However‚ most increased brain weight occurs because of myelination. (Page 246) Myelination is the process of coating the axon of each neuron with fatty coating called melin‚ which protects the neuron and helps it conduct signals more efficiently. Myelination begins in the brain stem and cerebellum before birth‚ but is not completed in the frontal cortex until late adolescence

sensitive to another stimulus is the ____________. a) resting period b) repolarisation c) depolarisation d) absolute refractory period 2. The part of a neuron that conducts impulses away from its cell body is called a(n) _______________. a) axon b) dendrite c) neurolemma d) Schwann cell 3.

indicated on the diagram; the dendrites are the receivers of information for that cell. The dendrites receive neurotransmitters from the synapses that connect to it and if enough are present‚ an action potential is caused which then travels down the axon to the terminal buttons also known as synapses. There are electrical and chemical synapses in the body although the vast majority are chemical. Electrical synapses are located in the retina and in some invertebrates such as crayfish (Pocock‚ G. &

SCI is an unexpected and devastating disease‚ which is caused by direct mechanical damage to the spinal cord and usually leads to motor and sensory dysfunction subject to the condition of injury. SCI is one of the major causes of death and disability in clinical situations. SCI brings enormous psychological and economic burdens to individual family as well as the whole society as a whole. (1‚2‚3‚4‚5) In the United States there are approximately 282‚000 people suffering from SCI and an average growth

specialised neurons that produce and release ADH into the body‚ ADH is manufactured in the cell body within these cells‚ lying in the hypothalamus. ADH flows through the axon into the terminal bulb in the posterior pituitary gland‚ where it is stored until needed. When neurosecretory cells are stimulated‚ action potentials are sent down their axons releasing ADH‚ which enters the blood capillaries running through the posterior pituitary gland then is transported around the body acting on cells of collecting

PSY 101 Review Sheet #1 Chapters 1-3 1. What does psychology study? Psychology is the scientific study of behaviors and mental processes. Behaviors include all outward or overt actions and reactions‚ mental processes include all internal covert activities of the mind. The goals of psychology are to describe‚ explain‚ predict‚ and control the behaviors and mental process of both human and animals. 2. Explain Structuralism. Structuralism is the study of the structure of the mind. It’s based
