What is the outermost part of the brain called?
.
The Cerebral Cortex
What connects the two hemispheres of the cerebral cortex?
The corpus callosum.
What are the four lobes of the cerebral cortex?
Frontal Lobe, Parietal Lobe, Occipital Lobe, and Temporal Lobe.
What is the primary function of the Frontal Lobe?
It is important for planning and implementing movement, as well as cognitive functions such as maintaining attention, speech, and decision-making.
What are the main functions of the Parietal Lobe?
Processing somatosensation (touch sensations) and proprioception (sense of body orientation in space).
Which lobe is primarily involved in vision?
The Occipital Lobe.
What structure in the Temporal Lobe is crucial for memory formation?
The hippocampus.
How is the gray matter of the spinal cord shaped?
It is butterfly-shaped.
What is the role of neurons at the back of the spinal cord?
They transmit information from the body to the brain.
