Nose

Question 1

Olfactory epthelium cells

Answer 1

These are the sensory cell of the nose, the cells are ciliated at the surface which is a true true cilium and has nerve ending… Chemoreceptors

Question 2

Answer 2

Sensory fiber

Question 3

In the nose there is one part …….and one part ……….

Answer 3

Sensory and neuron

Question 4

Bowmans gland

Answer 4

Aka olfactory gland in the olfactory mucosa next to the receptor produces mucus that dissolves the stimulus or odorants, keeps the surface clean and covers the surface of the olfactory cell

Question 5

External nasal cavity

Answer 5

Vestibule…not use for smell…narisl …this for smelling

Question 6

The receptors are located on the

Answer 6

Cilia embedded in the membrane

Question 7

Signal transduction in the nose

Answer 7

The odorants in dissolved in the mucus, it makes contact with the cilium, activates a G protein, that bind to GTP inturn activating adenyl Cyclase converting ATP to cAMP.this opens up the Na channels, depolarization action potential, no release of neurotransmitter.

Question 8

The A.P leaves the nose by

Answer 8
