Reflex Station Work in teams of 2 – the subject and the experimenter. The subject should sit on a desk or someplace where his/her legs can dangle freely. The experimenter should try to elicit the patellar reflex (also known as the knee-jerk reflex). Using the side of

The perfect example of the monosynaptic reflex is the knee-jerk or the patellar reflex. In this reflex, neuron I has its peripheral ending within the tendons of the quadriceps muscle . Once the tendon is excessively or suddenly stretched, neuron I detects that and informs neuron II that action is needed to avoid any injury to the tendon.

b) Draw a labelled diagram to show a reflex arc for the knee-jerk reflex when a doctor taps your knee. Use the key words in your diagram: stimulus, receptor, neurones, nerve impulse, effector, muscle, CNS, brain, spinal cord.

Reflex arc is a neural pathway that controls the reflex action. It is a pathway followed by nerves which carry sensory from the receptor to spinal chord and then carry the response of the spinal chord to the effector organs during a reflex action. Nerve cells have neurotransmitter storage vesicles going only in one direction and the receptors are in only one place. Therefore, the nerve ...

Mar 8, 2019 - Definition of reflex arc in the Medical Dictionary by The Free Dictionary 6 Brainstem The brainstem comprises the medulla, pons, and mid-brain. Like the spinal cord, with which it is caudally contiguous, it contains multiple long ascending and ...

There are five steps in a knee-jerk reflex arc as follows: A tap on the patellar tendon (tendon attached to the kneecap) is sensed by stretch receptors in the muscle (muscle spindles). The muscle spindle produces a pattern of nerve impulses that are conveyed along a sensory (afferent) nerve fiber, past its cell body in the dorsal root ganglion, and to its termination on a motor neuron.

The patellar reflex or knee-jerk (in American English knee reflex) is a stretch reflex which tests the L2, L3, and L4 segments of the spinal cord. Striking of the patellar tendon with a reflex hammer just below the patella stretches the muscle spindle in the quadriceps muscle..

10.Mar.2015 - Reflex arc of the knee: Reflexes are quick, involuntary reaction to a stimulus. Here we see the knee-jerk reflex. First, we see the somatic receptors in the muscle which pick up the stimulus. Then the afferent neuron carries the signal to the posterior horn of the spinal cord or brainstem. From here we reach the integrating center and the efferent neuron carries the muscle ...

ADVERTISEMENTS: Reflex action is a rapid, automatic action carried out without the intervention of the will of the animal. It is independent of the will of the animal. Marshall Hall first observed such action in the year 1833. During reflex action the impulse travels through a path known as reflex arc. A simple reflex arc …

Monosynaptic Reflex The simplest reflex arc: the monosynaptic (stretch) reflex. On entering the spinal cord the sensory axons often divide to form axon collaterals.So all axons distribute their information to multiple groups of post-synaptic cells.These

Because the integration center in this reflex arc has many synapses, it is a polynaptic reflex. And as already discussed, the sensory information will also travel to the brain to develop a conscious awareness of the situation such that conscious decision-making can take over immediately after the reflex occurs.
