The brain develops very quickly 75% by age 2. Describe the brain’s communication system and all of the individual parts associated with this. Neuron‚ axon dendrite‚ synapse‚ neurotransmitter and receptor. Also include transient exuberance. Neuron consists of a cell body and branching fibers. Neurons can communicate by firing chemical or electrical signals. It is excitable and can transmit and process information through electrical and chemical signals. Those signals occur in synapses. Synapses are

Describe how two businesses are organised (P3) I am going to talk about two organisations and how they operate. The organisations I am going to talk about are McDonalds and Chester Zoo. McDonalds is a fast food restaurant and its purpose is to provide the best and fastest customer service so in this way it will give the organisation a good reputation and help them to make more profit. [pic] This shows how stuff work in McDonalds. If there would be a problem with customers for example‚ then

neuron generate signals that open these voltage-gated channels? Dendrites and the cell body c. Opening of these channels causes the membrane to depolarize. (voltage change). 3. a. If the membrane reaches the trigger point‚ known as Threshold‚ what electrical potential will be generated? Action potential. b. During the depolarization phase‚ voltage-gated Na channels open and Na enters the cell. 4. What are the two processes that stop the potential from rising above +30 mV? a. Inactivation of

Anatomy review for the nervous system - Week 12 Study Guide 1. Distinguish the difference between neuron‚ neuroglial cells‚ Schwann cells‚ neurofibrils‚ and astrocytes. Neuron: masses of nerve cells in nervous tissue Neuroglial Cells: provide neurons physiological requirements (fill spaces‚ give support to neurons) Schwann Cells: larger axons of peripheral neurons enclosed in sheaths Neurofibrils: thin‚ long fibrils that run through body of neuron and extends to axon and dendrites; gives neuron

causes the user to have memory impairments. This is due to the loss of serotonin‚ which will be discussed later on. The reduction in serotonine affects the brains capacity to learn and remember. The memory impairment has shown to be detected up until two weeks after use‚ but habitual users who have become addicted show damage for up until seven years. Research has shown that the impairment is not due to withdrawal‚ but is heavily dose- dependent ("Ecstasy’s Legacy"). Another problem with Ecstasy

Organization of the human body Human anatomy and physiology – study of the structure and function of the human body. Anatomy- the scientific discipline that investigates the structure of the human body. Physiology – The scientific discipline that investigates the process of functions of living things. 6 Structural levels 1. Chemical level – atoms combine to form molecules 2. Cell level – Molecule form organelles 3. Tissue level – similar and surrounding material make up tissues

Brain Structure and Function Worksheet PSY 340 Brain Structure and Function Worksheet 1. Basal ganglia: This area consists of three clusters of neurons (these are called globus pallidus‚ caudate nucleus‚ and putamen). These are situated at the bottom of the brain that accounts for the involuntary movements like tremors. 2. Corpus collosum: This thick band of nerve fibers connects both of the brains hemispheres. 3. Temporal lobe: The two sides of the brain that is located on the sides
