Anatomy (morphology) -- study of structure of human body ... Closely related to physiology --
study of body functions
Subdisciplines (Branches) of Anatomy
• Gross anatomy - body structure seen by naked eye
• Bones, lungs, muscles
▪ Seen by dissection
o Studies of Gross Anatomy
• Systematic -- all organs studied together
▪ Studying muscular system, consider muscles of ENTIRE body.
• Regional -- structures in single body region studied as a group.
▪ Medical school
• Injuries/diseases involved in specific regions
• Microscopic anatomy (histology) -- study of tissue that can only be seen w/ a microscope
• Developmental anatomy -- structural changes occurring in body throughout life
• Embryology -- study of how body structure form/develop before birth
• Pathological -- structural change in cells, tissues, organs caused by disease
• Radiographic -- internal body structures using X-Rays
• Functional morphology -- functional properties of body structures and looks at their
efficiency of designs.
Hierarchy of Structural Organization
1. Chemical level
a. Atoms (carbon, hydrogen, oxygen etc..)
b. FORM molecules (CO2/H2O) and
i. larger macromolecules (carbohydrates[sugars[, lipids [fats], proteins, nucleic
Building blocks of structure of cellular level --> cellular organelles
2. Tissue level
Group of cells working together to perform common function.
Only 4 tissues make up all organs in human body
a. Lining tissue
2. Connective tissue
3. Muscle tissue
a. Produce movement
4. Nervous tissue
a. Internal communication by electrical impulses
3. Organ level
