Are stretch reflexes autonomic or somatic?
Somatic Reflexes. Somatic reflexes are involved in the reflex control of skeletal muscles and as such there are many different types of somatic reflexes including scratching reflexes, withdrawal reflexes and stretch reflexes and tendon reflexes.
What is a somatic stretch reflex?
Stretch Reflex In this reflex, when a skeletal muscle is stretched, a muscle spindle in the belly of the muscle is activated. The axon from this receptor travels to the spinal cord where it synapses with the motor neuron controlling the muscle, stimulating it to contract.
Why is the crossed extensor reflex classified as a contralateral reflex arc?
The crossed extensor reflex is contralateral, meaning the reflex occurs on the opposite side of the body from the stimulus. To produce this reflex, branches of the afferent nerve fibers cross from the stimulated side of the body to the contralateral side of the spinal cord.
Which is a somatic stimulus of a somatic reflex?
Somato-somatic reflex – occurs when somatic stimuli produce patterns of reflex activity in segmentally related somatic structures. For example, neurons in the spinal cord may receive abnormal levels of afferent activity from muscle spindles as a result of injury.
Are reflexes part of the somatic nervous system?
In addition to regulating the voluntary movements of the body, the somatic nervous system is also responsible for a specific type of involuntary muscle responses known as reflexes, controlled by a neural pathway known as the reflex arc.
What type of reflex is crossed extensor reflex?
withdrawal reflex
The crossed extensor reflex is a withdrawal reflex. The reflex occurs when the flexors in the withdrawing limb contract and the extensors relax, while in the other limb, the opposite occurs.
Which nerves are somatic?
The somatic nervous system consists of both afferent (sensory) and efferent (motor) nerves [1]. It is also responsible for the reflex arc, which involves the use of interneurons to perform reflexive actions. Besides these, there are thousands of other association nerves in the body.
