Synapse By: Thomas MartinsenObjectives: The students will learn about Summation and Neurotransmitters. Also theywill learn and understand how signals are transferred through neurons.Information:Electrical synapses – Occurs when two cells are joined end to end by gap junctions.Theses occur between cardiac muscle and some smooth muscle.Chemical synapses – They use a chemical transmitter called a neurotransmitter to senda signal from the presynaptic cell to the postsynaptic cell.Spatial summation – The sum of the local potentials reaches the threshold potentialthus produces an action potential.Temporal summation - When sympatric knobs stimulate a postsynaptic neuron in rapidsuccession their effects can add up and produce an action potential.Neurotransmitters- Are how the neurons talk to each otherAcetylcholine – It is in a class of its own because of its unique chemical structure. It ismade up of acetate with choline.
Amine – They are created from amino acid molecules, tyrosine, tryptophan, or histidine.They are found in regions of the brain and affect the learning, emotions, and motorcontrol.Amino acids- Are the most common neurotransmitters in the central nervous system.They are found in the cells of the body, and they are used to create structural andfunctional proteins.Neuropeptide– They are short amino acids also called polypeptides. They havefunctions to control the hormones and the regulate digestive function.Questions: To help make you understandWhat are the main functions of neuropeptides?Where are Amine’s mainly found in the body?Why is the Acetylcholine unique?The information above should have helped you understand what is in theneurotransmitters and how they work. Also help understand what different parts of thesummation do what within the cells.

In other words, they form the “wiring” of the nervous system’s information circuits. Glia or glial cells, on the other hand, do not usually conduct information but support the function of neurons in various ways. Some of the major types of Glia and neurons are described in the following sections.Verification Questions about Students must be Other lesson able to answer Resources(Steps to check for EX: How can you questions forstudent classify different types reassurance of Anatomy andunderstanding) of neurons? knowing the Physiology text information book

Strong permeability of potassium ions (K +). Weak permeability of sodium ions (Na+). Impermeability of large anions. Local Potential: Stimulation of neuron by chemical, light, heat, or mechanical distortion -Local potentials are graded; that is, they vary in magnitude. -Local potentials are decremental; that is they get weaker the farther they spread from the point of stimulation. -Local potentials are reversible. If the stimulation ceases, the membrane potential drifts back to resting membrane potential without affecting the cell. Action Potential: Change in membrane potential in an excitable tissue that acts as an electric signal and is propagated in an all-or- none fashion -It begins with a steady depolarization called the generator potential. If the generator potential reaches a critical voltage called the threshold, the membrane will continue to depolarize, followed by a period of repolarization and then a

Nerve impulses have been found to travel as fast as 100 m/s. What could account for the difference between your answer to Question 2 and this value obtained by researchers? Our value was 25.59 so it is significantly slower than the result the researchers obtained. the reasons probably was the area that was hit and maybe it wasn’t the exact spot it needed to hit.Assume the speed of a nerve impulse is 100 m/s. How does this compare to the speed of electricity in a copper wire (approx. 3.00 108 m/s)? It is a lot slower.Compare the data you obtained in this experiment with other members of your group/class. Can individual differences be attributed to any physical differences (body shape/s ize, muscle mass, physical fitness level)? Yes definitely the persons height and weight contributes to their reflexes and how fast or slow it may be. for example a person who works out regularly may be faster than a person who is out of shape.
