  • Neuroplasticity Essay

    955 Words  | 4 Pages

    Neuroplasticity is the brain 's ability to reorganize itself by forming new neural connections throughout life. It allows the nerve cells in the brain, neurons, to compensate for injury and disease and to adjust their activities in response to new situations or to changes in their environment. Think of your brain like the leaves of a sunflower. Their leaves grow and move to face the sun throughout the day so that it is more effective in its functions to maintain life. This is quite similar to the

According to the NHS, its estimated that over 120,000 deaths are caused by smoking annually. All those cigarettes that you smoke then leads to horrible effects later in life; e.g. Cancer, Brain Damage, high blood pressure,

  • Synthesis Of Melatonin

    1725 Words  | 7 Pages

    INTRODUCTION Melatonin also known as N-acetyl-5-methoxy tryptamine is an indolic hormone produced by the Pineal Gland in animals [1]. Production of melatonin is regulated by photoperiod as its synthesis and secretion are repressed by light but induced at night in response to darkness [2].In humans it has been seen that a rise in synthesis of melatonin happens during night and vice versa during day, a circadian pattern. Moreover the mammalian “master circadian clock” located in the suprachiasmatic

  • Chemical Synapse Essay

    419 Words  | 2 Pages

    signal (AP) is transformed into a chemical signal (neurotransmitter) and thereafter is (re)turned back into an electrical one (AP). Thus the signal can move across the synaptic cleft via or as a neurotransmitter before it is turned back into an electrical signal (AP) at the receptor cell. This conversion process not only assures the inter-neural conduction of signals, but also their modulation (change). Depending on what kind of neurotransmitter is released and then docks at its postsynaptic receptors

  • Causes Of Parkinson's Disease

    473 Words  | 2 Pages

    common disease that affects the nervous system in the human body is Parkinson’s Disease. Parkinson’s is a progressive neurodegenerative disorder that causes neurons in the brain to deteriorate. These neurons, called dopamine neurons, produce a neurotransmitter called dopamine, which regulates and controls movement in the human body, and resides in an area of the brain called the substantia nirga. When the amount of dopamine reduces, neurons are lost; when this happens, the symptoms of Parkinson’s disease

  • Myasthenic Syndrome Case Study

    1623 Words  | 7 Pages

    Introduction The Lambert-Eaton myasthenic syndrome (LEMS) is an autoimmune disease. It is characterised by muscle weakness of the proximal lower limbs as a result of auto-antibodies produced against the voltage-gated calcium channels (VGCC) found on the presynaptic membrane of the neuromuscular junction(1). Most of the time, LEMS is classified as a paraneoplastic syndrome as it is often associated with cancer (small cell lung cancer in particular) (2, 3). One of the earliest descriptions of this

Key Words: Adrenal, ACTH, Hypophysectomy,Peroxidase-Ascorbate System, Progesterone Introduction: ACTH has a major role in the synthesis of progesterone which is known to be a precursor of several steroid hormones including androgens,estrogens and corticoids (Gorbman & Bern,1974).ACTH

  • Egg In Vinegar Lab Report

    738 Words  | 3 Pages

    CONCLUSION When you put an egg in vinegar, we see that the shell dissolves, but do you ever wonder why? An egg is made mostly out of calcium carbonate which reacts with an ingredient in vinegar, acetic acid. Acetic acid is about 4% of the vinegar and what breaks apart the solid calcium carbonate crystals. The bubbles we see, from the egg, is the carbonate that make carbon dioxide and the other calcium ions float free. This is the equation: CaCO3 (s) + 2 HC2H3O2 (aq) → Ca(C2H3O2)2 (aq) + H2O

  • Essay On Retina Detachment

    1354 Words  | 6 Pages

    Retinal detachment The retina is a complex layer of tissue that chemically converts light into electronic impulses and sends these impulses to the brain for analysis. It is made of layers of nerves, connecting cells known as neurons, supporting cells, and specialized cells known as rods and cones that do the actual conversion from light to chemicals that stimulate the nerves that transmit the impulse to the brain. Behind the rods and cones is a layer of pigment that absorbs light and helps the rods

  • Muscle Movement Essay

    414 Words  | 2 Pages

    The first step in the journey of muscle movement, is the motor neuron. The motor neuron provides Acetylcholine (ACh) which is crucial in muscle movement. Acetylcholine (ACh) is released from the synaptic terminals of the motor neuron. The ACh then travels across the synaptic cleft by way of diffusion. From the synaptic cleft, the ACh binds to the receptors located on the muscle fiber’s plasma membrane. After the ACh has found its way to the receptors and is bound to them, the muscle fibers become

  • Brain To Brain Interaction Essay

    1739 Words  | 7 Pages

    Introduction Brain to Brain Interface (BBI) has been made likely as the way brain cells interact with each other. A process is known as synaptic transmission in which cell to cell communication occurs, chemical signals passing among cells ensuing electrical spikes in the other or the receiving cell. Synaptic transmission formulates the base of all brain activity, these activities are motor control, memory, observation, and emotion. Since cells are linked together in a network, brain activity produces
