Simplex Virus (HSV) infection involving the facial nerve and remains. It will affect about 1 in 60 people during their lifetime. Men and women are equally affected as are the right and left sides of the face. Pregnant women‚ especially during the third trimester are more prone to develop Bell’s palsy. The facial nerve‚ on its path from the brain stem to the face passes through a narrow bony canal in the base of the skull. The viral infection of the nerve is thought to produce inflammation and swelling

The action of lifting an arm can seem like a thoughtless movement‚ however‚ there is complex and intricate process that goes on within the human body to make that small movement happen. It involves bones‚ muscles‚ and nerves to complete this process‚ but it would not be able to start without a certain subconscious thought beforehand. Lateral abduction of the arm is defined as raising the humerus‚ radius‚ and ulna bones to ninety degrees‚ parallel to the ground‚ with the elbow extended‚ and wrist

separating the muscles into two osteofascial compartments: the anterior and the posterior compartments of the arm. The fascia merges with the periosteum (outer bone layer) of the humerus. The compartments contain muscles which are innervated by the same nerve and perform the same action.[citation needed] Two other muscles are considered to be partially in the arm: The large deltoid muscle is considered to have part of its body in the anterior compartment. This muscle is the main abductor muscle

microvilli that project through pores and chemically sense food. Gustatory receptor cells communicate with cranial nerve axon endings to transmit sensation to the brain. There are five taste sensations located on the tongue. They are sweet located front middle‚ sour located middle sides‚ salty located front side/tip‚ bitter located back‚ and umami located posterior pharynx. The cranial nerves that are associated with our taste sense are VII Facial located within the tongue‚ IX Glossopharyngeal located

Laboratory 3 Brainstem and Cranial Nerves Associated radiology modules: BRAINSTEM‚ CRANIAL NERVES Brainstem BLOOD SUPPLY The major blood supply to the brain is from two pairs of arteries‚ the vertebrals and the internal carotids. In general‚ the vertebrals supply the brainstem‚ the caudal diencephalon and the caudal and inferior cerebrum. The carotids supply the rostral thalamus and hypothalamus‚ the basal ganglia and the remainder of the cerebrum. Vertebral Branches. The vertebral arteries

Abstract Paralysis of a facial nerve (i.e. CN VII) is frequently diagnosed as Bell’s palsy. Patients who suffer from Bell’s palsy often experience unilateral loss of facial muscle function which presents as drooping of the eyelid and corner of mouth‚ impaired taste‚ hypersensitive hearing‚ and general loss of facial muscle function on the affected side of the face. Loss of nerve function occurs as a result of inflammation at the geniculate ganglion which causes nerve damage and may eventually lead

over would trigger the onset of glaucoma. When this pressure rises‚ it presses on and causes harm to the optic nerve. Any damage to the optic nerve would prevent visual information from being sent to the brain and therefore visual loss occurs. The exact pathophysiology of glaucoma is not fully comprehended but experts believe that the rise in pressure on the retina causes cells and nerve ganglions in the retina to die. Moreover‚ compression of small blood vessels occur in the retina and this deprives

Sciatic Pain Keyword: Back Pain Therapy What is the Sciatic Nerve? The sciatic nerve is the most massive single nerve in the body that bridges the spine and the lower extremities. It is fed by a total of five nerves originating from the spinal cord‚ transcending the length of the lower spine to the buttocks‚ branching out‚ and continuing to the foot. It innervates the skin and muscles of the lower limbs via the tibial and peroneal nerves. It also provides strength to the legs and is responsible for
