Study Notes
Learning Objectives
- Define anatomy and physiology.
- Identify locations and functions of organ systems and major organs in the human body.
- Understand important life processes in the human body.
- Explain the significance of homeostasis and its relationship to disorders.
- Describe the human body using anatomical position and terminology.
Basic Anatomical Terminology
- Body Positions: Anatomical position is a standardized method for anatomical reference where the body stands erect, facing forward, arms at sides, palms forward, and feet flat.
- Supine: Lying face-up.
- Prone: Lying face-down.
Regional Names
- Specific names assigned to body regions for reference.
Directional Terms
- Essential for locating body parts relative to each other:
- Superior: Toward the head (e.g., heart is superior to liver).
- Inferior: Away from the head (e.g., stomach is inferior to lungs).
- Anterior/Ventral: Front of the body (e.g., sternum is anterior to the heart).
- Posterior/Dorsal: Back of the body (e.g., esophagus is posterior to trachea).
- Medial: Nearer to the midline (e.g., ulna is medial to radius).
- Lateral: Farther from the midline (e.g., lungs are lateral to heart).
- Intermediate: Between two structures (e.g., transverse colon is intermediate to ascending and descending colons).
- Ipsilateral: On the same side (e.g., gallbladder and ascending colon).
- Contralateral: Opposite sides (e.g., ascending and descending colons).
- Proximal: Nearer to trunk attachment (e.g., humerus is proximal to radius).
- Distal: Farther from trunk attachment (e.g., phalanges are distal to carpals).
- Superficial: On the body surface (e.g., ribs are superficial to lungs).
- Deep: Away from the body surface (e.g., ribs are deep to skin).
Serous Membranes
- Thin, double-layered membranes covering viscera in thoracic and abdominal cavities.
- Parietal layer: Lines cavity walls.
- Visceral layer: Covers viscera.
- Serous fluid: Reduces friction during organ movement.
Types of Serous Membranes
- Pleura: Surrounds lungs (visceral pleura on lungs, parietal pleura lining chest wall).
- Pericardium: Covers the heart (visceral pericardium on heart, parietal pericardium lining chest).
- Peritoneum: Encloses abdominal organs (visceral peritoneum covers organs, parietal peritoneum lines abdominal wall).
- Retroperitoneal organs: Include kidneys, adrenal glands, pancreas, and parts of abdominal aorta (located behind peritoneum).
Abdominopelvic Regions and Quadrants
- Divided to describe organ locations effectively.
Medical Imaging Procedures
- CT Scan (Computed Tomography): Uses X-rays at multiple angles to create detailed images of soft tissues and organs, useful for diagnosing tumors and other conditions.
- Ultrasound Scanning: Employs high-frequency sound waves to visualize organs; commonly used in pregnancy.
- CCTA Scan (Coronary CT Angiography): Injects contrast medium to assess coronary artery blockages; offers detailed images of the heart's structure.
- PET Scan (Positron Emission Tomography): Visualizes metabolic activity by detecting gamma rays from injected substances; useful for studying brain or heart physiology.
- Endoscopy: Visual examination of internal organs using an endoscope for procedures like colonoscopy and laparoscopy.
- Radionuclide Scanning: Involves injecting radioactive substances to image tissues; areas of high activity show intense color on images, used for various organ studies (e.g., SPECT scanning).
