Answer:
c. Damage to the primary (somatic) motor cortex results in the loss of both voluntary muscle control and all reflexive contractions.
Explanation:
The primary motor cortex is an area in the brain that is responsible for the control and regulation of activities that involves movement of the body as well as the postures they body takes which we also refer to as motor skills.
The primary motor cortex sends signals in the form of nerve impulses to the brain and this in turn helps in the maintenance of the motor skills that is carried out by the body.
Not only does the damage to the primary (somatic) motor cortex results in the loss of both voluntary muscle control and all reflexive contractions, it also causes other losses such as constant contraction of the muscles also know as spasticity, involuntary muscle contraction also referred to as clonus.
Answer:
In the mentioned scenario, norepinephrine and acetylcholine are the neurotransmitters, which would have been present at the higher concentrations in Sean's brain. Norepinephrine signifies to a neurotransmitter that plays an important part in dreaming, emotions, sleeping, attentiveness, and learning.
It also gets released in the bloodstream as a hormone, where it augments the rate of heart and causes the blood vessels to contract. Another neurotransmitter called acetylcholine signifies the chemical that is released by the motor neurons to instigate the muscles.
Answer:
