Study Notes
Anatomy
- The study of the structure of the human body
- Closely related to physiology, the study of the function of the human body
Divisions of Anatomy
- Gross Anatomy: Study of structures visible to the naked eye (e.g., muscles, bones, organs)
-
Microscopic Anatomy: Study of structures requiring a microscope (e.g., cells, tissues)
- Cytology: Study of cells
- Histology: Study of tissues
Ways to Study Anatomy
- Regional Anatomy: Examining one region of the body at a time, focusing on all its components
- Systemic Anatomy: Examining one body system at a time (the approach used in this course)
Anatomical Organization
-
Hierarchy of Organization:
- Cells: The basic unit of life
- Tissues: Groups of similar cells working together
- Organs: Structures composed of different tissues, performing a specific function
- Organ Systems: Groups of organs working together to perform a particular function
- Organism: A complete living being composed of multiple organ systems
Organ Systems
- Integumentary System: Skin, hair, nails - protection, temperature regulation
- Skeletal System: Bones, cartilage, ligaments - support, movement, protection
- Muscular System: Muscles - movement, heat production
- Nervous System: Brain, spinal cord, nerves - communication, control
- Endocrine System: Glands (e.g., pituitary, thyroid, pancreas) - hormone production
- Cardiovascular System: Heart, blood vessels - transport of blood, nutrients, oxygen
- Lymphatic System: Lymphatic vessels, lymph nodes, spleen - fluid balance, immunity
- Respiratory System: Lungs, trachea, bronchi - gas exchange
- Digestive System: Mouth, esophagus, stomach, intestines - digestion and absorption
- Urinary System: Kidneys, bladder, ureters - waste removal, fluid balance
- Reproductive System: Male and female reproductive organs - reproduction
Anatomical Directions
-
Four-footed body directions:
- Anterior: Front
- Posterior: Behind
- Dorsal: Back
- Ventral: Belly
Planes and Sections
-
Sagittal Section: Divides the body into right and left sides
- Mid-sagittal Section: Divides the body straight down the center
- Frontal Section: Divides the body into front and back sides
- Transverse Section (Cross Section): Divides the body straight across
Body Cavities
-
Dorsal Cavity: Houses the brain and spinal cord
- Cranial Cavity: Contains the brain
- Vertebral Cavity: Contains the spinal cord
-
Ventral Cavity: Houses organs of the chest and abdomen
- Thoracic Cavity: Houses the heart and lungs
-
Abdominopelvic Cavity: Houses digestive, reproductive, and urinary organs
- Abdominal Cavity: Upper portion containing digestive organs
- Pelvic Cavity: Lower portion containing reproductive and urinary organs
Body Quadrants
- Right Upper Quadrant (RUQ)
- Left Upper Quadrant (LUQ)
- Right Lower Quadrant (RLQ)
- Left Lower Quadrant (LLQ)
Anatomy
- Anatomy: The study of the structure of the human body
- Physiology: The study of the function of the human body
- Anatomy and Physiology are closely related
Divisions of Anatomy
- Gross Anatomy: The study of structures visible to the naked eye, like muscles, bones, and organs
-
Microscopic Anatomy: The study of structures too small to be seen without a microscope
- Cytology: The study of cells
- Histology: The study of tissues
Ways to Study Anatomy
- Regional Anatomy: Focuses on studying one region of the body at a time, examining all its structures
- Systemic Anatomy: Studies one body system at a time, like the skeletal or muscular systems
Anatomical Organization
- Cells: The fundamental units of life, forming tissues
- Tissues: Groups of similar cells working together, forming organs
- Organs: Structures composed of different tissues, performing specific functions
- Organ Systems: Groups of organs working together, like the digestive or circulatory
- Organism: A complete living being composed of all the organ systems
Organ Systems
- Integumentary System: Skin, hair, nails, responsible for protection and temperature regulation
- Skeletal System: Bones, cartilage, ligaments, providing support, protection, and movement
- Muscular System: Muscles, responsible for movement, posture, and heat production
- Nervous System: Brain, spinal cord, nerves, responsible for communication, control, and coordination
- Endocrine System: Glands that secrete hormones, regulating growth, metabolism, and mood
- Cardiovascular System: Heart, blood vessels, responsible for transporting blood and oxygen
- Lymphatic System: Lymph vessels, lymph nodes, responsible for immune function and fluid balance
- Respiratory System: Lungs, trachea, bronchi, responsible for gas exchange (oxygen intake and carbon dioxide removal)
- Digestive System: Mouth, stomach, intestines, responsible for breaking down food and absorbing nutrients
- Urinary System: Kidneys, ureters, bladder, urethra, responsible for filtering blood and producing urine
- Reproductive System: Male: testes, prostate, penis; Female: ovaries, uterus, vagina, responsible for sexual reproduction
Body Directions - Four-Footed
- Anterior/Ventral: Towards the front
- Posterior/Dorsal: Towards the back
- Superior/Cranial: Towards the head
- Inferior/Caudal: Towards the tail
Planes and Sections
-
Sagittal Section: Divides the body into right and left halves
- Mid-Sagittal Section: Divides the body exactly in the middle, creating equal right and left sides
- Frontal Section (Coronal): Divides the body into front (anterior) and back (posterior) sections
- Transverse Section (Cross): Divides the body into upper (superior) and lower (inferior) sections
Body Cavities
-
Dorsal Body Cavity: Encases the nervous system
- Cranial Cavity: Contains the brain
- Vertebral Cavity: Contains the spinal cord
-
Ventral Body Cavity: Houses the internal organs
- Thoracic Cavity: Contains heart and lungs
- Abdominopelvic Cavity: Contains digestive organs, reproductive organs, and urinary organs
Body Quadrants
- Right Upper Quadrant (RUQ): Contains the liver, gallbladder, and part of the stomach
- Left Upper Quadrant (LUQ): Contains the stomach, spleen, and part of the pancreas
- Right Lower Quadrant (RLQ): Contains the appendix, part of the small intestine, and part of the large intestine
- Left Lower Quadrant (LLQ): Contains the left part of the small intestine, part of the large intestine, and the descending colon
