Connective Tissue Flashcards
Functions of connective tissue: (4)
Binds and supports body tissues together, protection, insulation, and transportation
What is extra cellular matrix?
Nonliving material that surrounds living cells that the cells made
Two main elements of matrix
Ground substance and fibers
Three types of fibers
Collagen, elastic, and reticular
Bone (occeous tissue) is composed of:
Bone cells in cavities, hard matrix of calcium salts, and large numbers of collagen fibers
What is the function of bone (occeous tissue)
Protect and support the body
Three types of cartilage tissue
Hyaline, elastic, and fibrocartilage
Most common cartilage
Hyaline
Hyaline cartilage is composed of
Abundant collagen fibers and rubbery matrix
Elastic cartilage provides:
Elasticity
Example of elastic cartilage
Supports the external ear
Fibrocartiliage is
Highly compressible
Example of fibrocartiliage
Forms cushion-like discs between vertebrae
Main matrix element of dense connective tissue
Collagen fibers
Fibroblasts are cells that make what
Collagen
Examples of dense regular tissues
Tendon and ligaments
Examples of dense irregular tissue
Skin
Three types of loose connective tissue
Areolar, adipose, and reticular
Most widely distributed connective tissue
Areolar tissue
Soft, pliable tissue
Areolar tissue
Contains all fiber types
Areolar tissue
Can soak up excess fluid
Areolar tissue
What tissue holds internal organs together
Areolar tissue
Adipose tissue is also known as what
Fat
What kind of tissue is matrix
Adipose
What tissue does oil occupy most of the fat cells volume
Adipose
Functions of adipose tissue
Insulates the body, protects some organs, and serves as a sight of fuel storage
What tissue is a delicate network of interwoven fibers
Reticular
What tissue forms stroma of lymphoid organs
Reticular
Examples of reticular tissue
Lymph nodes, spleen, and bone marrow
Blood cells are surrounded by what
Fluid matrix
In blood what is visible during clotting
Fibers
Blood tissue function
Transport vehicle for materials
Function of muscle tissue
Produce movement
Three types of muscle tissue
Skeletal, cardiac, and smooth
Which muscle tissue is controlled voluntary
Skeletal
Which muscle tissues are controlled involuntary
Cardiac and smooth
In Skeletal muscle tissues the cells are what
Striated
In skeletal muscle tissue cells have more than one
Nucleus
Cardiac muscle is only found in the
Heart
Cardiac muscle function
Pump blood
In Cardiac muscle tissue cells attached to other cardiac muscle cells at
Intercalated discs
In cardiac muscle cells, cells have more than one
Nucleus per cell
Smooth muscle surrounds
Hollow organs
Smooth muscle shows
No visible striations
Smooth muscles has one
Nucleus per cell
In nervous tissue what supports glical cells
Neurons and nerves
Nervous tissue function
Send impulses to other areas of the body
Where is nervous tissue found
Brain, spinal cord, and nerves
Two main functions for nervous tissue
Irritability and conductibility
