bouton

A swelling or thickening, especially on the skin.

axon 

The threadlike process of a neuron which conducts nerve impulses from the cell body to the neuron's ending (bouton) where it is transmitted via a synapse to another neuron, muscle or gland. Syn. nerve fibre (when it is sheathed). See neuron; synapse.

neuron

Structural unit of the nervous system consisting of the nerve cell body and its various processes, the dendrites, the axon and the ending (also called bouton, end foot or axon terminal). There are many types of neurons within the nervous system; some transmit afferent nerve impulses to the brain (e.g. those carrying information from the photoreceptors to the visual cortex), or to the spinal cord (e.g. those carrying information from the receptors in the skin to the spinal cord). They are called sensory neurons. Others transmit efferent motor nerve impulses to a muscle (e.g. those carrying information from the Edinger-Westphal nucleus to the sphincter pupillae and ciliary muscles). These are called motor neurons. Other neurons carry nerve impulses from one neuron to another (internuncial neurons). Note: also spelt neurone. See action potential; synapse.

The most conspicuous morphological difference between drive and modulator pathways lies on the size and shape of boutons, with smaller Bt associated with driving connections and larger ones associated with a modulatory role (37).

Multivariate discriminant statistical analysis shows that the linear density per millimeter of en passant boutons (Bpd) was higher than that of terminaux boutons (Btd) (*P<0.05, Bpd vs Btd; ANOVA-Tukey post hoc test) in all cortical target areas (A).
