Can brain damage affect the olfactory nerve?
Yes, brain damage can affect the olfactory nerve, which is responsible for the sense of smell. Damage to specific areas in the brain, such as the olfactory bulbs or frontal lobes, can lead to changes in the sense of smell or loss of smell altogether. In cases of traumatic brain injury or diseases that affect the brain, the olfactory nerve can be impacted resulting in olfactory dysfunction.
Impulses carried by the olfactory nerve are for the sense of?
Impulses carried by the olfactory nerve are for the sense of smell.
What happens in an olfactory reflex?
In an olfactory reflex, sensory neurons in the olfactory epithelium detect a smell stimulus. This information is then transmitted to the brain's olfactory bulb, which processes and interprets the smell signal. The brain then initiates a response, such as triggering memories, emotions, or behavioral reactions associated with the specific smell detected.
In what cells does a smell impulse begin?
A smell impulse begins in olfactory receptor cells located in the olfactory epithelium in the nasal cavity. These receptor cells detect specific odorants and send signals to the brain via the olfactory nerve.
What are smell receptors called?
They are called the olfactory cilia (microscopic hairs) located in the olfactory epithelium.
