ការប្រែប្រួលសន្លាក់នៅពេលមានផ្ទៃពោះ-Joint Changes During Pregnancy

During pregnancy, contains hormones such as estrogen, progesterone, and relaxin act on the connective tissue of joints, particularly the symphysis pubis. making them more stretchable and allowing the joints to loosen. This change allows the pelvic opening to enlarge at the time of delivery. After delivery, the connective tissue of the symphysis pubis returns to its original condition. However, the enlarged pelvic opening may not return completely to its original size, and the woman may have slightly wider hips after the birth of the child.
The same hormones may act on the connective tissue of other joints in the body. such as the arches of the feet. causing them to relax, which may result in fallen arches. They may also act on some of a baby's joints, such as the hip, causing them to become more mobile than normal. Increased mobility of the hip can result in congenital (appearing at birth) partial or complete dislocation of the hip. Congenital hip dislocation occurs approximately once in every 1000 births. Fortunately, if detected early the condition can be corrected using a specialized harness or traction to realign the joint.

Chemical Reactions and Energy

Synthesis Reactions A chemical reaction occurs when atoms, ions, molecules, or compounds interact either to form or to break chemical bonds. Reactants are substances that enter into a chemical reaction, whereas the substances that result from the chemical reaction are called products. A synthesis reaction is when two or more reactants chemically combine to form a new and larger product. The synthesis reactions occurring in the body are collectively referred to as anabolism. These reactions produce the molecules characteristic of life, such as ATP, proteins, carbohydrates, lipids, and nucleic acids. Some conditions of the body such as growth, maintenance, and repair could not take place without anabolic reactions. Synthesis reactions in which water is a product are called dehydration (water out) reactions. Decomposition Reactions A decomposition reaction is the reverse of a synthesis reaction—a larger reactant is chemically broken down into two or more smaller products. T...

BIOLOGICAL MACROMOLECULES

Image
Bio-molecules are a subset of organic molecules. Organic molecules are defined as molecules or compounds that contain both carbon and hydrogen. Most organic molecules are a component of living organisms or have been produced from them. All other types of molecules are inorganic molecules including water, salts (e.g., sodium chloride), acids (e.g., carbonic acid), and bases (e.g., sodium hydroxide). The four major classes of organic biological macro-molecules (bio-molecules) are lipids, carbohydrates, nucleic acids, and proteins.
