Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If you are right handed, what side of the brain controls that?
A
Motor cortex of left hemisphere
B
Motor cortex of right hemisphere
C
Sensory cortex of left hemisphere
D
Sensory cortex of right hemisphere
Explanation: 

Detailed explanation-1: -The brain is divided into symmetrical left and right hemispheres. Each hemisphere is in charge of the opposite side of the body, so your right brain controls your left hand. The right hemisphere also takes in sensory input from your left side and vice versa.

Detailed explanation-2: -Stimulating the left primary motor cortex would cause the right side of the body to move. The messages for movement and sensation cross to the other side of the brain and cause the opposite limb to move or feel a sensation. The right side of the brain controls the left side of the body and vice versa.

Detailed explanation-3: -The left cerebral hemisphere controls movement of the right side of the body. Depending on the severity, a stroke affecting the left cerebral hemisphere may result in functional loss or motor skill impairment of the right side of the body, and may also cause loss of speech.
