Dilated Venous Plexus of the Hypoglossal Canal Mimicking Disease A diagnosis of hypoglossal canal lesions should be made with caution, as these lesions are quite rare, and vascular anomalies, such as those described, may mimic disease in this region. Previous Section Next Section. The hypoglossal (or anterior condyloid) canal is infrequently the site of disease.ummary: This article describes a case of prominent emissary veins of the hypoglossal canal protruding into the cerebellomedullary cistern mimicking disease, such as a nerve sheath tumor.

H-reflex to S1-root stimulation improves utility for diagnosing S1 radiculopathy The H-reflex on stimulation of the tibial nerve in the popliteal fossa is routinely used in the diagnosis of first sacral (S1) nerve-root radiculopathy.The H-reflex latency, however, is considered to lack sensitivity since a small change from the focal root pathology can be diluted in a relatively long reflex latency.n 1918, Hoffmann originally described the H-reflex occurring in calf muscles of humans on stimulation of the tibial nerve in the popliteal fossa. Hugon described a standardised technique for soleus H-reflex testing (Hugon, 1973).

Isolated unilateral idiopathic transient hypoglossal nerve palsy Idiopathic hypoglossal nerve palsy is a diagnosis of exclusion and all patients must be thoroughly investigated to look for a cause, particularly pathologies of the base of skull. It may be indicative of a demyelinating disease at a later stage and a repeat MRI of the brain in 5 years may be considered.

Cranial Nerve Injury Somatic motor - Movement of the tongue. One of the most commonly injured cranial nerves is cranial nerve I the olfactory nerve, which controls the sense of smell. Because our sense of taste depends primarily on smell, our sense of taste might be altered as well. Terms used to describe problems in this include:

Suprahyoid muscles 1 It is innervated by branches of the cervical plexus (C1-C2) accompanied by the hypoglossal nerve. 2  Stylohyoid muscle: extends from the styloid process of temporal bone to the body of hyoid bone. 3  In its distal part the muscle divides into two tendons. 4  The muscle is supplied by the facial nerve.

Facial nerve 1 The first branch of the facial nerve, the greater superficial petrosal nerve, arises here from the geniculate ganglion. 2  The greater petrosal nerve runs through the pterygoid canal and synapses at the pterygopalatine ganglion. 3  Post synaptic fibers of the greater petrosal nerve innervate the lacrimal gland.

- The hypoglossal nerve is the twelfth and last cranial nerve and supplies the tongue with motor control. It only has one catch: it receives hitch-hiking C1 nerve root fibres, which it distributes before reaching the tongue.

Foot drop The lesion can be in the L5 nerve root, sciatic nerve, common peroneal nerve, deep peroneal nerve, or superficial peroneal nerve (figure ⇓). The extent of the sensory or motor deficit depends on the location (or level), severity, and duration of the injury or compression.4) Deep peroneal nerve: weakness of foot dorsiflexion (tibialis anterior muscle), toe extension (extensor digitorum longus muscle and extensor hallucis longus muscle), foot eversion (peroneus longus and brevis muscles), and sensory loss in first web space.

The four cranial nerves involved in vision and movement of the eyes are the optic (I) nerve, oculomotor (III) nerve, trochlear (IV) nerve and the abducen (VI) nerve. The optic nerve is the sensory nerve for vision.

PCOM Anatomy 3 Spinal Nerves. Innervates posterior compartment muscles and skin of the posterior calf and sole of foot. At the knee, the tibial nerve gives off the sural nerve which is sensory to the postero-lateral leg. At the ankle, the tibial nerve divides into the medial and lateral plantar nerves which innervate most of the foot.

Nerves in the Foot The joints and muscles of the ankle and foot need to be maintained properly. Nerves provide the ankle and foot with sensation and also tell the muscles when to contract and when to relax. The ankle and foot require nerve supply to function properly. Here’s a look at the nerves that keep the foot and ankle kicking. Tibial nerve: This nerve is a branch of the sciatic nerve.
