The nervous system is composed of the central nervous system and the peripheric nervous system. The function of the nervous system is to send signals from one cell to others, or from one part of the body to others [1]. The term signal can refer to anything from electrical impulses to chemical messengers, to just…
Tissues are made of cells that share morphological features to achieve specific functions within the body. They are 4 types of tissue in our body: 1. What Is a Connective Tissue? Connective tissue provides structure, support, protection, and connection to other tissues and organs of the body [1]. 1.1. What Are the 3 Types of…
They are several diseases where the body’s immune system attacks the cells of the central nervous system (brain and spinal cord): 1- What Is an Autoimmune Disease? An autoimmune disease is when the body develops an abnormal immune response against certain parts of the body leading to their destruction. An abnormal autoimmune response is associated…
There are several foods that contain substances that stimulate the body’s central nervous system (CNS). These foods include: However, before discussing foods that are rich in stimulants of the central nervous system (CNS), it is important to introduce the CNS and the different classes of stimulants. 1- What Is the Central Nervous System?

Prolonged stress or chronic stress promotes susceptibility to diseases and infections such as sepsis, endocarditis, respiratory viral infections, meningitis, and other central nervous system infections. This type of stress significantly affects the immune system by raising the levels of catecholamine (adrenaline and dopamine), glucocorticoids (e.g., cortisol), and suppressor T cells, which suppress the immune…
Mitochondria are cellular organelles that produce about 90% of the chemical energy (ATP) that is required for the survival of cells. This energy is produced through an enzymatic respiration cycle known as the citric acid cycle, or the Krebs cycle. These powerhouse structures possess their own DNA and transcriptional and translational machinery within the cells. They…
