Study Notes
Anatomy and Physiology Overview
- Anatomy is the study of the structure of an organism, including size, shape, construction, and organ positions.
- Physiology is the study of the functions of an organism, how organs work independently and as a whole.
Anatomical Position
- Anatomical position: Person stands erect, facing forward, feet forward and apart, arms hanging down, palms forward. A standardized view for consistent anatomical descriptions.
Body Planes
- Median plane: Divides the body into right and left halves.
- Sagittal plane: Divides the body parallel to the median plane.
- Coronal (frontal) plane: Divides the body into front and back portions.
- Transverse plane: Divides the body into upper and lower portions.
- Oblique plane: Divides the body at an angle.
Directional Terms
- Superior: Above
- Inferior: Below
- Anterior: Front
- Posterior: Back
- Proximal: Closer to the point of attachment
- Distal: Farther from the point of attachment
- Medial: Toward the midline
- Lateral: Away from the midline
- Internal: Inside
- External: Outside
- Deep: Further from the surface
- Superficial: Closer to the surface
- Central: Located in the center
- Peripheral: Located towards the outside
- Parietal: Referring to the membrane lining the body cavity.
- Visceral: Referring to the membrane covering the organs.
- Cephalic: Referring to the head.
- Caudal: Referring to the tail or tail end.
- Palmar: Referring to the palm of the hand.
- Plantar: Referring to the sole of the foot.
- Greater curvature: Outer and longer portion of a curved structure.
- Lesser curvature: Inner and shorter portion of a curved structure.
- Erect: Standing or sitting upright.
- Supine: Lying face up (dorsal recumbent position, for anterior surgeries).
- Prone: Lying face down
- Lateral: Lying on one side
Body Regions
- Head: Contains brain, components of mouth, nose, eyes, ears, and glands.
- Trunk: Includes neck, back, chest, abdomen, pelvis, perineum and vital organs.
- Limbs: Include arms, legs, hands, and feet (non-essential for life).
Body Cavities
- Cranial cavity: Houses the brain and pituitary gland.
- Spinal cavity: Contains spinal cord.
- Pleural cavities: Contain one lung each.
- Pericardial cavity: Contains the heart.
- Mediastinal space: Contains the thymus gland, trachea, esophagus, bronchi, ends of the vena cavae, beginning of the aorta.
- Abdominal cavity: Holds the stomach, liver, gallbladder, spleen, pancreas, most of the intestines, kidneys.
- Pelvic cavity: Houses the urinary bladder, sex organs, part of the large intestine (cecum, appendix, rectum).
Abdominopelvic Quadrants
- Right upper quadrant (RUQ): Part of the small intestine, upper ascending colon, most of the liver, gallbladder, bile ducts, head of the pancreas, right adrenal gland, right kidney, upper part of the right ureter.
- Left upper quadrant (LUQ): Ascending part of the duodenum, upper descending colon, left half transverse colon, spleen, small part of the liver, left adrenal gland, left kidney, upper part of the left ureter, stomach.
- Right lower quadrant (RLQ): Lower ascending colon, cecum, appendix, lower right ureter, terminal ileum, part of the urinary bladder, sex organs.
- Left lower quadrant (LLQ): Lower descending colon, small intestine (part of ileum), part of the urinary bladder, sex organs.
Body Structure Organization
- Cell: Fundamental unit
- Tissue: Group of cells
- Organ: Group of tissues
- Organ system: Group of organs
- Organism: Complete living entity
Major Organ Systems
- Integumentary system: External protection, temperature regulation, sensation, waste excretion
- Skeletal system: Support and protection
- Muscular system: Movement and support
- Nervous system: Coordination and communication
- Special senses: Sight, smell, hearing, and taste
- Digestive system: Processes food
- Circulatory system: Transports materials
- Respiratory system: Gas exchange (oxygen and carbon dioxide)
- Urinary system: Waste removal
- Reproductive system: Reproduction
- Endocrine system: Regulation through hormones
- Immune system: Defense against disease
Organ System Components
- Integumentary: Skin, hair, nails, glands
- Skeletal: Bones, joints, cartilage, connective tissue
- Muscular: Skeletal, smooth, and cardiac muscles
- Nervous: Brain, spinal cord, peripheral nerves
- Special Senses: Eyes, ears, nose, taste buds
