lifelong process fundamental to physical‚ cognitive‚ and emotional development. Building of the brain The functions of the brain and the reflexes derive from the central nervous system. The central nervous system is located in the brain and the spinal cord‚ which is a bundle of nerves running through the backbone. The nervous cord in spine then branches out into a peripheral network of nerves extending to every part of the body. The brain then sends nerve signals or commands to specific parts of

Introduction Three sources of sensory information are used by the nervous system in the maintenance of equilibrium. These are the eyes‚ proprioceptive endings throughout the body and the vestibular portion of the internal ear. In the development of the human body functions‚ the vestibular system is one of the first of the sensory integrative systems to be fully functional. The complete integration of the other sensory systems like vision and proprioception are continued throughout childhood

assumptions do biopsychologists make? Psychologists from the biological approach assume that behaviour and experiences are caused by activity in the nervous system of the body. The things that people think and feel‚ say and do are caused‚ one way or another‚ by electrochemical events occurring within and between the neurones that make up their nervous system‚ particular those in the brain. Many biopsychologists also agree that because the development of the brain is determined (at least partly) by the

How neurons communicate Neurons are the specialized cells which make up the body’s nervous system. These nerve cells process and transmit information from one part of the body to another. For example‚ if you were to touch a candle flame for more than an instant‚ pain nerves also known as receptors that are in your finger would send a message up through your hand and arm to the spinal cord and then to the brain. The brain which in turn records pain and sends the messages back down to various parts

Krabbe disease is a disorder inherited from parents‚ which destroys the myelin coat of nerve cells throughout the nervous system and the process is called demyelination. Demyelination inhibits the transmission of nerve impulses and that hinders the communication of the brain and the body and that results in disability (Mayo Foundation for Medical Education and Research‚ 2016). Dr. Knud. H.Krabbe diagnosed this disorder in 1916 (Arizona Board of Regents‚ 2015). Krabbe disease is a body recessive disorder

animal will be warm. This is because the animal doesn’t have the capability of regulating its body systems to keep a constant body temperature. When an ectothermic animal is cold‚ its heart rate will lower. When the animal is warmer‚ the heart rate will raise – as long as the temperature isn’t sufficiently high to harm the animal. (Campbell‚ 2005) Alcohol is a depressant. This means that body systems will slow down when alcohol is introduced. In particular‚ the heart rate will get consistently

Another example is the bionic ear which benefits people who have severe‚ profound or total hearing loss in either or both ear‚ also bionic limbs have

Every part of the system is comprised of neurons that collect and distribute information to make the body function. All neurons consist of four main components; a soma‚ dendrites‚ an axon and its terminals. The soma is a cell
