In this instance, the cell that I’m referring to is a nerve cell. 3. Which type(s) of cells had tight junctions? The type of cells that had tight junctions were the myocyte cells (also known as muscle cells). 4. What is a lumen? A lumen is the inside space of a tubular structure, for example, the inside space of an artery or intestine.Actin filaments, usually in association with myosin, are responsible for many types of cell movements. Myosin is the prototype of a molecular motor—a protein that converts chemical energy in the form of ATP to mechanical energy, thus generating force and movement. The most striking variety of such movement is muscle contraction, which has provided the …Welcome to the Cell Structure simulation. In this simulation, you will learn about the principles of cell theory, what makes different types of cells unique, and the function of different cellular structures. The following is a list of relevant theory pages: Cell Theory. Eukaryotes vs. Prokaryotes.Summary. An action potential (AP) is a voltage change that propagates along the membrane of a myocyte ( muscle cell) or other cells such as a nerve cell. The AP is generated by the movement of positively charged ions, mainly Na+ and K+, across the plasma membrane. This generates an electrical current that travels down the length of the myocyte.

Myocytes are also called contractile cells because they contract to allow the heart to pump blood. Myocytes are different from skeletal muscle cells though, which get their action potential signals directly from neurons. Cardiac myocytes receive signal from pacemaker cells causing them to contract.Figure 19.21 Action Potential in Cardiac Contractile Cells (a) Note the long plateau phase due to the influx of calcium ions. The extended refractory period allows the cell to fully contract before another electrical event can occur. (b) The action potential for heart muscle is compared to that of skeletal muscle.

The myocyte network, coupled by gap junctions, is generally believed to be electrically isolated from fibroblasts in vivo. In culture, however, the heterogeneous cell types form functional gap junctions, which can provide a substrate for electrical coupling of distant myocytes, interconnected by fibroblasts only.
