They are neurones.
A Neuron.
Neurone or nerve cell
The layer of cells in the embryo that will develop into the epidermis and nervous system is the ectoderm. This outermost germ layer forms during embryonic development and gives rise to structures such as the skin, hair, nails, and the entire nervous system, including the brain and spinal cord.
These are the choices, it wouldn't let me put it in the main question. a. brain, spinal cord, organ system, nerve cell nervous tissue b. organ system, population of cells, nervous tissue, brain c. organism, organ system, tissue cell, organ d. nervous system, brain, nervous tissue, nerve cell e. organ system, tissue, molecule, cell
The neuron is the nervous cell that makes up about 90 percent of the nervous system. Neurons are the basic building blocks of the nervous system and are responsible for transmitting electrical and chemical signals throughout the body.

I'm not sure if you're asking if the nervous system can cause constipation or if being nervous can. The answer is yes either way. The nervous system is made up of neurons ( a cell, or nerve cell ). These neurons communicate to other cells via synapses which basically transmit that information to different parts of the body. So. lets say for instance when you get nervous you get constipated that is because you're brain sends signals through your nervous system to your entire body. That would include your bowels. How your bowels react is up to your own body. Hope that helps answer your question
