A principal/essential node is one where three or more circuit elements join.
A reference node is a chosen principal node from which you measure the voltage or current to other principal nodes.

This will vary depending upon what the lymph node biopsy is for. Sometimes all or part of just one node is collected; other times several nodes may be sampled.

Given a list and a node to delete, use the following algorithm:

// Are we deleting the head node?

if (node == list.head)

{

// Yes -- assign its next node as the new head

list.head = node.next

}

else // The node is not the head node

{

// Point to the head node

prev = list.head

// Traverse the list to locate the node that comes immediately before the one we want to delete

while (prev.next != node)

{

prev = prev.next;

}

end while

// Assign the node's next node to the previous node's next node

prev.next = node.next;

}

end if

// Before deleting the node, reset its next node

node.next = null;

// Now delete the node.

delete node;
