Question

How is human brain protected from mechanical injuries and shocks?

How is brain and spinal-cord protected against mechanical injuries?

Answer 1

1. The skull, cerebrospinal fluid, and meninges protect the brain against mechanical injuries and shocks.
2. Additionally, the blood-brain barrier prevents hazardous compounds from entering brain tissue.
3. The scalp, muscles, and connective tissues contribute to impact absorption.
4. Cranial nerves, reflexes, and defensive systems such as blinking and postural modifications help reduce potential injury.
5. The evolved shape and structure of the skull provide an optimal defence.
6. Wearing helmets is critical for preventing traumatic brain injuries, even with existing measures.

Answer 2

The skull, meninges, and cerebrospinal fluid protect the brain and spinal cord.
