21. Describe a reflex arc, stating all the parts and the direction of flow of the action potential.
Dear Student,
Reflex arc diagram:
Reflex arc :
It is the nerve pathway involved in reflex action and it has a synapse between sensory and motor nerves .
Hope this helps you
21. Describe a reflex arc, stating all the parts and the direction of flow of the action potential.
What is pupillary reflex action? Describe how clinicians use pupillary reflex to determine if certain parts of the brain is damaged.
The most common form of reflex arc is the three-neuron arc, which consists of a sequence of neurons receiving sensory information, transmitting this information into the central nervous system for processing, and finally signalling muscles. What is the correct orderf neurons in such a reflex? unipolar- multipolar ntermeuron efferent- interneuron unipolar afferent+ interneuron bipolar efferent afferentinterneuron- Chemicals that cross over the synaptic cleft are called: electrical transmitters synaptic transmitters neurotransmitters chemotransmnitters D Bof 14 Critical thinking question 18.7 (p.407) ineffective...
Describe the reflex arc and its various structures. Explain exactly what happens there and how.
Describe the creation of the action potential from start to finish, discussing the flow of ions across the membrane. Make sure describe each step.
Describe the process of action potential
What is the difference between ion and flow and cellular response when an action potential is heading down an axon and when an action potential is about to reach synaptic potential?
please answer all parts of this question 2. Consider the junction potential a. Describe how and why a junction potential occurs. What is the error, in terms of concentration, if a junction potential changes the true b. cell voltage by 1.50 millivolts in a potentiometric determination of an analyte? Show the relevant calculations. c. Describe at least one way in which the error due to a junction potential can be eliminated or at least significantly reduced.
Describe the events of an action potential is conducted down the membrane of an axon and how it is transmitted to another cell across a synapse causing an IPSP or an EPSP.
All parts needed. will give thumbs up for ALL parts. short answers needed. 1. The action potential has just come down the T-tubule of a muscle cell a. Describe the molecular events that now take place to cause ultimately contraction and finally relaxation of the muscle cell. Name the molecular players involved including receptors, calcium-binding proteins, organelle involved and contractile proteins. Abbreviations are acceptable. b. Describe how ATP and conformation changes in myosin dictate myosin-actin cross-bridge cycle. C. Skeletal muscle...
An action potential occurs at the membrane of an axon because a) negatively charged Na+flow into the cell b) positively charged Na+flow out of the cell c) positively charged Na+flow into the cell d) negatively charged Na+flow out of the cell e) none of the above
