Introduction:
Oral-pharyngeal reflexes demonstrate a wide range of complexities due to their intricate synaptic pattern. Most of the reflexes are protective in nature such as preventing aspiration. These reflexes in oral cavity affect the muscles and can be evoked either in isolation or in combination in order to achieve a specific response. Certain sensory inputs induce an entire motor behavior pattern as seen in lingual hypoglossal reflex.
Materials And Methods:
A case report depicting this reflex have been presented. To our knowledge, this is the first case documented in a living human. Along with this, cadaveric studies have been also done in fifteen specimens.
Results:
Extralingual anastomosis between lingual nerve and hypoglossal nerve were found in six specimens.
Conclusion:
Hereby, we present a clinical paper of this unusual phenomenon which has not been documented in the literature.

01:26The Micturition Reflex
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating...

01:22Somatic Spinal Reflexes
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...
