The zygomatics major is a muscle of the human body. It is a muscle of facial expression which draws the angle of the mouth superiorly and posteriorly to allow one to smile. Like all muscles of facial expression, the zygomatic major is innervated by the facial nerve. The Zygomatics extends from each zygomatic arch (cheekbone) to the corners of the mouth. It raises the corners of the mouth when a person smiles. Usually a single unit, dimples are caused by variations in form. It is thought that dimples are caused by bifid zygomaticus major muscle. Does it take more muscles to smile or to frown? Some claim that it takes 43 muscles to frown and 17 to smile while others says it takes 26 to smile and 62 to frown. And some naysayers claim it is the opposite. Dont get into the rigmarole of the number of muscles. SMILE, SMILE, SMILE.......Smile is the best exercise. It increases your face value.

The yolk sac is situated on the ventral aspect of the embryo. It is filled with fluid, the vitelline fluid, which possibly may be utilized for the nourishment of the embryo during the earlier stages of its existence. Blood is conveyed to the wall of the sac by the primitive aortae , and after circulating through a wide-meshed capillary plexus, is returned by the vitelline veins to the tubular heart of the embryo. This constitutes the vitelline circulation, and by means of its nutritive material is absorbed from the yolk-sac and conveyed to the embryo. After the end of the fourth week the yolk-sac presents the appearance of a small pear-shaped vesicle (umbilical vesicle) opening into the digestive tube by a long narrow tube, the vitelline duct. Function The yolk-sac is also responsible for the initial circulation and is in charge of delivering nutrients, via a primitive aorta, to the developing embryo. The yolk-sac provides nutrition to the developing embryo until the placenta takes over. How does the yolk-sac disappear? As the pregnancy advances, the yolk-sac progressively increases from the 5th to end of the 10th gestational week, following which the yolk sac gradually disappears and is often sonographically undetectable after 14-20 weeks. Readers, did you know about yolk-sac earlier? I am participating in the A to Z Challenge.
What is xiphoid Process? The xiphoid process is the smallest region of the sternum or breastbone. It is made up of cartilage at birth but develops into bone in adulthood. It's located where the lower ribs attach to the breastbone. The tip of the xiphoid process resembles a sword. although xiphoid process is small, it serves as an attachment point for organs and large muscles that make the floor of the diaphragm. Symptoms of xiphoid process pain Pain caused by the xiphoid process is called xiphoidalgia. Xiphoid process pain occurs for varying reasons. Pain is typically felt in the lower part of the sternum. The sternum is the bone that makes up the middle front of your ribcage. Pain is described as pressure or tightness. Causes of pain in xiphoid process Pain can occur after an accident tht causes chest trauma. This damages the structure of the xiphoid process, causing it to bend or break off. Damage can also occur from incorrect CPR (Cardiopulmonary resuscitation ) A broken Xiphoid process increases inflammation. Xiphoid process pain can be felt with acid reflux.

The waist is the part of the abdomen between the rib cage and hips. On people with slim bodies, the waist is the narrowest part of the torso. The waistline refers to the horizontal line where the waist is narrowest. Waistline differs from person to person. To locate the natural waistline, one need simply stand upright and then tilt over to the side keeping the legs and hips straight. Where the torso creases , that is the natural waistline. The waist is usually measured just above the belly button. In case the waist is convex rather than concave, such as in the case of pregnancy and obesity. the waist may be measured at a vertical level 1 inch above the navel. The size of a person's waist or waist circumference, indicates abdominal activity. Excess abdominal fat is a risk factor for developing heart disease and other obesity related diseases.
YouTube video Practice these yoga poses under proper guidance or consult your doctor. What causes waist pain in females? The most common sources of pain in the lower back are overuse injuries to body muscles, ligaments and/or joints, injuries like muscle sprains and strains commonly occur due to sudden movement or improper lifting techniques.

Waist and Waste are homophones. They sound the same but they have different meanings and spellings. Readers , do you do yogasanas for reducing abdominal fat?

The vertebral column also known as the backbone or spine is part of the axial skeleton.The vertebral column houses the spinal canal, a cavity that encloses and protects the spinal cord. In human vertebral column there are normally 33 vertebrae, the upper 24 are articulating and separated from each other by Inter-vertebral discus, and the lower 9 are fused in adults.The articulating vertebrae are named according to their region of the spine. There are seven cervical vertebrae , 12 thoracic vertebrae and 5 lumbar vertebrae. Cervical spine : 7 vertebrae ( C1-C7) Thoracic spine : 12 vertebrae ( T1-T12) Lumbar spine : 5 vertebrae (L1-L5) Sacrum : 5 (fused) vertebrae (S1-S5) Coccyx : 4 (3-5)(fused) vertebrae (Tailbone) A typical vertebra consists of 2 parts : the vertebral body and the vertebral arch. The vertebral arch is posterior, i.e. it faces the back of the person. Shape The upper cervical spine has a curve, convex forward, that begins at the axis and ends at the middle of the second thoracic vertebra. This inward curve is known as a lordotic curve. Function The vertebral column surrounds the spinal cord which travels within the spinal canal, formed from a central hole within each vertebra. The spinal cord is part of the central nervous system that supplies nerves and receives information from the peripheral nervous system within the body. Diseases Spina bifida is a congenital disorder in which there is a defective closure of the vertebral arch. sometimes the spinal meninges and also the spinal cord can protrude through this, and this is called Spine bifida cystica. Where the condition does not involve this protrusion it is known as Spina bifida occulta. Sometimes all of the vertebral arches may remain incomplete. Spinal disc herniation, more commonly called a 'slipped disc'is the result of a tear in the outer ring of the intervertebral disc , which lets some of the soft gel-like material, the nucleus pulposus, bulge out in the hernia. Spinal stenosis is a narrowing of the spinal canal which can occur in any region of the spine though less commonly in the thoracic region. The stenosis can constrict the spinal canal giving rise to a neurological deficit. How to strengthen the spine?
