Excitable cells, such as neurons and muscle cells, have the ability to generate electrical signals called action potentials in response to stimuli. These cells play a crucial role in transmitting signals within the nervous system and facilitating muscle contractions.
Nervous tissue, specifically neurons, carry electrical impulses from the brain to other parts of the body. These neurons transmit information in the form of electrical signals known as action potentials.
Factors that contribute to making a tissue excitable include the presence of ion channels, membrane potential changes, and the ability of the tissue to generate action potentials.
I think the answer you're looking for here is nervous tissue which carries action potentials, or nervous impulses, between the tissues and are central nervous system. However, from another point of view you could also consider the cardiovascular system as carrying hormonal messages throughout the body.
Yes, the intensity of the stimulus can be indicated by the frequency of action potentials generated by the neurons in response to that stimulus. A higher intensity stimulus typically leads to a higher frequency of action potentials being fired by the neurons.
Nervous tissue carries electrical impulses from the brain throughout the body. This tissue is composed of neurons, which transmit signals, and glial cells, which support and protect the neurons. The electrical impulses, or action potentials, allow for communication between the brain and various organs and muscles, facilitating coordination and response to stimuli.

nervous tissue
Neurons are considered excitable tissue because they can respond to stimuli and generate electrical impulses, known as action potentials. This excitability is due to the unique properties of their cell membranes, which contain ion channels that open and close in response to changes in voltage or neurotransmitter binding. When a neuron is sufficiently stimulated, it undergoes depolarization, allowing sodium ions to enter, which propagates the electrical signal along the axon. This ability to transmit signals is essential for communication within the nervous system and between neurons.
Nervous (nerve) tissue.
The pacemaker is known as the SA node (sinotrial) and it generates action potentials to the AV node and then to the bundle of his down to the purkinje fibers. The branching of cardiac muscle tissue and the intercalated discs allow action potentials to propagate to other cardiac mt cells. The autorhythmicity of the heart is attributed to the fact that it creates its own action potentials from the SA node and can be generated independently from the rest of the body. The heart's autorhythmicity also prevents it from reaching tetanus (like a skeletal muscle does), because myocardial tissue only allows a certain amount of action potentials through before it reaches its absolute refractory period when it comes to a plateau and after the wave drops again and gets hit with another action potential it has already rested.
