Chapter 4 Flashcards
What are the four major tissue types
Epithelial
Connective
Muscle
Nervous
Single layer of flat cells
Substances pass easily through
Mine air sacs blood vessels and lymphatic vessels
Characteristics of a simple squamous tissue cells
Single layer of cube shaped cells
Line kidney tubules and cover ovaries
Characteristics of simple cuboidal tissue cells
Single layer of elongated cells
Sometimes possess cilia or microvilli
Often have goblet cells
Line uterus stomach and intestines
Characteristics of Simple columnar tissues cells
Single layer of a elongated cells Nuclei at two or more levels Often have cilia Often have goblet cells Line respiratory passages
Characteristics of pseudostratified columnar tissue cells
Many flat layers Top cells are flat Can accumulate Keratin Outer layer of skin Line gross stuff
Characteristics Of stratified squamous tissue cells
2 to 3 layers
Cube shaped cells
Line ducts of mammory glands sweat glands and salivary glands and the pancreas
Characteristics of stratified cuboidal tissue cells
Layers of the longer that sells lower layer more cubed
Line part of male urethra and part of pharynx
Characteristics of stratified columnar tissue cells
Many cell layers
Round cells
Line parts of urinary bladder ureters and part of urethra
Characteristics of the transitional cell tissue
Close Space between cells; often fused
Located among cells that form lining
Characteristics of tight junctions
Tubular channels between cells
Located in cardiac muscle
Characteristics of a gap junctions
Form spot welds between cells
Located among outer skin cells
Characteristics of desmosomes
Fluid product
salivary glands
Pancreas
Sweat glands
Characteristics of merocrine glands
Cellular product
Portions of cytoplasm
Mammory glands
Ceruminous glands
Characteristics of apocrine glands
Secretory products
Whole cells
Sebaceous glands
Characteristics of holocrine glands
Bind structures Provide support and protection Serve as framework Fill Spaces Store fat Produce blood cells Protect against infections Help prepare tissue damage
General characteristics of connective tissue’s
Fixed cell
Most common cell
Large star shaped
Produce fibers
Characteristics of fibroblasts
Fixed cell
Release heparin
Release histamine
Characteristics of mast cells
Wandering cell
Phagocytic
Important in injury or infection
Characteristics of macrophages
Thick
Composed of collagen
Great tensile strength
Abundant in dense CT
Characteristics of collagenous fibers
Bundles of microfibrils Embedded in elastin
Elastic
Vocal cords air passages
Characteristics of elastic fibers
Very thin collagenous fibers
Highly branched
Form supportive networks
Reticular fibers
Rigid matrix
Chondrocytes in lacunae
Poor blood supply
Characteristics of cartilage
What are the three types of cartilage
Hyaline
Elastic
Fibrocartilage
Very tough and strong
Shock absorbency
Intervertebral discs
Pads of knees and pelvic girdle
Characteristics of fibrocartilage
Which types of muscles are involuntary
Smooth and cardiac
Which muscle type is not striated
Smooth muscle
What are the basic cells
Neurons
Carry information away from the body
Axon
Carry information to the cell body
Dendrite
