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

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

1. Human Nervous System- the part of a body that coordinates its voluntary and involuntary actions and transmits signals between different parts of its body. Mostly‚ it consists of two main parts‚ the central nervous system (CNS) and the peripheral nervous system (PNS). 2. Central Nervous System- the processing center for the nervous system. It receives information from and sends information to the peripheral nervous system. The two main organs of the CNS are the brain and spinal cord. The brain

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

Histamines and Antihistamines Neurotransmitters are chemical compounds that are central nervous system stimulants that mainly transmit nerve impulses with another cell or muscle. They are released in the synapse which chemically help signal one neuron to the next. One of the nerve cells that influence neurotransmitter release and stimulate the central nervous system pathway are histamines. It is specifically located in the nerve cells of the hypothalamus. All neurotransmitters structurally
