Chapter 9, Problem 33RQ
Summary Introduction
To explain: The reason behind disruption in normal brain functioning because of lowered osmolarity and Na+ concentration causing seizures.
Introduction: All the cells in the body have their own osmolarity and ionic concentrations in them according to their function and physiological condition of the body. These are maintained at steady state by different methods which are called as homeostatic processes. Maintenance of homeostasis is very important to enable the cell perform its function correctly.

Sodium is an incredibly important substance in our body. You may remember from module one that sodium ions play a crucial role in conducting nerve impulses during depolarization. You may also remember from biology 20 that sodium is involved in muscle contractions. Hyponatraemia has a condition where there is too little sodium in the body. This can result on difficulty processing thoughts nausea decreased ability to balance seizures in coma on the other hand an excessive amount of sodium or hyponatraemia in the body can also lead to many different neurological problems including seizures in coma.
Katrina has an excessive amount of sodium ions in her blood plasma. This is occurring despite the fact that she has been watching her salt intake and ensuring that she's drinking enough fluid throughout the day.
Katrina has an aldosterone imbalance.

After discussing his case with his physician, he learned that he had probably been the victim of pufferfish poisoning. The active toxin in the tissues of this fish is a chemical called tetrodotoxin (TTX). Tetrodotoxin is in a class of chemicals known as neurotoxins because it exerts its effects on neurons. The specific action of tetrodotoxin is that it blocks voltage-gated sodium ion channels.
Define the following phrases and terms associated with the signs and symptoms of Dr. Westwood’s TTX poisoning:
diaphoresis
motor dysfunction
paresthesias
cyanotic
hypoventilating
bradycardia
gastric lavage
oxygen saturation
As mentioned in the case description, tetrodotoxin is a molecule that blocks voltage-gated sodium ion channels. What is a voltage-gated sodium ion channel and what is its function?
When nerve cells are at rest, there is an unequal amount of positive and negative charges on either side of a nerve cell membrane. This charge difference creates an electrical potential.…

In low doses it can cause a slight numbness (people eat contaminated pufferfish sometimes!), in high doses it is lethal. Why is this the case? It prevents glutamate uptake and reuptake, causing seizures in the brain Ob. It causes excess neuronal activity, leading to excitotoxicity and cell death It destroys myelin around axons, slowing action potential propagation It prevents action potentials from being initiated, stopping all synaptic transmission O 0 o oarrow_forwardIn the introduction section the authors wrote “In general, the polarity-dependent mechanisms are recognized to cause membrane depolarization by anodal stimulation which increases cerebral excitability, or membrane hyperpolarization by cathodal stimulation leading to a decrease in neuronal excitability.” Based on this quote what affect, if any, does anodal stimulation have on ion channels?arrow_forward
- The normal concentrations for intracellular and extracellular potassium in a neuron are [K+]in = 150 mM and [K+]out = 5 mM, respectively. Due to an electrolyte imbalance, a patient has the following intracellular and extracellular concentrations of potassium: [K+]in = 140 mM and [K+]out =2 mM. Using the Nernst equation (Chapter 4), calculate the equilibrium potential for potassium in the cells with normal K+ distributions and of the diseased patient. Refer back to Question #1.
