Which are the special proteins in muscles that contract and relax to cause movement?

 

We know that, there are four types of tissue in human body. They are 

1.Muscular
2.Connective
3.Epithelial
4.Nervous

Among these Connective Tissue are most abundant in our body. 

CONNECTIVE TISSUE

Connective tissue is found in between other tissues everywhere in the body, including the nervous system. It develops from the mesoderm.

Functions:

1) Wraps around and cushions and protects organs
2) Stores nutrients
3) Internal support for organs
4) As tendon and ligaments protects joints and attached muscles to bone and each other
5) Runs through organ capsules and in deep layers of skin giving strength

The 3 Elements of Connective Tissue are

1) Ground substance – gel around cells and fibers
2) Fibers – provide strength, elasticity and support
3) Cells

Tooth Enamel is the hardest and most highly mineralized substance in the human body. It is a tissue and not a bone. This tissue has high mineral content which makes it hardest substance.

Femur and Temporal bone of the skull are the hardest bones of the human body.

The branch of biology that studies the different structures and functions of the cell is called Cell Biology or Cytology.

 
Cell biology (formerly called Cytology), is a Greek word: kytos, "vessel" is a branch of biology that studies the different structures and functions of the cell and focuses mainly on the idea of the cell as the basic unit of life.

The cell (from Latin cella, meaning "small room") is the basic

• Structural,

• Functional (and) 

• Biological unit of all known living organisms. 

A cell is the smallest unit of life that can replicate independently, and cells are often called the "building blocks of life".

Cell Biology deals with :

• Life cycle 

• Structure and organisation of cell organelles and their physiological properties. 

• Metabolic processes 

• Interactions with their environment 

• Signalling pathways.

Chloroquine is a medication used to prevent and to treat malaria.

Blood Platelets are the components of the blood that are helpful in clotting of the blood.
