1.Cerebrum or cerebral hemispheres-the rat’s is smooth and the human is very convoluted and folded. Do you think this makes a difference and if so how would it make a difference ?2. Cerebellum has three parts or lobes. What are the functions of the three lobes?
3.Medulla oblongata connects the brain with the spinal cord. It functions to regulate what ?
4.Spinal cord relays information back and forth between the two nervous systems called what ?
5. Corpus callosum is white and connects the two hemispheres. Why do you think it is white?
Explanation / Answer
Hi!!!!! Hope this answer will help you :) 1. The cerebral hemispheres form the largest part of the human brain and are situated above ... As a rule, the smaller the cerebrum, the less convoluted the cortex. The cortex of a rat or mouse is almost completely smooth. ... The cerebral cortex in humans is so large that it overshadows every other part of the brain.. 2. The cerebellum, or "little brain", is similar to the cerebrum in that it has two hemispheres and has a highly folded surface or cortex. This structure is associated with regulation and coordination of movement, posture, and balance. * Frontal Lobe- associated with reasoning, planning, parts of speech, movement, emotions, and problem solving * Parietal Lobe- associated with movement, orientation, recognition, perception of stimuli * Occipital Lobe- associated with visual processing * Temporal Lobe- associated with perception and recognition of auditory stimuli, memory, and speech. The medulla oblongata controls autonomic functions, and relays nerve signals between the brain and spinal cord. It is also responsible for controlling several major points and autonomic functions of the body: * respiration – chemoreceptors * cardiac center – sympathetic, parasympathetic system * vasomotor center – baroreceptors * reflex centers of vomiting, coughing, sneezing, and swallowing. 3. central nervous system (CNS), peripheral nervous system (PNS, 4. It connects the left and right cerebral hemispheres and facilitates ... It is the largest white matter structure in the brain,
