In the crayfish's nerve cord, it is the combination of the two nerves that lead from the brain to form the ventral nerve cord which runs down the abdomen. It is important for sending signals from the ganglion to the appendages and muscles. While the rat's spinal cord it runs along the dorsal or back, rather than the front, and it is important for transferring neural signals between the brain and for the rest of the body.
Answer:
Over half the neurons of the brain are in a structure that constitutes only 10 percent of the brain’s total mass this structure is the cerebellum.
Explanation:
More than 50% of the brain's overall neurons are found in the cerebellum, although making up just about 10% of the brain's entire volume. The cerebellum has traditionally been thought to be a motor structure since cerebellar injury affects the position and motor function, as well as the bulk of the cerebellum's outputs, go to the motor neurons. The cerebellum does not originate motor orders; instead, it changes descending paths' control signals to improve the adaptability and precision of movements. Moreover, the cerebellum is responsible for many functions in the body including movements, vision, and balance, etc.
