Study Notes
Regional Anatomy
- Body organized by areas: head, neck, trunk, abdomen, etc.
- Systemic anatomy example: digestive system organs include oral cavity, esophagus, stomach, small intestine, large intestine, and rectum.
- Digestive system function: breaks down food into absorbable nutrients, eliminates indigestible materials as feces.
Microscopic Anatomy
- Stomach structure includes gastric pits and gastric glands.
- Main cell types in stomach: mucous neck cells, parietal cells, chief cells.
Structural and Functional Organization
- Organ System Level: Group of organs functioning as a unit with common functions (e.g. digestive system).
- Organism Level: Refers to a whole being, ranging from single cells to complex organisms (e.g. human).
Levels of Biological Organization
- Chemical Level: Atoms combine to form molecules.
- Cellular Level: Molecules combine to form cells, such as smooth muscle cells.
- Tissue Level: Tissues are composed of similar cell types (e.g., smooth muscle tissue).
Organ Systems Overview
-
Cardiovascular System: Includes heart and blood vessels; functions to pump and transport blood carrying oxygen, carbon dioxide, nutrients, hormones, and waste. Contains protective white blood cells.
-
Lymphatic System: Comprises lymphatic vessels and nodes; works alongside the cardiovascular system to return leaked fluids, cleanse blood, and support immunity.
-
Respiratory System: Encompasses nasal passages, trachea, bronchi, and lungs; supplies oxygen to the body and removes carbon dioxide through gas exchange in the lungs' air sacs.
Body Planes and Sections
- Divides body/organ into sections:
- Sagittal: Left and right parts.
- Median/Midsagittal: Equal left and right parts.
- Frontal/Coronal: Anterior and posterior parts.
- Transverse/Cross: Superior and inferior parts.
Body Cavities
- Dorsal Cavity: Contains Cranial cavity (housing the brain) and Spinal cavity (housing the spinal cord).
- Ventral Cavity: Divided by the diaphragm into the thoracic cavity (houses heart and lungs) and the abdominopelvic cavity (contains digestive and reproductive organs).
Abdominopelvic Cavity
- Further divided into quadrants: Right Upper Quadrant (RUQ), Left Upper Quadrant (LUQ), Right Lower Quadrant (RLQ), Left Lower Quadrant (LLQ).
- Divided into nine regions: Right hypochondriac, Epigastric, Left hypochondriac, Right lumbar, Umbilical, Left lumbar, Right iliac (inguinal), Hypogastric (pubic), Left iliac (inguinal).
Additional Body Cavities
- Include oral and digestive cavities, nasal cavity, orbital cavities, and middle ear cavities.
