Study Notes
Anatomical Language & Orientation Terms
- Anatomical terminology is primarily derived from Greek and Latin.
- Over 7000 terms exist in human anatomy that require memorization for comprehension.
- Standard anatomical position involves the body standing upright, facing forward, arms at the sides, with palms facing forward.
Levels of Organization in Living Things
- Cells are the smallest units of life.
- Tissues consist of similar cells with a shared structure and function.
- Organs are made up of at least two tissue types that serve specific roles.
- Organ systems are groups of organs collaborating to perform a collective function.
- The organism level encompasses all structural levels working together to sustain life.
Body Systems & Associated Organs
- Integumentary: Skin, hair, fingernails
- Skeletal: Bones, cartilage, joints
- Muscular: Skeletal muscles
- Nervous: Brain, spinal cord, nerves, tonsils, testes
- Endocrine: Ovaries, pituitary gland, pineal gland, pancreas
- Cardiovascular: Heart, blood vessels
- Lymphatic: Lymph nodes, spleen
- Respiratory: Lungs, larynx, pharynx, trachea
- Digestive: Stomach, small and large intestines, pancreas
- Urinary: Bladder, ureters, kidneys, urethra
- Reproductive: Ovaries, uterus, testes
Anatomical Position & Body Regions
- Axial regions refer to the central part of the body, including the head and trunk.
- Appendicular regions comprise limbs hanging from the body.
- Thorax is defined as a specific point located laterally relative to the umbilicus.
Abdominal Regions
- Nine abdominal regions are defined for systematic identification:
- Right Hypochondrium: Liver, gallbladder, right kidney, parts of intestines.
- Epigastrium: Liver, stomach, pancreas, duodenum, spleen, adrenals.
- Left Hypochondrium: Spleen, kidneys, pancreas, portions of intestines.
- Right Lumbar: Ascending colon, small intestine, right kidney.
- Umbilical: Duodenum, small intestine, transverse colon.
- Left Lumbar: Descending colon, small intestine, left kidney.
- Right Inguinal: Appendix, cecum, ascending colon, small intestine.
- Hypogastric: Gallbladder, sigmoid colon, reproductive organs.
- Left Inguinal: Sigmoid colon, descending colon, small intestine.
- Subcostal and intertubercular planes are key landmarks for defining these regions.
Importance of Identifying Quadrants and Regions
- Critical for differential diagnosis of abdominal pain to localize organ issues.
Body Cavities
- Dorsal Cavity:
- Cranial cavity houses the brain.
- Spinal cavity contains the spinal cord.
- Ventral Cavity:
- Thoracic cavity is separated from the abdominal cavity by the diaphragm.
