Study Notes
Membranes
-
Mucosa types include nasal cavity, mouth, esophagus, and lung bronchi, each serving specialized functions.
-
Serous membranes line closed body cavities and consist of two layers: the visceral layer covering organs and the parietal layer covering cavity walls.
-
Three main serous membranes:
- Pleura: Covers lungs and lines pleural cavities.
- Peritoneum: Lines the abdominal cavity and covers abdominal organs.
- Pericardium: Surrounds the heart and lines the pericardial cavity.
-
A potential space, or cavity, exists between visceral and parietal layers, allowing for organ movement and reducing friction.
Cutaneous and Synovial Membranes
-
Cutaneous membrane (skin) is thick, waterproof, and dry; plays a role in regulating bodily functions.
-
Synovial membranes lines joint cavities, producing synovial fluid for lubrication and protecting bone ends.
Anatomical Terminology
- Anatomical position: standard reference where the body is upright, feet together, palms facing forward, and face forward.
Position and Directional Terms
- Superior: Closer to the head.
- Inferior: Closer to the feet.
- Medial: Closer to the midline.
- Lateral: Further from the midline.
- Anterior: More in front.
- Posterior: More in back.
- Proximal/Distal: Closer to/further from the limb root.
- Superficial/Deep: Closer to the surface/closer to the interior.
- Ventral: Towards the front.
- Dorsal: Towards the back.
- Prone: Lying face down; Supine: Lying face up.
- Unilateral: One side; Bilateral: Both sides; Contralateral: Opposite sides.
Terms of Movement
- Flexion/Extension: Decreasing/increasing joint angle.
- Hyperextension: Excessive extension beyond normal limits.
- Abduction/Adduction: Moving away/towards the midline.
- Pronation/Supination: Turning palm/foot down/up.
- Retraction/Protraction: Moving backward/forward.
- Elevation/Depression: Raising/lowering a part.
- Rotation/Circumduction: Turning on an axis/circular motion in joints.
- Inversion/Eversion: Turning the sole of the foot inward/outward.
- Dorsiflexion/Plantarflexion: Foot movement towards the shin/pointing downwards.
- Radial/Ulnar Deviation: Wrist movement towards the radius/ulna.
- Opposition: Movement of the thumb across the palm.
Characteristics of the Human Body
- Homeostasis: Maintenance of stable internal conditions.
- Development: Growth through cell number and size increase.
- Differentiation: Unspecialized cells becoming specialized.
- Reproduction: Formation of new individuals.
- Evolution: Genetic changes in populations over time.
Levels of Organization
- Atoms, Molecules, Organelles, Cells, Tissues, Organs, Organ Systems, Organism: Hierarchical structure of biological life.
Organ Systems Overview
- Integumentary System: Skin, hair, and nails; protects and regulates temperature.
- Skeletal System: Bones and ligaments; provides support and protection.
- Muscular System: Skeletal muscles; enables movement and heat generation.
- Nervous System: Brain and nerves; processes sensory information and directs responses.
- Endocrine System: Glands that regulate long-term changes and metabolism.
- Cardiovascular System: Heart and blood vessels; circulates blood and regulates temperature.
- Lymphatic System: Spleen and lymph nodes; defends against disease and returns fluid to blood.
- Respiratory System: Nasal cavities and lungs; facilitates gas exchange.
- Digestive System: Organs from mouth to intestines; processes food and absorbs nutrients.
- Urinary System: Kidneys and bladder; excretes waste and regulates water balance.
- Reproductive System: Specialized organs; responsible for producing offspring.
