| Question | Answer |
|---|---|
| An arrangement of epithelial cells in a single layer | simple epithelium |
| epithelial cells are layered one on another | stratified epithelium |
| a unique arrangement of differing cell shapes in a stratified, or layered, epithelial sheet | Transitional epithelium |
| only one layer of flat, scalelike cells | Simple squamous epithelium |
| composes the surface of the mucous membrane that lines the stomach, intestine, uterus, uterine tubes, and parts of the respiratory tract | Simple columnar epithelium |
| large, secretory vesicles that give them the appearance of a goblet | Goblet cells |
| composed of one layer of cuboidal cells resting on a basement membrane | Simple cuboidal epithelium |
| multiple layers of columnar cells, with only the most superficial cells being obviously columnar in appearance | Stratified columnar epithelium |
| Usually present in the greatest numbers in loose fibrous connective tissue, and macrophages are second | Fibroblasts |
| The subdural (“under the dura”) space is between the dura mater and arachnoid mater. The subdural space is normally only a potential space—but it can be-come a real space if blood leaks into it, forming a subdural hematoma. | Subdural space. |
| As its name suggests, the subarachnoid space is under the arachnoid and outside the pia ma-ter. This space contains a significant amount of cerebrospinal fluid (CSF) | Subarachnoid space. |
| Many nerve roots extending from the conus medullaris form a sort of “horse tail” of spinal nerve roots | cauda equina |
| A reflex consists of either a muscle contraction or a | glandular secretion. |
| Tongue movement is controlled by which cranial nerve? | hypoglossal |
| Mixed cranial nerves contain axons of | cerebral localization. |
| Unique in that it does not contain ribosomes, mitochondria, and other organelles typical of most body cells. Instead, the primary component of each RBC is the red protein pigment, hemoglobin (Hb) | erythrocyte |
| a thin white layer of leukocytes and platelets, is present at the interface be-tween the packed red cells and plasma. | buffy coat |
| Platelets play an important role in | blood clotting. |
| A decrease in the amount of white blood cells is called | leukopenia. |
| A type of abnormal heart sound that may signify incomplete closing of the valves is | a heart murmur. |
| Mechanical devices that permit the flow of blood in one direction only are called | valves. |
| Oxygen enters blood from alveolar air because the partial pressure of alveolar air is | greater than the partial pressure of incoming blood. |
| When carbon dioxide dissolves in water, some of the carbon dioxide molecules associate with water to form | carbonic acid. |
