2023年11月21日 · A neural impulse is an electrochemical signal that is sent from neurons to other neurons, or to effectors, like muscles and glands that are controlled by neurons.Neural impulses are important ...

The likely effect on a neuron of two excitatory signals and twenty inhibitory signals is: a) transmission of a nerve impulse. b) transmission of a nerve impulse releasing excitatory neurotransmitters at the next synapse. c) transmission of a nerve impulse; Explain the role of ion channels, threshold, and synapse.

Describe the events that occur at a chemical synapse when a single nerve impulse arrives at a synaptic end bulb. Describe how this may lead to the initiation of a nerve impulse in the neighboring neuron. Describe the axon variables that can influence the speed at which an action potential is conducted in a mammalian neuron.

Explain how a nerve impulse propagates along the axon of a neuron and how the electrical impulse can be transmitted across the synaptic gap. Describe how a nerve impulse crosses a chemical synapse, including why it can only travel in one direction. Explain the process of excitatory synaptic transmission versus inhibitory synaptic transmission.

Explain nerve conduction in details . Describe how action potentials are propagated along axons. Explain how a nerve cell communicates a message to another nerve or muscle or gland. Describe how the nervous system responds to stimuli. Explain briefly the innervation of sympathetic and parasympathetic nerve fibers. Define a nerve tract.

Explain how a nerve impulse propagates along the axon of a neuron and how the electrical impulse can be transmitted across the synaptic gap. Describe how neurons communicate. To do so, you must address: * resting membrane potential, graded potential, IPSPS, EPSS, the role of sodium, potassium and calcium generation of an action potential ...

(a) Describe an electrical nerve impulse in terms of charges on either side of the neuron membrane. (b) Describe how a nerve impulse crosses a synapse. How does TTX act on the neuron? Why is it that the electrical impulse cannot pass from neuron to muscle cell? How is an interneuron different from a motor neuron or a sensory neuron?

Nerve impulse: A nerve impulse is an electrical signal that can communicate with one another. It can travel from dendrites of one neuron to the axon of another neuron. It can travel in the form of an action potential. Answer and Explanation: 1

To pass a nerve impulse onto another nerve cell. Nicotinic receptors in the muscle fibers bind the neurotransmitter ___________________. Paired-pulse facilitation is a form of short-term homosynaptic plasticity that results in an increase in the amplitude of the post-synaptic potential to successive action potentials because of an accumulation ...

A nerve impulse is a signal that travels along a neuron or nerve fiber. The speed at which a nerve impulse travels depends on various factors, such as the diameter of the axon, the presence of myelin sheath, and its thickness.
