AP BIOLOGY

Detailed explanation-1: -Cerebrum. The largest part of the brain, the cerebrum has two hemispheres (or halves). The cerebrum controls movement, speech, intelligence, emotion, and what we see and hear.

Detailed explanation-2: -The frontal lobe is primarily responsible for thinking, planning, memory, and judgment. The parietal lobe is primarily responsible for bodily sensations and touch.

Detailed explanation-3: -Your cerebrum is inside of your skull, at the top and front of your head, and makes up the largest part of your brain.

Detailed explanation-4: -In humans, it is an organ of thought. While all vertebrates have a brain, invertebrates have either a centralized brain or collections of individual ganglia. Brains can be extremely complex. For example, the human brain contains more than 100 billion neurons, each linked to as many as 10, 000 others.

Detailed explanation-5: -Adult vertebrate brains can be subdivided into three major territories: forebrain (prosencephalon), midbrain (mesencephalon), and hindbrain (rhombencephalon) (Figure 1). Overall, the forebrain is the part that has changed the most in evolution, while the midbrain and hindbrain are relatively more conserved.
