Study Notes
Introduction to the Human Body
- Anatomy is the scientific study of the body's structures.
- Physiology is the study of the body's chemistry and physics, focusing on its functions.
- Anatomy is the study of the internal and external structures.
- Anatomy can be gross or microscopic.
- Gross anatomy examines large structures.
- Microscopic anatomy examines structures needing magnification.
Chapter Objectives
- Students will distinguish between anatomy and physiology.
- They will identify several branches of each.
- Students will describe body structure, from simplest to complex.
- Define homeostasis and explain its importance.
- Use anatomical terminology to identify key body structures.
Overview of Anatomy and Physiology
- The section introduces general details about anatomy and physiology.
Anatomy
- Anatomy involves dissecting structures within the body.
- Gross anatomy examines large structures.
- Microscopic anatomy examines structures needing magnification.
- These subdivisions include areas dealing with individual organs or organ systems.
Gross Anatomy
- Gross anatomy involves examining relatively large structures.
- Several approaches include surface anatomy, regional anatomy, and systemic anatomy
Microscopic Anatomy
- Microscopic anatomy examines structures requiring magnification.
- Cytology studies body cells.
- Histology studies tissues.
Subdivisions of Anatomy
- Gross anatomy examines large structures, such as the brain.
- Microscopic anatomy examines smaller structures, like cells within the brain.
Physiology
- Physiology covers the functions of the body.
- It is more complex than anatomy.
- Physiology studies how structures work together.
- It is closely linked to anatomy.
- Physiology examines organs or organ systems.
Structural Organization of the Human Body
- This section details the organization of the human body.
Levels of Organization
- Chemical level - atoms and molecules.
- Cellular level - cells, the basic units.
- Tissue level - tissues made of similar cells.
- Organ level - organs formed by tissues.
- Organ system level - systems made of multiple organs.
- Organism level - the whole human being.
Integumentary System
- Organs include skin, hair, and nails.
- Functions of the integumentary system include external support and protection.
Skeletal System
- Organs include bones, cartilage, and joints.
- Its functions include internal support, organ protection, framework for movement, and mineral storage.
Muscular System
- Organs include skeletal muscles and tendons.
- Functions include locomotion, support (internal and external), and body heat production.
Nervous System
- Organs include the brain, spinal cord, and peripheral nerves.
- Functions include detecting sensory information, processing information, and directing responses.
Endocrine System
- Organs include various hormone-secreting glands.
- Functions include hormone secretion controlling bodily processes.
Circulatory System
- Organs include the heart, blood, and blood vessels.
- Functions consist of nutrient transport, waste removal, and body temperature regulation.
Lymphatic and Immune System
- Organs include lymph nodes, lymphatic vessels, spleen, thymus, bone marrow, and tonsils.
- Functions include returning fluid to the blood, defending against pathogens, and providing immunity.
Respiratory System
- Organs include lungs, trachea, larynx, and nasal passages.
- Functions consist of gas exchange, oxygen delivery, and carbon dioxide removal.
Digestive System
- Organs include salivary glands, esophagus, stomach, small intestine, large intestine, liver, and gallbladder.
- The digestive system breaks down food and releases nutrients, vitamins, and water into the body.
Urinary System
- Organs consist of kidneys, ureters, urinary bladder, and urethra.
- Functions include controlling water balance, filtering blood, and removing waste products.
Reproductive System- Male
- Organs include testes, scrotum, prostate gland, seminal vesicles, epididymis, and penis.
- Functions include sperm production and delivery, and sex hormone production.
Reproductive System- Female
- Organs include ovaries, uterus, vagina, and mammary glands.
- Its functions include egg production, hormone secretion, copulation, and fetal/infant support.
Homeostasis
- Maintaining a stable internal environment is crucial.
- A series of three components (receptor, control center, effector) are necessary to achieve this.
- Homeostatic mechanisms employ negative and positive feedback processes.
Homeostatic Regulation
- Homeostasis is achieved through negative and positive feedback mechanisms.
- Negative feedback loops reverse the initial stimulus.
- Positive feedback loops increase the initial stimulus.
Positive Feedback
- A mechanism creating a self-amplifying cycle.
- An example is childbirth.
Anatomical Terminology
- Used to accurately identify body structures and directions.
Anatomical Position
- This standardized position allows for consistent use of anatomical terms.
Directional Terms
- Terms used to describe locations relative to other structures.
- These include superior/inferior, cranial/caudal, posterior/anterior, dorsal/ventral, right/left, lateral/medial, proximal/distal, and superficial/deep.
Regions of the Human Body
- Detailed definitions of body regions (e.g., frontal, cephalon, thoracic, lumbar, abdominal...).
Body Planes
- Sagittal plane divides the body into left and right halves.
- Frontal plane divides the body into front and back halves.
- Transverse plane divides the body into top and bottom halves.
- These are used for descriptive purposes.
Body Cavities
- The body has many cavities (e.g.; cranial, thoracic, abdominal, pelvic).
- The cavities contain internal organs.
Serous Membranes
- Body cavities are lined with membrane layers.
- Functions include fluid secretion and prevention of friction.
Abdominal Regions and Quadrants
- Dividing the abdominal region into sections (nine regions or four quadrants).
- Used for identifying areas of pain or abnormality during medical diagnosis.
Citation
- The source of the images and text used in the slides.
