Table 1 Natural language Aristotelian definitions of four different types of anatomical entities

cell nucleus

“Organelle which has as its direct parts a nuclear membrane and nuclear matrix” (Foundational Model of Anatomy, http://purl.org/sig/ont/fma/fma63840)

nucleated cell

“Cell which has as its direct part a maximally connected part of protoplasm.” (Foundational Model of Anatomy, http://purl.org/sig/ont/fma/fma67513)

neuron

“A neuron is a [eukaryotic] cell. It is part of the nervous system and consists of a soma that gives rise to neurites, which conduct electric excitation in a directed way. A neuron communicates with other cells via synapses. Most neurons synthesize and secret neuroactive substances.” ([58], p.23)

receptor cell

“A receptor cell is a neuron. It is part of the nervous system. In a signal transduction chain, it is the first neuron that converts an adequate stimulus into an electric signal.” ([58], p.34)

globuli cell

“A globuli cell is a neuron. It is part of a cluster of other globuli cells. It possesses a minute amount of cytoplasm and a nucleus containing condensed chromatin. The somata of globuli cells are densely packed and easily discernible … due to their small diameter” ([58], p.14)
