ABSTRACT NEW DISCOVORIES FOR THE REGENERATION OF DAMAGED NEURONS (Possible cures and relief for millions of people) Normally‚ neurons in the central nervous system (the brain and spinal cord) cannot regenerate injured nerve fibers‚ limiting people’s ability to recover from brain or spinal cord injuries. Repair of the central nervous system and restoration of voluntary motor activity through axonal re-growth has long been considered impossible in mammals. Over the last decade‚ numerous attempts

The Five Sense Organs in Human Beings The sense organs — eyes‚ ears‚ tongue‚ skin‚ and nose — help to protect the body. The human sense organs contain receptors that relay information through sensory neurons to the appropriate places within the nervous system. Each sense organ contains different receptors. • General receptors are found throughout the body because they are present in skin‚ visceral organs (visceral meaning in the abdominal cavity)‚ muscles‚ and joints. • Special receptors include

Epithelia form the surface of the skin‚ line the various cavities and tubes of the body‚ and cover the internal organs. Subsets of Epithelia Epithelia that form the interface between the internal and external environments. Skin as well as the lining of the mouth and nasal cavity. These are derived from ectoderm. Inner lining of the GI tract‚ lungs‚ urinary

In this paper‚ I will be discussing the normal physiology of the basal ganglia‚ or basal nuclei‚ how the different structures within are involved with motor functions‚ and how dysfunctions within the basal ganglia lead to movement disorders. The basal ganglia are a group of interconnected subcortical structures composed primarily of the striatum‚ pallidum‚ substantia nigra‚ and the subthalamic nucleus. These structures span across the diencephalon‚ telencephalon‚ and the midbrain‚ and lie under

Intellectual disability (ID) is defined as the presence of incomplete mental development (Katz & Lazcano-Ponce‚ 2008). An intelligence quotient (IQ) score below 70-75 is commonly used to diagnose ID‚ and in affected children‚ observable deficits in linguistic‚ social‚ and cognitive skills reveal underlying delays in their development. ID may result from various developmental disorders such as Down and Fragile-X syndromes. Symptoms of ID in children include poorer long-term memory (LTM) than peers

Reflexes Laboratory Activity (12 points) 1. Amy has numbness of her pinky‚ ring finger‚ and medial surface of her right arm. After neurological testing‚ it is determined that she has a compressed spinal nerve on the right side. a. Which spinal nerve (what level) is affected? The level is C5-T1 cervical nerves. The specific spinal nerve would belong to the brachial plexus‚ the ulnar nerve. b. How did you determine/decide it was this level? The ulnar nerve branches off of the medial cord‚ which is

Bottom-up processing is the analysis that begins with the sense receptors and works up to the brain’s integration of sensory information. It describes the work of sensory receptors that change stimuli into neural messages that most usually reaches the brain. Sensation is the process by which our sensory receptors and nervous system receives stimulus energies from our environment. Bottom-up processing is akin to sensation. An example of bottom up processing occurs in vision. Bottom-up processing

Basically‚ it is the messenger cell responsible for receiving and transmitting information. Neurons are the information processing components of the brain‚ each part of the neuron is responsible for receiving and transmitting information. Each neuron please do use role

Pikachurin Pikachurin‚ also known as agrin-like protein (AGRINL) and EGF-like‚ fibronectin type-III and laminin G-like domain-containing protein (EGFLAM)‚ is a fibrous protein that in humans is encoded by the EGFLAM gene. Pikachurin is a dystroglycan-interacting protein which has an essential role in the precise interactions between the photoreceptor ribbon synapse and the bipolar dendrites. The binding with dystroglycan (DG) depends on several factors (glycosylation of DG‚ presence of divalent
