Description:

The paper first discusses nerve conduction, action potentials and membrane potentials. The paper then looks at the hormones insulin and glucagon and their role in maintaining blood glucose levels. Finally, the paper defines Type I and Type II diabetes and explains the differences between them.

Outline:
Nerve Potentials and Impulse Propagation
Role of Insulin and Glucagon in Maintaining Blood Glucose Levels
Type I and Type II Diabetes

From the Paper:

"Neurons in the nervous system are linked together in circuits, the simplest of which consists of a sensory neuron receiving input from a sensory receptor cell such as a stretch receptor in a muscle, and a motor neuron which would cause the muscle to contract (Wilson, 2000, 232). This is a simple reflex circuit such as one which causes the knee-jerk reaction. The passage of an electrical impulse down a neuron is caused by a flow of ions through channels in the nerve cell membrane. Changes in the electrical currents cause changes in the membrane potential of the neuron.
"At rest, a neuron maintains a potential difference across its membrane known as the resting potential (232). The resting potential of a neuron is maintained by three factors: a large number of potassium channels in the membrane which allow potassium ions to flux easily across the membrane; a concentration gradient for potassium ions, with the greater concentration being inside the cell; and Na-K ATPase, which functions as a pump to maintain the concentration gradients of potassium and sodium across the neuron membrane."
