Difference Between Somatic and Visceral Reflex

Reflexes can either be visceral or somatic. Visceral reflexes involve a glandular or non-skeletal muscular response carried out in internal organs such as the heart, blood vessels, or structures of the GI tract. ... In contrast, somatic reflexes involve unconscious skeletal muscle motor responses.

What is a difference between visceral reflexes and somatic reflexes quizlet?

What is a difference between visceral reflexes and somatic reflexes? Visceral reflexes are unconscious while somatic reflexes are conscious. Visceral reflexes involve somewhat slower responses than somatic reflexes. Visceral reflexes are stereotyped whereas somatic reflexes are unpredictable.

What is a somatic reflex?

Somatic reflexes involve specialized sensory receptors called proprioceptors that monitor the position of our limbs in space, body movement, and the amount of strain on our musculoskeletal system. ... The effectors involved in these reflexes are located within skeletal muscle.

What is visceral somatic reflex?

Definition. Viscero-somatic reflex or reflexes usually occur when a diseased visceral organ initiates the transmission of information in afferent nerves (Fig. ... A schematic figure describing the events that occur when a visceral nociceptive stimulus elicits referred pain to the somatic structures, particularly muscle.

What are examples of somatic reflexes?

Examples: Knee jerk reflex and withdrawal reflex. Involve muscle groups and related joints, bones, tendons, ligaments and fascia; and are referred to as inter-joint reflex movements. Examples: Foot grasp reflex and Babinski reflex. Involve a combination of muscle groups and are considered inter-limb reflex patterns.

Do visceral reflexes require afferent neurons?

The afferent inputs to somatic and visceral reflexes are essentially the same, whereas the efferent branches are different. Somatic reflexes, for instance, involve a direct connection from the ventral horn of the spinal cord to the skeletal muscle.

What are two differences between somatic and autonomic reflexes?

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 are the 3 types of reflexes?

There are three common somatic reflexes discussed in most anatomy and physiology courses.

• Stretch (knee-jerk, patellar) reflex.
• Withdrawal (flexor) reflex.
• Crossed-extensor reflex.

What is the result of a somatic reflex?

The output of a somatic reflex is the lower motor neuron in the ventral horn of the spinal cord that projects directly to a skeletal muscle to cause its contraction. ... The other part of a reflex, the afferent branch, is often the same between the two systems.

Are somatic reflexes fast or slow?

It can be slow or fast. It uses higher and lower motor neurons, is variable and not stereotyped. A somatic reflex employs a reflex arc in which signals travel along the following pathways: 1.

What is an example of a visceral reflex?

Categories of Reflexes

Reflexes can either be visceral or somatic. Visceral reflexes involve a glandular or non-skeletal muscular response carried out in internal organs such as the heart, blood vessels, or structures of the GI tract. ... In contrast, somatic reflexes involve unconscious skeletal muscle motor responses.

What is the order of a visceral reflex?

Visceral reflexes involve a projection from the central neuron to a ganglion, followed by a second projection from the ganglion to the target effector.

What are the four components of a Monosynaptic somatic reflex arc?

The simplest example of a spinal reflex is the monosynapic reflex arc, having four components:

• A receptor (in this case, the muscle spindle).
• An afferent component (sensory input).
• A central component (spinal processing).
• An efferent component (motor output).
