Defining a trigger range for ADC analogRead values

ok I started doing the IF statements for triggering the pins on the multiplexers, and theres got to be an easier way.

anyone care to condense??

byte count;

void setup()
{
pinMode (52, INPUT);         //external debounced switch pins 52 is temp up
pinMode (50, INPUT);        // 50 is temp down
pinMode (37, OUTPUT);       //pinS ODD 37-53 are outputs for multiplexers
pinMode (39, OUTPUT);
pinMode (41, OUTPUT);
pinMode (43, OUTPUT);
pinMode (45, OUTPUT);
pinMode (47, OUTPUT);
pinMode (49, OUTPUT);
pinMode (51, OUTPUT);
pinMode (53, OUTPUT);
Serial.begin (9600);

}

void loop()
{
if (digitalRead(52) == HIGH && count < 18) {
  count++;
  delay (200);
} else if (digitalRead(50) == HIGH && count > 0) {
  count--;
  delay (200);
}
