The vestibulocochlear nerve (8th cranial nerve) is a sensory nerve. It is made up of two nerves, the cochlear, which transmits sound and the vestibular which controls balance.

The facial nerve is the 7th cranial nerve and carries nerve fibers that control facial movement and expression. The facial nerve also carries nerves that are involved in taste to the anterior 2/3 of the tongue and producing tears (lacrimal gland).Intracranial branchesGreater petrosal nerve, communicating branch with otic ganglion, nerve to stapedius, chorda tympaniExtracranial branchesPosterior au...

Abducent nerve: 6th cranial nerve : Gray's anatomy It's also known as the abducens nerve. This condition causes problems with eye movement. The sixth cranial nerve sends signals to your lateral rectus muscle. This is a small muscle that attaches to the outer side of your eye. When this muscle contracts, your eye moves away from your nose.

The trigeminal nerve is the part of the nervous system responsible for sending pain, touch and temperature sensations from your face to your brain. It's a large, three-part nerve in your head that provides sensation. One section called the mandibular nerve involves motor function to help you chew and swallow.each of the fifth and largest pair of cranial nerves, supplying the front part of the head...

The trochlear nerve is one of 12 sets of cranial nerves. It enables movement in the eye's superior oblique muscle. This makes it possible to look down. The nerve also enables you to move your eyes toward your nose or away from it.

The oculomotor nerve is the third cranial nerve (CN III). It allows movement of the eye muscles, constriction of the pupil, focusing the eyes and the position of the upper eyelid. Cranial nerve III works with other cranial nerves to control eye movements and support sensory functioning.

The optic nerve is a bundle of more than 1 million nerve fibers that carry visual messages. You have one connecting the back of each eye (your retina) to your brain. Damage to an optic nerve can cause vision loss. The type of vision loss and how severe it is depends on where the damage occurs.

The olfactory nerve is the first cranial nerve (CN I). It is a sensory nerve that functions for the sense of smell. Olfaction is phylogenetically referred to as the oldest of the senses. It is carried out through special visceral afferent nerve.

Subdural haematoma Separation of the arachnoid and dura mater requires little physical force, which means that damage to small bridging veins in the space can result in subdural haematoma after even relatively mild head trauma. In cases of chronic or subacute subdural haematomas, the accumulation is of relatively low pressure and seldom presents as a medical emergency; even sizeable accumulations...

Cavernous sinus : Gray's anatomy The cavernous sinus is part of the brain's dural venous sinus and contains multiple neuro-vasculatures. It is situated bilaterally to the sella turcica and extends from the superior orbital fissure anteriorly to the petrous part of the temporal bone posteriorly, and is about 1 cm wide and 2 cm long. The cavernous sinus is located on either side of the pituitary fos...

ll iabetes mellitus is the third leading cause lJ of death (after heart disease and cancer) in many developed countries. lt affects about 2 to 3% of the general population. The complications of diabetes affect the eye, kidney and nervous system. Diabetes is a major cause of blindness, renal failure, amputation, heart attacks and stroke. (The term diabetes, whenever used, refers to diabetes mellitu...

f nvironment constitutes the non-living (air, Lwater, land, energy etc.) as well as the living (biological and social) systems surrounding man. Environmental biochemistry primarily deals with the metabolic (biochemical) responses and adaptations in man (or other organisms) due to the environmental factors. A healthy environment is required for a healthy life which is however, not really possible o...

l-h" supply of oxygen is absolutely essential I for the existence of higher organisms. As the saying goes too much of even the best is bad. Very high concentrations of 02 are found to be toxic, and can damage tissues. The present day concept of oxygen toxicity is due to the involvement of oxygen free radicals or reactive oxygen species (ROS). In fact, the generation of reactive metabolites of 02 i...

The term detoxication or detoxificafion refers to fhe series of biochemical reactions occurring in the body to convert the foreign (often toxic) compounds to non-toxic or less toxic, and more easily excretable forms. Knowledge of the metabolism ol xenobiotics is essenfial for the understanding of toxicology, pharmacology and drug addiction. The bodV possesses the capabilitg to get rid of the forei...

prostaglandins and their related compounds- I prostacyclins (PGl), thromboxanes (TXA), leukotrienes (LT) and lipoxins are collectively known as eicosaniods, since they all contain 20 carbons (Creek : eikosi-twenty). Eicosanoids are considered as locally acting hormones with a wide range of biochemical functions. History : Prostaglandins (PCs) were first discovered in human semen by Ulf von Euler (...
