🧠 The Human Brain – The Master Control Center of the Body
The brain is the main coordinating center of the human body. It receives information from different sense organs, processes it, and sends instructions to muscles and glands, enabling us to think, feel, learn, remember, and respond to our surroundings.
🔹 Three Protective Layers (Meninges):
• Dura Mater – The tough outermost layer that provides strong protection.
• Arachnoid Mater – The middle, web-like layer that cushions the brain with cerebrospinal fluid.
• Pia Mater – The delicate innermost layer that closely covers the surface of the brain and supplies it with nutrients.
🔹 Three Main Parts of the Brain:
🧠 Forebrain – The largest part; responsible for intelligence, thinking, memory, emotions, learning, voluntary actions, and interpretation of sensory information.
🧠 Midbrain – Acts as a relay center and controls visual and auditory reflexes, helping coordinate eye and head movements.
🧠 Hindbrain – Includes the cerebellum, pons, and medulla oblongata. It controls balance, posture, breathing, heartbeat, blood pressure, swallowing, and other involuntary activities.
