Study Notes
Overview of Human Anatomy
- Human anatomy is the study of the structure of the human body, including the physical form and position of its parts.
- It encompasses all levels of organization from the cellular to the systemic.
- The study broadly covers gross anatomy (visible structures), microscopic anatomy (structures viewed with microscopes), and developmental anatomy (changes in structure over time).
Anatomical Terminology
- Standardized anatomical terminology is crucial for clear and precise communication among healthcare professionals.
- Precise directional terms (e.g., superior, inferior, anterior, posterior) facilitate description of body locations and relationships.
- Regional terms (e.g., cephalic, cervical) describe specific areas of the body.
- Planes of section (e.g., sagittal, transverse, coronal) help visualize internal structures.
Body Cavities
- Body cavities are spaces enclosed by membranes that contain and protect internal organs.
- The dorsal cavity houses the brain and spinal cord.
- The ventral cavity is larger and houses the major organs of the body, like the heart, lungs, and stomach, further divided into thoracic and abdominal cavities.
- The peritoneal cavity is a specific cavity within the abdominal cavity.
Skeletal System
- The skeletal system provides support, protection, and leverage for movement.
- Bones are composed of living cells embedded in a hard matrix of calcium salts and collagen fibers.
- Bones are classified by shape (long, short, flat, irregular, sesamoid).
- Joints connect bones and allow for movement.
Muscular System
- The muscular system enables movement, maintains posture, and generates heat.
- Muscles are composed of specialized cells called muscle fibers.
- Muscles are categorized based on structure and function: voluntary (skeletal) and involuntary (smooth, cardiac).
Nervous System
- The nervous system coordinates body functions through electrochemical signals.
- It consists of the central nervous system (brain and spinal cord) and the peripheral nervous system (nerves).
- Neurons are specialized cells that transmit signals throughout the body. They vary in structure but all have a cell body, dendrites, and an axon.
Cardiovascular System
- The cardiovascular system circulates blood throughout the body to deliver oxygen, nutrients, and remove waste products.
- The heart pumps blood through the blood vessels (arteries, veins, and capillaries).
- Blood is a connective tissue containing red blood cells to carry oxygen, white blood cells to combat infection, and platelets for blood clotting.
Respiratory System
- The respiratory system facilitates gas exchange between the environment and the body.
- The lungs are the primary organs, enabling the absorption of oxygen and release of carbon dioxide. They contain various alveoli used in that process.
Digestive System
- The digestive system processes food, absorbs nutrients, and eliminates waste.
- Various organs participate including the mouth, esophagus, stomach, intestines, and accessory organs such as the liver and pancreas.
Urinary System
- The urinary system filters blood, eliminates metabolic waste, and regulates water balance.
- The kidneys are the primary filtering organs, producing urine which waste is eliminated via the urinary bladder through the urethra.
Endocrine System
- The endocrine system regulates body functions through hormones, which are chemical messengers.
- It consists of glands that secrete hormones into the bloodstream.
- Essential glands include the thyroid, pituitary, adrenal, and gonads.
Lymphatic and Immune System
- The lymphatic and immune systems defend against disease and infection.
- Includes the lymph nodes, lymphatic vessels, and various cells of the immune system.
Integumentary System
- The integumentary system covers and protects the body from the outside environment.
- Includes the skin, hair follicles, sweat glands, and nails; the skin itself providing sensory input and protection.
Reproductive System
- The reproductive system enables procreation.
- The male and female reproductive systems have separate structures, producing gametes (sperm and eggs) that fuse during fertilization.
Developmental Anatomy
- Developmental anatomy studies the changes in the human body over its lifespan.
- Developmental stages, from conception to adulthood, involves significant changes in structure and functionality, all governed by specific genetic programs.
