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.
From a clinical perspective, reflexes are extremely important. The stretch reflex is most important and is tested routinely. The flexion reflex is seldom tested, except in unconscious patients.Pain pathways usually are checked by testing for conscious sensibility to pin prick (see Chapter 5). Passive limb movement causes a stretch reflex in the muscles being stretched and their reflex contraction resists further movement of the limb. 2  The resistance is velocity sensitive, being greater the faster the limb is moved. 3  Clasp knife reflex.
