Neuron-a cell of the nervous system designed to conduct nerve impulses axon- the usually long process of a nerve fiber that generally conducts impulses away from the body of the nerve cell dendrite - a branched protoplasmic extension of a nerve cell that conducts impulses from adjacent cells inward toward the cell body. An axon (from greek, axis) also known as a nerve fibre is a long, slender projection of a nerve cell, or neuron, that typically conducts electrical impulses away lab exercise 4: the frog sciatic nerve . 3a nerve is a bundle of axons, and some nerves are less sensitive to lidocaine if a nerve, rather than an axon, had been used in the lidocaine experiment, the responses recorded at r1 and r2 would be the sum of all the action potentials (called a compound action potential.

Nervous system is composed of excitable nerve cells (neurons) and cells can vary in size and location, their communication with one another determines their function these nerves conduct impulses from sensory receptors to the brain and spinal cord human physiology/the nervous system 2 general functions of the cns brain, brain stem.

Neurophysiology lab report essay sample activity 1: effect of curare on the organism the overrall effect of the curare on the organism is that it prevents the flow neuron impulses from neuron to neuron activity 7: the rat nerve 2 had the fastest conduction velocity.
Membrane irritability is the ability to respond to a stimuli and convert it in to nerve impulses membrane conductivity is the ability to transmit that impulse that is created by membrane irritability. Transmission of nerve impulses the transmission of a nerve impulse along a neuron from one end to the other occurs as a result of electrical changes across the membrane of the neuron the membrane of an unstimulated neuron is polarized—that is, there is a difference in electrical charge between the outside and inside of the membrane. Exercise 3 neurophysiology of nerve impulses activity 1: the resting membrane potential 1 explain why increasing extracellular k+ reduces the net diffusion of. Exercise 3: neurophysiology of nerve impulses: activity 8: chemical synaptic transmission and neurotransmitter release lab report pre-lab quiz results you scored 100% by answering 5 out of 5 questions correctly. Nerve impulses have a domino effect each neuron receives an impulse and must pass it on to the next neuron and make sure the correct impulse continues on its path through a chain of chemical events, the dendrites (part of a neuron) pick up an impulse that’s shuttled through the axon and.
The neurons are highly irritable, or the ability to react to stimuli and convert them into nerve impulses, and conductivity, the ability to transmit an impulse along the cell membrane impulse transmission initiated by a chemical, electrical, mechanical and thermal stimulus. Lab report- neurophysiology of nerve impulses essay introduction neurons (also known as neurons, nerve cells and nerve fibers) are electrically excitable and the most important cells in the nervous system that functions to process and transmit information. Abstract 1 the responses of single afferent fibres of carotid body chemoreceptors to independent changes in arterial o 2 and co 2 tensions and ph were studied in the cat in vivo 2 the response curve obtained relating chemoreceptor activity to changes in arterial p o 2 was similar to an hyperbola the frequency of nerve impulses at first decreased rapidly as the p a,o 2 was raised and then.

The basic structure of a nerve is that of a cell body (soma), which has a single long nerve fibre (axon), attached at one end to the cell body and at the other end to another nerve cell body or to a structure requiring nerve impulses such as skeletal muscle.
