▎Introduction to Anatomy
▎Definition of Anatomy
Anatomy is the branch of biology that deals with the study of the structure and organization of living
organisms. It encompasses the examination of body parts, their relationships, and how they function
together to maintain life. Anatomy can be divided into two main categories: macroscopic (gross)
anatomy and microscopic anatomy.
▎1. Macroscopic Anatomy
Macroscopic anatomy, also known as gross anatomy, involves the study of structures that can be seen
with the naked eye. This includes the examination of organs, tissues, and systems within an organism.
Macroscopic anatomy can further be classified into:
• Regional Anatomy: Focuses on specific regions of the body, such as the head, neck, thorax, abdomen,
and limbs. It studies all the structures in a particular area.
• Systemic Anatomy: Examines specific organ systems (e.g., muscular, skeletal, cardiovascular)
throughout the body, regardless of the region.
▎2. Microscopic Anatomy
Microscopic anatomy involves the study of structures that cannot be seen without magnification. This
includes:
• Histology: The study of tissues. Tissues are groups of cells that work together to perform specific
functions. There are four primary types of tissues in the human body:
– Epithelial Tissue: Covers body surfaces and lines cavities.
