What cells transmit and receive impulses?

nervous tissue.


The ability of the myocardial cells to respond to an electrical stimulus is known as what?

The ability of myocardial cells to respond to an electrical stimulus is known as excitability. This property allows the cardiac muscle cells to generate action potentials in response to electrical impulses, facilitating coordinated heart contractions and maintaining effective blood circulation. Excitability is a crucial aspect of the heart's electrical conduction system.


What type of muscle would be considered autorhythmic?

Cardiac muscle is considered autorhythmic, meaning it has the ability to generate its own electrical impulses without the need for external stimulation. This property allows the heart to beat independently of nerve input.


What biological tissues carry current?

Biological tissues that can carry current include muscle tissues, particularly cardiac and skeletal muscles, due to their ability to generate action potentials for contraction. Nerve tissues also conduct electrical signals through the transmission of impulses along neurons. Additionally, certain types of connective tissues, like those found in the heart, can facilitate electrical conduction. These tissues utilize ions such as sodium, potassium, and calcium to create electrical gradients essential for their functions.


What carries cardiac impulses to the myocardium?

Cardiac impulses are carried to the myocardium via specialized muscle cells called Purkinje fibers. These fibers are part of the cardiac conduction system and help to transmit electrical signals rapidly and efficiently throughout the heart muscle.

Muscle tissue has four characteristics what are they?

Contractility - the ability of a muscle to shorten. Extensibility - the ability to lengthen. Elasticity - the ability to return to their original shape. And, Excitability - can be triggered by electrical stimulation.


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.

How do T-tubules contribute to the contraction of muscle fibers?

T-tubules are structures in muscle cells that help transmit electrical signals for muscle contraction. They allow for the rapid spread of these signals throughout the cell, ensuring coordinated muscle fiber contraction.


What property of potassium ions allows them to transmit?

Potassium ions have the ability to pass through ion channels in cell membranes, allowing them to transmit electrical signals. This movement of potassium ions is crucial for nerve cell communication and muscle contractions.


How might you Draw an analogy between the nerves in the human body and electrical wires?

Nerves in the human body can be likened to electrical wires in how they transmit signals. Just as electrical wires carry electrical impulses to power devices, nerves carry electrical impulses from the brain to various parts of the body to control muscle movement and convey sensory information. Both nerves and electrical wires rely on efficient transmission pathways to ensure proper communication within their respective systems.
