| The foundation layer of epithelial tissue | Basement membrane |
| Epithelial cells in a single layer | Simple epithelium |
| Epithelial cells in multiple layers | Stratefied epithelium |
| Epithelial tissue typically lacks | Blood vessels |
| Epithelial tissue always has a | Free ( exposed ) surface |
| Groups of cells that have a specialized function | Tissue |
| Number of major types of tissue | 4 |
| Epithelial cells that are taller than they are wide | Columnar epithelium |
| Epithelial cells that are about as wide as they are tall | Cuboidal epithelium |
| Columnar Epithelium | Nucleus is located near the base of the cell |
| Epithelium that appears to be in layers but all cells touch the basement membrane | Pseudostratfied epithelium |
| Epithelium that makes up membranes | Squamous epithelium |
| Epithelium that forms the epidermis ( outer layer of skin ) | Stratified squamous epithelium |
| Cuboidal Epithelium | Epithelium that forms the walls of ducts |
| Specilized cells that secrete mucus | Goblet cells |
| Hair-like structures found on the surface of some epithelium | Cilia |
| Formation of a dry, tough layer of squamous epithelium that is protective | Keratinization |
| Epithelial cells that change shape | Transitional epithelium |
| Glands that secrete into ducts | Exocrine glands |
| Glands that secrete directly into body fluids | Endocrine glands |
| Examples of merocrine glands | Salivary glands and sweat glands |
| Examples of apocrine glands | Mammary glands and ceruminous (ear wax ) glands |
| Example of Holocrine glands | Sebaceous glands |
| Most exocrine glands are | Merocrine glands |
| Merocrine glands typically secrete | A watery or mucus like fluid |
| Serous fluids are | Watery |
| Mucus is composed of a glycoprotein called | Mucin |
| Transitional epithelium is typically found in the | Urinary Bladder |
| The intercellular substance of connective tissue | Matrix |
| The matrix of connective tissue is composed of | fibers and ground substance |
| The most common "fixed" type of cell found in connective tissue | Fibroblasts |
| Phagocytic cells that start out as white blood cells | Macrophages |
| Cells that release heparin and histamine | Mast cells |
| Thick threads of protein | Collagen |
| Tendons and ligaments are composed of | Dense connective tissue |
| Elastic fibers are composed of the protein | Elastin |
| Loose connective tissue is also called | Areolar tissue |
| Fat tissue | Adipose tissue |
| Very thin collagenous fibers | Reticular fibers |
| Fibers that stretch easily | Elastic fibers |
| Contains a gel-like ground substance | Cartilage |
| The most common type of cartilage | Hyaline cartilage |
| Cartilage Cells | Chondrocytes |
| Where chondrocytes are located | Lacunae |
| The most rigid connective tissue | Bone |
| Bone cells | Osteocytes |
| Thin concentric layers of bone | Lamellae |
| Longitudinal channels found in bone that contains blood vessles | Osteonic ( Haversian ) canals |
| Connect osteocytes with the osteonic canals and other osteocytes | Canaliculi |
| Blood is a type of | Connective tissue |
| Skeletal muscle | Voluntary muscle |
| Smooth muscle | Involuntary muscle |
| Skeletal and cardiac muscle tissues are both | Striated muscle |
| Only found in the heart | Cardiac muscle |
| Spindle shaped muscle cells | Smooth muscle |
| Specialized intercellular junction found in cardiac muscle | Intercalated Disk |
| The branching pattern of cardiac muscle | Syncytium |
| Skeletal muscle has | multiple nuclei |
| Smooth muscle has | sincle nuclei |
| The basic or functional cells of the nervous system | Neuron |
| Cell that bind or connect nervous tissue together | Neuroglial Cells |
| Tissues found in the brain and spinal cord | Nervous tissues |
| Connective tissue that binds or connectes tissue layers together | Loose (areolar ) tissue |
