Final answer:
The tissues belonging to the postganglionic sympathetic system are chiefly responsible for releasing the neurotransmitter norepinephrine, which affects numerous physiological processes. The correct answer to the question is 'd. postganglionic sympathetic'.
Step-by-step explanation:
The tissues made up of postganglionic sympathetic cells can be characterized by the release of the neurotransmitter norepinephrine, except in the case of fibers that project to sweat glands and blood vessels associated with skeletal muscles, which release ACh. These postganglionic fibers project to various target effectors resulting in the modulation of organ activities. The adrenal medulla is also considered part of the sympathetic system as it is innervated by specialized preganglionic sympathetic fibers and secretes epinephrine and norepinephrine, functioning as hormones affecting wide-ranging body systems.
Regarding the provided options, the correct answer is d. postganglionic sympathetic, as these are the cells and fibers responsible for the described functions and neurotransmitter release mechanisms in the sympathetic division of the autonomic nervous system.
