A reflex arc, then, is the pathway followed by nerves which (a.) carry sensory information from the receptor to the spinal cord, and then (b.) carry the response generated by the spinal cord to effector organs during a reflex action. The pathway taken by the nerve impulse to accomplish a reflex action is called the reflex arc.
Triceps reflex — jerking of the forearm when the triceps tendon is hit with a tendon hammer, stimulating the C7 and C6 reflex arcs. Vagovagal reflex — contraction of muscles in the gastrointestinal tract in response to distension of the tract following consumption of food and drink. Vestibulocollic reflex; Vestibulo-spinal reflex
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. Many animals, most significantly humans, have been seen to have the patellar reflex, including dogs, cats, horses, and other mammalian species.
Reflex circuits vary in complexity—the simplest spinal reflexes are mediated by a two-element chain, of which in the human body there is only one, also called a monosynaptic reflex (there is only one synapse between the two neurones taking part in the arc: sensory and motor). The singular example of a monosynaptic reflex is the patellar reflex.
The stretch reflex (myotatic reflex), or more accurately "muscle stretch reflex", is a muscle contraction in response to stretching a muscle. The function of the reflex is generally thought to be maintaining the muscle at a constant length but the response is often coordinated across multiple muscles and even joints. [ 1 ]
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.
A spinal interneuron (relay neuron) forms part of a reflex arc Ib inhibitory interneuron: Found in lamina V, VI, VII. Afferent or Golgi tendon organ activates it. Cortex
A common example of this reflex is the cat righting reflex, which allows them to orient themselves in order to land on their feet. This reflex is initiated by sensory information from the vestibular, visual, and the somatosensory systems and is therefore not only a vestibulospinal reflex. [8]
