Study Notes
Nervous System
- Comprises the brain, spinal cord, nerves, and special senses.
- Functions to transmit messages across different organs and detect environmental changes to prompt responses.
Endocrine System
- Includes the pituitary, thyroid, parathyroid, adrenal, pineal glands, ovaries, testes, and pancreas.
- Responsible for promoting growth, producing chemical messengers (hormones) that travel in the blood, and regulating long-term homeostasis.
Cardiovascular System
- Consists of the heart, blood vessels, and blood.
- Functions as a transport system for nutrients and oxygen, while also providing protection.
Lymphatic/Immune System
- Made up of lymphatic vessels, lymph nodes, spleen, thymus, and tonsils.
- Cleanses blood and retrieves fluids leaked from blood vessels to return them to circulation.
Respiratory System
- Includes the nose, pharynx, larynx, trachea, bronchi, and lungs.
- Responsible for supplying oxygen and removing carbon dioxide from the body.
Digestive System
- Composed of the mouth, esophagus, stomach, small and large intestines, and accessory structures.
- Aids in the breakdown of food for absorption into the bloodstream.
Urinary System
- Consists of kidneys, urethra, urinary bladder, and urethra.
- Maintains the balance of water, electrolytes, and acid-base levels in blood.
Reproductive System
- Male: testes, scrotum, penis, sperm duct; Female: ovaries, fallopian tubes, uterus, vagina.
- Functions include the production of sperm and egg cells and facilitating fertilization.
Homeostasis
- Refers to a dynamic equilibrium where internal conditions fluctuate but remain within narrow limits to maintain balance.
Anatomy
- A subdivision of biology focused on the structure and shape of body parts and their interrelations.
- Derives from Greek terms: "Ana" (apart) and "tomy" (to cut).
Physiology
- The study of how body parts work and function.
- Originates from Greek: "Physio" (nature) and "ology" (the study of).
Relationship Between Anatomy & Physiology
- Body parts function as a well-organized unit, each having specific roles to support overall operation.
Levels of Study in Anatomy
- Gross Anatomy: Involves large structures observable without instruments.
- Microscopic Anatomy: Focuses on very small structures that require a microscope for viewing.
Structural Organization of the Body
- Levels: Cell → Tissue → Organ → Organ System.
Organ Systems Overview
- Includes Integumentary, Skeletal, Muscular, Nervous, Endocrine, Cardiovascular, Respiratory, Digestive, Excretory, and Reproductive systems.
Integumentary System
- Consists of skin, nails, hair, sensory organs, and glands.
- Functions include protection, excretion of salts and urea, and temperature regulation.
Skeletal System
- Composed of bones, cartilages, tendons, ligaments, and joints.
- Provides support, protects organs, enables muscular leverage, stores minerals, and facilitates blood cell formation.
Muscular System
- Comprises muscles attached to bones allowing movement.
Anterior Body Landmarks
- Abdominal: tummy
- Anticubital: elbow anterior
- Brachial: arms
- Inguinal: groin
- Thoracic: chest
Posterior Body Landmarks
- Gluteal: buttocks
- Lumbar: lower back
- Occipital: base of skull
- Vertebral: spinal column area
Body Planes & Sections
- Sagittal/Midsagittal Plane: divides body into left/right parts.
- Frontal/Coronal Plane: divides body into anterior/posterior.
- Transverse/Cross-section Plane: divides body into superior/inferior.
Body Cavities
- Dorsal: Cranial (brain) and Spinal (spinal cord).
- Ventral: Thoracic (heart and lungs), Abdominal (digestive organs), Pelvic (reproductive organs).
Abdominal Pelvic Quadrants
- Divided into upper and lower quadrants for organizational purposes.
9 Abdominopelvic Regions
- Right/Left Hypochondriac, Epigastric, Right/Left Lumbar, Right/Left Iliac, and Umbilical regions.
Body Membranes
- Epithelial tissue membranes include:
- Cutaneous membrane: skin composed of keratinized stratified epithelium.
