Q1. What type of neurons are olfactory receptor cells?
- Bipolar neurons
- Multipolar lower motor neurons
- Purkinje cells
- Pseudounipolar spinal ganglion neurons
Q2. Which cells in the olfactory bulb provide major projection neurons to the olfactory tract?
- Schwann cells
- Purkinje cells
- Mitral cells
- Anterior horn cells
Q3. Where do olfactory receptor axons primarily synapse within the olfactory bulb?
- Cerebellar glomeruli
- Vestibular nuclei
- Olfactory glomeruli
- Geniculate bodies
Q4. At which structure does the olfactory tract divide into major olfactory striae?
- Optic chiasm
- Facial colliculus
- Interpeduncular fossa
- Olfactory trigone
Q5. Which olfactory stria carries the major projection toward primary olfactory cortical areas?
- Medullary stria
- Lateral olfactory stria
- Medial olfactory stria
- Stria terminalis
Q6. Which cortical region is a major component of primary olfactory cortex?
- Primary visual cortex
- Piriform cortex
- Precentral gyrus
- Primary auditory cortex
Q7. Which feature distinguishes the olfactory pathway from most other sensory pathways before reaching primary cortex?
- It crosses completely in the medulla
- It first enters the dorsal columns of the spinal cord
- It must first synapse in the lateral geniculate body
- It reaches primary olfactory cortex without an obligatory initial thalamic relay
Q8. Which part of the nasal cavity contains most olfactory epithelium?
- Floor of the nasal cavity only
- Superior region of the nasal cavity
- Inferior nasal meatus only
- Nasopharynx exclusively
Q9. What is unusual about mature olfactory receptor neurons compared with most neurons?
- They are lower motor neurons
- They normally divide continuously as mature neurons
- They are permanently confined to the olfactory bulb
- They can be replaced from basal cells
Q10. Which brain region is strongly linked to olfactory pathways and helps explain the close association between odors, emotion, and memory?
- Corticospinal tract
- Dorsal column nuclei
- Limbic system
- Primary motor cortex only
