The study of the structures that make up the human body, including the brain, is known as anatomy. Anatomy focuses on understanding the shapes, sizes, and locations of different body parts and how they relate to each other. It is an important field in medicine and biology for diagnosing and treating various health conditions.
There are several thousand of them. You need to be more specific

Anatomical structures refer to the parts and components that make up an organism's body, such as organs, tissues, and bones. Understanding these structures helps researchers study the function and organization of living organisms.

The rigid structures that make up the skeleton are bones. The human skeleton is composed of 206 bones that provide support, protection, and leverage for movement. These bones are connected by joints, ligaments, and tendons to form a complete framework for the body.
The tissues that make up the body are collectively known as the body's tissue system. This includes epithelial, connective, muscular, and nervous tissues, which work together to form organs and structures within the body.
Hyphae
Thread like structures in fungi are called hyphae .
The order of structures of the human body from smallest to largest are:cellgroups of specialized cells make a certain type of tissue, for example, muscle tissuea group of alike tissues make up an organa group of organs that all have a similar function make up an organ systemall of the organ systems make up the organism, e.g. the human body
The smallest part working in your body is typically considered to be atoms, which make up molecules, cells, tissues, organs, and ultimately, your entire body. Atoms are the building blocks of all matter, including the complex biological structures that make up living organisms like humans.
