What involves of a cell membrane in cytoplasmic division in the animal cell?
During cytoplasmic division in animal cells, the cell membrane forms a contractile ring composed of actin and myosin filaments at the equator of the cell. This contractile ring constricts, causing the cell membrane to invaginate and eventually pinch off, resulting in two daughter cells.
What is aligned along the equator of the cell in metaphase?
Chromosomes are aligned along with the equator of the cell in metaphase.
Is it true that av nodal cells are poorly interconnected to contractile cells but they have bigger diameters?
Yes, atrioventricular (AV) nodal cells have fewer gap junctions which results in poor interconnection with contractile cells. However, the AV nodal cells have larger diameters compared to contractile cells, allowing them to conduct electrical signals efficiently.
What are three types of contractile cells in the body?
Myoepithelial Cells,Pericytes,Myofibroblasts
Indentation at the equator of a cell where it will divide?
The indentation at the equator of a cell is called the cleavage furrow. It forms during cytokinesis to separate the two daughter cells after the nucleus has divided. The cleavage furrow is generated by the contractile ring, which is composed of actin and myosin filaments that constrict the cell membrane.
What organelle is found in paramecia cells but not plant cells?
Contractile vacuole is found in paramecia cells but not plant cells. It helps in expelling excess water from the cell to maintain osmotic balance.

What contractile elements are in muscle cells?
sacromere

Contractile elements of muscle cells are?
actin myosin
Where is calcium stored in the contractile cells?
Sarcoplasmic reticulum
Are contractile vacuoles found in animal or plant cells?
Contractile vacuoles are primarily found in single-celled organisms, such as protists, that live in freshwater environments. They help regulate the water content of the cell by pumping out excess water to prevent it from bursting. Neither animal nor plant cells typically possess contractile vacuoles.

What is a contractile myoblast?
Myoblasts are a type of stem cells that exist in muscles.
What are the short thick branched contractile cells of the heart called?
Cardiocytes
