The marginal cost curve is U-shaped. For the first 4 Stuffed Amigos, marginal cost declines from $5 to a low of $1.50. However, for the production beyond 6 Stuffed Amigos, marginal cost increases.
Stretch Reflex. The stretch reflex is one of the simplest reflexes which contract a muscle that is being stretched. The stretch reflex is mediated through a monosynaptic arc and it contributes to the maintenance of steady standing posture and to coordinate muscle movement.
Best Answer: Monosynaptic reflexes such as the patellar reflex do not involve the brain since no intermediate (relay) neurone is involved. Other polysynaptic reflexes do involve the brain since a relay neurone is involved in the reflex arc which connects with longitudinal neurones running to and from the brain.You cannot suppress a monosynaptic reflex but you can suppress a polysynaptic reflex due the involvement of the brain.Source(s):eport Abuse. No it is not! The reflex arc works from the sensory neuron to the spinal cord, then directly to a motor neuron to perform the 'reflex.' The brain has no idea until the message then travels from the reflex action through another sensory neuron back to the brain to inform it of what just happened.
