Question

How is the brain protected from shocks and injuries?

Answer 1

Brain is the main and first controlling centre of the body, it instructs and guides all the body parts and thus, it must be shielded from any quiet injury and shocks and thus is roofed in bony coverings.

Complete Answer:
Brain may be a delicate organ which must be protected against injuries and shocks. The hard covering over the fragile organs helps in preventing any direct shock or injury to the organs.
The brain, master organ of the body is protected by the hard-bony covering called as skull or cranium and also its three thin membranes referred to as meninges. The spinal fluid (CSF) is present between the meninges and brain which acts as a shock and thus helps within the protection of the brain. Spinal fluid also plays a task in providing nutrition to the brain and it removes waste from the brain.

Brain consists of three parts:
1. Forebrain is the foremost part of the brain, and is the main thinking part and controls all actions done voluntarily by the body.
2. Midbrain: It's present between forebrain and hindbrain and cares with involuntary actions of the body.
3. Hindbrain: It's the last part of the brain which further continues to the medulla spinalis, it's three different regions called pons, medulla and cerebellum. It also controls involuntary actions like precision of selections, salivation, vomiting etc.
Spinal cord is present below the brain and extends to the backbone or spinal column (covering) cares with the control and regulation of the reflex actions.

Note: Brain and spinal both are related to one another and present very on the brink of one another, covering of brain is cranium which of medulla spinal is is spinal column, which shouldn't be confused with one another.
