Synthesis of the neurotransmitter. This can take place in the cell body, in the axon, or in the axon terminal.Eg. acetylcholine; Storage of the neurotransmitter in vesicles in the axon terminal.
A cholinergic neuron is a nerve cell which mainly uses the neurotransmitter acetylcholine (ACh) to send its messages. Many neurological systems are cholinergic.Cholinergic neurons provide the primary source of acetylcholine to the cerebral cortex, and promote cortical activation during both wakefulness and rapid eye movement sleep.

There are two parts of the nervous system: the central nervous system (CNS) and the peripheral nervous system (PNS). General body functions are supervised by the central nervous system (CNS), which includes the brain and spinal cord. The PNS delivers motor signals to control body activities and receives sensory data from the CNS.
The PNS includes motor neurons, mediating voluntary movement; the autonomic nervous system, comprising the sympathetic nervous system and the parasympathetic nervous system and regulating involuntary functions; and the enteric nervous system, a semi-independent part of the nervous system whose function is to control the gastrointestinal system.
Neuroendocrinology is the branch of biology (specifically of physiology) which studies the interaction between the nervous system and the endocrine system; i.e. how the brain regulates the hormonal activity in the body. [1]
The WHO classification of tumours of the central nervous system is a World Health Organization Blue Book that defines, describes and classifies tumours of the central nervous system (CNS). Currently, as of 2023, clinicians are using the 5th edition, which incorporates recent advances in molecular pathology. [ 1 ]
GABA is an amino acid that is the primary inhibitory neurotransmitter for the central nervous system (CNS). It reduces neuronal excitability by inhibiting nerve transmission. GABA has a multitude of different functions during development and influences the migration, proliferation, and proper morphological development of neurons.
Post-junctional receptors also include some ionotropic receptors such as nicotinic receptors in the central nervous system (CNS) as well as the autonomic nervous system (ANS). Nonsynaptic junctional transmission is the only mode of transmission involving the varicosities that show no synaptic contacts that includes almost all nerve terminals ...
