Study Notes
Anatomy - Introduction and Terminology
- Anatomy studies the internal and external structures of the body and their relationships
- Types of anatomical studies include:
- Macroscopic: Studying body structures without a microscope
- Surface anatomy: Studying the external body
- Regional anatomy: Studying specific regions of the body
- Systemic anatomy: Studying specific organ systems
- Microscopic: Using microscopes to study smallest structures like cells and tissues
- Cytology: Studying cells
- Histology: Studying tissues
- Macroscopic: Studying body structures without a microscope
Levels of Organization
- Cells: Basic units of structure and function in living things (e.g., blood cells, nerve cells, bone cells)
- Tissues: Groups of similar cells that work together to perform a specific activity (e.g., blood, nervous, bone)
- Organs: Structures made of tissues working together for specific functions (e.g., heart, brain, skin)
- Organ Systems: Groups of two or more tissues that perform a specific function (e.g., nervous system, skeletal system)
- Organisms: A group of organs working together to perform common functions (e.g., respiratory, digestive)
Anatomical Position
- Standard position for describing the human body
- Body standing upright, facing forward, legs parallel, upper limbs hanging at sides, palms facing forward
Directional Terms
- Superior/Cranial: Above or higher on the body
- Inferior: Below or lower on the body
- Caudal: Towards the tail bone (used primarily for the lower body)
- Medial: Toward the midline of the body
- Lateral: Away from the midline of the body
- Superficial: Toward or on the body surface
- Deep: Away from the body surface
Directional Terms (cont.)
- Anterior/Ventral: Front of the body.
- Posterior/Dorsal: Back of the body.
- Proximal: Closer to the point of attachment (for limbs only)
- Distal: Farther from the point of attachment (for limbs only)
Body Planes and Sections
- Sagittal Plane: Divides the body into left and right halves
- Coronal (Frontal) Plane: Divides the body into front and back halves
- Transverse Plane: Divides the body into top and bottom halves
Body Cavities
-
Dorsal Cavity: Protects the nervous system
- Cranial cavity: Houses the brain
- Vertebral cavity: Houses the spinal cord
-
Ventral Cavity: Houses visceral organs
- Thoracic cavity: Houses the lungs and heart
- Abdominal cavity: Houses the stomach and spleen
