Chapter 4 Flashcards
Are collections of cells of same type that perform a common function
Tissues
Study of tissue
Histology
Four major types of tissues:
Connective, muscle, nervous, and epithelial tissue
Connects and supports; other functions in more specialized tissues
Connective tissue
Specialized cells, ground substance, and protein fibers
Connective types
Ground substance + protein fibers =
Matrix
Stores fat
Adipose cells
Fills Spaces between cells and fibers
Ground substance
Branched and stretchable
Elastic fiber
Divides to produce other types of cells
Sterm cell
Unbranches, stern but flexible
Collagen fibers
Divides to produce other types of cells
Fibroblast
Branched, thin, and forms network
Reticular fiber
Engulfs pathogens or produces antibodies
White blood cell
Matrix is semisolid and contains collagen and elastin fibers
Fibroblasts
Includes areolar and reticular connective tissues and adipose tissue
Loose fibrous connective tissue
Found in ligaments and tendons
Dense fibrous connective tissue
Extracellular matrix is solid
Supportive connective tissue
Consists of formed elements and Plasma
Blood
Comes from tissue fluid; transported by lymphatic vessels to bloodstream
Lymph
Muscle tissue function
Provide movement
Specialized to contract or shorten
Fibers
3 types of muscle tissue
Skeletal, cardiac, and smooth
Striated and voluntary; connects to bones and skin
Characteristics of skeletal
Locations of skeletal
Widespread
Striated and involuntary; intercalated disks join cells
Characteristics of cardiac
