Which structures are reservoirs that store acetylcholine?
Synaptic vesicles within the presynaptic terminals of neurons are the main structures that store acetylcholine in the central nervous system. Additionally, vesicles in cholinergic nerve terminals at neuromuscular junctions also store acetylcholine.
The channels that transport sodium and potassium within the axon are called?
The channels that transport sodium and potassium within the axon are called voltage-gated sodium channels and voltage-gated potassium channels. These channels play a crucial role in generating and propagating action potentials along the axon.
What prevents acetylcholine from accumulating in the neuromuscular junction?
The presence of an enzyme called acetylcholinesterasethat degrades acetylcholine is what prevents an accumulation of the neurotransmitter and sustained muscle contraction. Acetylcholinesterase is an enzyme that can be found within the neuromuscular junction. Thus, when a nerve impulse causes the release of acetylcholine at the neuromuscular junction, there is a critical time in which the neurotransmitter can bind to receptors on the muscle before it is degraded.
What is the network of channels for collecting proteins?
The network of channels for collecting proteins is called the endoplasmic reticulum (ER). Proteins are synthesized on the ribosomes located on the surface of the rough ER, then transported and modified within the ER before being further processed and packaged for secretion or delivery to different cellular compartments.
What is acetylcholine and what is its function?
Acetylcholine is a neurotransmitter that plays a crucial role in transmitting signals in the nervous system. It is involved in various functions, including muscle contraction, regulation of heart rate, and modulation of cognitive processes like memory and attention. Acetylcholine acts at synapses between neurons and muscle cells, facilitating communication within the neuromuscular junction and central nervous system. Its proper functioning is essential for both voluntary and involuntary bodily activities.

Synaptic vesicles within the presynaptic terminals of neurons are the main structures that store acetylcholine in the central nervous system. Additionally, vesicles in cholinergic nerve terminals at neuromuscular junctions also store acetylcholine.
Within the axonal endings are many small vesicles containing a neurotransmitter substance called?
Acetylcholine
What is ' organization structures and communication channels within your organization '?
The organisation structures and communication channels within your organisation are memos, emails, telephone calls within the business etc
What is the definition of the word cholinergic?
The word cholingeric deals with biology and neurotransmitters. It means that a nerve can be activated by acetylcholine within the sympathetic and parasympathetic branches of the nervous system.
What neurotransmitter is released by the vagus nerve?
Acetylcholine is the primary neurotransmitter released by the vagus nerve. It plays a key role in controlling heart rate, gastrointestinal motility, and various other autonomic functions within the body.

What are small channels that radiate through the matrix of bone?
Small channels that radiate through the matrix of bone are called canaliculi. These canaliculi contain cellular processes that allow for communication and nutrient exchange between bone cells (osteocytes) located within the bone.
What channel does ABC come on in dish?
Your local Dish station depends upon where you live. Most local channels on Dish satellite are located within the channel 3-50 range.
Within a taste bud?
Ion channels are involved in detecting sour substances

Do ganglionic blockers increase the effects of vasodilators?
Neural transmission within the ganglia is cholinergic (acetylcholine) and the vasoconstrictive neurons release epinephrine at the blood vessels. So blocking neural transmission within the ganglia will reduce vasoconstriction.
