What else can I help you with?
Does the impulse cross the neuromuscular junction when a muscle contracts?
No, the impulse traveling down the axon ends at the axon terminal but causes the axon terminal to release neurotransmitters. The neurotransmitters diffuse across the synaptic cleft causing the sarcolemma of the muscle to initiate its own impulse.
What muscle moves rhythmically?
heart This muscle is called cardiac muscle. Each cell can beat on its' own if in a sterile dish. If it touched another, they will beat together.
What generates its own electrical impulse spontaneously?
EKG
How many muscles in the heart?
Your heart is a cardiac muscle which means it never stops and works on its own.
What is a muscle found in the heart?
Cardiac muscle is the foundation of the heart. Cardiac muscle is an involuntary muscle meaning that it works on its own. You engage it like you would an arm or a let. The cardiac muscle has a built in system allowing it to be virtually fatigue resistant. This is because cardiac muscle is loaded with mitochondria which are a cell's power house or power plant.
Automaticity of the heart?
It is the ability of the heart to send an electrical impulse on its own.
Atrioventricular node at the bottom of the?
The heart beats regularly because it has it's own pacemaker. The pacemaker is a small region of muscle called the sinoatrial, or SA, node. It is in the upper back wall of the right atrium. The node triggers an impulse that causes both atrium to contract. Very quickly, the impulse reaches the atrioventricular, or AV, node at the bottom of the right atrium. Immediately, the atrioventricular node triggers an impulse that causes both ventricles to contract.
What is more complex a cell or muscle?
A muscle is more complex than a single cell because it is composed of many cells, specifically muscle fibers, along with various types of connective tissue, blood vessels, and nerves that work together to enable movement and function. Muscle tissue itself can be categorized into different types (skeletal, cardiac, and smooth), each with unique structures and functions. In contrast, a single cell, while intricate in its own right, operates independently and lacks the specialized coordination and integration characteristic of muscle tissue.
What does the mitochordoin do?
The mitochondrion is the powerhouse of the cell, responsible for generating energy in the form of ATP through the process of cellular respiration. It contains its own DNA and is essential for various cellular functions, such as metabolism and regulating cell death. Mitochondria are critical for providing the energy needed for cell survival and function.
Where does the atria located?
The Heart's own pace makerThe heart beats regularly because it has it's own pacemaker. The pacemaker is a small region of muscle called the sinoatrial, or SA, node. It is in the upper back wall of the right atrium. The node triggers an impulse that causes both atrium to contract. Very quickly, the impulse reaches the atrioventricular, or AV, node at the bottom of the right atrium. Immediately, the atrioventricular node triggers an impulse that causes both ventricles to contract.
Is there any risk for a pacemaker patient and electrical muscle stimulation by a chiropractor?
Yes there absolutely is. To put it in it's most basic terms, the heart has electricity running through it. When you get an EKG at the cardiologists office, those lines are measures of the electrical activity of the heart. The pacemaker fires an electrical impulse when it detects that heart did not fire an electrical impulse on its own. By adding electricity via electrical muscle stimulation, you will run the very high risk of confusing the pacemaker. Just don't do it.
What muscle in your body that moves on their own we call them involuntary muscle?
heart muscle
