Quick Answer: What Are The 5 Deep Tendon Reflexes?

Are Deep tendon reflexes normal?

Deep tendon reflexes are normal if they are 1+, 2+, or 3+ unless they are asymmetric or there is a dramatic difference between the arms and the legs.

Reflexes rated as 0, 4+, or 5+ are usually considered abnormal..

What is the difference between stretch and tendon reflex?

The stretch reflex operates as a feedback mechanism to control muscle length by causing muscle contraction. In contrast, the tendon reflex operates as a negative feedback mechanism to control muscle tension.

What is a Polysynaptic reflex?

Any reflex with more than one synapse (1), not counting the synapse between neuron and muscle, and hence involving one or more interneurons. In humans, all reflexes except stretch reflexes are polysynaptic. Compare monosynaptic reflex. [ From Greek polys many + neuron a nerve]

What are different types of reflexes?

There are two types of reflex arcs:the autonomic reflex arc, affecting inner organs, and the somatic reflex arc, affecting muscles. When a reflex arc consists of only two neurons, one sensory neuron, and one motor neuron, it is defined as monosynaptic. Monosynaptic refers to the presence of a single chemical synapse.

What type of reflex is the knee jerk?

The response to the tap of the rubber hammer is called a knee-jerk reflex, but scientists and doctors call it a monosynaptic reflex—the simplest reflex that occurs inside your body [2].

What do deep tendon reflexes tell you?

The objective data obtained quite rapidly from testing deep tendon reflexes are correlated with motor and sensory findings to determine whether a problem lies in a specific peripheral nerve, specific nerve root, diffuse peripheral nerve, or spinal cord.

What are the 5 components a reflex test?

The reflex arc consists of 5 components:sensory receptor.sensory neuron.integration center.motor neuron.effector target.

What is a Myotatic reflex?

The stretch reflex or myotatic reflex refers to the contraction of a muscle in response to its passive stretching. When a muscle is stretched, the stretch reflex regulates the length of the muscle automatically by increasing its contractility as long as the stretch is within the physiological limits.

How many deep tendon reflexes are there?

five deep tendon reflexesThe reflex exam is fundamental to the neurological exam and important to locating upper versus lower motor neuron lesions. There are five deep tendon reflexes and a number of superficial and visceral reflexes covered here.

What will happen if we don’t have reflex action?

If the reaction is exaggerated or absent, it may indicate a damage to the central nervous system. Most reflexes go completely unnoticed because they don’t involve a visible and sudden movement. Body functions such as digestion or blood pressure, for example, are all regulated by reflexes.

What is a Monosynaptic reflex?

The monosynaptic stretch reflex, or sometimes also referred to as the muscle stretch reflex, deep tendon reflex, is a reflex arc that provides direct communication between sensory and motor neurons innervating the muscle.

What are the 6 deep tendon reflexes?
