Study Notes
Anatomy and Physiology Overview
- Anatomy studies body structure; physiology examines body function.
- Anatomical position: body standing upright, facing forward with arms at the sides and palms facing forward.
- Prone position: body lying face down.
- Supine position: body lying face up.
Directional Terms
- Superior: Towards the head
- Inferior: Away from the head
- Medial: Nearer to the midline
- Lateral: Further from the midline
- Anterior (ventral): Front of the body
- Posterior (dorsal): Rear of the body
- Proximal: Nearer to attachment point of limb to trunk
- Distal: Further from attachment point of limb to trunk
- Superficial: On or near body or organ surface
- Deep: Further away from body or organ surface
- Central: Towards the core, usually head and trunk
- Peripheral: Towards body extremities
Cellular and System Definitions
- Cells: Basic structural and functional units of organisms.
- Tissues: Groups of similar cells performing a specific function.
- Organs: Composed of multiple tissue types with specific functions.
- Body Systems: Consist of related organs sharing a common function.
- Homeostasis: Stability or balance in the body's internal environment.
Body Regions and Cavities
- Abdominopelvic region divided into four quadrants or nine regions, important for abdominal assessments.
- Body cavities protect and support internal organs.
- Stomach: Abdominal cavity
- Heart: Thoracic cavity
- Lungs: Thoracic cavity
- Brain: Cranial cavity
- Small Intestine: Abdominal cavity
- Urinary Bladder: Pelvic cavity
- Kidneys: Abdominal cavity
- Liver: Abdominal cavity
Cavity Boundaries
- Cranial cavity: Bounded by cranial bones.
- Vertebral cavity: Bounded by the spinal column.
-
Thoracic cavity:
- Superior: base of neck
- Inferior: diaphragm
- Anterior: sternum and costal cartilage
- Posterior: thoracic vertebrae and ribs
-
Abdominal cavity:
- Superior: diaphragm
- Anterior: abdominal muscles
- Posterior: vertebrae
-
Pelvic cavity:
- Superior: symphysis pubis and sacrum
- Inferior: pelvic floor muscles
- Anterior: symphysis pubis and pelvic bone
- Posterior: pelvic bones, sacrum, and coccyx
- Lateral: pelvic bones
Body Planes
- Parasagittal plane: Divides the body into left and right parts.
- Midsagittal plane: Separates body into two equal left and right portions.
- Frontal plane: Divides into anterior (front) and posterior (back) sections.
- Transverse (horizontal) plane: Divides into superior (upper) and inferior (lower) sections.
Body Systems and Functions
- Integumentary System: Comprises skin, hair, nails, and glands; functions include protection, sensation detection, waste excretion, vitamin D synthesis, fat storage, and temperature regulation.
- Skeletal System: Includes bones, ligaments, and joints; functions to protect and support body organs and provide movement framework.
