Synthesis of Catecholamines | Nervous System |Animals

After reading this article you will learn about the synthesis of catecholamines. Norepinephrine (NE) or noradrenaline (NA) is the main transmitter at sympa­thetic neuro-effector junctions (except sweat glands and hair follicles) and CNS. Other neurotransmitters related to adrenergic transmission are dopamine (predominant in brain) and epinephrine (secreted by adrenal medulla). They are commonly named as catecholamines due to presence of [...]

After reading this article you will learn about the meaning and steps of Neurohumoral Transmission (NHT). Meaning of Neurohumoral Transmission (NHT): Neurohumoral transmission refers to the transmission of impulse through synapse and neuro-effector junction by the release of humoral (chemical) substances. The term 'conduction' stands for the passage of an impulse along an axon or muscle fibre. Almost all autonomic [...]
