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]
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.
The nervous system of vertebrates (including humans) is divided into the central nervous system (CNS) and the peripheral nervous system (PNS). [16] The CNS is the major division, and consists of the brain and the spinal cord. [16] The spinal canal contains the spinal cord, while the cranial cavity contains the brain.
In the neuromuscular system, nerves from the central nervous system and the peripheral nervous system are linked and work together with muscles. [3] Synaptic transmission at the neuromuscular junction begins when an action potential reaches the presynaptic terminal of a motor neuron , which activates voltage-gated calcium channels to allow ...
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 ...
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.
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.

Neuromuscular drugs are chemical agents that are used to alter the transmission of nerve impulses to muscles, causing effects such as temporary paralysis of targeted skeletal muscles. Most neuromuscular drugs are available as quaternary ammonium compounds which are derived from acetylcholine (ACh). [ 1 ]
