Optic Nerve The optic nerve is located in the back of the eye and is also called second cranial nerve and cranial nerve II. the optic nerve is to transfer visual information from the retina to teh vision centres of the brain via electrical impulses. It is made up of ganglionic cells or nerve cells and consists of more than 1 million nerve fibres . Our blind spot is caused by the absence of specialised photosensitive/light-sensitive cells or photoreceptors; the part of the retina where the optic

IMPULSE CONTROL DISORDERS Many of the self-control disorders involve disturbances in the ability to regulate an impulse - an urge to act. People with impulse control disorders act on certain impulses involving some potentially harmful behavior that they cannot resist. Impulsive behavior in and of itself is not necessarily harmful; in fact‚ we all act impulsively upon occasion. Usually our impulsive acts have no ill effects‚ but in some instances they may involve risk. Consider the following

Handout Lab 5 - Cranial Nerves: Assessment of Functions INTRODUCTION The central nervous system (CNS) consists of the brain and the spinal cord. The CNS receives sensory information from other parts of the body or the body’s external environment and transmits motor information to other parts of the body by way of the peripheral nervous system (PNS). The PNS of the human includes 31 pairs of spinal nerves and 12 pairs of cranial nerves. Some nerves contain only motor nerve fibers (efferent fibers);

Neurophysiology and Learning September ‚ 2010 For the survival and progression of life as we know it‚ humans and non humans must rely on the fundamental aspects of learning. Learning is all around us‚ we experience it in our everyday lives‚ sometimes without even being aware of it. Theories of learning were introduced centuries ago‚ and being so important and of much significance in Psychology‚ they are continuously studied‚ revised and improved. A popular branch of the study of learning‚ Neurophysiology

Beauty and the Creative Impulse This essay‚ out of the three‚ was my favorite. The author had a lot of good points to support her thesis in which she stated that beauty is something integral of the world we live in; the earth that the Creator created. She also brought up the fact that sometimes we move so fast that we take beauty for granted. In this day and age‚ we live our lives in fast forward and we‚ almost literally‚ do not even attempt to stop or even slow down to smell the roses. She

Introduction A nerve is an enclosed bundle of axons found in the peripheral nervous system (Easton 13). It is the pathway for electrochemical nerve impulses‚ which pass along axons of the peripheral organs. A neuron is a cell in the nervous system which plays many critical tasks like receiving sensory signals from the external and internal environments. Moreover‚ neurons join together these sensory responses to produce and transmit motor responses as a result of changes in membrane permeability

a false truth to the word nerve. The courage it takes to have nerve is powerful‚ but having nerves is a weakness. A soldier in a battle needs confidence‚ and not worry or otherwise every action will be filled with doubt. The commander says‚ “No nerves‚ just have nerve out there.” The difference between the same word emphasizes the actual meaning of each word‚ creating it to be more heroic than a hero and braver than just the brave. One of the many definitions for nerve is “a person’s steadiness
