Anatomy Notes
Concise 10–15 Pages of Basic Human Anatomy with Practice Questions
,Introduction to Human Anatomy
• Definition: Anatomy is the study of the structure of the human body.
• Branches: Gross Anatomy, Microscopic Anatomy, Developmental Anatomy.
• Levels of organization: Cells → Tissues → Organs → Systems → Organism.
Skeletal System
• Functions: Support, protection, movement, mineral storage, blood cell formation.
• Adult human skeleton has 206 bones.
• Divisions: Axial (skull, vertebral column, thorax) and Appendicular (limbs, girdles).
Muscular System
• Types of muscles: Skeletal (voluntary), Cardiac (involuntary, heart), Smooth (involuntary,
organs).
• Functions: Movement, posture maintenance, heat production.
• Tendons connect muscle to bone.
Circulatory System
• Heart: 4 chambers (2 atria, 2 ventricles).
• Blood vessels: Arteries (away from heart), Veins (toward heart), Capillaries (exchange).
• Functions: Transport nutrients, oxygen, hormones, and waste.
Respiratory System
• Organs: Nose, pharynx, larynx, trachea, bronchi, lungs.
• Gas exchange occurs in alveoli.
• Functions: Provides oxygen, removes carbon dioxide.
Digestive System
• Organs: Mouth, esophagus, stomach, intestines, liver, pancreas.
• Functions: Ingestion, digestion, absorption, elimination.
• Small intestine is main site for nutrient absorption.
Nervous System
• Divisions: Central Nervous System (CNS), Peripheral Nervous System (PNS).
• Neuron is the functional unit.
• Brain lobes: Frontal, Parietal, Temporal, Occipital.
, Reproductive System
• Male: Testes, vas deferens, penis, glands.
• Female: Ovaries, fallopian tubes, uterus, vagina.
• Function: Production of gametes and hormones, reproduction.
