hi
human physiology:
what is a cerebral lobe not visible in an ordinary external inspection
what is a vein in the dura mater roughly parallel to the longitudinal fissure
what is the portion of the thalamus that passes through the third ventricle. I think is is the hypothalamus, but i'm not sure
what is the white matter tracts in the ventral portion of the midbrain.
Is is the spinothalamic tract?
can you please help me with these questions. I spent an hour looking it up in the internet, but i can't find the answer. please, These questions are about the brain.
I'm not sure what you mean by "external inspection." If this is from outside the head, none of the lobes are visible. In viewing the brain itself, all lobes of the cerebrum are visible, but only the occipital lobe is not clearly designated by sulci.
For your second question, since this is not my main area of expertise, I searched Google under the key words "brain longitudinal fissure vein" to get these possible sources:

For the third question, I used key words "thalamus third ventricle":

I searched for the "spinothalamic tract" to get these sources:

I hope this helps. Thanks for asking.
long term effect of a permanent move from sea level to a high altitude area ?
THERE ARE FOUR LOBES VISIBLE: FRONTAL, PARIETAL, OCCIPITAL AND TEMPORAL. Insula is grouped with the lobes but is burried within a fissure between the temporal and parietal lobes. Your answer is Insula.
The vein in the dura mater is called the 'dural venous sinus'.
All the answers are in the book, I am actually doing
I am actually workiung on the exact same questions right now.I thought the answer was "vein of Galen" for the Vein in the dura mater roughly parallel to the longitudal fissure. I'm still looking.p.s. read the chapter.

The long-term effects of a permanent move from sea level to a high altitude area can vary depending on the individual and how well they acclimate to the change in oxygen levels. Here are some potential physiological effects:
1. Increased Red Blood Cell Production: Moving to high altitudes with lower oxygen levels stimulates the body to produce more red blood cells to carry oxygen to tissues. This adaptation helps increase oxygen-carrying capacity, improving overall oxygen delivery to the body.
2. Increased Respiratory Rate: Breathing becomes more rapid and deeper to compensate for the lower oxygen levels. This can lead to an increase in respiratory rate, which helps facilitate gas exchange and ensures an adequate oxygen supply.
3. Vasodilation: Blood vessels in the body dilate in order to increase blood flow and oxygen delivery to various organs and tissues. This can help maintain oxygen saturation levels and prevent tissue damage.
4. Increased Lung Capacity: Over time, individuals may experience an increase in lung capacity to improve oxygen uptake. The lungs adapt by increasing the number and size of the alveoli, the tiny air sacs where gas exchange takes place.
5. Increased Nitric Oxide Production: High altitude exposure stimulates the production of nitric oxide in the blood vessels, which helps to improve blood flow and oxygen delivery to organs and tissues.
It is important to note that some individuals may experience altitude-related health issues, such as altitude sickness, which can include symptoms like headache, nausea, dizziness, and shortness of breath. Gradual acclimatization, staying hydrated, and proper rest can help minimize these effects.
It is recommended to consult with a healthcare professional before permanently moving to a high altitude area, as they can provide specific advice based on your individual health and medical history.
