Nerve fibres from olfactory receptor transmit their impulses to A while impulses from gustatory receptors are transmitted to B of cerebrum.Choose the option which gives the correct answer for A and B

Options

A. A Temporal lobe B Parietal lobe
B. Parietal lobe A Temporal lobe
C. A Frontal lobe B occipital lobe
D. A occipital lobe B Temporal lobe

Answer

To solve the question regarding where nerve fibers from olfactory receptors and gustatory receptors transmit their impulses in the cerebrum, we can break down the problem step by step.

### Step 1: Identify the function of olfactory receptors
Olfactory receptors are responsible for the sense of smell. They are located in the nasal epithelium and transmit signals related to odors.

**Hint:** Remember that olfactory receptors are linked to the sense of smell.

### Step 2: Determine where olfactory impulses are transmitted
The impulses from olfactory receptors are transmitted to the temporal lobe of the cerebrum. This area is specifically involved in processing smells.

**Hint:** Think about the location of the temporal lobe in relation to the sense of smell.

### Step 3: Identify the function of gustatory receptors
Gustatory receptors are responsible for the sense of taste. They are located on the tongue and are involved in detecting different flavors.

**Hint:** Recall that gustatory receptors are associated with taste sensations.

### Step 4: Determine where gustatory impulses are transmitted
The impulses from gustatory receptors are transmitted to the parietal lobe of the cerebrum, specifically in the area above the lateral sulcus, known as the postcentral gyrus. This area is involved in processing taste sensations.

**Hint:** Consider where taste sensations are processed in the brain and the specific lobe involved.

### Step 5: Summarize the findings
From the above steps, we conclude that:
- A (where olfactory impulses are transmitted) is the **temporal lobe**.
- B (where gustatory impulses are transmitted) is the **parietal lobe**.

### Final Answer
The correct answer for A and B is:
- A: Temporal lobe
- B: Parietal lobe
