Properties of the Cardiac Muscle | Cardiovascular System | Biology

The physiological properties of the cardiac muscle are: 1. Rhythmicity 2. Excitability 3. Contractility 4. Conductivity. Property # 1. Rhythmicity/Automaticity/Chronotropism: In the myocardium, automaticity is the ability of the cardiac muscles to depolarize spontaneously, without external electrical stimulation from the nervous system. i. Primary Pacemaker: The sinoatrial node (SA node) is a group of cells positioned on the wall of [...]

Basic Properties of Cardiac Muscle (With Diagram) | Humans | Biology

The properties present in other muscle are also shown by the cardiac muscle. But it shows certain special features. 1. Rhythmicity: One of the main characteristic features of the cardiac muscle is that it can initiate its own impulse rhythmical­ly. This inherent rhythmical property is present throughout the cardiac muscle as evident from the electro-physiological studies of the single fibre [...]

Diagrammatic Representation of Classes of Cartilage | Human | Biology

In this article we will discuss about the diagrammatic representation of classes of cartilage in human body. Diagrammatic Representation of Hyaline Cartilage: Description: It is made up of cartilage cells and a clear homogeneous ground substance completely devoid of any fibrous (loose) tissue. (Fig. 1.44) Hyaline means glass and in fresh condition it appears as a translucent bluish- white mass. [...]
