Cell/Tissue Questions All exchanges between cells and the blood are made through: other cells. interstitial fluid. air. lymph. water. All neurons receive and conduct _______ from one part of the body to another. hormones muscle signals chemical messages electrochemical messages radio signals Groups of cells that are similar in structure and function are called: multiple cells. tissues. epithelium. connective tissue. nervous tissue. Most connective tissues are well vascularized, meaning they have a good blood supply. Which of the following connective tissues represent an exception?
Dense irregular connective tissues Tendons and ligaments Bone Blood Loose areolar connective tissue Of the different types of muscle tissue only ______ is involuntary and contains intercalated discs. cardiac muscle visceral muscle skeletal muscle smooth muscle rough muscle The _______ scattered in the lipid bilayer are responsible for most of the specialized functions of the plasma membrane. phospholipids cholesterol proteins carbohydrates nucleic acids What does it mean to say that the plasma membrane is "selectively permeable"? It allows some substances to pass through it and keeps others out. It allows everything to enter but is selective about what leaves. It is selective about what enters but will allow everything to leave the cell. The membrane is selectively permeable only during the day. The membrane is selectively permeable only during the night.
Which of the following types of epithelial tissue usually forms membranes where filtration or exchange of substances by diffusion occurs? Simple squamous Simple cuboidal Simple columnar Pseudostratified columnar Stratified squamous Adipose tissue: contains large amounts of protein. functions as an insulator and protective tissue. exists in three forms: gelatinous, red, yellow. is composed of relatively small cells. contains large amounts of extracellular material. In an area where an epithelium is subjected to considerable wear and tear, you would expect to find: simple squamous epithelium. transitional epithelium. simple columnar epithelium. stratified squamous epithelium. simple cuboidal epithelium. In parts of the body, such as the urinary bladder, where considerable distension occurs, you can expect to find:

stratified columnar epithelium. dense fibrous connective tissue. transitional epithelium. elastic cartilage. simple cuboidal epithelium. Simple columnar epithelium can be found lining the: liver ducts. kidney ducts. small intestine. esophagus. arteries. The epithelium that lines a blood vessel is called: simple cuboidal epithelium. simple columnar epithelium. simple squamous epithelium. pseudostratified epithelium. transitional epithelium. The tissue that covers the body surfaces, lines its cavities and forms glands is the _______ tissue. muscle connective epithelial nervous blood Which statement best characterizes connective tissue?
Always arranged in a single layer of cells. Usually composed of a large amount of extracellular matter. Cells arranged in many strata. One surface exposed to the exterior of the body or to the interior of a hollow structure. Found connecting the brain to the spinal nerve cord.
