| Question | Answer |
|---|---|
| Peristalsis is the involuntary contraction and relaxation of the muscles of the digestive tract that assist in moving food and waste through. The muscles controlling peristalsis must be skeletal muscle. | False |
| The epidermis (outer layer of the skin) needs to be tough and resistant to shearing and stretching. What type of intercellular junction is best suited for this need? | Desmosome |
| What type of tissue is adipose tissue? | Connective tissue |
| Epithelial membranes are composed of what two tissue types? | Epithelium and underlying connective tissue |
| Which of the following organs contains smooth muscle in the wall? | Stomach |
| Which type of tissue lines the follicles of the thyroid glands? | Simple cuboidal epithelium |
| Researchers bred a generation of rats that were sterile. When investigating the cause for this change, they noticed that the The abnormal tissue was simple squamous epithelium. | False |
| The parotid gland produces a serous fluid (saliva) and dumps it into the nearby oral cavity. This makes the parotid gland an exocrine gland. | True |
| Which of the following is not one of the four basic types of body tissues? | Eye tissue |
| The membranes of the blood-brain barrier need to be fused, preventing any substances from entering and/or escaping between cells. What type of intercellular junction is best suited for this need? | Tight junction |
| Embryonic stem cells growing in a lab dish are bathed in a "cocktail" of chemicals that cause them to specialize into branching networks of single-nucleated cells that pulsate in unison. These cells are most likely part of what types of tissue? | Cardiac muscle |
| The lubricating fluid found between the walls of the thoracic cavity and the outside of the lungs are secreted by goblet cells. | False |
| Histology is the study of the history of anatomy and physiology. | False |
| The wall of the heart is made up of three layers with a middle layer that is responsible for the heart's pumping action. The three layers of the wall of the heart are all epithelial tissues. | False |
| Epithelial tissues do not have blood vessels. | True |
| Tendons and ligaments are composed primarily of what type of tissue? | Dense regular connective tissue |
| What characteristics would be found in the tissue that forms the inner lining of the respiratory passages? | Mucus-secreting, ciliated, and pseudostratified |
| What type of epithelium lines the urinary bladder and many of the urinary passageways? | Transitional epithelium |
| A particular tissue functions to direct the flow of a substance to an organ without losing any of the substance or letting any other substances come in contact with it. Tight junctions are most likely to be found between the cells of this tissue type. | True |
| Which of the following are found within areolar tissue? | Collagenous fibers, elastic fibers, and gel-like ground substance. |
| Which type of muscle tissue can be consciously controlled? | Skeletal muscle tissue |
| Tissues are groups of cells that have a common overall function, yet are distinctive in their characteristic cell types and the molecules that the cells produce. | True |
| What is the function of adipose tissue? | Stores energy |
| What is the long projection that extends from a neuron and serves as the primary means of transmitting electrical impulses or signals towards other neurons, muscle cells or glands called? | axon |
| The esophagus carries food from the mouth to the stomach. The inner lining is under constant friction as food passes through. What type of epithelial tissue would be best to protect the esophagus? | Stratified squamous epithelium |
| Spicy foods irritate the membrane of your mouth, which triggers goblet cells to produce a protective layer of a thick substance called mucus. What membrane must be lining the mouth? | Mucous membrane |
| What type of cell produces connective tissue fibers? | Fibroblast |
| In an epithelial tissue, what cell would secrete mucus to form a protective layer on the surface? | Goblet cells |
| Lacrimal glands release a watery solution, called tears, over the eye. What type of gland are lacrimal glands? | Merocrine gland |
| The greater omentum is a structure that exists in the abdomen and hangs over the digestive tract, behind the abdominal muscles.The tissue looks like it might be good for cushioning. What type of connective tissue is this? | Adipose tissue |
| What type of muscle tissue is in the walls of blood vessels? | Smooth muscle tissue |
| The smooth muscle cells of the digestive tract need to send electrical signals between each other to contract in unison. What type of intercellular junction is best suited for this need? | A gap junction |
| What is the primary characteristic of muscle tissues? | Ability to contract |
| Schwann cells are associated with neurons and are crucial to their function. They assist the neuron by speeding up the rate of signal transduction. Schwann cells are neuroglia. | True |
| The pyloric glands of the stomach release hydrochloric acid and other digestive juices during digestion. These glands have very short ducts and the tubes are branched. What kind of glands are pyloric glands? | Simple branched tubular glands |
| Which of the following is not true about the extracellular matrix? | It is the same in all of the tissues where it is found. |
| What type of muscle cell(s) have more than one nucleus? | Skeletal muscle cells only |
| What type of tissue contains striations but no intercalated discs? | Skeletal muscle tissue |
| A human embryo has a mutation that prevents smooth muscle from developing in the body. Which bodily functions will be most heavily affected by this mutation if the fetus survives to birth? | Digestive system functions |
| Which of the following best describes a characteristic of nervous tissue? | Some of its cells send electrochemical messages. |
| A serous membrane consists of which two tissue types? | Layer of simple squamous epithelium and a thin layer of areolar tissue. |
| Cardiac muscle can function without nervous stimulation but skeletal muscle cannot. | True |
| Which of the following cells respond to external stimuli by conducting electrical stimuli along long processes? | Neurons |
| Which of the following characteristics is used to name epithelial tissue types? | Organization of cells |
| A mucus-secreting goblet cell is a unicellular gland. | True |
| A synovial membrane is composed entirely of connective tissue. | True |
| Smooth muscle is voluntarily controlled. | False |
| Where can elastic connective tissue be found? | Walls of blood vessels |
| What type of tissue would be located between the blood and the air in the lungs to allow for gas exchange? | Simple squamous epithelium |
| What do intercellular junctions connect? | Cell membranes |
| What type of epithelium would be best suited for high rates of diffusion and filtration? | .. |
| What is the primary characteristic of muscle tissues? | Ability to contract |
| Which type of tissue lines the follicles of the thyroid glands? | Simple cuboidal epithelium |
| What are the functions of neuroglia? | They support and bind nervous tissue and provide nutrients and growth factors to neurons by connecting them to blood vessels. |
| The soft part of the nose and the supporting rings of the respiratory passages are composed of fibrocartilage. | False |
| What type of tissue is adipose tissue? | Connective tissue |
