Olfaction, Gustation, Vision, Equilibrium and Hearing.
Olfactory organs are located in the
Nasal cavity on either side of the nasal septum.
Olfactory organs are made up of :
Olfactory epithelium and lamina propria
Olfactory epithelium contains:
Olfactory receptor cells (supporting cells) and Basal cells (regenerative stem cells)
The lamina propria contains areolar tissues, blood vessels and nerves and
Olfactory gland (Bowman Glands)
This structure's secretions absor water and form thick, pigmented mucus.
Olfactory gland (Bowman Gland)
Olfactory reception occurs on the surface of the
Olfactory cilia
The olfactory cilia interact with receptors called
Odorant-binding proteins
These are chemicals that stimulate olfactory receptors
Odorants
The receptors involved in the binding of an odorant are
G proteins
For a smell to be perceived, the signal must reach the what of the cerebral hemisphere without unhibited intervening synapses.
The Olfactory Cortex
Axons leave the olfactory epithelium to reach the what of the Cerebrum, where the FIRST SYNAPSES occur.
Olfactory bulbs
What special sense has the only type of sensory info that reaches the cerebral cortex directly?
Olfactory
At least how many primary sense are known
50
Taste receptors are distributed over the superiorsurfaces of the tongue and adjacent portions of the what and what.
