In eukaryotes, there are two distinct types of cell division: a vegetative division, whereby each daughter cell is genetically identical to the parent cell (mitosis), and a reproductive cell division, whereby the number of chromosomes in the daughter cells is reduced by half to produce haploid gametes (meiosis).
At neuromuscular junctions, a neurotransmitter called as acetylcholine if found. Botulinum toxin inhibits the transmission of acetylcholine at the synaptic junctions. Botulin toxin acts at presynaptic junctions and blocks the release of acetylcholine, leading to paralysis.
Staying awake for days in a row will cause a person to become less alert and maybe even less aware of their surroundings.
Answer: D. NE producing cell bodies are found in widespread brain regions
Explanation:
Norepinephrine (NE) is a chemical in the body that exists naturally and acts as both a neurotransmitter and a stress hormone. When the brain perceives that there has been a traumatic occurrence, it is released into the blood as a stress hormone.
Norepinephrine is produced in the inner part of the adrenal glands which also produces adrenaline.
Hence, NE is only found in inner part of the adrenal glands and the correct option is D.
