Relaxin

Relaxin is a hormone in our bodies that helps us relax, especially during pregnancy. It's like a natural "chill" hormone. 

During pregnancy, relaxin is made by the ovaries and later by the placenta. It has a few important jobs:

1. **Loosening Muscles and Joints:** Relaxin helps to relax the muscles of the uterus, which is important for a smooth pregnancy and childbirth. It also loosens the ligaments in the pelvis to make it easier for the baby to pass through during birth.

2. **Softening the Cervix:** It makes the cervix (the opening to the womb) softer and more flexible, allowing it to stretch during labor.

3. **Prepares for Breastfeeding:** Relaxin can also prepare the body for breastfeeding by affecting the milk-producing glands.

So, in simple terms, relaxin is like your body's natural relaxer, helping to make pregnancy and childbirth a bit easier.

Structure of myosin & actin filaments.

Image
i. Myosin filament: a. Each myosin filament is a polymerized protein. Many meromyosins (monomeric proteins) i constitute one thick filament. b. Myosin molecule consists of two heavy chains (heavy meromyosin / HMM) coiled around each other forming a double helix. One end of each of these chains is projected outwardly is known as cross bridge . This end folds to form a globular protein mass called myosin head . c. Two light chains are associated with each head forming 4 light chains/light meromyosin / LMM. d. Myosin head has a special ATPase activity . It can split ATP to produce energy. e. Myosin contributes 55% of muscle proteins. f. In sarcomere, myosin tails are arranged to point towards the centre of the sarcomere and the heads point to the sides of the myofilament band. ii. Actin filament : It is a complex type of contractile protein. It is made up of three components: a. F actin : It forms the backbone of actin filament. F actin is made up of two helica

Table of content:  1. Plants 2. Animals 3. Humans 4.  Gods Plant Plants   are the   eukaryotes   that form the   kingdom   Plantae ; they are predominantly   photosynthetic . This means that they obtain their energy from   sunlight , using   chloroplasts   derived from   endosymbiosis   with   cyanobacteria   to produce   sugars   from   carbon dioxide   and water, using the green pigment   chlorophyll . Exceptions are   parasitic plants   that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Animal Historically, as in  Aristotle's biology , the plant kingdom encompassed all living things that were not  animals , and included  algae  and  fungi . Definitions have narrowed since then; current definitions exclude the fungi and some of the algae. By the definition used in this article, plants form the  clade   Viridiplantae  (green plants), which consists of the  green algae  and the  embryophytes  or land plants ( hornworts ,
