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.

What muscle contains self excitable cells?
The heart muscle contains self-excitable cells known as pacemaker cells. These cells generate electrical signals that control the heart's rhythm by initiating the contraction of the heart muscle.
What are the only two types of cells that have excitable membranes?
The only two types of cells that have excitable membranes are neurons and muscle cells. Neurons transmit electrical signals in the nervous system, while muscle cells generate electrical signals that lead to muscle contraction.
Neurons as with other excitable cells of the body have two major physiological properties and?
The two major physiological properties of neurons, like other excitable cells, are excitability (ability to generate electrical impulses) and conductivity (ability to transmit these impulses along the length of the cell). These properties allow neurons to communicate within the nervous system and regulate various bodily functions.
What are the electro physiological methods for studying excitable tissues?
Electrophysiological methods for studying excitable tissues include patch-clamp recording to measure single-channel currents, voltage-clamp techniques to control and measure membrane potential changes, and extracellular field potential recording to study overall activity of a population of cells. These methods provide valuable insights into the electrical properties of excitable tissues at cellular and network levels.
What kind of cells do dermis make?
The dermis is made up of connective tissue cells called fibroblasts, as well as immune cells like mast cells and macrophages. These cells work together to provide structural support, elasticity, and protection to the skin.
What muscle contains self excitable cells?
The heart muscle contains self-excitable cells known as pacemaker cells. These cells generate electrical signals that control the heart's rhythm by initiating the contraction of the heart muscle.
Is red blood cell membrane an excitable tissue?
No, the red blood cell membrane is not an excitable tissue. Excitable tissues are able to generate and conduct electrical impulses, which is not a function of red blood cells. Red blood cells are primarily involved in transporting oxygen and carbon dioxide in the bloodstream.
What are the only two types of cells that have excitable membranes?
The only two types of cells that have excitable membranes are neurons and muscle cells. Neurons transmit electrical signals in the nervous system, while muscle cells generate electrical signals that lead to muscle contraction.
What has the author D J Aidley written?
D. J. Aidley has written: 'The physiology of excitable cells'
Action potentials can be generated by virtually all cells of the body because all cells possess cell membranes?
While all cells have cell membranes, action potentials are mainly generated by excitable cells like neurons and muscle cells due to the presence of voltage-gated ion channels. These channels allow for rapid changes in membrane potential, leading to the generation of action potentials. Non-excitable cells do not typically generate action potentials.
What has the author Edward Joseph Vigmond written?
Edward Joseph Vigmond has written: 'Electrical coupling mechanisms of excitable cells'
How would you use the word excitable in a sentence?
He's just an excitable boy. She is too excitable to make a good soldier.
What is the adverb for excitable?
The word excitable is an adjective. The adverb form is excitedly.
What is the root word of excitable?
The root word of "excitable" is "excite."
When was Excitable Boy created?
Excitable Boy was created on 1978-01-18.
What has the author F A Miles written?
F. A. Miles has written: 'Excitable cells' -- subject(s): Nervous system, Neurology, Popular works
How are local and action potentials similar?
Local and action potentials both involve changes in membrane potential due to the movement of ions across the cell membrane. They both follow the same basic principles of depolarization and repolarization. However, action potentials occur in excitable cells like neurons and muscle cells, while local potentials are smaller, graded changes in membrane potential that occur in non-excitable cells.
