considered a transmitter. These four steps include the synthesis of a transmitter substance‚ the storage and release of the substance‚ its interaction with a receptor in the membrane‚ and the removal of the transmitter form the synaptic cleft. The nervous system makes use of two types of neurotransmitters: small-molecule transmitters (acetylcholine‚ amines and A.A) and neuroactive transmitters(peptides) 2. Neurons have developed a sophisticated ability to regulate the synthesis‚ storage‚ release‚ and

eye burns‚ corneal damage‚ respiratory tract burns‚ digestive tract burns‚ and severe damage to the digestive tract. The human toxicity of 1-bromohexane includes; irritation to eyes and skin if contact occurs‚ irritation to lungs and respiratory system if inhaled‚ and skin inflammation along with itching or blistering. Some of the toxic effects that KPF6 has on humans are destruction of tissues in the membrane of the upper respiratory tract if inhaled‚ and burns on skin and eyes if contact occurs

An adolescent brain needs proper nutrition in order to develop and grow. Too little or too much nutrients will affect the nervous system and could possibly delay cognitive development. Under nutrition can cause delay in cognitive growth and development. If the brain does not have the adequate vitamins‚ minerals and micronutrients it does not have the ability to grow brain tissues and conduct nerve impulses correctly. This could lead to inappropriate behaviors and social adaption as well as decreased

Lorenzo’s oil consisting of oleic and erucic acids which reduces the level of VLCSFAs in the blood helped improve the nervous system of many boys and made them live longer. As proven in the movie‚ Lorenzo’s oil worked effectively as it helped Lorenzo recover and improved his nervous system. According to a study that was done‚ it showed the reduction of ALD symptoms development by 67% .In addition‚ the oil is effective as it reduces and prevents the inception

this neurotransmitter ’s role on behavior? Acetylcholine is a common neurotransmitter located in the central nervous system and the peripheral nervous system. Acetylcholine acts as a neuromodulator which engage in direct synaptic transmission between specific neurons. In the CNS acetylcholine plays a role in attention and arousal in the PNS it works as a major part of the autonomic nervous

In about 1% of cases‚ the virus enters the central nervous system‚ preferentially infecting and destroying motor neurons‚ leading to muscle weakness and acute flaccid paralysis. Different types of paralysis may occur‚ depending on the nerves involved. Spinal polio is the most common form‚ characterized by asymmetric
