Which of the following is mentioned in the passage about neuroendocrine cells?
The passage states that the neuroendocrine cells (a type of neuron) that secrete oxytocin are unusual even among neuroendocrine cells, in that they affect parts of the body far away from the brain.
The passage tells us that these areas of the hypothalamus contain neuroendocrine cells which produce oxytocin. This does not mean that neuroendocrine cells are the only components of these areas.
Although we know that oxytocin, which controls important maternal functions in mammalian females, is created by neuroendocrine cells, we do not know that producing it is their only function.
Although we may infer this to be true, this statement is not stated in the passage. The passage only tells us that unusual neuroendocrine cells affect areas far away from the brain.
This answer choice confuses the functions of both types of neurons. The passage states that neuroendocrine cells in the hypothalamus are those responsible for oxytocin, whereas other hypothalamic neurons connect to other neurons.
