Study Notes
Body Planes
- Coronal Plane: Divides the body into dorsal (back) and ventral (front) parts.
- Transverse Plane: Splits the body into superior (upper) and inferior (lower) sections.
- Sagittal Plane: Separates the body into right and left parts.
- Midsagittal Plane: Creates two equal halves (left and right).
- Oblique Plane: Any angle that is not strictly horizontal or vertical.
Directional Terms (General Orientation)
- Anterior/Ventral: Pertains to the front of the body.
- Posterior/Dorsal: Relates to the back of the body.
- Deep: Indicates a position far from the surface.
- Superficial: Signifies proximity to the skin or surface.
Directional Terms (Positioning)
- Medial: Toward the midline of the body.
- Lateral: Away from the midline of the body.
- Proximal: Closer to the trunk or origin of a body part.
- Distal: Farther from the trunk or origin of a body part.
Body Regions (Frontal View)
- Left Side Regions: Cervical (neck), Axillary (armpit), Cubital (elbow), Antebrachial (forearm), Crural (leg).
- Right Side Regions: Deltoid (shoulder), Brachial (arm), Inguinal (groin), Femoral (thigh).
Body Regions (Posterior View)
- Occipital: Back of the head.
- Acromial: Shoulder area, associated with the bony process of the scapula.
- Gluteal: Relates to the gluteus muscles (buttocks).
- Popliteal: Area behind the knee.
- Heel: Back part of the foot, below the ankle.
Body Systems
- Digestive System: Breaks down food and absorbs nutrients.
- Integumentary System: Protects the body (skin, hair, nails).
- Endocrine System: Regulates hormones.
- Muscular System: Facilitates movement and stability.
- Lymphatic System: Supports immune function and fluid balance.
Additional Body Systems
- Skeletal System: Provides structure and support.
- Nervous System: Controls and coordinates movement and responses.
- Respiratory System: Facilitates gas exchange (oxygen and carbon dioxide).
- Circulatory System: Transports blood, nutrients, and gases.
- Urinary System: Eliminates waste and regulates water balance.
Body Cavities (Superior to Inferior)
- Cranial Cavity: Contains the brain.
- Thoracic Cavity: Houses the heart and lungs.
- Abdominal Cavity: Encloses digestive organs.
- Pelvic Cavity: Contains reproductive and urinary organs.
Digestive Tract Order
- Oral Cavity: Entry point for food.
- Pharynx: Connects mouth to esophagus.
- Esophagus: Transports food to the stomach.
- Stomach: Digests food before entering the intestines.
- Small Intestine: Absorbs nutrients.
- Large Intestine: Consolidates waste for elimination.
