A spinal reflex is a rapid, involuntary response to a stimulus. Tala has an issue with motor areas of her brain. Will her spinal reflexes still function?
A
No, because the motor areas control all movement.
B
No, because an issue with the motor areas is likely to prohibit the sensory areas from working.
C
Yes, because the sensory and association areas can initiate movement when motor areas are injured.
D
Yes, because spinal reflexes are involuntary, and the motor areas are responsible for voluntary movement.
Verified step by step guidance1
Understand the concept of a spinal reflex: A spinal reflex is an automatic response to a stimulus that does not require input from the brain. It involves a direct pathway through the spinal cord.
Identify the role of motor areas in the brain: The motor areas of the brain are primarily responsible for voluntary movements, which are conscious and intentional actions.
Differentiate between voluntary and involuntary movements: Spinal reflexes are involuntary, meaning they occur without conscious thought and do not require the motor areas of the brain.
Consider the independence of spinal reflexes: Since spinal reflexes are mediated by the spinal cord and do not require brain input, they can still function even if there is an issue with the motor areas of the brain.
Conclude that spinal reflexes will still function: Despite Tala's issue with the motor areas of her brain, her spinal reflexes will continue to operate because they are involuntary and do not depend on the motor areas responsible for voluntary movement.
