  2. Effects of high altitude on humans - Wikipedia

    en.wikipedia.org/wiki/Effects_of_high_altitude...

    The effects of high altitude on humans are mostly the consequences of reduced partial pressure of oxygen in the atmosphere. The medical problems that are direct consequence of high altitude are caused by the low inspired partial pressure of oxygen, which is caused by the reduced atmospheric pressure, and the constant gas fraction of oxygen in ...

  3. High-altitude adaptation in humans - Wikipedia

    en.wikipedia.org/wiki/High-altitude_adaptation...

    Hypoxia is a primary contributor to fatalities within mountaineering groups, making it a significant risk factor within high-altitude related challenges. [ 19 ] [ 20 ] In women, pregnancy can be severely affected, such as development of preeclampsia , which causes premature labor , low birth weight of babies, and often complicates with profuse ...

  4. Altitude sickness - Wikipedia

    en.wikipedia.org/wiki/Altitude_sickness

    Altitude sickness, the mildest form being acute mountain sickness (AMS), is a harmful effect of high altitude, caused by rapid exposure to low amounts of oxygen at high elevation. [ 1 ] [ 2 ] [ 3 ] People's bodies can respond to high altitude in different ways.

  5. High-altitude cerebral edema - Wikipedia

    en.wikipedia.org/wiki/High-altitude_cerebral_edema

    High-altitude cerebral edema (HACE) is a medical condition in which the brain swells with fluid because of the physiological effects of traveling to a high altitude. It generally appears in patients who have acute mountain sickness and involves disorientation, lethargy, and nausea among other symptoms.

  6. Hippocampus - Wikipedia

    en.wikipedia.org/wiki/Hippocampus

    Humans have two hippocampi, one in each hemisphere of the brain.They are located in the medial temporal lobe of the brain. In this lateral view of the human brain, the frontal lobe is at the left, the occipital lobe at the right, and the temporal and parietal lobes have largely been removed to reveal one of the hippocampi underneath.

  7. Death zone - Wikipedia

    en.wikipedia.org/wiki/Death_zone

    Many deaths in high-altitude mountaineering have been caused by the effects of the death zone, either directly by the loss of vital functions or indirectly by poor decisions made under stress (e.g., not turning back in deteriorating conditions, or misreading the climbing route), or physical weakening leading to accidents (e.g., falls).

  8. Limbic system - Wikipedia

    en.wikipedia.org/wiki/Limbic_system

    The limbic system, also known as the paleomammalian cortex, is a set of brain structures located on both sides of the thalamus, immediately beneath the medial temporal lobe of the cerebrum primarily in the forebrain. [1] Its various components support a variety of functions including emotion, behavior, long-term memory, and olfaction. [2]

  9. Human brain - Wikipedia

    en.wikipedia.org/wiki/Human_brain

    Information about the structure and function of the human brain comes from a variety of experimental methods, including animals and humans. Information about brain trauma and stroke has provided information about the function of parts of the brain and the effects of brain damage. Neuroimaging is used to visualise the brain and record brain ...
