Use the word bank below to answer the following series of questions. Each sequence of questions will spell out a word when answered correctly. Two more words related to the correct word will be provided, from which you can practice writing the relationship problems. Try not to cheat by checking your answers after you complete the sequence. RELATIONSHIP PROBLEM #1 - ? / Second Messenger / cAMP
The receptor you would find on the effector cell recieving a stimulus from a parasympathetic postganglionic neuron. The lysing of PIP2 by phospholipase C ultimately results in the releasion of what ion from the endoplasmic reticulum? This occurs when the cell becomes more negative. The receptor located on all postganglionic neurons is of this functional classification. M Ach R are of this functional receptor classification. Name an inhibitory neuron. If K+ gates were opened on a resting cell's membrane, this would happen to the cell. If Ca++ is present, this molecule will reveal Actin's active site, allowing sarcomere shortening. If this neurotransmitter is bound to a receptor on another neuron, the neuron will be less likely to have an action potential. Albuterol stimulates these receptors. Increased heart rate is a characteristic result of stimulation by which division of the ANS? This is the primary protein effector in the IP3/DAG second messenger system. RELATIONSHIP PROBLEM #2 - ? / Action Potential / Ions
This neurotransmitter is secreted by all sympathetic postganglionic neurons. Increased glandular secretions are characteristic of this division of the ANS. If K+ channels were closed in a cardiocyte, the heart rate would... If Cl- channels were opened in a cardiocyte, the heart rate would... Upon eating some bad Fugu, what would happen to the rate of action potentials? What is the protein effector for the cAMP second messenger? What structure is responsible for delivering an action potential throughout a muscle fiber, ensuring uniform contraction? The sympathetic receptors you would find on the heart. RELATIONSHIP PROBLEM #3 - ? / ANS / Receptors
A drug used to treat Myasthenia Gravis patients. It blocks Ach-esterase to keep more Ach available in synapse. An inhibitory neurotransmitter. A drug that results in increased heart rate and dilated bronchi. A condition that stems from demyelination of axons and axonal scarring. The point on a neuron where threshold is reached and channels transition from mostly ligand operated to mostly voltage operated. The location of the preganglionic cell bodies of the sympathetic nervous system. Valium, Xanax, and Alcohol all stimulate secretion of this neurotransmitter. A drug that is antagonistic to bad mushrooms and pilocarpine. If overdose = flaccid paralysis. The term used to describe the occurence of action potentials only at gaps between myelination, called the nodes of ranvier. This term really describes the interomediolateral collumn, made up of the lateral gray horns. This substance is required for the myosin head to detach from the actin binding site and recock. What is the location of the parasympathetic preganglionic cell bodies? This drug is antagonistic to propanolol. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
