Anatomy of the Nervous System Fig. Basic structure of a Neuron A neuron is the smallest unit of the nervous system. The neuron has a single cell body. The cell body is known as Soma. The long tail like structure connected with the cell body is known as Axon. The portion of the axon … Read more
Electrocardiography is the process of recording the electrical activity of the heart over a period of time using electrodes placed on the skin. It is abbreviated as (ECG or EKG). A normal ECG is shown below. Fig. 1 Electrocardiograph An electrocardiograph is a machine that is used to perform electrocardiography. Electrocardiogram It is the heart’s … Read more

The human body consists of 10 System viz. Skeletal System, Muscular System, Nervous System, Endocrine System, Respiratory System, Cardiovascular system, Lymphovascular system, Digestive System, Excretory System and Reproductive System. Different organs can work together to perform a common function and works as an integrated unit called organ system or body system. Body Systems … Read more
In the previous article, we discussed Bioelectric potential, action and resting potential. In this article, we will talk about heart Cardiac Conduction System. A heart has its own electrical system that is responsible for the continuous generation and A heart has its own electrical system that is responsible for the continuous generation and organised transmission of … Read more
Bioelectric potentials The ionic voltages produced as a result of the electrochemical activity of certain special types of cells are called as Bioelectric potentials. Resting & Action Potentials Our body is made up of different kinds of cells. The cell is the smallest unit of a living thing. The cell is surrounded by a … Read more
