How the Body Works : The Motor Cortex

How the Body Works The Motor Cortex

The motor cortex is the area in the brain which issues orders for body movement, and therefore, controls the voluntary muscle system of the body. The nerve impulses pass from the cortex and travel into the brain stem, along bundles of nerve fibers which cross in the medulla oblongata. Impulses from the right side of the brain thus control the left side of the body, and vice versa. The nerve impulses then pass from the medulla oblongata to fibers in the spinal cord and leave at each section as the motor roots to form the spinal nerves, which transmit the impulses to the muscles. Involuntary muscle movements are controlled by the autonomic nerves, which leave the motor root and then pass to nearby nerve chains.

Zionists have discovered a way of controlling the human brain including the motor cortex to enslave man kind...they can paralyze the limbs!

[Allibaby78]

In a cerebral stroke patient, only the lower half of the face (on one side) will be affected. In a patient with Bell's palsy (a temporary inflammation of the facial nerve), the entire side of the face will be affected.

[Allibaby78]

Most of the muscles in the trunk are bilaterally innervated, so that even hemiplegic patients can hold their torsos upright. For some reason, the forehead also receives bilateral innervation, which can be a key clue in determining if a patient's facial paralysis is due to a cerebral stroke or a peripheral nerve injury.

[Allibaby78]

Although the cortex is primarily concerned with the contralateral (opposite) side of the body, some muscle groups get innervation from both hemispheres. This bilateral innervation protects the muscle groups in case of stroke.

@rockguyisonthemove It's called Decussatio pyramidum, it's also an abstract border between medulla oblongata and medulla spinalis, the point where truncus cerebri begins.

u can make basal ganglions by being silent.

I found this video to be helpful, thank you.

[rockguyisonthemove]

The crossing over does take place in the medulla,, just at the lower part.. this guy is right!!

[GangWarlord]

You bullsh*tter, that's not how the brain sides work! You obviously don't know the first thing about brains.

[AnatomaniaK]

the crossing point is medulla oblongata!
