Is the knee jerk reflex somatic or autonomic?

Activity 1- Patellar reflex The patellar tendon reflex or knee-jerk reflex is a monosynaptic stretch reflex that assesses the nervous tissue between (and including) the L2 and L4 segments. It can be done by tapping the patellar ligament (just below the knee) with a reflex hammer.

What type of reflex is the knee-jerk?

Doctors will test reflexes by tapping the tendon just below the knee, and this causes the leg to kick out. This knee-jerk reflex is an example of a simple monosynaptic reflex.

Which reflexes are somatic?

In our discussion we will examine four major reflexes that are integrated within the spinal cord: the stretch reflex, the Golgi tendon reflex, the withdrawal reflex and the crossed extensor reflex.

What is meant by knee jerk reaction?

If you call someone’s response to a question or situation a knee-jerk reaction, you mean that they react in a very predictable way, without thinking.

What are autonomic reflexes?

Autonomic reflexes are unconscious motor reflexes relayed from the organs and glands to the CNS through visceral afferent signaling.

What is the order of somatic reflex?

perineurium. Which one of the following best describes the order of a somatic reflex? Somatic receptor -> afferent nerve fiber -> interneuron -> efferent nerve fiber ->skeletal muscle.

What is the difference between the autonomic and somatic?

The main difference between the somatic and autonomic systems is in what target tissues are effectors. Somatic responses are solely based on skeletal muscle contraction. The autonomic system, however, targets cardiac and smooth muscle, as well as glandular tissue.

What does the knee reflex test?

The patellar reflex, also called the knee reflex or knee-jerk, is a stretch reflex which tests the L2, L3, and L4 segments of the spinal cord.

Where did the saying knee jerk reaction come from?

The expression ‘knee jerk reaction’ comes from medicine, where the jerking motion the knee makes when tapped is called the patellar reflex. First seen in print in 1877, it became common in the early 20th century.

Which term is synonymous with a knee jerk reaction?

•automatic response (noun)

pavlovian response, involuntary impulse, gut reaction, absence of thought.

Which differentiates an autonomic reflex from a somatic reflex?

The main difference between the somatic and autonomic systems is in what target tissues are effectors. Somatic responses are solely based on skeletal muscle contraction. The autonomic system, however, targets cardiac and smooth muscle, as well as glandular tissue.

How are somatic and autonomic reflexes similar?

Autonomic nervous system function is based on the visceral reflex. This reflex is similar to the somatic reflex, but the efferent branch is composed of two neurons. The central neuron projects from the spinal cord or brain stem to synapse on the ganglionic neuron that projects to the effector.

Are reflexes sympathetic or parasympathetic?

The parasympathetic nervous system manages non-alarm state reflexes in the body. A general non-alarm state is engaged in the body when changes in the environment (or general environmental conditions) are familiar and non-threatening.
