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.
The inverse stretch reflex or the Golgi tendon reflex completes the stretch reflex by a force-controlling feedback. The Golgi tendon organs monitor force in the tendons. Golgi tendon organs are in series with the muscle fibres-not parallel as the muscle spindles.
