Bad Fish: Human Anatomy and Physiology Edition 1. Present the “Doctor’s Notes” portion of the case with a description of the following terms or concepts: Diaphoresis: Technical name for sweating. Motor dysfunction: A defect within the motor system causing an inability to produce or control motion. Paresthesias
: An abnormal sensation of the skin such as tingling, pricking or numbness Cyanotic
: Discoloration of the skin and mucous membrane, indication that oxygen in the blood is diminishing Hypoventilating
: Respiratory depression, occurring when ventilation is inadequate to perform necessary gas exchange Bradycardia
: Abnormally slow heart rate Gastric lavage
: Act of washing out the stomach with sterile water or a saltwater…show more content…
4. As mentioned in the case description, tetrodotoxin is a molecule that blocks voltage-gated sodium ion channels. Describe the structure of a sodium ion. The sodium ion has eleven protons and ten electrons, indicating that the first orbital shell has two electrons and the second shell has eight electrons (1s2 2s2 2p6) 5. What is a voltage-gated sodium ion channel? What is it made of? What is its function? A voltage-gated sodium ion channel allows for sodium ions to travel across the cell membrane. Voltage-gated sodium ion channels are made of amino acids and are necessary for the initiation and propagation of action potentials. 6. Why do sodium ions need channels in order to move into and out of cells? Sodium ions need channels in order to move in and out of the cell because to move in and out on the cell the ion has to pass through the plasma membrane. However the plasma membrane works as a barrier separation the cell from the extracellular fluid, and the interior of the plasma membrane contain hydrophobic tails, which blocks the movement of charged ions to move in and out. The only way a sodium ion can move through the plasma membrane is through the use of sodium ion…show more content…
15. Briefly describe the role of the autonomic nervous system in human physiology. What are the two divisions of this system? The autonomic nervous system regulates the function of organs that have involuntary responses. The two divisions of the autonomic nervous system are the parasympathetic (rest and digest) and the sympathetic (fight or flight) nervous system. 16. Atropine was administered in the ED as part of Dr. Westwood’s care. What effect did it have on his vitals after it was administered? Atropine acts as an antagonist within the central nervous system, which means it acts as
a blocker of specific cellular functions. What part of the autonomic nervous system does atropine block to produce its effect on Dr. Westwood? Atropine was administered in response to the bradycardia; after it was administered it brought up his blood pressure as well has his heart rate. Within the parasympathetic nervous system, Atropine blocks the muscarinic receptor which then blocks acetylcholine (Ach). Because of the blockage of Ach the muscarinic receptor antagonist can block the vagal nerve from affecting the heart, and can then increase the heart
