Write short answers to the following questions:

1. The main organ of the nervous system is the brain.
2. A neuron is the basic functional unit of the nervous system, responsible for transmitting electrical and chemical signals.
3. The nervous system is classified into two main forms: the Central Nervous System (CNS) and the Peripheral Nervous System (PNS).
4. The cerebrum does not produce anything to protect the brain from minor injury; rather, the skull and meninges provide physical protection, and cerebrospinal fluid acts as a shock absorber.
5. Meninges are the three layers of protective membranes (dura mater, arachnoid mater, and pia mater) that surround the brain and spinal cord.
6. The function of the cerebellum is to coordinate voluntary movements, maintain posture, balance, and equilibrium.
7. The midbrain is located in the brainstem, between the forebrain and the hindbrain.
8. The spinal cord is a long, tube-like structure of nervous tissue that extends from the brainstem down the back, transmitting signals between the brain and the rest of the body.
9. The autonomic nervous system (ANS) is a part of the peripheral nervous system that controls involuntary bodily functions, such as heart rate, digestion, respiration, and blood pressure.
