Trigeminal nerve The trigeminal nerve is the fifth of twelve pairs of cranial nerves enervating the face and head‚ and is denoted by the Roman Numeral V. It has three divisions which enervate the forehead and eye (ophthalmic V1)‚ cheek (maxillary V2) and lower face and jaw (mandibular V3). The trigeminal nerves function in sensing facial touch‚ pain and temperature‚ as well as controlling muscles used for chewing. The trigeminal nerve functions should be distinguished from the facial nerve (cranial

Neurophysiology Study Guide 1. Define "equilibrium potential". Why is the resting potential closer to the potassium equilibrium potential (EK+) than the sodium potential (ENa+)? The equilibrium potential is the point at which the force exerted on an ion by electrostatic and concentration gradient forces are balanced‚ and there is no net movement of that ion. The resting potential is closer to EK+ than ENa+ because the cell membrane is more permeable to

Within the body‚ there are billions of cells that are essential to living – these are called nerve cells. Nerve cells‚ also known as neurons‚ “are the basic information processing structures” (Stufflebeam). There are about 100 billion of these neurons in our nervous system and are the most essential cell in it. Located in brain as well as the spinal‚ there are different types of nerve cells; including: sensory neurons‚ motor neurons‚ and interneuron (Boeree). The neuron is a cell that is structured

normal rat and the surgically altered rats because the surgically altered rats didn’t have a thyroid or pituitary gland and therefore‚ the normal rat had a faster basal metabolic rate. The results turned out to be the way I predicted them to be. 3. T3 and T4 would be missing in the animal’s blood. 4. I would expect to see a decrease in hormone levels since the hypophysectomized animal cannot secret ay TSH. Part 2: 5. The normal rat’s BMR increased. 6. The thyroidectomized rat’s
