THE ROLE OF LINGUAL LIPASE IN SALIVA FUNCTION
Lingual lipase is a water soluble enzyme that primarily catalyses the breakdown of fats and converts them to free fatty acids, monoglycerides and diglycerides. They play an important role in food digestion. Lingual lipase which was discovered in 1976 is a member of a family of digestive enzymes called triacylglycerol lipases, that use the catalytic triad of aspartate, and serine to hydrolyze medium- and long-chain triglycerides into partial glycerides and free fatty acids.
MOTILITY AND ASSOCIATED DISORDERS OF THE GASTRO INTESTINAL SYSTEM
ABSTRACT The Gastro intestinal system is vital for overall secretions, digestion, absorption, and movement within the tracts. Secretions involve release of fluids, chemicals and catalytic substances that facilitates digestion and related gastrointestinal tract (GIT) activities. Digestion involves hydrolysis of condensed products of carbohydrates, proteins and fats. Absorption involves movement of molecules across the GIT into the circulatory system. Carbohydrates are hydrolysed to monosacc...
THE DEVELOPMENT OF CARDIOVASCULAR SYSTEM AND RESPIRATORY SYSTEM
This concept involves the step by step processes associated with the formation and development of the human cardiovascular and respiratory system which together function to circulate oxygen and blood throughout the human body. These systems are complex in nature and their functionality is very vital for life.
THE PHYSIOLOGICAL ROLE OF OREXIN TO THE HUMAN SYSTEM.
ABSTRACT Orexins are recently discovered neuropeptides synthesized by neurons located in the posteriolateral hypothalamus. There are about 10,000 to 20,000 of these neurons in the hypothalamus and their axons extend throughout the brain and spinal cord where their receptors are located. The word Orexin is a Greek word reflecting orexigenic (appetite stimulating) activity of hormone. There are two types of Orexin – Orexin-A and Orexin-B – and these are essentially the same as hypocretin...
THE CONTRIBUTIONS OF PRESYNAPTIC ALPHA-2 (α2) RECEPTORS AND PROSTAGLANDIN E-SERIES TO THE CONTROL OF SYMPATHETIC NERVOUS ACTIVITY.
ABSTRACTThe Sympathetic nervous systems (SNS) is an efferent division of the Autonomic nervous system (ANS) with neurons which anatomically originates in the central nervous system (CNS). It has a short preganglionic neuron which comes from the thoracic and lumbar regions (T1 to L2) (also termed, thoracolumbar outflow) of the spinal cord. The axons of the postganglionic neuron extend from these ganglia to the tissues that they innervate and regulate. In most cas...
PUBERTY: Role Of Endocrine System In The Onset And Regulation Of Puberty; Disorders Associated With Puberty.
AbstractThe endocrine system is a system of glands, each of which secretes a type of hormone directly into the bloodstream to regulate the body. Many of the body's hormones influence growth, such as growth hormone, thyroxine, insulin, and corticosteroids (all of which influence growth rate), leptin (which alters body composition), and parathyroid hormone, 1,25-dihydroxy-vitamin D, and calcitonin (all of which affect skeletal mineralization). However, the key hormone in growth is GH which is...
FACTORS THAT CAN UPREGULATE AND DOWNREGULATE DIGESTION AND ABSORPTION OF CARBOHYDRATE
Digestion is the breakdown of complex food substances into simple and absorbable form by the aid of enzymes using a process known as hydrolysis. Carbohydrate basically are divided into three: Polysaccharides (example Starch), Disaccharides (Sucrose and Lactose), and monosaccharides (Fructose, Galatose and Glucose). Almost all the carbohydrates of the diet are either large polysaccharides or disaccharides, which are combinations of monosaccharides bound to one another by condensation (Guyton...
CLINICAL ASPECT OF SPINAL MOTOR SYSTEM - THE BROWN SEQUARD SYNDROME
Brown-Séquard syndrome, also known as Brown-Séquard's hemiplegia and Brown-Séquard's paralysis, is a loss of sensation and motor function (paralysis and anesthesia) that is caused by the lateral hemisection (cutting) of the spinal cord. This may be seen most often in the cervical (neck) or thoracic spine. Other synonyms are hemiparaplegic syndrome, hemiplegia ethemiparaplegiaspinalis, and spinal hemiparaplegia. Brown-Séquard syndrome is characterized by loss of motor function (i.e...
CELL TO CELL SIGNALLING - HOW CELL COMMUNICATE WITH EACH OTHER TO PROMOTE AND SUSTAIN LIFE
Cell to cell signaling refers to the transfer of information from one cell to another. This is also called cell signaling or intercellular communication. The ability of cells to perceive and correctly respond to their microenvironment is the basis of development, tissue repair, and immunity as well as normal tissue homeostasis. Errors in cellular information processing are responsible for diseases such as cancer, autoimmunity, and diabetes. The cells of the body communicate with each other ...
BLOOD FLOW MEASUREMENT
Blood is a specialized connective tissue in fluid form that flows through the entire body of a person or animal. Blood flow is the continuous circulation of blood through the cardiovascular system to body tissues and organs. An adequate amount of blood supply is necessary for the proper functioning of all body organs. This is vital as the blood carries and supplies body tissues and organs with its daily metabolic requirements while it also gets rid of any waste arising from tissue metabolis...
