By contrast, postganglionic fibers in the parasympathetic division are cholinergic and use acetylcholine as a neurotransmitter. In the sympathetic nervous system, the postganglionic neurons of sweat glands release acetylcholine for the activation of muscarinic receptors.
The International Space Station (ISS) is made up of multiple materials. Lightweight metals, plastics, and carbon fibers make up the majority of the state.

made up of fascicles (bundle of cells) covered in perimysium. made up of muscle fibers (cells) covered in endomysium. myofibrils (made of molecular motors) make up each muscle fiber and sarcomeres are contained in each myofibril. blood vessels line in between the connective tissue coverings in between the fascicles. sarcolemma is the cell membrane of muscles with invaginations (t tubules) that go into the cells.
