Transcript: Medical Background Bone Structure Bone Introduction In the human body at birth, there are approximately 270 bones present; many of these fuse together during development, leaving a total of 206 separate bones in the adult, not counting numerous small Sesamoid bone. The largest bone in the body is the femur or thigh-bone, and the smallest is the stapes in the middle ear. Bone Cells Bone Cells Remodeling Remodeling Approximately 10% of the skeletal mass of an adult is remodeled each year. Bone is constantly being created and replaced in a process known as remodeling. This ongoing turnover of bone is a process of resorption followed by replacement of bone with little change in shape. Remodeling This is accomplished through osteoblasts and osteoclasts. Cells are stimulated by a variety of signals, and together referred to as a remodeling unit. The purpose of remodeling is to: 1- Regulate calcium homeostasis 2- Repair micro-damaged bones from everyday stress 3- Shape the skeleton during growth. Remodeling The action of osteoblasts and osteoclasts are controlled by a number of chemical enzymes that either promote or inhibit the activity of the bone remodeling cells, controlling the rate at which bone is made, destroyed or changed in shape. The cells also use Paracrine Signaling to control the activity of each other. For example, the rate at which osteoclasts resorb bone is inhibited by Calcitonin and Osteoprotegerin (OPG). Calcitonin is produced by parafollicular cells in the thyroid gland, and can bind to receptors on osteoclasts to directly inhibit osteoclast activity. Remodeling Osteoprotegerin is secreted by osteoblasts and is able to bind RANK-L, inhibiting osteoclast stimulation. Osteoblasts can also be stimulated to increase bone mass through increased secretion of osteoid and by inhibiting the ability of osteoclasts to break down osseous tissue. Increased secretion of osteoid is stimulated by the secretion of growth hormone by the pituitary, thyroid hormone and the sex hormones (estrogens and androgens). Remodeling These hormones also promote increased secretion of osteoprotegerin. Osteoblasts can also be induced to secrete a number of cytokines that promote reabsorption of bone by stimulating osteoclast activity and differentiation from progenitor cells. Vitamin D, Parathyroid hormone & Stimulation from osteocytes induce osteoblasts to increase secretion of RANK-ligand and interleukin 6, which cytokines then stimulate increased reabsorption of bone by osteoclasts. Remodeling These same compounds also increase secretion of macrophage colony-stimulating factor by osteoblasts, which promotes the differentiation of progenitor cells into osteoclasts, and decrease secretion of osteoprotegerin. Calcium Ca++ Calcium Ca++ Measurement in blood Calcium Foods rich in calcium include dairy products, such as yogurt and cheese, sardines, salmon, soy products, kale, and fortified breakfast cereals. Because of concerns for long-term adverse side effects, including calcification of arteries and kidney stones, both the U.S. Institute of Medicine (IOM) and the European Food Safety Authority (EFSA) set Tolerable Upper Intake Levels (ULs) for combined dietary and supplemental calcium. Calcium Bone Calcium is the most abundant mineral in the human body The average adult body contains in total approximately 1 kg, 99% in the skeleton in the form of calcium phosphate salts. Calcium From the IOM: 1- People of ages 9–18 years are not to exceed 3 g/day combined intake. 2- For ages 19–50, not to exceed 2.5 g/day. 3- For ages 51 and older, not to exceed 2 g/day. EFSA set the UL for all adults at 2.5 g/day, but decided the information for children and adolescents was not sufficient to determine ULs The body regulates calcium homeostasis with two pathways; one is signaled to turn on when blood calcium levels drop below normal and one is the pathway that is signaled to turn on when blood calcium levels are elevated The amount of calcium in blood (more specifically, in blood plasma) can be measured as total calcium, which includes both protein-bound & free calcium. In contrast, ionized calcium is a measure of free calcium. An abnormally high level of calcium in plasma is termed hypercalcemia and an abnormally low level is termed hypocalcemia, with "abnormal" generally referring to levels outside the reference range. Homeostasis Osteoporosis Osteoporosis World War II, also known as the Second World War, was a global war that lasted Osteoporosis is a disease in which bone weakening increases the risk of a broken bone. It is the most common reason for a broken bone among the elderly. Osteoporosis is defined as a bone density of 2.5 standard deviations below that of a young adult which measured by dual-energy X-ray absorptiometry (DEXA) Osteoporosis Osteoporosis Osteoporosis may be due to lower-than-normal maximum bone mass & greater-than-normal bone loss. Bone loss increases after menopause due to lower levels of estrogen. Osteoporosis may

Medicinal Uses of Fennel Overview Information Fennel Is Widely Employed As A Carminative , To Treat Flatulence By Encouraging The Expulsion Of Intestinal Gas. On Account Of Its Carminative Properties, Fennel Is Chiefly Used Medicinally With Purgatives To Allay Their Side Effects Medicinal Uses of Fennel Overview Information Ginger 7 Researchers Think The Active Components Of The Ginger Root Are Volatile Oils And Pungent Phenol Compounds (Such As Gingerols And Shogaols). It Also Contains Galanolactone Which Is A Competitive Antagonist On 5-Hydroxytryptamine Receptor “Mediator Of Nausea And Vomiting”. Medicinal Uses Of Ginger Overview Information Nausea & Vomiting in Pregnancy Human studies suggest that 1 gram daily of ginger may reduce nausea and vomiting in pregnant women when used for short periods (no longer than 4 days). Several studies have found that ginger is better than placebo in relieving morning sickness. Medicinal Uses Of Ginger Overview Information Nausea and vomiting after surgery Research is mixed as to whether ginger can help reduce nausea and vomiting following surgery. 2 studies found that 1g of ginger root before surgery reduced nausea as well as a leading medication. In one of these studies, women who took ginger also needed fewer medications for nausea after surgery. Medicinal Uses Of Ginger Overview Information

Your doctor will recommend that you physically and mentally rest to recover from a concussion. are there different types or degrees of a concussion? Past Evaluations: Finger Method Walk a straight line Reading Number line reaction time Current Evaluations: Balance testing Physical examination concentration months of the year in reverse, digits backwards memory (recall of 3 words at 5 minutes) examination of the cranial nerves neurological examination-deficits may persist for up to 10 days after concussion cervical spine assessed for tenderness, spasm and range of motion SCAT2 Well known athletes that have suffered from concussions Short Term concussive effects (lasting a few hours to a few weeks): Physical: concussion signs headaches vertigo change in sleep patterns lightheadedness tinnitus (Ringing in ears) coma blurred vision/seeing stars being dazed nausea/vomiting difficulty with mobility or coordination loss of consciousness Short and long term effects a concussion is when the brain shifts or shakes suddenly inside the skull and can knock against the skulls bony surface. A hard hit to the body can cause whiplash in the neck making the brain brush against bony protuberances inside the skull. Hard hits can also result in a rotational injury in which the brain twists, potentially causing shearing of the brain nerve fibers.

And if you were able to cooperate you were able to play again Then vs. now Treatment now Simple Concussion: Results in persistent symptoms and can effect the brain function. Grade 1: Is a mild concussion it doesn't effect much on the brain and will wear off in a matter of days. Grade 2 (post traumatic amnesia: Does not result in loss of consciousnesses but symptoms last longer than 20 min. Grade 3: Is the most severe concussion of them all. You can loose consciousness and can often cant remember what happen before the injury.
