Tissues / Exam 2
| Question | Answer |
|---|---|
| What is Epithelial Tissue | -tightly packed cells -lack blood vessels -readily divide -one side is free and the other is attached at basement membrane -covers structures lines cavities |
| What is Simple tissue | composed of one layer of of cells |
| What is Stratified tissue | two or more layers cells |
| What is Cuboidal | square shaped cells |
| What is Squamous tissue | flattened cells |
| What is Columnar tissue | elongated cells |
| Types of Epithelial Tissues | 1. simple squamous 2. stratified squamous 3. simple cuboidal 4.stratified cuboidal 5.simple columnar 6.stratified columnar 7.pseudostratified columnar 8.transitional |
| What is Simple squamous | -one layer flattened cell -found in alveoli walls |
| What is Stratified squamous | -many layers of flattened cells ex. epidermis |
| What is Simple cuboidal | -one layer cubed cells Ex. kidney |
| What is Stratified cuboidal | -many layers cubed cells Ex. salvary glands |
| What is Simple columnar | -one layer elongated cells Ex. small intestines |
| What is Stratified columnar | -many layers of elongated cells Ex. male urethra |
| What is pseudostratified columnar | -appears layered but isn't -cells may be |
| What is Transitional | -layers and cells shapes depend on stretching bladder |
| What is Connective Tissue | -binds structures together -provides support and protection -stores fats -produces blood cells -cells separated by extracellular matrix (ECM)of organic chemicals and protein fibers |
| Cell Types | fibroblast macrophages mast cells |
| What is Fibroblast | make proteins fibers |
| What is Macrophages | large eating cells |
| What is Mast cells | release histamine associated with inflammation |
| What are the Four Types of Tissues | -epithelial tissue -connective tissue -nervous tissue -muscle tissues |
| What is Connective Tissue Fibers | -collagen -elastic -reticular |
| What is Collagen Fibers | strong but flexible |
| What is Elastic Fibers | stretchy but strong |
| What is Reticular Fibers | thin collagen fibers |
| Types of Connective Tissues | -loose CT tissue -Dense CT tissue -cartilage -bone -blood |
| Types of Loose Connective Tissue | -aveolar CT -adapose CT -venticular CT |
| What is Aveolar CT | -collagen and elastic fibers -between tissues |
| What is Adapose CT | -adapocytes store fat -beneath skin |
| What is Venticular CT | -venticular fibers -makes up walls of the spleen and liver |
| Types of Dense Connective Tissue | 1.regular dense CT 2.irregular dense CT |
| What is Regular Dense CT | -collagen fibers are parallel Ex.tendons and ligaments |
| What is Irregular Dense CT | -nonparallel collagen fibers Ex.dermis |
| Types of Cartilage | -hyaline -elastic -fibrocartilage - |
| What is Cartilage | -chondrocytes (cells) resides in lacunae (spaces) |
| What is Hyaline Cartilage | -collagen fibers Ex.at the ends of bones |
| What is Elastic Cartilage | -elastic fibers Ex.flap of ear |
| What is Fibrocartilage | -thick collagen fibers Ex.intervertebral discs |
| What are Bones | -osteocytes (cell) |
| Types of Bones | -compact -spongy |
| What is Compact Bone | -osteons -in skeleton |
| What is Spongy Bone | -contains red bone marrow -in skeleton |
| What is Blood | -cells -cells (white and red blood cells) -platelets -plasma -in vessels |
| What is Muscle Tissue | -muscle cells=fibers -50% of body is muscle tissue |
| Types of Muscle Tissue | -skeletal muscle -smooth muscle -cardiac muscle |
| What is Skeletal Muscle | -striated -voluntary -attached to skeleton |
| What is Smooth Muscle | -spindle-shaped cells -in walls of hallow organs -involuntary |
| What is Cardiac Muscle | -in heart -striated -intercalated disc connect cells -involuntary |
| What is Nervous Tissue | -found in brain, spinal cord, and nerves |
| Types of Cells in Nervous Tissue | -neurons -neuroglia |
| What is Grandular Epithelial Tissue | -1 or more cells that produce a product |
| Types of Grandular Epithelial Tissue | -endocrine glands -exocrine |
| What are Endocrine Glands | -secrete products that stay in the body |
| What is Exocrine | -secretion exits body |
| Types of Exocrine Glands | -merocrine -apocrine -holocrine |
| What is Merocrine | -secrete product only Ex.salivary glands |
| What is Apocrine | -secrete product and some cytoplasm Ex. mammory glands |
| What is Holocrine | -secrete product and entire cell (whole cell goes) Ex.ear wax gland |
| Types of Epithelial membranes | -mucous -serous -synovial -cutanous |
| What is Mucous Membrane | -line openings of the body and secrete thick mucous |
| What is Serous Membrane | -cover organs and line cavities -secrete thin serous fluid |
| What is Synovial Membrane | -line joint cavities -secrete synovial fluid for tube |
| What is Cutanous | -is skin |
