Recent research has helped to solidify the link between the proper function of the vertebral arteries and vertigo. The researchers specifically focused on a rare condition called loop formation. It is a disorder where small loops form in the vertebral arteries, thereby restricting blood flow. When a cross-section of vertigo patients was studied, this condition seemed to be more common. What else can cause kinks in the vertebral arteries leading to reduced blood flow? Does understanding of the conditions that bring vertigo provide information into a natural way to find relief? Read on to learn more. What Can Reduce Vertebral Blood Flow and Lead to Vertigo? The upper cervical vertebrae play a major role in facilitating blood flow to the brain. Misalignment of the C1 and C2 vertebrae can result in reduced blood flow. Vertigo is not the only possible condition that may result from this scenario. Migraines are also common when these circumstances exist. This explains why it is s...

                                     Nipple The  nipple  is a raised region of tissue on the surface of the  breast  from which, in females,  milk  leaves the breast through the  lactiferous ducts  to feed an infant. The milk can flow through the nipple passively or it can be ejected by  smooth   muscle contractions  that occur along the ductal system. The nipple is surrounded by the  areola , which is often a darker color than the surrounding skin. A nipple is often called a  teat  when referring to non-humans. Nipple or teat can also be used to describe the flexible mouthpiece of a  baby bottle . In humans, nipples of both males and females can be stimulated as part of sexual arousal. In many cultures, human female nipples are  sexualized , or "regarded as sex objects and evaluated in ...

            Why do we get hiccups (उचक्या /हिचकी) ?      Hiccups are caused by involuntary contractions of your diaphragm — the muscle that separates your chest from your abdomen and plays an important role in breathing. This involuntary contraction causes your vocal cords to close very briefly, which produces the characteristic sound of a hiccup. Hiccups can be annoying but they’re usually short-lived. However, some people may experience recurrent episodes of persistent hiccups. Persistent hiccups, also known as chronic hiccups, are defined as episodes that last longer than 48 hoursTrusted Source. At its most basic, a hiccup is a reflex. It happens when a sudden contraction of your diaphragm causes the muscles of your chest and abdomen to shake. Then, the glottis, or the part of your throat where your vocal cords are located, closes. This creates the noise of air expelled from your lungs, or the “hic” sound that feels involuntary...
