The 5 special senses are:
|
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.
|
Pharynx and larynx
