| Question | Answer |
|---|---|
| Many cerebral functions have typical locations. This fact is known as | cerebral localization. |
| The second largest part of the brain, located just below the posterior portion of the cerebrum, is the | cerebellum. |
| The most numerous cerebral tracts are the | association tracts. |
| The set of coordinated commands that control the programmed muscle activity mediated by extrapyramidal pathways is called the | motor program. |
| The cortex is capable of storing and retrieving information from both short-term and long-term | memory. |
| The reticular activating system maintains | consciousness. |
| If the ventral nerve root of a spinal nerve were destroyed, a person would lose _____ related to that pathway. | willed movement |
| Which of the following is not true of the knee jerk reflex? | It is a flexor reflex. |
| The parasympathetic and sympathetic divisions always act with a cooperative influence, and through summation of the impulses, the effect can be increased. | False |
| If the dorsal root ganglia of the spinal nerve were destroyed, a person would lose _____ related to that pathway. | sensory perception |
| Visit this link (Links to an external site.) to watch an animation of the events that occur when a hormone binds to a cell membrane receptor. A small molecule binds to a G protein, preventing its activation. What direct effect will this have on signaling | . Adenylyl cyclase will not be activated. |
| Visit this link (Links to an external site.) to watch an animation showing the role of the hypothalamus and the pituitary gland. Which hormone is released by the pituitary to stimulate the thyroid gland? | thyrotropin |
| Visit this link (Links to an external site.) to view an animation describing the location and function of the pancreas. What goes wrong in the function of insulin in type 2 diabetes? | the cells don't respond to insulin like they should |
| Watch this video (Links to an external site.) to learn more about how the structures of the ear convert sound waves into a neural signal by moving the “hairs,” or stereocilia, of the cochlear duct. Specific locations along the length of the duct encode s | The ossicles |
| Watch this animation (Links to an external site.) to learn more about the inner ear and to see the cochlea unroll, with the base at the back of the image and the apex at the front. Specific wavelengths of sound cause specific regions of the basilar membr | the apex of the cochlea, between the base and the apex of the cochlea |
| Watch this video (Links to an external site.) to learn more about a transverse section through the brain that depicts the visual pathway from the eye to the occipital cortex. The first half of the pathway is the projection from the RGCs through the optic | electrical signals |
| Please watch the follow animation and answer the question below. | The inpulse to the Perkinje Fiber |
| The process of red cells are production in the marrow of certain bones is referred to as | Erythropoiesis |
| Blood volume per kilogram of body weight varies inversely with: | body fat. |
| What is the functional significance of large areas of cardiac muscle being electrically coupled to form a single functional syncytium? | Because they form a syncytium, muscle cells can pass an action potential along a large area of the heart wall, stimulating contraction in each muscle fiber of the syncytium. |
| The vagus is said to act as a “brake” on the heart. This situation is called | vagal inhibition. |
| The ability of the lungs and thorax to stretch is referred to as | compliance. |
| Which of the following is not a means of transporting oxygen in the blood? | Combined with the bicarbonate ion (HCO3–) |
| Excessive fluid in the pleural cavity would be most likely to cause: | decreased vital capacity. |
| The symbol HbNCOOH– is used for: | carbaminohemoglobin. |
| Which of the following helps determine the amount of oxygen that diffuses into the blood each minute? | The total functional surface area of the respiratory membrane, Alveolar ventilation, The oxygen pressure gradient between alveolar air and incoming pulmonary blood |
| Stimulation of gastric juice secretion occurs in all of the following phases except the _____ phase. | digestive |
| During which stage of swallowing is there a risk of food entering respiratory pathways? | Oropharyngeal |
| What percentage of this blood flow comes from the hepatic portal system? | 80% |
| Glucose moves from the GI tract into the circulatory system by the process of | cotransport. |
