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 [...]

Skeletal Muscle: Origin and Features | Tissues | Human | Biology

In this article we will discuss about:- 1. Distribution of Skeletal Muscle 2. Origin and Development of Skeletal Muscle 3. Features 4. Histological Structure 5. Blood Vessels, Lymphatics and Nerves. Distribution of Skeletal Muscle: The skeletal (voluntary and striated) muscle fibres are multinucleated cylindrical structures having a clear display of longitudinal and cross-striations. This muscular tissue is responsible for voluntary [...]
