CRANIAL NERVES, AREAS OF DISTRIBUTION
Olfactory receptors placed in olfactory region of nasal cavity (in superior nasal meatus). Receptors (1st neuron) associated with epithelial supporting cells. The peripheral process of olfactory cells carry the olfactory cilia and the central process form 15-20 olfactory nerves (1st cranial nerve), which pass through the foramens in cribriform plate and reach the olfactory bulb.
The axons of 2d neurons runs through the olfactory tract terminate in olfactory triangle and anterior perforating substance, where the bodies of the 3d neurons lie.
Plan of olfactory neurons.
Axons of the 3d neurons get the uncus and other part of limbic system, which is cortical olfactory analyser.Поділитися цим:
