WebThe most commonly identified type of stretch reflex is the knee jerk reflex, where tapping the patellar tendon (i.e., the tendon located at the front of the knee) causes the foot to kick forward. This reflex is a type of deep tendon reflex tested during a neurological examination to identify abnormalities within this reflex arc. WebThe stretch reflex can be a monosynaptic reflex which provides automatic regulation of skeletal muscle length, whereby the signal entering the spinal cord arises from a change …
WebJan 17, 2024 · The stretch reflex is a monosynaptic reflex that regulates muscle length through neuronal stimulation at the muscle spindle. The alpha motor neurons resist … WebA stretch reflex is a type of muscle reflex, which protects muscle against increases in length that can tear and damage muscle fibers. The primary purpose of the patellar reflex – the stretch reflex of the quadriceps femoris muscle – is to prevent excessive stretching of the quadriceps. The patellar reflex is illustrated in Figure 1. Figure 1.

And a reflex is a response to a stimulus that doesn't require the involvement of consciousness. All reflexes have two parts. The first part is called the afferent part, afferent.

In a reflex, a stimulus to a sensor leads to a response in an effector. The neural pathway controlling the reflex is called the reflex arc .
