Various sensors are embedded in the
membrane of a neurone. If a sensor is open,
ions flow through. Many sensors only open
to specific input.
M
opens to
mechanical
forces,
A
opens to
acidic
or chemical
forces, and
T
opens to
temperature
changes. If there are enough sensors open,
positive ions flow into the neurone and
send a dangermessage to the spinal cord.
