What is the difference between myogenic and neurogenic muscle?
The myogenic heart refers to the contractile part of it, while the neurogenic heart refers to the highly specialized muscle cells that no longer contract but instead conduct impulses in the heart.
Why is the transmission of nerve impulses often referred to as an electrochemical event?
Myogenic conduction
How are muscle cells formed by stem cells?
In postnatal muscle, skeletal muscle precursors (myoblasts) can be derived from satellite cells (reserve cells located on the surface of mature myofibers) or from cells lying beyond the myofiber, e.g., interstitial connective tissue or bone marrow. Both of these classes of cells may have stem cell properties. In addition, the heretical idea that postmitotic myonuclei lying within mature myofibers might be able to re-form myoblasts or stem cells is examined and related to recent observations for similar post-mitotic cardiomyocytes. In adult hearts (which previously were not considered capable of repair), the role of replicating endogenous cardiomyocytes and the recruitment of other (stem) cells into cardiomyocytes for new cardiac muscle formation has recently attracted much attention. The relative contribution of these various sources of precursor cells in postnatal muscles and the factors that may enhance stem cell participation in the formation of new skeletal and cardiac muscle in vivo are the focus of this review. We concluded that, although many endogenous cell types can be converted to skeletal muscle, the contribution of non-myogenic cells to the formation of new postnatal skeletal muscle in vivo appears to be negligible. Whether the recruitment of such cells to the myogenic lineage can be significantly enhanced by specific inducers and the appropriate microenvironment is a current topic of intense interest. However, dermal fibroblasts appear promising as a realistic alternative source of exogenous myoblasts for transplantation purposes. For heart muscle, experiments showing the participation of bone marrow-derived stem cells and endothelial cells in the repair of damaged cardiac muscle are encouraging.
What kind of cells are plant cells?
All plant cells are eukaryotic cells
What are some types of human cells?
blood cells, white blood cells, sperm cells, brain cells.
What is the definition for myogenic?
myogenic refers to the contraction of cardiac muscle cells.
Is toad's heart is myogenic?
Yes, a toad's heart is myogenic.
What is the difference between myogenic and neurogenic muscle?
The myogenic heart refers to the contractile part of it, while the neurogenic heart refers to the highly specialized muscle cells that no longer contract but instead conduct impulses in the heart.
Is Human heart is myogenic or neurogenic?
In the human heart, contraction is initiated by a special modified heart muscle known as sinoatrial node. It is located in the right atrium. The SA node has the inherent power of generating a wave of contraction and controlling the heart beat. Hence, it is known as the pacemaker. Since the heart beat is initiated by the SA node and the impulse of contraction originates in the heart itself, the human heart is termed myogenic. The hearts of vertebrates and molluscs are also myogenic.
What does Myogenic Mean?
The word myogenic means that the origin is in the muscles. This is in order to differentiate between nerve and muscle origin.
Why do you call your heart myogenic?
The heart is known to be myogenic because the muscles that contract the heart through a pulse are themselves called myocytes.
What is myogenic heart?
So the word "myogenic" refers to a type of cell, a myocyte, that is able to contract by itself, without any nerve stimulation (aka signals from the brain). So if someone refers to a myogenic heart, that person just means that the heart is able to beat on its own, without you willing it to beat. The myocytes within the heart regulate the heart's contractions instead of your brain doing it.
Is cockroach heart myogenic or neurogenic?
I think, heart of a cockroach is myogenic. It can stop anytime. That's why even when the heart stops doesn't mean cockroach is dying.
The movement of electrochemical impulses in the myocardium?
myogenic conduction
What muscle has coordinated activity to act as a pump?
cardiacheart, the activity is co ordinated via myogenic cells, and also by the nerves going to the sino atrial node.
The movement of electrochemical impulses in the myocardium is called?
Myogenic Conduction
What mechanism is the general tendency of vascular smooth muscle to contract when stretched?
myogenic
