Fred's Bio 201 Nervous System Quiz

The Central Sulcus, also known as the fissure of Rolando, separates the frontal lobe from the parietal lobe. The Lateral Sulcus, also known as the Sylvian Fissure, separates the temporal lobe from the frontal and parietal lobes. The Parieto-Occipital Sulcus separates the parietal lobe from the occipital lobe.

In the brain, dark areas are typically composed of gray matter while light areas are composed of white matter.

The correct colors corresponding to brain regions are: Red=Frontal Lobe, Yellow=Parietal Lobes, Blue=Temporal Lobes, Green=Occipital Lobe, Purple=Cerebellum, Gray=Brain Stem.

The brain areas referred to as bluish and pinkish in the question are the Precentral Gyrus (bluish) and Postcentral Gyrus (pinkish). These specific areas are responsible for motor function (Precentral Gyrus) and sensory function (Postcentral Gyrus) in the brain.

The question is a humorous way of asking about a specific anatomical feature. The correct answer, the Lateral Cerebral Sulcus, is a prominent groove in the surface of the brain that separates the frontal and temporal lobes.

The correct answer is 'Sheep's brain'. The image shows a dissected brain that is characteristic of a sheep, not a cow, dog, or chicken.

The milky coating of a sheep brain is referred to as the Dura Mater, which is the tough outermost membrane covering the brain.

The correct answer is Arachnoid mater and Pia Mater. The arachnoid mater is a delicate membrane that lies between the dura mater and the pia mater. The pia mater is the innermost layer of the meninges, adhering closely to the surface of the brain.

The Longitudinal Fissure is the correct answer as it is the feature that runs along the top of the brain and separates the left and right hemispheres.

The grey matter in the transverse section is commonly known as the Cerebral Cortex, which is the outermost sheet of neural tissue in the mammalian brain.

The correct answer is Pons, which means 'Bridge' in Latin. It is a structure located in the brainstem that acts as a bridge between different parts of the brain.

The Medulla Oblongata is responsible for controlling several vital bodily functions such as breathing, heart rate, and blood pressure. It is located at the base of the brainstem. The Cerebellum is responsible for coordination and balance, the Hippocampus is associated with memory, and the Pons is involved in various functions including movements, sleep, and facial sensation.

The optic tract and optic chiasma are crucial components in the visual pathway, responsible for transmitting visual information from the eyes to the brain. The incorrect answers provided are not directly related to the specific structures mentioned in the correct answer.

The Corpus Callosum is a thick band of nerve fibers that facilitates communication between the two hemispheres of the brain. The Hippocampus is involved in memory formation and retrieval, the Cerebellum is responsible for coordination and balance, and the Amygdala plays a key role in processing emotions.
