Brain and Cranial
for anatomy and physciology
| Question | Answer |
|---|---|
| What are the THREE major portions of the brain? | cerebrum, cerebellum, brainstem |
| What are the THREE general functions of the cerebrospinal fluid? | Buoyancy, protection, chemical stability |
| Why is it difficult or impossible to deliver medications such as antibiotics and cancer drugs to brain by intravenous injection? | Brain Barrier System |
| Medulla oblongata:Cardiac center? | Adjusts rate and force of heart |
| Medulla Oblongata:Reflex centers? | coughing, sneezing, gagging, swallowing, vomiting, salivation, sweating, movements of tongue and head |
| Medulla Oblongata:Respiratory Centers? | Control rate and depth of breathingFor |
| Medulla Oblongata:Vasomotor Center? | Adjusts blood vessel diameter |
| What is the cerebellum involved in? | muscle contractions and motor coordination - comparing textures without looking at them - keeping time (temporal judgment) - controlling emotional impulses |
| Which brain structure is called “gateway to the cerebral cortex”? | Thalamus |
| What is the GENERAL function of the hypothalamus? | Homeostatic regulation, control center of autonomic nervous system and endocrine system |
| Hypothalamus: Controls anterior pituitary | Regulates growth, metabolism, reproduction, and stress responses |
| Hypothalamus:Autonomic effects | Major integrating center for autonomic nervous system, influences heart rate, blood pressure,gastrointestinal secretions, motility |
| Hypothalamus:Thermoregulation | Hypothalamic thermostat monitors body temperature Activates heat-loss center when temp is too high Activates heat-promoting center when temp is too low |
| Hypothalamus: Water and Food intake | Hunger and satiety centers monitor blood glucose and amino acid levels Produce sensations of hunger and satiety Thirst center monitors osmolarity of the blood |
| Hypothalamus:Rythm of sleep and waking | Controls 24-hour (circadian)rythm of activity |
| Hypothalamus:Memory | Mamillary nuclei recieve signals from hippocampus |
| Hypothalamus:Emotional Behavior | Anger, aggression, fear, pleasure and contentment |
| Which part of the brain is the seat of sensory perception, memory, thought, judgment, and voluntary motor actions? | Cerebrum |
| Gray matter (i.e., somas of neurons) of the cerebrum constitutes what THREE structures? | Cerebral cortex, basal nuclei, limbic system |
| What is cerebral cortex? | cognition:sensory perceptions, thought, reasoning, judgement, memory, imagination, intuition |
| what is basal nuclei? | motor control |
| What is the limbic system? | emotion and learning |
| Centers for gratification and aversion are present in what system of cerebral structures? | Limbic System |
| Which TWO anatomical parts of the limbic system are responsible for memory and emotion? Which of these parts is responsible for memory and which for emotion? | Hippocampus-memory amygdala-emotion |
| Where are memories formed? | Hippocampus |
| Does hippocampus store memories? | no |
| Where are long-term memories stored? | cerebral cortex |
| Which structure of the limbic system (or cerebrum, or brain) does store emotional memory? | Amygdala-brain |
| Which structure of the brain does remember motor skills? | cerebellum |
| Which part of the cerebrum (or brain) is responsible for planning, moral judgment, and emotional control? | prefrontal cortex |
