Final answer:
Cranial nerve I, which is called the olfactory nerve, is true. It is responsible for transmitting the sense of smell from the nasal cavity to the brain, where the olfactory cortex processes this sensory information.
Step-by-step explanation:
The statement that cranial nerve I is called the olfactory nerve is True. The olfactory nerve is responsible for conveying sensory information related to smell from the nose to the brain. The sensory receptor cells for the sense of smell are located in the olfactory epithelium in the nasal cavity. These cells detect chemicals that are volatile, often found in the air we breathe, and interpret them as different scents.
The olfactory cortex is the region of the brain associated with processing olfactory information. It is where received smells from the olfactory sensors are perceived and interpreted. This interpretation leads to the experiences of scent we recognize in our environment. Moreover, the olfactory system has a direct connection with the limbic system and hypothalamus that influences emotional responses and long-term memory linked with smells, without synapsing in the thalamus first, unlike other sensory modalities.
