Study Notes
Overview
Anatomy is the study of the structure and organization of living things, including their systems, organs, and tissues.
Levels of Organization
- Chemical level: atoms and molecules
- Tissue level: groups of similar cells
- Organ level: structures composed of multiple tissues
- Organ system level: groups of organs working together
- Organismal level: the entire living thing
Body Regions
- Cranial region: head and skull
- Facial region: face
- Neck region: neck
- Thoracic region: chest
- Abdominal region: abdomen
- Pelvic region: pelvis
- Upper limb region: arms
- Lower limb region: legs
- Back region: back
Body Cavities
- Cranial cavity: contains the brain
- Thoracic cavity: contains the heart and lungs
- Abdominal cavity: contains digestive organs
- Pelvic cavity: contains reproductive organs and urinary bladder
Directional Terms
- Anterior (front)
- Posterior (back)
- Superior (above)
- Inferior (below)
- Medial (toward the midline)
- Lateral (away from the midline)
- Proximal (close to the attachment)
- Distal (far from the attachment)
Anatomical Position
- Feet shoulder-width apart
- Toes pointing forward
- Arms at sides
- Palms facing forward
- Head, eyes, and toes facing forward
Anatomical Planes
- Sagittal plane: divides the body into left and right halves
- Frontal plane: divides the body into anterior and posterior halves
- Transverse plane: divides the body into superior and inferior halves
