The Human Endocrine And Nervous System

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 and spinal cord are the bodies central nervous system, the brain is the command centre for the body and the spinal cord is the pathway...

Poisons That Cause Disturbances In Nervous System

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, pesticides, mercury, lead, phenol, formaldehyde, chlorine, although there is naturally toxins in brain that cause toxicity like oxygen radicals that cause disorders in movement, autonomic...

Nervous System Organisation: Components And Structure

Components of the central and peripheral nervous systems. The central nervous system (CNS) consists of mainly brain and the spinal cord. The peripheral nervous system are nervous cells that sends signals to the CNS and allows us to respond to the stimuli detected by the surroundings. Peripheral nervous system divides into somatic nervous system and autonomic nervous system. The somatic nervous system contains nerves that carry sensory signals from the body to the CNS also nerves that carry motor signals...

Amino Acids And The Connection To The Nervous System

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, as well as cofactor deficiencies of Vitamin B6 and magnesium, then there can’t be adequate production of these protein molecules. If you add in mold,...

Nervous System: Structure, Food And Diseases

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 therefore controlling the ability to move, breathe, see and think and more. The nervous system is made of two main parts i. Central nervous system...

Nervous System: Components, Diseases And Treatment

Our Nervous System Our nervous system is our body’s 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 brain and spinal cord. The other is the peripheral nervous system which includes our nerves that are connected to our central nervous system, our sensory...

Clinical Anatomy And Physiology Of Peripheral Nervous System

Introduction: Peripheral nerves lesions are common in clinical practice and can be caused by a wide variety of diseases like trauma, neoplasms, infections, metabolic disease and chemical toxins such as lead therefore it is of paramount importance for a physician to know the basic structure of peripheral nerves. The peripheral nervous system (PNS) is considered a relatively simple part of the nervous system, compared to the central nervous system (CNS). It is composed of afferent sensory fibers and of efferent...

Specification Of The Zebrafish Nervous System

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 zebrafish, that signals more likely come from tissues. Nonaxial or axial mesendoderm caused different results. Thus, the signals from the organizer and the germring to...

Nervous System: Paraneoplastic Syndrome in Neuroblastoma Patients

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, and joints are some of the systems that are known to be most commonly affected by PNSs. Although it is rare, the nervous system also...

Disorders Affecting the Nervous and Musculoskeletal System

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 of nerves that interface each other portion of the body to the nervous system. The musculoskeletal system comprises of around 650 muscles that help in...
