Study Notes
Introduction to Anatomy
- Anatomy is the study of the structures of the body.
- Different levels of organization range from chemical level to the organismal level.
- Atoms combine to form molecules.
- Molecules combine to form organelles.
- Organelles combine to form cells.
- Similar cells working together form tissues.
- Different tissues working together form organs.
- Different organs working together form organ systems.
- All organ systems working together form the organism or whole body.
Levels of Organization
- Chemical level (atoms, molecules, DNA)
- Cellular level (cells, organelles)
- Tissue level (epithelial, connective, muscle, nervous tissues)
- Organ level (e.g., heart, stomach)
- System level (cardiovascular, digestive)
- Organismal level (human body)
Systems
-
Integumentary System:
- Protection from external environment
- Produces vitamin D
- Retains water
- Regulates body temperature
- Examples include skin, hair,nails.
-
Skeletal System:
- Supports the body
- Protects organs
- Provides leverage for movement (biomechanics)
- Produces blood cells
- Stores calcium salts
- Examples include bones and joints.
-
Muscular System:
- Movement
- Controls body openings
- Generates heat
- Skeletal muscle helps with movement with bones
- Smooth muscle helps move things through the body
- Cardiac muscle helps with heart function
- Examples include skeletal, smooth, and cardiac muscles.
-
Nervous System:
- Regulates many functions, including sensation, movement and higher mental functions
- Central nervous system (brain, spinal cord)
- Example include brain, nerves , spinal cord and sensory organs.
-
Endocrine System:
- Regulates hormones
- Regulate nutrient levels, iron levels, and emotional/behavioral activity
- Examples include pineal , pituitary glands, thyroid, thymus, adrenal glands, pancreas, ovaries and testes .
-
Cardiovascular System:
- Protection: carries immune cells
- Transport: nutrients, ions, wastes, hormones, proteins, O2, CO2
- Temperature regulation: can dump heat to skin.
- Water balance
- Heart as a pump, blood is mostly water (H2O)
- Examples include blood vessels and heart.
-
Lymphatic System:
- Protection: lots of immune cells
- Helps maintain water balance
- Helps absorb fats (fats absorbed via lacteals
- Examples include lymph nodes, thymus, spleen.
-
Respiratory System:
- Delivers oxygen to blood
- Removes CO2 from body
- Maintains acid-base balance of blood
- Examples include lungs, trachea, larynx.
-
Digestive System:
- Digests food
- Absorbs nutrients into the blood
- Removes food waste
- Regulates fluid, electrolyte, acid-base balance
- Examples include mouth, stomach, intestines, liver, etc.
-
Urinary System:
- Removes metabolic waste from the blood
- Regulates fluid, electrolyte, and acid-base homeostasis.
- Stimulates blood cell production
- Examples include kidneys, ureters, bladder and urethra.
-
Reproductive System:
- Produces gametes
- Transports gametes
- Nourishes and protects developing offspring
- Examples include gonads, ducts, and external genitalia
Homeostasis
- The maintenance of a stable internal environment.
- Homeostatic imbalances lead to disease or death.
- Regulatory mechanisms and feedback loops are constantly active in the body.
Directional Terms
- Terms to describe location of body structures relative to one another or to a specific reference point. -Example: anterior, posterior; superior, inferior; medial, lateral
Anatomical Planes
- Sagittal: Dividing the body into left and right sections (midsagittal, parasagittal)
- Frontal (coronal): Dividing the body into front and back sections.
- Transverse (horizontal): Dividing the body into top and bottom sections
- Oblique: Dividing the body at an angle.
Body Cavities
- Dorsal (posterior): Cranial (brain) and vertebral (spinal cord) cavities.
- Ventral (anterior): Thoracic and abdominopelvic cavities, further subdivided into specific compartments.
Membranes
- Serous membranes : line body cavities and cover organs
