While their size and shape vary with location in the nervous system, most neurones contain the same parts: a cell body; a number of highly-branched outgrowths of the cell body called dendrites; a single, long nerve fibre (or axon) extending from the cell body; and branches at the end of the nerve fibre (axon terminals).
My doctor said that usually happens when blood pressure is high and you get that strange head sensation.

Some potential causes of a heavy feeling in the head include: 1. Head and Neck Injuries. As mentioned before, head and neck injuries can both cause a heavy head feeling, due to damage to your brain or muscles. Sometimes your head feels heavy and numb as a result of the muscle strain as well. 2. Fatigue. If youâre out of shape or donât get enough exercise, then itâs possible that your heavy head feeling is due to fatigue and poor health.
