Discussion about the Parts

  • Jaw: The jaw of the human being is one of the most important parts of the body. It helps us chew food, speak, and keep our teeth healthy. The lower jaw, or mandible, is the bone that connects the tongue to the teeth. The upper jaw, or maxilla, is the bone that supports the nose and cheeks.
  • Jugular Foramen: The jugular foramen is a small bony opening in the skull that allows the jugular vein and other nerves to pass from the brain to the neck. You can find it at the base of the brain, just behind the ears. Because of its location, it’s sometimes referred to as the “back door” to the brain.
  • Jugular Veins: The jugular vein is a large vein that carries de-oxygenated blood from the head and neck region to the heart. It is one of the main veins in the body and can be easily seen and felt when the neck swells up.
  • Jankl: Jankl is the Yiddish word for liver. In English, we sometimes call the liver the “seat of emotions.” This is because the liver is responsible for filtering toxins out of the blood and producing bile, which helps digest food. The liver also helps to regulate glucose levels in the blood and has cholesterol. The liver is one of the essential organs in the human body, and it plays a vital role in our overall health and wellbeing. Unfortunately, many people don’t realize how strong their liver is until it’s too late. To keep your liver healthy, it’s important to eat a healthy diet and avoid toxins. 
  • Jari: It’s a pretty vital organ, and without it, we wouldn’t be able to digest food properly. The Jari consists of smooth muscle tissue, and it contracts (or squeezes) to help push food through the digestive system. It can also acquire independently from the rest of the gastrointestinal system, allowing us to control how quickly food moves through our bodies.
  • Jawbone: Jawbone is the bones of the mouth that hinge the mandible (lower jaw). The human jawbone consists of the maxilla (upper jaw), which houses the upper teeth, and the mandible contains the lower teeth. Jawbones are some of the most robust bones in the human body and are necessary for eating and speaking.
  • Jiggly Arm: Jiggly arm is the name given to a condition where the arms sag and jiggle due to excess skin or fat. Due to the higher body fat composition in women, it is more common in them. When obese individuals lose weight, they often have loose skin that hangs from their limbs, which gives the appearance of “jiggly arms.”
  • Joint: When two or more bones meet, they’re held together by muscles, ligaments, and tendons. The human body has many joints, including the knees, hips, elbows, and shoulders.
  • Joints: There are three main joints in the human body: fixed, movable, and pivot. Fixed joints are also called immovable or fused joints. A fixed joint is a junction between the ribs and the sternum (breastbone). Movable joints refer to articulating or freely moving joints. An example of a movable joint is the knee. Pivot joints allow for rotation around a central point. For instance, the elbow is an example of a pivot joint.
  • Jopo: Jopo is a body part that is often overlooked but plays a vital role in our bodies. The Jopo is located just below the navel and helps to support the digestive system. This small yet essential organ helps break down food and absorb nutrients. It also eliminates waste from the body and prevents toxins from building up. Without the Jopo, we would not be able to digest our food or eliminate waste products effectively correctly.
  • Joues: Joues is the plural form of the French word for “cheek.” In English, we typically use this word to refer to the fleshy part of the face that sits below the eyes and extends to the sides of the mouth. The cheeks are an important facial feature and convey a wide range of expressions. For example, when someone blushes, it’s usually in response to embarrassment or shame – their cheeks give away their inner emotions.
  • Jugular: The jugular vein is a large vein on the right side of the neck that carries blood from the head and brain to the heart. It’s in the front of the neck, just below where the skull meets the upper body.
  • Jejunum: The jejunum is the section of the small intestine in the middle that is responsible for digesting food. It’s about 2-3 feet long and situated between the stomach and the ileum (the final section of the small intestine). Almost all nutrients we ingest through our food pass through the jejunum. This occurs because there are many more villi in the jejunum than in the other sections of the small intestine.
  • Juxtaglomerular cell: The juxtaglomerular cell is a type of cell in the kidney that is responsible for secreting renin. Renin is an essential hormone in the body that helps regulate blood pressure. Juxtaglomerular cells reside in the juxtaglomerular apparatus, a small group of cells located near the glomeruli (the kidney’s filtration units). These cells are essential for maintaining normal blood pressure and fluid balance.
