In other cells, such as gland cells and ciliated cells, it is believed that the membrane voltage is important to the execution of cell function. The origin of the membrane voltage is the same in nerve cells as in muscle cells. In both cell types, the membrane generates an impulse as a consequence of excitation.This impulse propagates in both cell types in the same manner. What follows is a short introduction to the anatomy and physiology of nerve cells.2) numerous short processes of the soma, called the dendrites; and, (3) the single long nerve fiber, the axon. These are described in Figure 2.1. The body of a nerve cell (see also (Schad and Ford, 1973)) is similar to that of all other cells.
The bruising that you sustain after eyelid surgery depends on the extent of the surgery. In general, the bruising resolves fairly quickly in 7 to 10 days. The purple discoloration will turn yellow and then slowly fade away with time. The swelling from eyelid surgery can take several months to completely resolve. The skin around the eyes is very fine.
Bruises develop when small blood vessels under the skin tear or rupture, most often from a bump or fall. Blood leaks into tissues under the skin and causes the black-and-blue color.As bruises (contusions) heal, usually within 2 to 4 weeks, they often turn colors, including purplish black, reddish blue, or yellowish green. Sometimes the area of the bruise spreads down the body in the direction of gravity.A bruise on a leg usually will take longer to heal than a bruise on the face or arms.Most bruises are not a cause for concern and will go away on their own. Home treatment may speed healing and relieve the swelling and soreness that often accompany bruises that are caused by injury.s bruises (contusions) heal, usually within 2 to 4 weeks, they often turn colors, including purplish black, reddish blue, or yellowish green.
