Telencephalon and Diencephalon. |
|
|
Midbrain structures. (1) |
Mesencephalon. |
|
|
Hindbrain structures (2) |
Metencephalon, myelencephalon |
|
|
Brain areas of Telencephalon. |
Cerebral cortex, hippocampus, basal ganglia, limbic system. |
|
|
Brain areas of Diencephalon. |
Thalamus, hypothalamus. |
|
|
Brain areas of Mesencephalon. |
Superior coliculus, inferior coliculus. |
|
|
Brain areas of Metencephalon. |
Cerebellum, pontine motor nuclei. |
|
|
Brain areas of Myelencephalon. |
Medulla oblongota |
|
|
Function of thalamus. |
Relays sensory information. Think of a railway system. |
|
|
Hypothalamus function |
Regulates homeostasis |
|
|
Function of midbrain |
Part of visual and auditory pathways. Reflexive response to unfamiliar events. |
|
|
Function of cerebellum |
Coordination of movement |
|
|
Pons and medulla function |
Autonomic nervous system. (Respiration, heart rate, etc.) |
|
|
Function of hippocampus |
Coordinates storage and retrieval of long term memory |
|
|
Basal ganglia |
Forms habitual behaviors by dopamine release in receptors |
|
|
Which of these brain structures are involved with motor control? Cerebellum. Motor cortex. Somatosensory cortex. Hypothalamus. |
Cerebellum and motor cortex. |
|
|
Compared to baseline neural activity, what would be the level of response of basal ganglia dopamine receptors after an expected reward is obtained? |
No change compared to baseline. |
|
|
What type of hormone receptors exist in the surface of a cell membrane? |
Amino-acid based hormone receptors. |
|
|
Where are the receptors responsible for lipid-based hormones located in the cell? |
Cytoplasm |
|
|
How do cytokines affect glucocorticoid production? |
They increase glucocorticoids by stimulating the hypothalamus. |
|
|
When is myosin loosely attached to actin? |
When a muscle is at rest. |
|
|
What is the PROXIMATE mechanism that causes sarcoplasmic reticulum to release calcium? |
Action potential in the muscle fiber. |
|
|
What type of control is exhibited in the HPA axis? |
Negative feedback loop. HPA: Hypothalamus>Pituitary>Adrenal cortex |
|
|
T/F. Cortisol can inhibit the immune response. |
True. (Lecture 8) |
|
|
What two structures can the immune response trigger to release cortisol. |
Adrenal Cortex (directly) or the Hypothalamus (indirectly). |
|
|
How does insulin impact blood glucose levels? |
Decrease blood glucose levels through storage. |
|
|
How does glucagon impact blood glucose levels? |
Increases blood glucose by release. |
|
|
What is the purpose of "carbo-loading"? |
Storage of glycogen in excess for endurance fuel source. |
|
|
Must be able to diagram slides 20 and 21 from lecture 8! |
If you want that A, of course. |
|
|
Diabetes where body is unable to produce insulin. |
Type 1, genetic causes |
|
|
Type 2 diabetes. |
Constant hyperglycemic environment. Insulin receptors down-regulated and damaged. Glucose can't enter cells and causes nutrition defeciency. |
