parts of nervous system ?
Answer (1)
The Human Nervous System is divided into two parts:Central Nervous System(CNS): The site of information processing and control. Peripheral Nervous System(PNS): All the nevers of the body that are in association with the CNS. ‣ The Central Nervous System is further divided into to parts:Brain: It is like the 'commander' of the body. It processes information, makes decisions, controls movements, stores memories, and manages emotions. Spinal Cord: It acts as a highway for messages between your brain and the rest of your body. It also plays a role in reflex actions without needing to involve the brain for quicker responses.‣ The Peripheral Nervous System is also divided into two parts:Somatic Nervous System: It transmits impluses from the CNS to skeleal muscles. Autonomic Nervous System: It transmits impluses from the CNS to the involuntary organs and smooth muscles.‣ The Brain is divided into three sub parts:Forebrain: Largest part of brain.Midbrain: A small but critical region that connects the forebrain to the hindbrain and plays a role in vision, hearing, and motor control.Hindbrain: It is responsible for managing essential, automatic functions needed for survival. ‣ The Somatic Nervous System is divided into two parts:Cranial nerves: These are 12 in pair and emerge directly from the brain or the brainstem. For example, Sensory nerves(optic nerve for vision and olfactory never for smell), Motor nerves(oculomotor nerve for eye movement) and mixed nerves(facial nerve for facial movements and taste). Spinal nerves: There are 31 pair of spinal netves and these nerves originates from the spinal cord. These nerves carry signals to and from the limbs, trunk, and other body parts. They are mixed nerves, meaning they have both sensory and motor functions.‣ The Autonomic Nervous System is divided into two parts:Sympathetic Nervous System: Activates 'fight or flight' responses during stress, increasing heart rate, breathing, and energy levels. Parasympathetic Nervous System: Promotes 'rest and digest', conserving energy, lowering heart rate, and aiding relaxation.Additional: You can also check my this answer to know what happens if there's a dysfunction in the nervous system!? https://brainly.ph/question/32424996
