Study Notes
Anatomy and Physiology
- Anatomy: Studies the structure and parts of the body.
- Physiology: Studies the function and workings of body parts.
Levels of Organization
- Chemical level: Simplest level, involving atoms and molecules.
- Cellular level: Cells are the basic units of life.
- Tissue level: Groups of similar cells form tissues.
- Organ level: Tissues combine to form organs.
- Organ system level: Organs working together form organ systems.
- Organism level: Highest level, encompassing all organ systems.
Characteristics of Life
- Growth: Increase in size and cell number.
- Reproduction: Ability to produce offspring.
- Responsiveness: Reaction to environmental changes.
- Movement: Motion of the body or its parts.
- Metabolism: Chemical reactions providing energy.
- Homeostasis: Maintaining a stable internal environment.
Homeostasis
- Homeostasis: Maintaining a stable internal environment.
- Receptors: Detect changes in internal/external conditions.
- Set point: Normal range or value for a variable.
- Effectors: Organs/tissues that correct deviations from the set point.
- Negative feedback: Reduces or reverses the original stimulus (e.g., body temperature).
- Positive feedback: Amplifies or increases the original stimulus (e.g., childbirth).
Body Divisions
- Axial portion: Head, neck, and trunk.
- Cranial cavity: Houses the brain.
- Spinal cavity: Contains the spinal cord.
- Thoracic cavity: Houses lungs and heart.
- Abdominopelvic cavity: Contains digestive and reproductive organs.
- Appendicular portion: Limbs and connective structures (shoulders, hips).
Body Cavities and Membranes
- Pleural membranes: Line the lungs.
- Pericardial membranes: Surround the heart.
- Peritoneal membranes: Line the abdominal cavity and cover its organs.
Organ Systems
- Integumentary system: Skin, hair, nails; Protection and regulation of temperature.
- Skeletal system: Bones and cartilage; Support and protection of organs.
- Muscular system: Skeletal muscles; Movement.
- Nervous system: Brain, spinal cord, and nerves; Control and coordination.
- Endocrine system: Glands; Hormone production and regulation.
- Cardiovascular system: Heart and blood vessels; Blood circulation.
- Lymphatic system: Lymph nodes and spleen; Immunity.
- Respiratory system: Lungs and trachea; Gas exchange.
- Digestive system: Stomach and intestines; Food breakdown and nutrient absorption.
- Urinary system: Kidneys and bladder; Waste removal and water balance.
- Reproductive system: Ovaries and testes; Reproduction.
Anatomical Position and Terms
- Anatomical position: Standing erect, facing forward, arms at sides, palms forward.
- Superior: Above.
- Inferior: Below.
- Anterior (ventral): Front.
- Posterior (dorsal): Back.
- Medial: Toward the midline.
- Lateral: Away from the midline.
- Bilateral: Both sides.
- Ipsilateral: Same side.
- Proximal: Closer to the point of attachment.
- Distal: Further from the point of attachment.
- Superficial (peripheral): Near the surface.
- Deep: Away from the surface.
Anatomical Sections
- Sagittal section: Divides the body into left and right.
- Transverse section (cross section): Divides the body into upper and lower parts.
- Frontal section (coronal section): Divides the body into front and back parts.
- Cross section: Perpendicular cut.
- Oblique section: Cut at an angle.
- Longitudinal section: Lengthwise cut.
Abdominal Regions and Quadrants
- Nine regions: Right hypochondriac, epigastric, left hypochondriac; Right lumbar, umbilical, left lumbar; Right iliac, hypogastric, left iliac.
- Four quadrants: Right upper quadrant (RUQ), left upper quadrant (LUQ), right lower quadrant (RLQ), left lower quadrant (LLQ).
