Introduction Any damage occur in the central or peripheral nervous system due to toxins or artificial poisons called neurotoxicity, these poisons can stop or delay the action of nerves system in transmitting signal to different nerves in different body organs. There are to many substances that affect the nervous system and cause problems like insecticides,…

The vast majority of molecules in the brain and nervous system are made from amino acids. Growth hormone from the pituitary gland, dopamine from the substantia nigra area of the brain, and the aforementioned neurotransmitters, serotonin, GABA, epinephrine, norepinephrine, and glutamate are all amino acid based. If there are amino acid deficiencies in the brain,…

NERVOUS SYSTEM This is a collection of nerves and specialized cells called neurons that transmit signals between different parts of the body. This system transmits information by nerve impulses conducted from one area of the body to another. The nervous system transmits signals between the brain and the rest of the body including internal organs…

Our Nervous System Our nervous system is our bodys electrical wiring. It consists of complex nerves and neurons which carry messages throughout the different parts of our body (Mandal MD, 2019). What are the Parts of Your Nervous System? Our nervous system consists of two parts. One is the central nervous system, which includes our…

The zebrafish is an essential and widely used vertebrate model organism in many scientific researches, for example in developmental biology. This paper is mainly talking about specification of the zebrafish nervous system by nonaxial signals. There are two different signals, neutralizing and posteriorizing, which are regulating in the neurectoderm of the amphibian gastrula. However, in…

I. Introduction Paraneoplastic syndromes (PNSs) are unusual disorders that affect the function of the organ systems, due to the humoral secretion of tumors. The constituents secreted by the tumors consists mainly of hormones and cytokines that are capable of mimicking normal hormones which may affect other proteins flowing throughout the body. The endocrine, skin, blood,…

The human body is made up of biological systems that have specific functions for regular living. The nervous system controls both intentional activity (like cognizant development) and automatic activities (like breathing) and sends signals to distinctive parts of the body. The central anxious framework incorporates the brain and spinal rope. The central nervous system comprises…

The Brain The brain is protected by the skull and is made up of soft tissue, which includes grey and white matter, containing nerve cells, non-neuronal cells, and small blood vessels (Medical News Today, 2018). The brain controls the thoughts, memory, speech, and movements of the body, such as arms, legs, and organs. The brain…
