Study Notes

Anatomy

Anatomy is the study of the body's structures, including size and shape, and how they relate to function.
Bones, for instance, are made of hard, mineralized material, providing support and strength.
Understanding the connection between structure and function facilitates learning anatomy.
Studying anatomy can be approached in various ways:
- Developmental anatomy tracks bodily changes from conception to adulthood. Embryology specifically focuses on development from conception to 8 weeks.
- Microscopic anatomy examines minute structures (cells and tissues) requiring a microscope.
- Gross anatomy studies visible structures without a microscope, either by body systems (e.g., skeletal) or regions (e.g., head).
- Surface anatomy observes external features to understand internal structures (e.g., chest shape to locate the heart).
- Anatomical imaging uses tools like X-rays, MRIs, and ultrasounds to visualize internal structures non-invasively.
Each person's anatomy is unique. Anatomical anomalies are variations, ranging from minor differences to serious conditions.

Physiology

Physiology studies how the body functions, responding to changes and maintaining balance.
Physiological processes can be considered at different levels, including:
- Cell physiology examines cell processes.
- Systemic physiology analyzes how organ systems work.
- Examples include Neurophysiology (nervous system) and Cardiovascular Physiology (heart and blood vessels).
Anatomy and physiology are interconnected; structure and function are closely correlated.
Pathology explores diseases, their causes, and effects on structure and function.
Exercise physiology studies how physical activity changes the body.

Imaging Techniques

X-rays use shortwave electromagnetic radiation to visualize internal structures. Dense structures appear white. Clinical uses include broken bones and dental issues. A limitation is its 2D nature.
Ultrasound uses high-frequency sound waves, reflected signals being used to create an image (sonogram). Clinical applications include fetal health assessments and internal organ evaluations.
Computed Tomography (CT) utilizes a rotating X-ray tube to generate cross-sectional images (slices), reconstructible into 3D views. Clinical applications are detailed internal structure imaging, such as the brain or chest.
Digital Subtraction Angiography (DSA) uses a baseline X-ray image, then a second image following dye injection. The baseline is subtracted to highlight blood vessels, enabling visualization of blood vessels (angioplasty).
MRI uses magnetic fields and radio waves to create highly detailed images. Clinical applications target tissue abnormalities, aiding cancer and soft tissue diagnosis.
PET uses radioactively tagged glucose to track metabolic activity. Gamma rays highlight metabolically active areas. Clinical use includes studying brain activity and detecting cancerous tissues based on metabolism.

Levels of Organization

The human body is organized hierarchically, starting with chemical level (atoms bonding to form molecules).
These molecules form organelles within cells, the fundamental unit of life.
Similar cells with similar function aggregate to form tissues.
Multiple tissues combine to form organs, structures performing specific tasks.
Multiple organs working together create organ systems.
All organ systems function together to form the organism (human body).

Organ Systems

The human body has various organ systems. The note references 12 organ systems, detailing their basic components and functions, for example, the integumentary system (skin, hair, nails), skeletal system (bones, cartilage), muscular system (muscles), lymphatic system (lymph nodes, vessels, spleen), respiratory system (lungs, airways), digestive system (stomach, intestines, liver, pancreas), nervous system (brain, spinal cord, nerves), endocrine system (glands like thyroid, adrenal), cardiovascular system (heart, blood vessels), urinary system (kidneys, bladder, urethra), and reproductive system (reproductive organs).
