me tell you how our body respond to energy drinks. BODY I. Energy drinks have caffeine a. Caffeine causes the following physiological effects: a.i. It stimulates the central nervous system (CNS) resulting in alertness. a.ii. It releases neurotransmitters (particularly acetylcholine) producing excitement. a.iii. It causes the pituitary gland to release adrenaline. a.iii.1. Adrenaline increases the heartbeat and causes the liver to release glucose into blood for higher energy. a.iii.2. Adrenaline

intended to present the fundamental biological principles of psychobiology/behavioral neuroscience to science undergraduate students. This course will cover the concepts of cellular and structural anatomy and physiology of the nervous system; the neurotransmitter systems and psychopharmacology; the functional anatomy of sensory systems‚ including vision‚ audition‚ olfaction‚ gustation and somatosensattion; and the motor system. Prerequisites: General Psychology (PSY1012) is a required prerequisite

act on the neurotransmitters responsible for carrying the vestibular signal from primary vestibular neurons. That is‚ these drugs seek to block the conduction of impulses from the semicircular canals and otolith organs‚ before these nerve impulses reach central vestibular structures (Smith & Darlington‚ 1996). The vestibulo-ocular reflex is a reflex eye movement‚ which is imperative in the control of balance. It functions to stabilize images on the retinas. Six primary neurotransmitters have been

Presynaptic: On the presynaptic dopaminergic neuron‚ lithium in acute administrations‚ inhibits the release of DA by binding onto the dopamine-specific (D1-D5) autoreceptors (Prasad‚ 2010). These autoreceptors serve as a mechanistic negative feedback loop that controls the release of DA and regulates its levels in the synaptic cleft. Lithium acts as an agonist on these autoreceptors and therefore inhibits the turnover of DA resulting in either increased reuptake or inhibited release from the presynaptic

UNIT 41- Assignment 2: Clinical psychology P1 Depression is a mental disorder often caused by the chemical imbalance of the brain. The symptoms vary from person to person when their diagnosed with depression. The symptoms are feeling hopeless and helpless‚ a lack of self-esteem‚ find everything less enjoyable‚ difficulty making decisions‚ having suicidal thoughts and harming one self and etc. Biological approach - Depression Depression can be common between families and past onto generations‚ however

M1 Nature is the genetic and biological influences on an individual and their development; it is based on genes and what is inherited from them. Nurture is the social‚ economic and environmental influences on an individual and their development; it based on personality and how behaviour is learnt. Determinism is the belief that you future is fixed and influenced purely naturally by what is genetically inherited or that your future is unpredictable and can change over time depending on choices made

The healthiness of coffee has been a topic of debate for many years. Being one of the most common drinks in the world‚ people have argued all sorts of positions in regards to its benefits or detriments to their health. Kris Gunnars’ article‚ “13 Health Benefits of Coffee‚ Based on Science” argues that coffee is indeed healthy‚ and provides thirteen reasons why. Jim Dillan’s article‚ “7 Negative Effects of Coffee & The Healthy Drink You Should Replace it With‚” argues the opposite‚ claiming that coffee

Further extraneuronal locations include among others lymphocytes‚ monocytes‚ and foetal tissue. 5-HT3 receptors modulate the release of neurotransmitters and neuropeptides like dopamine‚ cholecystokinin‚ acetylcholine‚ GABA‚ substance P‚ and serotonin itself. They have been demonstrated to be involved in sensory transmission‚ regulation of autonomic functions‚ integration of the vomiting reflex
