Is the brain needed for the presece of spinal cord reflex activity? Why?
Answers
Answer:
The reflex arc
The impulse then travels out of the spinal cord along the motor neurones to the effector organ, a muscle, causing it to contract. Although these spinal reflexes do not need the brain for their action, sensory information is also sent to the brain via the ascending pathways.
Explanation:
heyy mate
the brain needed for the presence of spinal cord reflex activity because
carry sensory information from the receptor to the spinal cord, and then (b.) carry the response generated by the spinal cord to effector organs during a reflex action. The pathway taken by the nerve impulse to accomplish a reflex action is called the reflex arc.
It is important that reflexes occur without the need for thinking about them because there are things that happen to your body and forces acting in your body when you move that need to be responded to very quickly. Reflexes allow your body to react in ways that help you to be safe, to stand upright, and
and also
The path taken by the nerve impulses in a reflex is called a reflex arc. In higher animals, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. ... Reflexes do not require involvement of the brain, although in some cases the brain can prevent reflex action.
