2. Most tumors that originate in the brain are not cancer, but growth of any tumor within the confined space of the skull can put pressure on surrounding nervous tis- sue and thus harm neurons. Treating brain tumors with drugs is difficult because of the blood-brain barrier. Lipid-soluble drugs can penetrate this barrier, but they get into and affect all other cells too. Explain why.

could you also help with that "part a" right underneath? I'm not too sure how to answer that, thanks so much! "a. Based on this answer, what then do you think will happen if you suddenty break your diet and eat fried cheese and ice cream at a Christmas party? Any effect?? What might be some signs and symptoms one would expect?"

Endocrine glands ________. secrete hormones that travel through a duct to the target organs release neurotransmitters into the synaptic cleft secrete chemical messengers that travel in the bloodstream include sebaceous glands and sweat glands

Visit this site (http://openstaxcollege.org/l/neurolab) to see a virtual neurophysiology lab, and to observe electrophysiological processes in the nervous system, where scientists directly measure the electrical signals produced by neurons. Often, the action potentials occur so rapidly that watching a screen to see them occur is not helpful. A speaker is powered by the signals recorded from a neuron and it pops each time the neuron fires an action potential. These action potentials are firing so fast that it sounds like static on the radio. Electrophysiologists can recognize the patterns within that static to understand what is happening. Why is the leech model used for measuring the electrical activity of neurons instead of using humans?
The ________ exocrine gland stores its secretion until the glandular cell ruptures, whereas the ________ gland releases its apical region and reforms. holocrine; apocrine eccrine; endocrine apocrine; holocrine eccrine; apocrine
In 2003, the Nobel Prize in Physiology or Medicine was awarded to Paul C. Lauterbur and Sir Peter Mansfield for discoveries related to magnetic resonance imaging (MRI). This is a tool to see the structures of the body (not just the nervous system) that depends on magnetic fields associated with certain atomic nuclei. The utility of this technique in the nervous system is that fat tissue and water appear as different shades between black and white. Because white matter is fatty (from myelin) and gray matter is not, they can be easily distinguished in MRI images. Visit the Nobel Prize website (http://openstaxcollege.org/l/nobel_2) to play an interactive game that demonstrates the use of this technology and compares it with other types of imaging technologies. Also, the results from an MRI session are compared with images obtained from x-ray or computed tomography. How do the imaging techniques shown in this game indicate the separation of white and gray matter compared with the freshly dissected tissue shown earlier?
Pls help for each one
The colon contains a specialized cell. There is a big quantity of this type of cell. Name this specialized cell and give its function. ( i think it's goblet cells but not sure on the function)
please just true or false 1-Simple columnar absorption, secretion and move mucus by cilia. 2-Bacterium is cell. 3-All hormones are secreted inside the body, therefor its do not like the saliva. 4-Organisms differ from one to another but all are made up of one cell. 5-Action potentials normally travel from the axon terminal toward the cell body
molecular components not cellular.Answer carefully. Question: In terms of nerve action, describe 4 different molecular components involved. And for each, give a defect that would block nerve function.
Visit this site (http://openstaxcollege.org/l/NYTmotor) to read about an elderly woman who starts to lose the ability to control fine movements, such as speech and the movement of limbs. Many of the usual causes were ruled out. It was not a stroke, Parkinsons disease, diabetes, or thyroid dysfunction. The next most obvious cause was medication, so her pharmacist had to be consulted. The side effect of a drug meant to help her sleep had resulted in changes in motor control. What regions of the nervous system are likely to be the focus of haloperidol side effects?
