connective tissues Flashcards
Functions on connective tissue
Bonds body tissues together
Supports body
Protects
characteristics of connective tissue
Found everywhere in body
Includes most abundant and widely distributed tissues
Variations in blood supply
Some are well vascularized
Some have poor blood supply or are avascular
Define Extracellular matrix
Nonliving material that surrounds living cells
Define Ground substance
Mostly water along with adhesion proteins
Define Fibers
Produced by the cells
Name Three types of fibers
Collagen, elastic and reticular
Name Types of connective tissues
Bone Hyaline Elastic Fibrocartilage Dense Areolar Adipose Reticular Blood
Describe and name functions of Bone
Composed of bone cells in lacunae, hard matrix of calcium salts, and large # of collagen fibers
Used to protect and support the body
Describe, name function and location of Hyaline cartilage
Most common cartilage
Composed of abundant collagen fibers, rubbery matrix
Entire fetal skeleton is hyaline cartilage
Name function and location of Elastic cartilage
Provides elasticity
Supports external ear
Describe, name location and function of Fibrocartilage
Highly compressible
Forms cushion like disks between vertebrae
Describe Dense Connective tissue
Main matrix element is collagen fibers
Cells are fibroblasts
Examples - tendon (attach muscle to bone) and ligaments (attach bone to bone)
Describe, name function and location of Adipose connective tissue
Matrix is an areolar tissue where fat globules are
Many cells contain large lipid deposits
Functions- insulates, protects, and site of fuel storage
Describe, name location example of Reticular connective tissue
Delicate network of interwoven fibers Forms stroma (internal supporting network) of lymphoid organs Ex - lymph nodes, spleen , bone marrow
Describe, name function of Blood
Blood cells surrounded by fluid matrix
Fibers are visible during clotting
Functions as the transport vehicle for materials
Describe, name function and location of Areolar connective tissue
Most widely distributed connective tissue
Soft, pliable tissue
Contains all fiber types
Can soak up excess fluid
Coordinates, regulates and integrates body functions
Nervous tissue
Contains intercalated disk
Cardiac muscle
Muscle that lacks striations
Smooth muscle
Striated and involuntary
Cardiac muscle
Striated and voluntary
Skeletal muscle
Contains neurons and neuroglial cells
Nervous tissue
Muscle attached to bones
Skeletal muscle
