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 [...]

Types of Epithelial Tissue: Simple and Compound | Human Body | Biology

According to shape and layer of cells, epithelial tissue which are present in human body is divided in two main types: 1. Simple Epithelial Tissue 2. Compound Epithelial Tissue. Type # 1. Simple Epithelium Tissue: I. Pavement (Squamous) (Fig. 1.20A): Description: It is composed of a single layer of large flat cells placed on a thin basement membrane. Distribution: It [...]
