d

olfactory tract

nasal cavity

olfactory bulb

olfactory nerves

The axons of olfactory cells extend upward through the skull and converge inside a specialized region of the brain called the

• nasal vestibule

• gustatory cortex

• olfactory bulb

• olfactory epithelium

The primary olfactory cortex is located in which area of the brain?

(a)  

Different sensory organs utilize external stimuli and convert it to an electrical impulse. Gustation and olfactory receptors are

• chemoreceptors

• mechanoreceptors

• thermorecptors

• photoreceptors

Match the olfactory cell to the correct location and function

• Basal cells

• Location: epithelium Function: regenerate olfactory cells

• Olfactory cilia

• Location: epithelium Function: molecular detection

• Olfactory nerve

• Location: olfactory bulb Function: transmission to brain

• Bowman's gland

• Location: epithelium Function: Mucus

• Mitral or tufted cells

• Location: olfactory bulb Function: synapse with olfactory receptor cells

Which structure is directly responsible for detecting odor molecules?

(a)  

The olfactory bulb is located above this structure

(a)  

Reorder the following

• Dendrites of the olfactory receptor neuron are activated

• Odorant molecule is dissolved in mucus

• axons of the olfactory receptor synapse on the dendrites of the mitral cells in the glomeruli

• activation of G coupled proteins on the cell membrane result in opening of sodium or calcium channels

• olfactory receptor cell depolarizes sending an action potential
