All of the following are true concerning reflex arcs EXCEPT
A.they involve a few neurons and directly enter and immediately leave the spinal cord
B.they are used to prevent harm
C.they are subconscious and automatic
D.they only use the PNS and not the CNS
Infants have a reflex called sucking reflex. One way to initiate this reflex is to touch the cheek of the infant. What is the specific reflex arc components in this reflex. What would be the classification of this reflex based on development, complexity, response and processing site. Would this be a ipsilateral or contralateral reflex?
Identify the Golgi tendon reflex (which is an innate reflex) as (a) spinal or cranial, (b) somatic or visceral, (c) monosynaptic or polysynaptic, and (d) ipsilateral or contralateral.
