What does contractile impulse mean?
Contractile impulse refers to the electrical signal that initiates contraction in muscle cells. In cardiac muscle, this impulse originates from the sinoatrial (SA) node, propagating through the heart to coordinate rhythmic contractions. In skeletal muscle, it results from signals transmitted by motor neurons. Overall, contractile impulses are crucial for the effective functioning of both cardiac and skeletal muscles.
What is neural impulse?
A neural Impulse is a spike of electrical activity.
Structure that carries the heart electrical impulse into the ventricle?
The structure that carries the heart's electrical impulse into the ventricles is called the bundle of His. It is a collection of specialized muscle fibers located in the walls of the heart's chambers that conducts the electrical signal from the atrioventricular node to the ventricles, initiating their contraction.
What kind of impulse tells the heart to pump blood?
an electrical impulse
What causes an electrical impulse to move down a neuron?
An electrical impulse, or action potential, moves down a neuron due to the rapid influx and efflux of ions across the neuron's membrane. When a neuron is stimulated, sodium channels open, allowing sodium ions to enter, which depolarizes the membrane. This change in voltage triggers adjacent sodium channels to open, propagating the impulse along the axon. The process is facilitated by the myelin sheath, which insulates the axon and allows for faster transmission through saltatory conduction.
How do you convert electrical impulse in to electrical energy?
if it acts on a charged particle
What structure in the heart delays the electrical impulse momentarily to allow the ventricles to fill completely?
The structure in the heart that delays the electrical impulse momentarily is the atrioventricular (AV) node. This delay allows the ventricles sufficient time to fill with blood from the atria before they contract. By ensuring optimal timing for ventricular contraction, the AV node plays a crucial role in effective heart function.
What are electrical impulse sensors called?
Electrodes
Agent or factor capable of initiating nervous impulses is?
A neuron is the primary agent that is capable of initiating nervous impulses. When a stimulus is received, specialized structures in the neuron, called dendrites and axons, allow for the transmission of electrical signals to communicate and trigger nervous impulses.
Where does the electrical impulse of the heart get lost in the body?
the skin
What generates its own electrical impulse spontaneously?
EKG
Do The neurons transfers information in the forms of an electrical impulse?
yes they do
