Question

the central nervous system (cns) is made up of the and the. it is responsible for controlling survival, emotions, memory, and higher - level thinking.
the hindbrain is the area that develops and is responsible for survival functions. the controls heartbeat and breathing, while the keeps us alert and helps us fall asleep. the assists with breathing, heart rate, digestion, and rem sleep. the helps control balance, movement, and coordination.
the limbic system is considered the of the brain. the is the brains relay station, sending messages to different areas (except the sense of smell). the controls emotions like fear and anger. the regulates hunger, thirst, sex drive, and rage. the is the \master gland\ that triggers other glands to release hormones. the is responsible for forming new memories.
the cerebrum is divided into the left and right. the lobe controls vision, while the lobe controls hearing and smell. the lobe is responsible for touch, taste, and processing sensory input. the lobe is responsible for higher - level thinking, organization, moral decision - making, and personality.
the cns is essential because of, the brains ability to change and adapt after injury or experience. without the cns, humans could not survive, process information, or function in the world.

Explanation:

The central nervous system (CNS) consists of the brain and spinal cord. The hindbrain has parts like medulla oblongata (controls heartbeat and breathing), pons (keeps us alert and helps sleep), reticular formation (aids in various functions), and cerebellum (balances movement). The limbic system is the emotional center, with thalamus as a relay, amygdala for emotions, hypothalamus for drives, pituitary as the master - gland, and hippocampus for memory. The cerebrum has lobes (occipital for vision, temporal for hearing/smell, parietal for touch/sensory, frontal for higher - level thinking). Neuroplasticity is the brain's ability to change.

Answer:

The central nervous system (CNS) is made up of the brain and the spinal cord. It is responsible for controlling survival, emotions, memory, and higher - level thinking.
The hindbrain is the area that develops first and is responsible for survival functions. The medulla oblongata controls heartbeat and breathing, while the pons keeps us alert and helps us fall asleep. The reticular formation assists with breathing, heart rate, digestion, and REM sleep. The cerebellum helps control balance, movement, and coordination.
The limbic system is considered the emotional center of the brain. The thalamus is the brain's relay station, sending messages to different areas (except the sense of smell). The amygdala controls emotions like fear and anger. The hypothalamus regulates hunger, thirst, sex drive, and rage. The pituitary gland is the "master gland" that triggers other glands to release hormones. The hippocampus is responsible for forming new memories.
The cerebrum is divided into the left and right hemispheres. The occipital lobe controls vision, while the temporal lobe controls hearing and smell. The parietal lobe is responsible for touch, taste, and processing sensory input. The frontal lobe is responsible for higher - level thinking, organization, moral decision - making, and personality.
The CNS is essential because of neuroplasticity, the brain's ability to change and adapt after injury or experience. Without the CNS, humans could not survive, process information, or function in the world.
