This can then lead to exocrine pancreatic insufficiency. Lupus. The autoimmune disease lupus can cause a rare condition called autoimmune pancreatitis, where the bodyâs T-cells (blood cells that fight infection) attack the pancreas. Autoimmune pancreatitis can lead to chronic pancreatitis and, in some cases, to exocrine pancreatic insufficiency,â Gress says.
Quick Answer. When a neuron is stimulated by another neuron, an ionic gradient is created across the neuron's plasma membrane, which creates an electric current flow in the neuron. The current flow travels down the axon and causes neurotransmitters to be released at the terminals to stimulate downstream neurons. Continue Reading
Typically, a stimulus causes ionic changes in the receptor neuron's dendrites, which lead to the formation of action potentials in the receptor neurons. These action potentials travel the sensory neuron, which connects to a motor neuron (and possibly an ascending neuron) in the spinal cord.The action potential causes neurotransmitter release within the presynaptic cell. The neurotransmitter binds to the postsynaptic cell and elicits an action potential there.he nervous system has many types of sensory neurons. Nerve endings on one end of each neuron are encased in a special structure to sense a specific stimulus. 1  Chemoreceptors sense chemicals. 2  The olfactory bulb that monitors your sense of smell has chemoreceptors that sense odors (chemicals in the air).
