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 [...]

Tonsil: Definition and Groups | Lymphatic Tissue | Human | Biology

In this article we will discuss about the definition and groups of tonsil which are found in human body with the help of suitable diagrams. Definition of Tonsil: There is accu­mulation of lymphoid tissue in the mucous membrane at the root of the tongue and at the surrounding of the pharynx, where nasal and oral passages unite, this lymphoid tissue [...]
