strong and flexible
Resist force in many directions
Stabilize functional cells and structures
Ex: sheats around organs
Elastic fibers
Contain elastin
Branched and wavy
Return to original length after stretching
Ex: elastic ligaments of vertebrae
Ground substance
Fluid to make sure the fibers stay in place
Is clear, colorless and viscous
Fills spaces between cells and slows pathogen movement.
Areolar loos CT function
Bubble wrap for organs
Cushion, protection and packaging.
Areolar loose CT location
Around organs
Dermis of skin
Adipose tissue function
Shock absorption
Insulation
Cushion
Adipose tissue location
Skin, buttocks, eyes, breast, and abdominal areas.
Reticular tissue function
Forms the frame work of organs
Reticular tissue location
Liver, spleen, lymph nodes, and bone marrow.
Dense irregular CT function
Packaging, protection, support, flexibility, and stretch and recoil.
Dense irregular CT location
Dermis of skin and around organs.
Dense regular CT function
Strength to maintain stability.
Dense regular CT location
Ligaments, bone, cartilage and tendons.
Fibrocartilage function
Cushion, padding, and shock absorption.
Fibrocartilage location
Discs between vertebrae bone.
Hyaline cartilage function
Shock absorption, cushion and resilience.
Hyaline cartilage location
Joint cavities
Between ribs and sturnum
Around lung vanuels.
Elastic cartilage function
Stretch and recoil
Elastic cartilage location
Ear, nose, and epiglottis
Elastic tissue function
Stretch and recoil
Elastic tissue location
Vertebral column and around organs.
Blood function
Transport of nutrients, wastes, and gases like oxygen and carbon dioxide.
Blood location
Heart and blood vessels
Bone/osseous tissue function
Blood cell
Production
Support
Protection
Storage of calcium and movement.
Bone/ osseous tissue location
Head to toe.
Membranes
All membranes are formed by epithelial tissues and connective tissues.
Mucous membrane
Line passageway that have external connections
In digestive, respiratory, urinary and reproductive tract.
Ex: stomach and respiratory tract.
Serous membrane
Lines cavities not open to the outside
Are thin but strong
Have fluid transudate to reduce friction
Have a parietal portion covering the cavity
Have a visceral portion covering the organs
Cutaneous membrane
Is skin, surface of the body
Thick waterproof and dry
Synovial membrane
Line moving, articulating joint cavities
Produce synovial fluid(lubricant)
