A nerve impulse is an electrical signal in which the nerve cells communicate with each other while transmitting a message from one part of the body to the other. The nerve impulse takes place in the nerve cell called a neuron. Neurons are the structural and functional units of the...
Sensory neurons are nerve cells that pick-up signals from the external environment to internal electrical impulses. A stimulus triggers this signal and activates the signal to be sent from the external environment to your spinal cord, to then your brain. For example, ...

A synapse is a site where nerve cells (neurons) are in contact, and electric signals or nerve impulses are transmitted. Synapses convert these electrical signals into chemical information that is communicated between neurons.Answer and Explanation: ...
Explain the process of transmission of nerve impulses. Describe the stimulation and conduction of an action potential. Briefly describe how the sympathetic and parasympathetic nervous system alter the rate of the sinoatrial (SA) node depolarization. Describe the resting potential for neurons. How is th...
Neurons are the building blocks of the nervous system. They are specialized cells in the nervous system that receive and send messages within that system.Answer and Explanation: The basic structure of a neuron includes the following: dendrites, soma, axon, myelin sheath, and terminal buttons. ...
(b) Describe how a nerve impulse crosses a synapse. Neuron: The excitable cells that propagate electrical impulses from one end of the cell to the other end are known as neurons. These cells form networks that process inform...
Learn more about this topic: Neuron Definition, Parts & Function from Chapter 2 / Lesson 2 166K Learn about neurons and their parts. Explore the structure, function, and types of neurons, and discover how neurons transmit and receive information. ...
Describe how nerve signals are propagated along axons and between different neurons. Explain how the Nervous system and Endocrine system "respond" to our sleep cycle. Describe the term: depolarization Explain how the nervous system and endocrine system ar...
